THE INFLUENCE OF SMOKING PROCEDURE, FERTILIZER RATE AND THICKNESS OF GAZA NEWLARIN ON THE WEIGHT OF A PIECE OF COTTON SHORTS
Abstract
In the article, in the conditions of medium salinity, grazing light gray soils of the Syrdarya region, if we calculate the amount of water used in the 70-70-65% irrigation system compared to the 75-75-65% irrigation system in comparison with ChDNS, then in the 70-70-65% irrigation system Compared to the 75-75-65% irrigation method, it was found that the amount of seasonal water consumption was 329.0-349.8 m3/ha. It should be noted that due to the fact that the groundwater level is located on the surface, the soil moisture is well preserved, taking into account that the seasonal irrigation rate was not too high, on average, 336.7 m3/ha of water was saved in three years.
Soil moisture before irrigation is in the order of 70-70-65% compared to ChDNS, the rate of fertilizers is N220, P154, K110 kg/ha, seedling thickness is 100-110 thousand bushels/ha in Sultan cotton variety 33.1 ts/ha in S-6524 cotton variety 32.2 ts/ha, soil moisture before irrigation is in the order of 75-75-65% according to ChDNS, the rate of mineral fertilizers is N220P154K110 kg/ha and when we increase the thickness of seedlings to 100-110 thousand bush/ha, it is 35.4 ts/ha in Sultan cotton variety, S -Increased to 34.4 ts/ha in cotton variety 6524.
Keywords
In the article, the medium salinity of the Syrdarya region, light colored gray soils of the Syrdarya region, and the new, regionalized and promising Sultan, S-6524 cotton varieties were taken.
