The grain industry in Ukraine is the most important component of the agro-industrial complex. At the same time, spring wheat grain production remains low and unstable due to insufficient efficiency of cultivation technology. The purpose of the research was to establish optimal seeding rates for soft spring wheat (Triticum aestivum L.) seeds of the Shirocco variety. The study of the influence of the seeding rate on the productivity and quality indicators of soft spring wheat was carried out according to the scheme: 3.5 million pcs ha-1, 4.0 million pcs ha-1, 4.5 million pcs ha-1, 5.0 million pcs ha-1; 5.5 million pcs ha-1; 6.0 million pcs ha-1. As a result of the research, it was found that the highest density of standing was obtained on the variant with a seeding rate of 6.0 million pcs ha-1 - 522 pcs m2 with plant preservation during the growing season of 86.8% (453.1 pcs m2). The maximum yield was observed on the variant with a seeding rate of 6.0 million pcs ha-1 - 5.63 t ha-1. At a seeding rate of 3.5, 4.0, 4.5, 5.0, 5.5 pcs m2 the yield was 4.07, 4.58, 4.76, 5.00, 5.30 t ha-1, respectively. According to the results of the research, it was studied that at a seeding rate of 6.0 million pcs ha-1, the highest yield of spring wheat grain was obtained - 5.63 t ha-1, and the maximum quality indicators of gluten and protein content at a seeding rate of 5.5 million pcs ha-1 - 25.5, 13.82%, respectively.
