Abstract: The article discusses the issues of formation of crop density and structure of spring wheat crop, depending on the varietal characteristics of gray forest soils in the Republic of Mari-El. The varieties Simbirtsit, Amir and Ekada-109 were studied. The paper displays the results of the analysis of seeds germination formimg, the preservation of plants and elements of the structure of the crop.

The results of two-year experimental data on the growth, development and productivity of spring durum wheat cultivars - Bezenchukskaya Niva and Bezenchukskaya Zolotistaya - in the Chuvash Republic were considered. It was found that decrease in the seeding rate of germinating seeds (from 7 to 3 million per 1 ha) resulted in reducing of the growing period in the studied cultivars of spring durum wheat by 6-7 days. Seeding rate of 5 million seeds per 1 ha provided the maximum density of spike-bearing stems due to the best indicators of general and productive tillering. The formation of the largest main spike with a high grain content in Bezenchukskaya Niva cultivar was noted at the seeding rate from 3 to 5 million seeds per 1 ha. Increase in the seeding rate ( 5 million seeds) led to a decrease in the parameters of the main spike. Analysis of Bezenchukskaya Zolotistaya yield structure did not reveal clear patterns in the change in length and grain size of the main spike resulted from the seeding rate. However, the highest 1000-seed weight (50.4 g) was obtained in the variant with a seeding rate of 6 million seeds pieces. Compared to the control, the maximum yield increase in cv. Bezenchukskaya Niva (1.2 t/ha) was obtained in the variant with a seeding rate of 5 million seeds per 1 ha. The highest yield of cv. Bezenchukskaya Zolotistaya (3.23 t/ha) was obtained at a seeding rate of 6 million seeds per 1 ha.
