What is the seeding rate of wheat per 1 ha? In order for wheat to grow well and have a bountiful harvest during harvest, the necessary area is needed, a large amount of vitamins important for nutrition in the endosperm. With the required area, plants can take all the necessary nutrients and moisture from the soil, thereby creating the necessary vegetative mass and forming grains. If the crop is thickened or sparse, then the amount of the crop is significantly reduced.

Thick seeding

When sowing thickened, due to the fact that the plants do not receive enough light at the 1Y-Y stage of organogenesis, most of the existing shoots immediately die off and become unsuitable for further growth processes, so you need to observe the seeding rate of wheat by 1 ha. Otherwise, the agronomist will not get the proper result.

The surviving plants continue to grow, but at the same time it slows down,the formation of puny grain occurs, all this contributes to a small amount of the harvested as a result. In the case of dense sowing, wheat also germinates poorly, becomes less frost-resistant, more susceptible to all kinds of diseases, damage by harmful insects, and the risk of lodging increases. Due to non-compliance with the uniform distribution of sowing, the formation of unequal sowing density occurs. The planted wheat turns out in some places sparse, in others thickened. The uniform standing of wheat depends entirely on the amount of seeding. The higher it is, the worse the correct distribution of crops. This favors a poor harvest, a decrease in crop productivity, and its life cycle is at great risk. An increase in the sowing rate of wheat by one hectare, which is not justified by the sowing campaign, leads to a significant decrease in the expected rate of the resulting crop.

Sparse seeding

In this case, the potential productivity decreases due to the fact that a large area is not fully used, unsown gaps remain, if the seeding rate of wheat per 1 ha is not observed, they become clogged. Due to the large area of infestation, wheat does not receive a complete set of essential minerals and vitamins. Sparse sowing becomes the reason that plants receive less than the norm of liquid, vitamins, the amount of adjustment and sagging increases greatly, so the grain is formed defectively.

Winter wheat produces a large amount of crop if the seeding rate has not been violated. The value of the norm depends entirely on the weather conditions of a certain area, on the soil, the predecessor of wheat, the fertilizers used, the specific individuality of any variety, the time of sowing, the sowing method and the quality of all seeds used are also taken into account.

With fertile soil, beneficial crops that grew on the territory before wheat, and high-quality fertilizers, the amount of wheat for sowing per 1 ha is necessarily reduced. Varieties that have a high level of bushiness are planted, reducing the norms in comparison with weakly bushy ones. According to experts, the seeding rate of the crop should increase in those areas where there is sufficient moisture in the fields. The pre-examined soil also leads to several conclusions. With poor soil and low germination, the rate definitely becomes larger, the soil of chernozems suggests good germination, so the rate is reduced several times intentionally.

Wheat sowing dates

The sowing rate depends on the sowing time. Early sowing of wheat means good formation and clustering, due to which the amount of wheat to be sown is reduced. Late sowing means more time for the normal formation of good stems, so the seeding rate for the sowing campaign is increased by 14%.

Some statistics: wheat seeding rate per 1 ha

These statistics were collected thanks to the checks and observations of specialists. 2-3 cm is the recommended sowing depth, and the rate for most varieties is up to 4-5 million viable seeds per 1 hectare(160-250 kg). In the first few years with the development of new technologies, it was necessary to adhere to the requirement that per 1 sq. m should be present up to 600 he althy and resistant stems, while the density of sowing can be adjusted by increasing the rate. This requirement led to the fact that people began to sow 5-6 million / ha. But such norms do not promise a plentiful and he althy harvest, some of the stems die, growth decreases.

The yield and growth process with a small amount of planted product can be explained by the fact that intraspecific struggle and lodging become smaller, and the size of the roots, the level of germination and resistance increases. Each plant, each stem develops individually.

Closing word from experts

When reducing the amount of planted wheat, you must follow all the rules, because their non-compliance may lead to a rarefaction of sowing (when the seeding rate of wheat per 1 hectare is below 0.3 million). Experts determine the right amount of wheat for sowing according to a special formula that prevents rarefaction and thickening. The rate is determined by the technology formulas used by the sowing campaign.
