Components of grain corn yield

BIOLOGICAL COMPONENTS OF CORN YIELD:

GERMINATION

  • Soil temperature is not less than 10 o C
  • The soil should be light and moist around the kernel
  • It takes 12 - 17 days before emergence

THE PERIOD OF VEGETATION

  • Active development of the root system
  • Sensitivity to low temperatures
  • Sensitivity to phosphorus deficiency
  • Formation of the final sowing density
  • At the stage of 10 leaves, it is especially in need of moisture and nutrients

PANICLE EMERGENCE AND FLOWERING

  • Sensitive to nitrogen and moisture deficiency
  • Stage of cob formation
  • Sensitivity to high temperatures (40 ° C)
  • Formation of the number of grains (25 days after flowering)

RIPENESS

  • Physiological maturity is reached when the humidity is 40%.
  • The accumulation of assimilants is completed
  • Appearance of a black dot: the grain is no longer dependent on the cob

AGROTECHNICAL COMPONENTS OF GRAIN CORN YIELD:

SOWING

  • Sowing with conditioned seeds
  • Light, well aerated soil with sufficient moisture
  • Sowing depth of 5-6 cm
  • Sowing at a speed of 5-7 km/h with a precision seeder;
  • Controlling the depth and uniformity of sowing.
  • Adjust the sowing density

CROP CARE

  • Application of soil herbicides after sowing
  • Fertilizing with microelements in the phase of 4-6 leaves
  • Application of insurance herbicides in the 3-5 leaf stage
  • Meeting the nitrogen requirement at the stage from 10 leaves to flowering
  • Treatment with potash fertilizers to increase drought resistance
  • Pest and disease control before flowering

HARVESTING OF THE CROP

  • Harvesting with threshing of heads of cabbage at a moisture content of not more than 25-30%.
  • Harvest in a short time (10-15 days)
  • Delayed harvesting and delayed harvesting leads to crop losses
