Vestnik OrelGAU, 4(49), August 2014 UDC 635.656 STUDYING OF A NITROGEN-FIXING AND PRODUCTIONAL ABILITY OF DIFFERENT VARIETIES OF SOYA BEAN Vasilchikov A.G., Candidate of Biological Sciences Akulov A.S., Candidate of Agricultural Sciences All-Russia Scientific Research Institute of Grain legumes and Cereal Crops E-mail: office@vniizbk.orel.ru ABSTRACT The research results on studying of an influence of an inoculation and mineral nitrogen application for symbiotic activity and seed production of different varieties of soya bean are presented in this article. <...> All these researches were conducted in the All-Russia Scientific Research Institute of grain legumes and cereal crops in 2011- 2013. <...> Symbiotic and productive ability of new soya varieties Zusha and Mezenka in comparison with the standard Lantsetnaya variety is studied. <...> It is established that formation of the symbiotic device and its activity depended on a preseeding inoculation of seeds bacterial fertilizer (nitragin) and also on presence of spontaneous populations of rhizobium in the soil. <...> The period duration of a symbiotic nitrogen-fixing depended on varietal features and was longer at Zusha and Mezenka's more late-season varieties. <...> Seeds inoculation by nitragin was surpassed in efficiency of mineral nitrogen application in a dose of 60 kg per hectare. <...> Different reactions of varieties when forming a crop on distribution of rainfall during the growth season was noted. <...> Having prevalence of rainfall in the first half of summer on formation of a crop early ripening varieties which used spring soil deposits of moisture and rainfall of May-June more rationally had advantage, less suffering from a JulyAugust drought and a heat. <...> Soya cultivation development program accepted in Russia plans to increase cultivated areas by 2017 to 2.7 million hectares, including in Central district (Belgorod, Voronezh, Orel) to 500 thousand hectares [1]. <...> Soya expansion to new, more northern regions of cultivation (width 48-520) became possible in connection with creation and introduction in production of early ripening varieties of northern ecotype with growing season length about 100 - 115 days, such as Lantsetnaya, Svapa and others, steadily ripping in the conditions of the Orel region. <...> According to forecasts of climatologists, ground temperature can increase on 1.4-5.80 C by the end of 21 centuries that will lead to lengthening of the crop season for 1.5 months, and the annual sum <...>
