The article presents the results of research on the reaction of soybean plants depending on the timing of sowing in the foothill zone of the Republic of North Ossetia-Alania. The need to improve the timing of sowing occurs with the introduction of new varieties of various ripeness in the main and intermediate crops. The purpose of the paper is to study the effect of sowing dates on the yield of soybean seeds in the conditions of the foothill zone of the RNO-Alania. The scientific novelty was to establish optimal sowing dates that would ensure optimal plant growth and development and high productivity. Our research was carried out in the experimental fields of the North Caucasian Research Institute of Mountain and Piedmont Agriculture of the VSC RAS in 2018-2021. The object of research was the varieties of breeding of the Federal scientific center "V.S. Pustovoit All-Russian Research Institute of Oil Crops. Two main types of soils prevail in the foothill zone: chernozems of varying degrees of leaching, as well as meadow and meadow-boggy soils. The arable layer contains from 3 to 4.4% humus. Down the profile, the amount of humus decreases gradually. The reaction of the soil solution in the upper horizons is neutral, in horizons deeper than 80-90 cm – slightly alkaline. The predecessor of the experimental plots was corn for grain. It was found that at early sowing dates (April 20 - May 5) resulted in higher field germination (87-93%), plant foliage of 46.9 thousand m2/ha and their survival rate for harvesting 84-91%. More nodules formed on the roots of the plants. The maximum yield is 2.6 t/ha, obtained during sowing on April 30.
