Wheat sowing rate per 1 ha in kg: seeding depth and what factors influence
Anonim

The yield of cereals is influenced by many factors: the type of soil, the presence of minerals, the degree of soil moisture, the crop variety. You also need to take into account the density of sowing seeds, which is indicated in pieces of grains per unit area. Although in practice most often the seeding rate of wheat is calculated per 1 ha per kg. Manufacturers most often indicate the recommended rate in seed certificates.

Consumption rate of wheat seeds per 1 hectare

For full growth and development, each plant needs a certain area of land. When sowing fields with wheat, it must be taken into account that the yield decreases both with dense growth of stems and with sparse growth.

Thick seeding

A similar situation occurs when the recommended seeding rate for cereals is exceeded. Cons of overseeding:

  • the level of illumination of plants decreases, which leads to the death of shoots;
  • increased risk of disease and insect pests;
  • plants do not harden, they stretch strongly;
  • stems lack nutrition.

The norms of seed consumption, which it is desirable to adhere to by region, are: 120-155 kg/ha in the southeastern regions, 160-175 kg/ha in the Central Black Earth Zone, 200-145 kg in the Non-Black Earth Region.

Sparse seeding

Rare sowing of cereals also contributes to the reduction in yield. Inadequate use of the area directly reduces the yield.Also, weeds quickly sprout on empty land, which leads to a decrease in soil fertility, wheat crops receive less nutrition and moisture. Because of this, defective grains are formed in the ears.

To prevent sparse sowing, you need to know the approximate seed sowing rates for a particular zone. To make it easier to calculate the rate of grain in kilograms, and not in units of seeds, it is taken as a basis that 1000 grains weigh 50 g.

Factors affecting it

When determining the seeding rate, several parameters are taken into account: seed germination, plant variety bushiness, sowing methods, seed loss during wintering (in the case of winter varieties), moisture content in the soil and its fertility, seasonal precipitation forecast. The seeding rate of wheat varies by region. For the northern regions, this figure is higher than for the southern ones.

The quality of the seed must also be taken into account. Initially, when drawing up the standards, 100% germination is assumed. But, as practice shows, the sowing suitability of grain is not ideal, therefore 94-96% germinate.

Sowing depth

Seeds use a lot of energy to germinate, and planting depth has a significant impact on germination rate. When determining this parameter, it is necessary to take into account the quality of the soil. On light, quickly drying soils, it is advisable to plant the seeds deeper than on clay soils or loam.

For the northern regions, a shallow placement of seed (3-3.5 cm) is recommended, wheat is sown deeper in the regions of the Chernozem zone (4-6 cm). In the arid southern regions, the grain is sown even deeper (6-8 cm).

It is also desirable to control the uniformity of sowing in one area. Since, with uneven depth, the seeds germinate unevenly, which affects the quality of the crop.

The sowing work of each crop has nuances. When growing wheat, it is necessary to take into account not only the factors affecting the yield. It is important to take into account the area of the site and choose the right grain seeding rate.
