Panasiuk R. Productivity of soybean cultivars depending on fertilization, seed rates and seeding methods under conditions of the western Forest-Steppeof Ukraine.

Subject of research - the processes of soybean variety growth, development and productivity formation depending on fertilizing, seeding rates and methods. The aim - the new heavy-productive soybean variety cultivation technology component improvement in the conditions of the westwrn UkrainianForest-Steppe. The research methods are field, calculating, visual, weight, biochemical, statistical, comparative and computational. The selection of new early-ripening and ultra-early heavy-productive soybean varieties is conducted and their cultivation technology components are improved for the conditions of the westwrn Ukrainian Forest-Steppe; the advantage of drill seeding method of soybean over wide-row one is determined, the optimum seeding rate of soybean seeds depending on ripening group is fixed. The recommendatios to production with the use of improved soybean cultivation technology what secures the obtaining of 2.7-3.4 t/ha grain with the protein content 35.0-36.2% and oil one 19.0-19.9% are worked out. The scientific developments are introduced in 2008-2010 at the agroformings of the Lviv Region over an area 129 ha. The field of application - the agricultural production.
