Продуктивность и качество зерна озимой тритикале Инген 35 в многофакторном опыте

Abstract

The results of studies on the productivity and quality of grain of winter triticale Ingen 35 in a multifactorial experiment are presented. It was found that the highest grain yield was obtained from the predecessor peas for grains -4085 kg/ha, which significantly exceeded the value for the vetch-oat by 1381 kg/ha, for sunflower by 1252 kg/ha and corn for grain at 709 kg/ha. In terms of sowing terms, the maximum productivity of winter triticale was obtained at the optimum time of sowing (21.10) and for predecessors - peas for grain (4644 kg/ha), sunflower (3124 kg/ha) and corn for grain (3600 kg/ha). The level of influence on the yield of winter triticale variety Ingen 35 was highest for the predecessor (62,33%), the influence of the sowing terms was 36,38%. The influence of the seeding rate and the interaction of factors was less than 1%. The accumulation of crude protein in the grain of winter triticale after corn and sunflower was higher by 0,23 and 0,84% than after peas for grain. The minimum content of raw protein was aftre the predecessor vetch -oat -12,61%. According to all predecessor, the permissible (30.10) and the late planting period (21.11) exceeded the optimum sowing period by the accumulation of raw protein in the grain. Due to the higher yield of peas for grain, the highest yield of crude protein was -475,8 kg/ha, exceeding other predecessors by 67,2 and 189,5 kg/ha.
