Effects Of Planting Norm And Feeding Conditions On Growth, Development And Yield Of Soybean Varieties On Typical Burrow Soils Exposed To Irrigation Erosion

In order to produce a uniformly high and high-quality crop from soybeans grown in the conditions of typical burlap soils exposed to irrigation erosion of Samarkand region: in the unwashed part of the soil of the area, the sowing is carried out in the norms of 80 kg/ha seedva N90P63K45 kg/ha, as a result of stratification on the basis of resurstejamkor agrotechnologies in the norms of seedva N90P42K30 kg/ha to n120p84k60 kg/ha when the soil is washed and seedva n70p42k30 kg/ha in the washed soil collected part of the field, the yield of soybeans "Selekta 201" in the areas where the soil is not washed 29,8-31,6-28,3 ts, Variety 26,4-28,5-24,7; sort of "Nena" 24,6-26,2-23,2 ts/ha, these indicators are in accordance with the above-mentioned norms of planting and fertilization in the "Selekta 201" variety in the areas where the soil is washed 28,2-27,5-29,4; on"Uzbekskaya-2" 25,3-24,6-26,2; In "Nena"22,5-21,7-24,8 ts/ha, the yield of the "Selecta 201" variety of soybeans in the above planting and fertilization norms in the collected (accumulated) part of the washed soil of the experimental field 31,5-30,2-29,3 TS / ha "Uzbekskaya-2" Variety 27,8-26,2-24,6; in "Nena"25,6-23,4-22,5 it was determined that ts/ha increased the fertility of these soils and ensured the cultivation of clean products without harming the ecological environment, while keeping the crop and the soil from washing with irrigation water.
