Potato planting rate per 1 hectare and hundred square meters (in pcs. and kg)

Calculation of potato seeding rate

The most important thing in planting potatoes is to comply with the early sowing dates.
Meeting the deadlines contributes to the formation of a powerful root system and well-developed tops, which will invariably lead to a high yield. Well-developed plants are characterized by rapid tuber formation and achievement of full maturity. This is an integral factor in early harvesting with minimal losses that accompany late harvesting.

Well-developed plants are characterized by rapid tuber formation and achievement of full maturity. This is an integral factor in early harvesting with minimal losses that accompany late harvesting.

Potatoes, as a valuable food product, occupy a dominant place among agricultural crops. Not a single table is complete without its presence, as in its own form: baked, boiled, fried potatoes; and as a main and auxiliary component, for the preparation of side dishes, salads and soups.

Principles of selection of planting material

The main principle of planting a crop is the correct calculation of the potato seeding rate. A modern summer resident, equipped with various types of innovative technology, often cannot make the correct calculation of the material required for planting. The careful selection of material for planting consists of several points:

Using undamaged, smooth and healthy tubers to obtain seed material.
Sorting of planting material into large, medium and small fractions*.
Calculation of potato seeding rates.

Note: * when sorting potatoes by size, remember that the amount of planting material is directly proportional to the size of the tuber.

Principles for calculating planting material standards

As an example, let’s calculate the seeding rate of potatoes on one hundred square meters of land or one hundred square meters:

The size of the rectangular plot is: 12.5m in length and 8m in width;
the beds are placed in the direction from south to north;
the plot contains 10 rows; distance between rows – 80 cm; the length of each bed is 125 m;
when planting, the distance between tubers is 10 cm from each other;
each tuber should weigh on average 200-300 g and contain at least 5 eyes.

We make calculations:

row length (125 cm), multiplied by 10 planting rows, you get 1250 pieces;
1250 pcs. need to be divided into 5 eyes, as a result we get 250 tubers.

Conclusion: for one hundred square meters of land, the norm for sowing potatoes is 250 tubers.

Calculations of potato seeding rates for large sown areas are carried out in a similar way. To calculate the planned yield, the number of seed tubers planted on an area of 1 hectare is multiplied by the average weight of potatoes.

Instructions for doing your own calculations

Anyone can calculate the seeding rate for potatoes, even if there are no agronomic tables at hand. To do this, it is important to know the average weight of the tuber and the planting density recommended in specific conditions.

Let us recall the values of the second indicator:

65–70 thousand/ha – for small potatoes (25–50 g);
55–65 thousand/ha – for tubers of the middle fraction (50–80 g);
40–55 thousand/ha – for large specimens (80–100 g).

The calculation rate for potatoes per 1 hectare is determined by the formula:

H = G × M,

where N is the planting rate (t/ha), G is the planting density (thousand/ha), M is the mass of the tuber (g).

Example

For clarity, let’s calculate the seeding rate for potatoes of the Bellarosa variety using the traditional method of growing in one ridge.

We will use tubers with an average weight of 90 g as seed material. The planting density at this weight is 40–55 thousand/ha. However, the variety is early ripening and requires denser planting. Therefore, we will focus on the upper limit - 55 thousand/ha.

Then the planting rate (N) = 55 (G) × 90 (M) = 4950 kg/ha = 4.95 t/ha.

Potato seeding rate

When growing potatoes on an industrial scale, agronomic tables are used to calculate the norm. They take into account in detail the sowing distances of plants in a row, the size of row spacing, the weight of the tuber, and in some cases, the variety. Calculations are based on mathematical formulas.

Per 1 hectare in tons

The seeding rate directly depends on the size of the seed and planting density. The row spacing is determined by the dimensions of the agricultural machinery and most often is 70 cm. The planting interval in the ridge ranges from 15 to 45 cm.

Average potato seeding rates per 1 hectare in tons with a distance between plants in a row of 30 cm:

standard tuber size (50–60 g) - from 2.3 to 2.8 tons of seed material will be required;
fine fraction (30–40 g) - from 1.9 to 2.4 tons;
large (80–90 g) – 3.8–4.3 t.

The value varies depending on climatic conditions, soil fertility, and varietal characteristics. Calculations are made with some margin, taking into account errors in the size of potatoes and their possible rejection.

Per 1 hundred square meters in kilograms

On small farms and household plots, the seeding rate is calculated in kilograms, since it is more convenient to use “running” weight measures.

Let us give a variant of this calculation for a plot of 10 × 10 m (1 hundred square meters) in the form of a square, with a width between rows of 70 cm, a distance between tubers of 40 cm, and a weight of one - 80 g:

number of rows - 14;
row length - 10 m, each with 28 tubers;
In total, it will be possible to plant 392 plants on one hundred square meters (14×28=392).

How many potatoes are needed for planting in this case: 392 × 80 (weight of one tuber) = 31360 g = 31.4 kg.

How to determine potato consumption

Calculation of seeding rates is not 100% accurate. The obtained indicators in reality often deviate significantly both upward and downward.

What does it depend on

Potato consumption directly depends on its size. Large tubers weighing 80–90 g require a large feeding area and are planted in rows with an interval of 35–40 cm, and small ones - at 25–30 cm. The more homogeneous the fraction of the seed, the more reliable the calculations of planting consumption will be.

Reference. If there is a shortage of seed material in small farms, pre-cut large healthy tubers weighing at least 80–100 g are used. Each part should weigh 40–50 g and have at least 2 eyes.

The climatic conditions of the region also affect the consumption of seed material. In the northern regions, the Urals and Siberia, large potatoes weighing 80–100 g are used. Due to the supply of nutrients, they produce healthier seedlings and are able to withstand the vagaries of the weather. In the southern regions, a smaller fraction is planted.

Soil type and fertility play a significant role. The better the soil is fertilized, the more plants can be planted on it. However, excessive compaction of plantings will cause the tubers to grow small.

Ways to increase productivity

To exceed the average yield values and get the maximum number of potatoes per hundred square meters, you can use methods that increase this indicator. The results of crop cultivation are positively influenced by:

quality of “seed” potatoes;
proper preparation of planting material;
use of special technologies;
compliance with crop rotation;
proper organization of watering;
soil nutritional value and fertilizing volumes;
organizing activities to eliminate pests and diseases.

Special techniques

To increase productivity, several special techniques have been developed:

Mittlider method. Planting is done in beds 1.5 m wide with a distance of 1 m. Earthen mounds are organized around the planting to retain moisture. Regular watering and three-time application of fertilizers make it possible to achieve high potato yields per hectare - 55 tons.
Gülich method. 1 m2 is allocated for each plant. The planting hole is filled with humus, and a large root crop is planted in it, top down. High-quality watering is organized; when shoots appear, soft soil is poured into the center of each plant, and the stems are pulled to the sides. As it grows, the manipulation is repeated, which helps to form a multi-tiered bush that produces up to 16 kg of tubers.
Dutch technology. High-yielding Dutch varieties are used for planting; the beds are located in the North-South direction. Embankments with a height of 25 cm are organized with a distance of 80 cm, into which planting material with a diameter of 3-5 cm is planted. 2 weeks before harvesting, the tops are removed, which makes it possible to increase the size of the tubers. The technique allows you to remove 2 kg of potatoes from a bush.
Lavrov's technique. The method, which originated in the Tula region, involves harvesting 3 potato crops from 1 acre, which is ensured by repeated planting of early ripening varieties (late April, early June, early August). Subsequent batches are planted in row spacing 80 cm wide approximately 2 weeks before the planned digging of the first planting. This technique allows 100 kg of planting material to produce 450 kg of yield per 1 sq.m.

As an experiment, you can try each method in practice to find out which one will be the most convenient, least labor-intensive and productive for you.

Selection of productive varieties

To get the maximum yield from an acre allocated for potatoes, you need to choose high-quality seed, focusing on popular and productive varieties. Thus, the most popular among gardeners and professional farmers are:

early Red Scarlet (450-600 kg per hundred square meters);
early Timo (350-600 kg per hundred square meters);
early Zhukovsky (300-600 kg per hundred square meters);
early Bellorosa (320 kg per hundred square meters);
mid-early Nevsky (600 kg per hundred square meters).

Feeding and watering

The yield of potatoes is affected by the regime of watering and fertilizing. As a rule, fertilizers are applied to planting holes and mixed with compost. Good effect on potato yields:

ammonium nitrate, which serves as a source of nitrogen, which is important for the development of green mass;
Superphosphate, the granules of which gradually dissolve and supply the crop with substances important for the formation of tubers;
Super compost, which increases the nutritional value of the soil due to the work of beneficial bacteria.

If you wish, you can also fertilize during the periods of flowering and tuber formation, but at this stage you should select fertilizers without nitrogen. Otherwise, active growth of tops will occur to the detriment of yield.

You will learn clearly about the planting method and the use of fertilizers at this stage from the video:

Many gardeners believe that atmospheric precipitation is enough for potatoes and do not pay due attention to planting. However, regular watering during periods of growth and flowering has a positive effect on crop yield, tuber size and their characteristics.

What is the average consumption per 1 hectare and per 1 hundred square meters for different planting methods?

One of the decisive factors in calculating the potato norm is the planting method: single or double rows. They differ in their nuances.

Single rows

Planting in single rows is the most traditional way to grow potatoes. In this case, the row spacing is from 70 to 90 cm (due to the dimensions of the agricultural machinery), the distance between the holes will be approximately 25–45 cm.

If we take a hundred square meters (100 square meters) for calculation - a conventional plot of 12.5 × 8 m, provided that the distance between the rows is 80 cm, and there are an average of 10 rows in total, and their length is 125 m, we get 1250. Each seed tuber must have at least 5 eyes. Divide 1250 by 5, we get 250 tubers.

For large sown areas, calculations are also carried out. An average of 65 thousand tubers are sown per hectare of area.

If the seeds are 30-50 g , then you will need 2500-2800 kg (2.5-2.8 tons) per hectare (approximately 65-70 thousand tubers).
If the weight is 50-80 g , the consumption will be 3000-4500 kg (3-4.5 tons) per hectare (on average 55-60 thousand tubers).

Double rows

There are several techniques for planting in double rows. But in any case, the width of the double beds is approximately 40-45 cm, and the distance from bed to bed is 90-110 cm, between bushes - approximately 30 cm. To determine the consumption of seed in this case, add up the width of the bed and the distance between the beds, and divide the length of the section by the resulting number.

Provided that the width of the bed is 45 cm, and the distance between the beds is 90 cm, and 7 beds will fit on 1 acre (74 per hectare). On a 10-meter double row you can plant 66 bushes.

This means that for 1 hundred square meters you will need 462 tubers - approximately 367 kilograms.
Per hectare - 49,284 potatoes, which is equal to 3.9 tons of seeds.

Growing technology

To collect not only the first, but also the second harvest of the crop, you will have to follow the recommendations:

Regular watering procedures will help to grow potatoes correctly. The crop is actively watered during the growing season, when tubers are formed, then the number of procedures is reduced.
Vegetables are planted in a sunny place; they grow poorly in the shade of trees. Gardeners prefer flat surfaces that are well lit by the sun.
To harvest two crops in a season, you will have to feed the plant; humus and cow manure are used as fertilizers. Potatoes are fed when planting, the procedures are repeated after 10 days, then fertilizers are used when the crop begins to bloom.
You will have to treat the planting and eliminate pests; for this purpose, various solutions (insecticides) are used.

If a summer resident lives in Siberia, then he will only be able to harvest several potato crops if he cultivates them in greenhouse conditions. Preference is given to early and mid-ripening varieties.

When the climatic conditions in the region can hardly be called favorable, you will have to:

Choose a potato variety based on the climate.
Plant crops in a timely manner, having previously chosen a location.
Fertilize the soil, monitor the quality indicators of the soil.

Description and characteristics of the Red Scarlet potato variety, planting and care

Read

It is advisable to use green manure, they will help the soil to “rest”. The land is sown with green manure after harvesting. When the crop grows, it is mowed and then the soil is dug up. The procedure can be repeated in the spring.

Basic information about the culture

Potatoes are a versatile vegetable. Tubers are one of the most popular food products; they are used in folk medicine and for cosmetic purposes. Many dishes are prepared from them. Potatoes are processed into starch, potato flour, and molasses. Alcohol is obtained from it. Potato juice treats gastritis and has a beneficial effect on the digestive system.

The potato bush consists of several leafy stems. Plant height is from 30 to 160 cm, depending on the variety. The average number of stems is 6-11. Leaves are dissected and wrinkled. The color of the stems and leaves is green. Flowering begins 25-35 days after planting. Lasts 5-8 days. Flowers are white, purple, golden, pinkish. They are located at the very tops of the stems. The petals grow together. There are varieties with flowers and without flowers. After the potatoes have flowered, green berries appear on them. They are poisonous.

Additional Information. Vitamin C, present in tubers, improves immunity and protects the body from the negative effects of the environment. Nourishing vegetable masks refresh the skin, whiten it, and eliminate fine wrinkles.

During flowering, tubers form on the underground part of the plant. They grow not on roots, but on stolons. Stolons are shoots that develop from buds on the underground part of the stems. Tubers form on the stolons. The tubers themselves are thickened and short stems. They have eyes that contain buds. New stems can grow from the buds.

The tubers are covered with a corky elastic skin. It protects potatoes from drying out, impacts, and pests. Next comes a layer of cells where there is the most starch. Then the pulp begins. Tubers can have brick, yellow, white, or purple skin. This characteristic depends on the variety.

Potatoes reproduce vegetatively. Gardeners use whole tubers or parts with eyes for planting. Stems sprout from the buds and form potato bushes. Tuber germination occurs at temperatures from +8 degrees. Therefore, it is recommended to plant potatoes in May.

A bucket of potatoes from one bush is real

To collect a bucket of potatoes from a bush, it is important to properly and constantly care for it.

If you want to get the maximum yield, you should plant potatoes a little less often than usual, this will increase the feeding area of one plant.

Even during planting, you should add half a bucket of humus to one hole , then add 1-2 tablespoons of wood ash, mix right in the hole, put the sprouted tuber, bury it and cover it with hay. Regular watering is important - once every four days. If you are chasing the harvest, you should not miss it.

To obtain a high potato yield, when planting, seed material should be fed with humus and ash.

As soon as the tops wither, mow them and leave the potatoes for two weeks, allowing them to dry out . Then we dig up the potatoes and get a good result.

for both a beginner and a gardener with extensive experience to learn some features of caring for potatoes , since new varieties appear from year to year and climatic conditions change. If you follow the tips, you will get the desired result.

When selecting seed tubers from the fall harvest or when purchasing them, it is important to determine in advance how much planting material will be needed. This value depends on many factors: potato varieties, tuber size, soil fertility, climate in the region, growth path.

How to increase your harvest

The most pressing question among all gardeners is how to increase the yield. Let's look at the basic principles of increasing it.

Selection of planting material

One of the first and basic principles is the selection of planting material. It is worth taking a responsible approach to the matter - your harvest directly depends on it.

The first rule of seed selection is that tubers of sick and weak plants are not left for propagation.

Potatoes are selected for seeds during harvest. If you dug up a bush and all the vegetables are approximately equal, you can safely put them aside for planting, there’s nothing wrong with that, it’s much more difficult to select from the general heap

It is very important not to mix varieties under any circumstances.

Powerful plants are noticeable during flowering; it is worth highlighting them with an identification mark. Then select potatoes from the marked areas. If the tubers are laid from one bush, all of about the same size, smooth and even - in the future, they will produce a better harvest, due to strong genes.

Calculation of the volume of planting material

Using the formula presented above, you can easily determine the amount of sowing potatoes you need. But, you are unlikely to be able to calculate by the weight of the vegetable how much harvest you will get, since this is fully influenced by growing conditions, soil fertilization and proper care.

Planting density

Planting density and planting rate are determined by the potato variety, the properties of the seed tubers and the weather.

It would seem that the denser we plant, the more we will collect, but no. In fact, if you plant too often, the feeding area of one plant will decrease, which will lead to fewer tubers.

But if the feeding area is 70*20 cm, the harvest will be decent.

When to plant?

The time for planting potatoes directly depends on the region. In the southern regions, planting is carried out at the end of March - beginning of April; the further you go north, the later the earth warms up and sowing occurs.

When planting potatoes in unheated soil, there is a high probability of tubers freezing and, as a result, slow germination and development.

Increased yield

Due to genetic characteristics, some varieties can form up to 16 tubers, while others only 7-10, but do not forget about the importance of fertilizers. Any potato needs complementary feeding during the period of tuber formation. Below are some effective ways to increase potato yield

Below are some effective ways to increase potato yield.

Bark

Rotted bark

To use bark as fertilizer, it must be rotten, because the process of its decomposition in the ground can take a long time. With the help of bark, you can not only fertilize potatoes, but also protect them from pests, for example, by mixing bark, ash and compost in equal proportions.

Ash

Wood ash is a natural fertilizer
Ash is an excellent potassium fertilizer; in addition to potassium, it contains phosphorus, calcium, magnesium and a large set of microelements. It is suitable for plants sensitive to chlorine, because it lacks this element. It also loosens the soil and changes its structure, in addition, it can be used to deoxidize the soil on the site. If you use ash as a top dressing, you will need only 150-300 grams per square meter. Bring it dry into the holes when planting.

Onion peel

The benefit of onion peel is that it contains a large amount of minerals.

Onion peels will not only serve as an excellent fertilizer, but will also protect your plants from wireworms and other soil pests. It should be placed in the hole before putting in the potatoes. The husks should come exclusively from healthy bulbs to avoid infections and fungi. You can also steep the onion peel in water for three days, then dilute it with 10 liters of water and water it.

Stimulating incision

Making cuts on potato tubers to stimulate growth and produce a rich harvest

Another well-known method is a stimulating incision. This is a longitudinal cut of the tuber with a sterile knife to avoid infection and further decay. This method will speed up germination and also help the plants to grow stronger before the Colorado potato beetle appears.

Distance between tubers

Description of the potato variety Zhuravinka, cultivation and yield
If we figured out the distance between the rows in the previous paragraph, then the question of the optimal distance between the tubers remains open.

Most often in the literature you can find the statement that about 6 bushes should be planted per square meter. If you take exactly this number of plants, then in the case of a row spacing of about 70 cm, it is necessary to maintain a distance between bushes of 26 cm. In practice, in order not to run around with a ruler, this distance practically corresponds to a segment one and a half times the width of an ordinary shovel. You should be guided by the diameter of the hole dug with such a shovel (approximately 25-27 cm).

But when using this planting scheme, the potatoes will grow quite densely. This option is not very profitable in terms of plantation yield. In practice, this scheme is used quite rarely.

More often you can find plantings where the gaps between the bushes will be twice as large. You can also find the following method for calculating the correct distance between bushes. Here the total weight of the potatoes must be divided by the entire area where you plan to plant them. In this case, the resulting figures will be a real reflection of the yield. You can even find data when the distance between the holes is one meter (for a row proximity of 70 cm). But this method gives the lowest yield.

It should be noted that, as in the situation with the distance between rows, it is necessary to take into account the plant variety:

early varieties are best planted at a distance between bushes of 25 to 30 cm;
Late varieties need to be planted at a greater distance - from 30 to 35 cm.

These figures are indicated for tubers that have a standard size for planting (about the size of a chicken egg). When using smaller tubers, the above distances must be reduced. The optimal distance would be about 18-20 cm. For very large tubers, the distance can increase significantly and even be 45 cm.

The distance that is maintained for the rows is not particularly important when choosing the distance between the bushes. This parameter is directly dependent on the characteristics of the soil composition. If the soil is fertile and contains a lot of nutrients, then planting should be done more densely, since the soil’s capabilities will allow the bushes to form normally and produce a harvest of excellent taste and volume. If soil fertility is low, gardeners recommend planting tubers at a greater distance from each other so that in the future the bushes have enough opportunity to produce a crop.

Common potato planting scheme

Tubers are planted in holes. The correct depth for them is from 7 to 10 cm. At this depth, the potatoes will warm up best and germinate quickly. Sprouted stems should be covered with soil on top. This procedure will need to be repeated in a week. This will allow the formation of strong stems, which will have a positive effect on yield. If the planting date was later, then the depth of the hole increases by 3 cm (this rule especially applies to dry periods).

Also, the depth of the hole depends on the type of soil. For heavy soil, this parameter should be about 8 cm. In light soils, the depth of the hole should be about 10 cm. And for clay soils, the hole is made with a depth of 5 cm.

When choosing the depth, you should not strictly focus on the above figures, since you need to make an assessment of the size of the tubers themselves. Smaller potatoes need to be planted at a shallow depth, but for larger ones the depth should be greater. Deviation from the established figures is allowed no more than 3 cm in any direction.

It is recommended to plant tubers in holes with sprouts down. This must be done in order to form better spreading, which will contribute to greater ventilation and illumination of the resulting bush. After this procedure has been completed and all the rules have been followed, use a rake to cover the top of the potatoes with soil.

As you can see, such a seemingly ordinary process as planting potatoes can present a certain degree of complexity. Incorrectly planted tubers can significantly reduce the yield of an entire plantation. Therefore, before starting the process itself, you should first familiarize yourself with the nuances that relate to this issue.

Calculation of potato planting rates

The most important thing in planting potatoes is to comply with the early sowing dates. Meeting the deadlines contributes to the formation of a powerful root system and well-developed tops, which will invariably lead to a high yield. Well-developed plants tend to form tubers quickly and reach full maturity.

This is an integral factor in early harvesting with minimal losses that accompany late harvesting

Well-developed plants are characterized by rapid tuber formation and achievement of full maturity. This is an integral factor in early harvesting with minimal losses that accompany late harvesting.

I would never have thought that in order to get the best harvest on my plot in my entire “dacha career”, I just need to stop working on the beds and trust nature. For as long as I can remember, I spent every summer at the dacha.

First at my parents' house, and then my husband and I bought our own. From early spring to late autumn, all free time was spent on planting, weeding, tying, pruning, watering, harvesting and, finally, preserving and trying to preserve the harvest until next year. And so in a circle...

Calculation of potato seeding rates.

Note: * when sorting potatoes by size, remember that the amount of planting material is directly proportional to the size of the tuber.

Principles for determining planting density photo

When plants planted in a certain area receive sufficient moisture and nutrition, form a powerful root system and leaf cover, and fully utilize solar energy, then this is called the optimal planting density.

When planting potatoes, soil fertility is taken into account. The higher the fertility index, the more potato tubers can be planted on the site. Consequently, due to additional plantings of potato crops, it is possible to obtain a larger yield.

There are standards for optimal planting density per hectare, depending on the region:

Northern and Northwestern regions - from 50 to 55 thousand bushes;
Central and Southern regions - depending on the soil conditions: on sandy loam and sandy soils there are about 45 thousand bushes, on loamy soils up to 55 thousand bushes.

Sowing time

To obtain a decent harvest of corn silage, you should follow the basic rules of planting and caring for the crop.

Sowing should be done exclusively in warm soil. At a depth of 10 cm, the soil should be heated to 12 degrees Celsius. A large harvest of cobs can be obtained by observing the depth of seed placement. On light, loose soils, sow should be sown to a depth of 8 cm, on denser soils (loams, chernozems) - 4-6 cm.

Table of timing of work on areas occupied by crops:

What to do	When to do the work
Preliminary autumn plowing with deep turning of layers	August-October
Harrowing 4 cm of empty soil	April (beginning)
Harrowing 5 cm and removing weeds	April
Pre-sowing seed preparation	May (beginning)
Sowing	May (first ten days)
Loosening the top layer of soil before germination	May (7 days after sowing)
Weed removal and loosening	As you grow up

Some gardeners use herbicides to treat plantings

It is important to remember: medications should be used according to the instructions on the package. Corn is harvested for silage as it ripens (usually in August)

How many potatoes do you need?

How much planting material is needed for a certain area will depend on several conditions:

potato varieties;
tuber fractions;
soil fertility;
regional climate;
growing method.

When planting, use either whole tubers or segments with eyes (rudimentary shoots). In the first case, it is possible to calculate the average consumption of seed material per piece and by weight with a known sowing area. Let's try to figure out what needs to be taken into account and what the calculations depend on.

Per hundred (in kg)

Let's take a conventional square plot of 10x10 meters (one hundred square meters). It can consist of 14 rows, and usually a distance of 60 to 80 cm is left between the rows. As a rule, 30-50 cm are left between the tubers. Thus, 28 potatoes can be planted in a 10-meter row. We multiply 14 by 28, we get 392 tubers per hundred square meters.

Provided that each tuber weighs an average of 90 grams, 35 kilograms of potatoes will be required per hundred square meters.
If the weight of seed tubers is approximately 70–80 g, you need to proceed at a rate of approximately 27–29 kilograms per hundred square meters.
If the weight is less, then the consumption per hundred square meters will be about 25-30 kilograms per hundred square meters.

Important! Those who do not care about exact calculations plant potatoes in the old-fashioned way - at the rate of 3-3.5 buckets per hundred square meters. A ten-liter bucket holds approximately 7 kg of potatoes, so a summer resident will need 3.5-4.5 buckets of potatoes, depending on the size of the tuber.

Per hectare (tons)

For large areas, agronomists use special tables. According to them, approximately 60-65 thousand tubers are planted per hectare. But it is worth taking into account the error in the size of planting material, damage to seeds during storage, and making calculations with a small margin.

The recommended planting quantity is 2000-2500 kilograms, that is, 2-2.5 tons of planting material per hectare with an average tuber with a diameter of 4-6 cm.
For a small tuber of 2.8–3.5 cm, it is recommended to plant 1500–1800 kilograms, that is, 1.5–1.8 tons of potatoes per hectare.
With a weight of 80 grams of each potato, the consumption rate will already be 4800 kilograms per hectare, which is 4.8 tons per hectare.

Does consumption depend on the variety?

Each variety has its own nuances in terms of yield and care. Some varieties are more suitable for harsh conditions, others for milder climates. Usually they are selected depending on climatic conditions, ripening time and purpose.

When calculating planting material, first of all, they are based on the mass of the tuber. And if you select medium seeds, the consumption per hundred square meters will be approximately the same for any variety. But the calculations still depend on the potato variety.

For earlier combs, large tubers of 70–80 g or more are better suited. They will better withstand weather fluctuations and produce stronger shoots.
In regions with milder weather conditions, you can choose tubers 50-70 grams. Among the elite varieties, you can safely select 20-40 gram potatoes.

For planting food varieties, 30 thousand tubers per hectare will be quite enough. To obtain seeds, 2.5-3 tons per hectare are usually planted.

How many potatoes can you harvest from 1 acre?

You can get more than 200 kg (say 4 bags) if you buy elite seeds, monitor each bush more often, feed it. The yield of potatoes largely depends on the condition of the soil and its fertility. In well-fertilized, unpolluted soil, without wireworms and mole crickets, from 1 potato you can dig up 3 to 5 huge potatoes. For example, Zhukovsky early potatoes yield from 100 square meters from 200 to 450 kilograms. The Red Cat potato variety yields from 450 to 600 kilograms per 1 hectare, that is, 100 square meters.

But, nevertheless, not a single variety will survive and every year there will be less harvest if the land does not rest and is not fertilized.

The answer to this question depends on many circumstances and specific factors:

Firstly, from the land on which these potatoes will grow.
Secondly, it depends on the type of potatoes planted.
Thirdly, from the weather conditions and characteristics of the area, even from a height above sea level.

A specific indicator is in the Tambov region, on black soil, Sineglazka, under favorable conditions, produces about two bags, i.e. about 70-80 kilograms.

How many kg do you collect from 1 hundred square meters?

More than 100 kg Less than 100 kg

Calculation for large areas

The rate of planting potatoes for the fields of agricultural enterprises or farms is calculated in a similar way. However, generally accepted measures are used to simplify calculations. There are tables compiled by employees of agricultural enterprises. So, approximately 60,000-65,000 tubers are planted per hectare. If the weight of one tuber is 80 g, then the consumption rate is 4800 kg/ha. If converted to centners, then this is 48 centners per 1 hectare.

Potatoes in fields measured in hectares are planted in rows with a large distance between them (from 70 to 100 cm). This is necessary so that equipment, such as a tractor, can pass through. It is used to plant and harvest crops.
