THE EFFECT OF DIFFERENT SOWING PERIODS AND FERTILIZER RATES ON THE GRAIN QUALITY OF WINTER SOFT WHEAT VARIETIES

Abstract

This article examines the relationship between sowing rates, sowing periods,
and the amount of mineral fertilizers with the grain quality indicators of the winter
soft wheat varieties Yaksart, Ghozg’on, Bunyodkor, and Krasnodarskaya-99 under
the irrigated light gray soil conditions of the Kashkadarya region. According to the
results of the experiments, it was observed that as the sowing period was delayed
and the seeding rate increased, the amount of protein and gluten in the grain
gradually decreased. Conversely, an increase in fertilizer rates led to an
improvement in grain quality.
