SOWING TIME AND SEEDING RATE OPTIMISATION UNDER ADAPTIVE MANAGEMENT OF VIOLA VARIETY WINTER WHEAT CULTIVATION TECHNOLOGY

Abstract

One of the defining periods in the life of plants is the sowing of winter crops (autumn) period. Only when a good ensure moisture and at an optimal temperature of air in this period it is possible to obtain timely and quality shoots, forming shoots tillering and percolation processes utilization and hardening plants. Given the importance of the foregoing, this paper presents the results of research in the context of the Institute of agricultural technology and seed-the branch winter wheat varieties of locality Viola at different dates of sowing norm and seeding. It is established that the different timing of sowing plant survival ranged -87.5- 57.9%. Significant differences on wintering plants between crops of different sowing dates have been identified. Seeding rate had no significant effect on plant height, ear length and number of grains in an ear. Indicating a high plasticity of winter wheat varieties Viola. The greatest influence on the grain yield had a weight of 1000 grains (r = 0.78) and number of grains per ear (r = 0.63). Our research has shown that for winter wheat varieties of Viola in the midst of the Ryazan region favourable term of sowing is the period from 5 to 10 September with optimum seeding rate 4.5 million.
