The article provides data on the study of the influence of the timing of the introduction of mineral fertilizers on the technological indicators of soft wheat grain in the arid climate of the Republic of Karakalpakstan. According to the research results, the positive effect of fractional application of nitrogen fertilizers on the improvement of technological parameters of grain in comparison with a one-time, pre-sowing application was noted. The varieties that, under these conditions, formed the best technological indicators corresponding to a high group of grain quality, were noted.
