What is the sowing rate of wheat per 1 ha? In order for the wheat to grow well and a plentiful harvest was present during the harvest, the required area, a large number of vitamins important for nutrition in the endosperm are needed. With the required area, plants can take from the soil all the necessary nutrients, moisture, due to this create the desired vegetative mass and form grains. If the sowing is thickened or sparse, then the amount of yield obtained is significantly reduced.
Thickened sowing
With thickened sowing, due to the fact that the plants do not receive enough light at the 1U-U stage of organogenesis, most of the existing shoots die off immediately and become unsuitable for further growth processes, therefore, it is necessary to observe the sowing rate of wheat per 1 ha. Otherwise, the agronomist will not get the proper result.
The surviving plants continue their growth, but at the same time it slows down, the formation of punctured grain takes place, all this contributes to a small amount of the harvested as a result. In the case of thickened sowing, wheat also sprouts poorly, becomes less frost-resistant, more susceptible to all kinds of diseases, damaged by harmful insects, and the risk of lodging increases. Due to non-compliance with the uniform distribution of sowing, the formation of unequal density of standing of the sowing occurs. Planted wheat is obtained in some places sparse, in others thickened. The uniform standing of wheat depends entirely on the seeding volume. The higher it is, the worse the correct distribution of the crop. This is conducive to a poor harvest, reduced productivity of sowing, its life cycle is at great risk. An increase in the sowing norm of wheat per hectare, unjustified by the sowing campaign, leads to a significant decrease in the expected norm of the resulting crop.
Sparse seeding
In this case, the potential productivity decreases due to the fact that a large area is not fully utilized, there are non-sown intervals, if the seed rate per 1 ha is not respected, they become clogged. Due to the large area of weediness, 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 fluid, vitamins, the amount of planting and sowing increases significantly, so the grain is formed defectively.
Winter wheat gives a large amount of yield if the seeding rate has not been violated. The value of the norm depends entirely on the weather conditions of a particular area, on the soil, wheat precursor, fertilizers used, and the specific personality of a particular variety, sowing time, sowing method and the quality of all seeds used are also taken into account.
With fertile soil, beneficial crops that grew in the area 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 rates in comparison with weakly bushy. According to experts, the sowing rate of the crop should increase in those areas where there is sufficient moisture in the fields. Soil examined in advance also leads to several conclusions. With poor soil and low germination, the norm definitely becomes larger, the soil of chernozems suggests good germination, so the norm decreases by several times intentionally.
Wheat sowing dates
The sowing rate of products depends on the timing of sowing. Early sowing of wheat implies good formation and grouping, due to this, the amount of wheat for sowing is reduced. Late sowing implies a longer time for the normal formation of good stems, therefore, the sowing rate for the sowing campaign is increased by 14%.
Some statistics: the sowing rate of wheat per 1 ha
These statistics were collected due to inspections and observations of specialists. 2-3 cm is the recommended seeding depth, and the norm in this case is up to 4-5 million germinating grains per hectare (160-250 kg) for most varieties. In the first few years with the development of new technologies, it was necessary to adhere to the requirement of 1 sq. Km. m should be present up to 600 healthy and persistent stems, while the density of sowing can be adjusted by increasing the norm. This requirement led to the fact that people began to sow 5-6 million / ha. But such norms do not promise a plentiful and healthy harvest, part of the stems die, growth decreases.
The number of crops and the 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 individually develops.
Closing remarks by specialists
Reducing the number of planted wheat, you must follow all the rules, because their non-compliance may lead to rarefaction of sowing (when the rate of sowing of wheat per 1 ha is lower than 0.3 million). Experts determine the right amount of wheat for sowing according to a special formula that prevents dilution and thickening. The rate is determined by the technology formulas used by the sowing campaign.
