How many flower seeds in 1 gram. Seeds: determining the amount of seeds needed for sowing

HOW MANY SEEDS ARE IN 1 GRAM

Seeds of vegetable crops differ in size, shape, color. The seeding rate largely depends on the weight of the seeds. Many of our customers ask: how many seeds are in 1 gram? We decided to answer the question in detail. Information about the mass of seeds of various vegetable crops, the temperature of germination and the timing of emergence of seedlings are written in the table below.

The largest seeds are in beans, the largest are beans and peas. The average size is typical for seeds of cabbage, onions, sweet peppers, eggplants, tomatoes, radishes, radishes. Small seeds have carrots, parsley, dill, lettuce.

Seed size must be taken into account when determining the seeding rate. The larger the seeds, the more they will be needed per unit area (and the greater the sowing depth). If we sow beans, peas and beans at a rate of 15-20 grams per 1 m2, then carrots, dill and parsley, lettuce - 1-2 grams per 1 m2. Therefore, it does not make sense to buy one bag of beans or beans - it is better to take 5-10 pieces at once, but one bag of carrots or cabbage is enough.

The table also contains data on the temperature at which seeds begin to germinate. Cold-resistant crops - cabbage, onion, rhubarb, turnip, lettuce, dill - already begin to germinate at 2-3 0C, radish, radish and sorrel - at 1-2 0C. These crops should be planted in early dates. Heat-loving crops - eggplant, cucumbers - germinate at higher temperatures of 13-15 0C, tomato seeds, beans, zucchini - from 10-12 0C. We plant these crops at the onset of good warm weather, or seedlings in advance.

This table contains the timing of the emergence of seedlings. We see that beans, peas, cabbage, radishes, radishes, turnips will sprout the fastest (3-8 days). You will have to wait longer for sprouts in carrots (carrots sprout in 9-15 days), beets (beets sprout in 8-16 days), onions, parsley and celery (celery sprouts in 12-22 days). To speed up the shoots and make them friendly, various tricks are used (soaking in water, etc.).

This table, which we found in Dolgikh's book "Growing Vegetable Seeds on Homestead Plots" (Rosselkhozizdat, 1986), can provide such interesting information.

Edelstein in "Vegetable" suggests the following grouping of seeds of vegetable plants by size:
1. seeds are very large: 1-10 seeds in 1 gram - beans, beans, peas, pumpkin, corn, watermelons.
2. large seeds: a) 10-60 seeds per 1 gram - artichokes, watermelons, melons, cucumbers, beets, asparagus. b) 60-100 seeds in 1 gram - rhubarb, spinach, radish, radish.
3. medium seeds: 150-350 seeds in 1 gram - peppers, cabbage, onions, tomatoes, eggplants, parsnips, rutabagas, turnips.
4. small seeds: 600-900 seeds in 1 gram - turnip, carrot, parsley, dill, chicory.
5. seeds are very small: 1000-2000 seeds per gram - sorrel, celery, potatoes, lettuce, tarragon (5000-6000).

Addition to the table:

I will write the name of the crop, and then the number of seeds in 1 gram:
Artichokes - 15-25
Rutabaga - 300-400
Kohlrabi cabbage - 250-300
Corn - 3-10
Leek - 400
Pasternak - 200
Squash - 5-10
Asparagus - 40-60
Spinach - 90-120
Tarragon - 5 000
Watermelons - 6-30
Melons - 20-30
Pumpkins - 2-5

The size, shape, color of planting material are the main criteria by which seeds of cultivated plants can be characterized. The online store offers high-quality planting material, where each package contains all the necessary information, as well as the weight of the seed material in grams. Reading the information on the packaging, many buyers are wondering how many seeds are in one gram in order to take this moment into account when calculating the seeding rate per square meter. meter or the number of bushes.

Is it important to know how many seeds are in a bag?

The size of garden plots forces owners to carefully plan the planting pattern of cultivated plants, and knowing the number of seeds greatly simplifies this task. Understanding how many pieces of seeds are in a package, you can correctly calculate the number of beds, bushes, site parameters for a particular crop.

How to correctly classify seed material by size?

Plant seeds are a kind of fractional elements of different sizes, so the number of seeds in 1 gram is highly dependent on the size of the planting material. There are special tables of seed mass, taking into account the size:

1. Very large seeds (10 pieces in 1 gram): plants of the Pumpkin and Legume families (beans,.
2. Large (70-100 pieces per 1 g):,.
3. Medium (150-300 pieces per 1 g): onion seeds,.
4. Small seed material (600-1000 pieces per 1 g):, dill, parsley, salad crops,.
5. Very small (over 1000 pieces per 1 g): sorrel, tarragon.

Why is it important to consider the number of seeds when buying?

The size of the planting material significantly affects the calculations during planting, the determination of the seeding rate. Large seeds will need more per unit area than small seeds. For example, when planting very large and large seeds, the seeding rate is 20-50 g/m2, when planting small seeds - 2 g/m2, medium ones up to 10 g/m2, very small ones - 1 g/m2. Planting calculations are indicative and subject to change based on growing conditions and chosen growing method.

Flower seeds differ in shape, size and weight. The sowing rate of seeds largely depends on their mass. After all, the larger the seeds, the more they need per 1 unit of area.

It is difficult to determine their number of seeds, the mass of which is indicated in grams. Another thing is if their number on the package is indicated in pieces. Therefore, it is not superfluous to know information about how many flower seeds are contained in 1 gram.

Based on this table, you can easily calculate the number of seeds depending on the area to be sown.

Some of them are especially large, for example, 1 gram of false calamus iris contains only 20 pieces. Whereas the seeds of some wild flowers are more like dust particles. 1 gram contains about 80,000 centaury seeds. Many wild flowers, by virtue of the fact that they have to survive, are excellent self-sowing, spreading thousands of seeds and filling vast areas.

Seed sizes

In addition to the information given in the table, there is a grouping of plant seeds by size. But this grouping is relevant in relation to vegetable crops. Although you can navigate by it, if we are talking about some flower crops.

Size should not be compared with their weight, which determines their lightness or heaviness. The weight of the seeds of some vegetable and flower crops varies depending on the variety. Largeness is a dimensional concept and a relative one. So, for example, when sorting seeds of the same crop, those that make up the bulk of the batch with a standard set of sieves will be considered average. Seeds that are larger than average are considered large, and those that are smaller than average are considered small.

What is the difference between large and small seeds? Small seeds, although containing fewer nutrients, are easier to spread. They are carried by the wind, so they are more likely to be in an area where it is not so crowded yet and germinate. In addition, small seeds of some plants are able to stay in the ground for a long time, maintaining their germination capacity and germinating when conditions are most favorable.

Large seeds, deprived of the ability to be transported over long distances, carry a larger supply of nutrients, due to which they find the strength to take root where the proximity of plants is too dense. But the plant is unable to produce a large number of large seeds, most of them quickly lose their germination. They need more to sow a certain area.

Vegetable grains differ in shape, size, weight and color.

The largest seed beans, beans and peas.

The average size in tomatoes, cabbage, peppers, eggplant, onions, radishes and radishes.

small size characteristic of carrots, dill, parsley and lettuce.

The sowing rate depends on the weight of the grains. The period and temperature conditions of seed germination are also of great importance.

Seed packaging

• Seeds from 0.3 to 10 grams - sowing material for amateur gardeners cultivating a summer cottage or a small personal plot.
• Seeds of 100 and 500 grams are seed material for gardeners who grow vegetables for business or a specific group of crops.
• Seeds by weight - seed material for gardeners with a plot of more than 30 acres and engaged in the cultivation of vegetables of a particular type for business.
• Seeds in bulk - seed material for farmers who have a plot of more than 1 hectare and are engaged in growing vegetables at a professional level.
• Seeds on a tape - sowing material for summer residents and gardeners, facilitating work and contributing to the appearance of uniform seedlings;
• Dutch seeds are seed material of foreign selection, which makes it possible to grow unique varieties of vegetables (in a package from several seeds to several grams).

The formula for calculating the number of seeds for sowing

To determine how many packs you need to buy, you must consider the following parameters:
(NG/M²) - Norm g/m²
(PP) - Planted area
(Qty G) is the number of grams
Based on this, the calculation formula is as follows: NG / M²xPP \u003d Q-vog

Calculation example

You need to calculate how many cucumbers you need to buy in order to plant 6 m². The consumption rate of cucumber grains is 0.16 g per m² (we take the average value). We multiply NG / M² (0.16) by ZHPP (6m²) and we get the required number of grams - 0.96 g. Packing of cucumbers varies from 0.2 g to 5 g and more (100 g). Varietal and hybrid cucumbers are sold by the piece, in a pack there can be from 10 to 50 pieces. To find out how many grains are in 0.2 g, divide the approximate number in 1 gram by 5 (200 mg is the 5th part of 1000 mg). Thus, in a pack of 0.2 g there are about 8 grains. In a pack of 0.5 g there will be about 20 grains. Next, you need to take into account the next parameter - the method of growing cucumbers. These crops can be grown in open field without a garter or in a greenhouse (in pots, for example), with a vertical garter. When grown in open ground, from 2 to 3 bushes can freely grow and develop per 1 m², depending on the variety and size of the shoots. When grown in a greenhouse with a vertical garter per 1 m², from 4 to 6 bushes can be planted without damage to the plant.

Therefore, when determining the required number of grains for sowing, please pay attention to all parameters, and the number of seeds in a pack, and their weight.

I hope the information above is helpful to you.
