The article presents the results of studies conducted in the conditions of the indigenous bank of the middle course of the Lena River in Central Yakutia to study the accelerated reproduction of Vetch seeds when determining the seeding rates and the multiplication factor. It was established that, depending on the seeding rate during the vegetation period, the growth energy of the plants of the Vetch sowing plant is 0.70-0.82 cm / day, while the higher the rate, the lower the daily gain. The maximum yield of seeds 14.6 centners per hectare is ensured at the control (seeding rate 2.0 million / hectare). The multiplication factor in the control variant was 16, with a decrease in the norm to 1.5 million / ha of viable seeds, the coefficient was 18, to 1.0 million to 26. For accelerated reproduction of seeds, a decrease in the seeding rate to 1.0 million is recommended. seed germination per hectare with a multiplication factor of 26.
