Now specific weight of one-year grain bean crops in the structure of cultivated areas in the terri-tory of Kemerovo Region remains low and in 2015 made 9230 hectares. Grain bean crops are pre-sented generally by two types: peas and fodder beans. It is necessary to develop the agrotechnology of cultivation of fodder beans for creation of food supply which in the conditions of Kemerovo Region has not been studied yet. Con-sidering biological features of fodder beans from processing methods of increasing efficiency, espe-cially it should be noted in sowing terms. In this regard the detection of features of development and conditions of formation of yield of fodder beans seeds depending on terms of sowing is actual. As the object of researches grades of fodder beans, Russians black and Windsor white were taken. By the authors it was established that the productivity of the fodder beans grown in the territory of the for-est-steppe of Kemerovo Region regardless of high-quality features is in direct dependence of the height of plants, the quantity of beans on one plant and seeds in a bean. At the first term of crops at both grades the productivity was higher and in lim-its of 2.6 t/hectare (Russians black) and 1.9 t/hectare (Windsor white), i.e. above the productivi-ty received at the second, third and fourth terms of crops. Fodder beans were capable of forming high productivity; however, this potential of the crop was not completely realized in this ecological niche as it significantly depended on external conditions of the environment, including the weather. The limiting factor of increasing fodder beans efficiency was the amount of precipitation during vegetation.
