PRODUCTIVITY OF DIFFERENT RICE VARIETIES DEPENDING ON THE TERMS OF FALL POWING
Optimum plant density is one of the important factors in the formation of highly productive crops. On average, over three years of research with different varieties of rice in the “October plowing” variant, it was 378-390 for seedlings, before harvesting - 358-365 pcs / m2, in November -, during plowing in December - 386-397 and 375 -385 pieces/m2, respectively. The highest standing density was noted in the "november plowing" variant - 394-406 and 381-393 pieces/m2. At the same time, a high grain yield was also formed, varying by varieties in the range of 6.87-8.29 t/ha. According to this indicator, the varieties Yubilei and Sarazm were distinguished. The smallest yield (6.24-7.23 t/ha) in all years of research was obtained in the variant "October plowing". When plowing in December, the yield turned out to be closer to the November period, but compared to October, it was much higher
