Abstract

The results of long-term studies of botanical, biological and agrotechnical features of the new introduced fodder culture Nicandra physaloides are presented. The maximum field germination (76.5%) was after sowing with a row spacing of 30 cm and a seeding rate of 0.15 million pcs / ha. The assimilation apparatus of Nikandra is formed in close dependence on weather conditions, the vegetation phase, and growing techniques. The maximum rates of leaf surface formation were in the budding – flowering phase. With an increase in planting density, the leaf surface increases and reaches the highest rates (45.50 thousand m2 / ha) with a seeding rate of 0.25 million pcs / ha in sowing with a row spacing of 45 cm, which is 1.4 times lower than with a minimum seeding rate (0.15 million pcs / ha) and the same sowing method. The accumulation of green and dry biomass took place analogously to the formation of the leaf surface. On average, over the years of research, maximum results on the yield of green mass (40.3 t / ha), the number of feed units (7.52 t / ha), digestible protein (1.06 t / ha), the content of digestible protein in 1 fodder unit (140.8 g) was after a wide-row sowing method (45.0 cm) and a seeding rate of 0.2 million pcs / ha. It is shown that a decrease and an increase in the seeding rate leads to a decrease in the biomass yield of the Nikandra by 12–15%.
