Economic feasibility of a narrow row method of growing carrot seeds at non-transplanting culture in the conditions of Stavropol region

Abstract

The influence of three schemes of carrot sowing was studied: sowing with a vegetable seeder VS-4.2 with row spacing of 70 cm, a grain seeder GS-5.4 with row spacing of 15 cm and a MaterMacc seeder using a 25+20x20x20x20x20+25 cm – on the seed yield, their sowing qualities and economic efficiency of non-transplanting seed production. The studies found that the use of MaterMacc seeder in direct seed production of carrot varieties Marlinka provides the necessary density and high survival rate of plants after overwintering, at the same time, on one hectare, testes of the first and second types of branching are formed with more complete seeds. The use of different seeding schemes did not significantly affect the mass of 1000 seeds. Seed germination rates also did not depend on the seeding scheme, but the greatest germination was observed in the control and experiment with the MaterMacc seeder. The new technology using the MaterMacc seeder allows increasing the yield of seeds by 3.2 times, reduce their cost by 3 times and achieve a profitability level of 288.8%.
