Продуктивність сої залежно від елементів технології вирощування в умовах Правобережного Лісостепу України

Abstract

A significant role in solving the problem of vegetable protein deficiency is playing soybeans, modern high-performance varieties of which, with developing and improving of adaptive components its growing technologies, are able to form consistently high yields of high-quality seeds. Among these components, selection of varieties, clarification of fertilizing doses and seed inoculation in accordance with soil and climatic conditions of a particular region, are of great importance. The purpose of research was to identify features of soybean productivity formation of different varieties depending on seeds inoculation and doses and timing of mineral fertilizers application in conditions of the Right-Bank Forest-Steppe. The experiment was laid during 2013–2015 in conditions of the SERF Salivonkivske of the Institute of Bioenergetic Crops and Sugar Beet of N AAS on typical low humus chernozems. According to the results of research, was established that in conditions of the Right-Bank Forest-Steppe of Ukraine the maximum yields studied hybrids formed under condition of combination seed treatment before sowing by phosphonitragin and application of N 30 P 60 K 60 like the main fertilizer and extra feeding N 15 in the budding phase, what allowed to obtain at early-ripening variety Vilshanka 2.91 t/ha and at mid-season variety Suzir’ya – 3.17 t/ha. Compared with the absolute control, the yield increase in these variants by 1.02 and 0.98 t/ha, respectively
