Abstract

In the article, the growth, development, grain yield and quality of winter wheat in the conditions of the typical gray soils subjected to irrigation erosion of Samarkand region (Uzbekistan) are evaluated using resource-efficient agro technologies (softening along the length of the experimental field and contour method of soil tillage at a depth of 25-28, 32.35 cm) and mineral fertilizer standards. (N240P168K120, N200P140K100, N100P70K50 kg/ha) effects were studied in 2017-2019. Under these conditions, when growing winter wheat, applying mineral fertilizers N200P140K100 in unwashed areas, N240P168K120 when the soil is heavily washed, in moderate stratification and plowing in the contour method at a depth of 32-35 cm, allows for the recovery of winter wheat seeds at a high level (90.5; 89.7%), as well as the general plant and having a positive effect on the number of productive stems, 490.3, 536.3 and 415.7 and 483.2 units/m2 in areas with unwashed soil, and 466.4-519.5 and 403.2-466.3 units/m2 when strongly washed m2 and a positive correlation (r=0.83) between the productive cluster and the number of clusters, the length of the spike is 9.7-10.0 cm, the grains in the spike are 49.0-49.9 grains, and the mass of one spike and 1000 grains is 1.45-1.51 and 42.0-43.3 g to be the highest, respectively, 61.6-60.5 t/ha of grain production and a positive correlation between the grain yield between the main soil tillage methods and depths (r = 0 ,94) ensuring the dependence, in all parts of the field (unwashed soil and strongly washed) grain quality is high (protein 14.3-15.6; gluten 29.7-33.1; vitreous 49.9-51.5%; the grain type is 765-784 g/l and the total baking value of the flour is 3.7-4.1 points) information on the cultivation of grain crops is given.
