Ovcharuk O. Agroecological actions of realisation of potential of efficiency of grades of a string bean usual on grain in the conditions of a southern part of the western Forest-steppe of Ukraine

In dissertational work results of researches which shine features of growth, developments and formation of photosynthetic, symbiotic, individual and grain efficiency of grades of a string bean usual depending on influence of terms of sowing and harvesting terms are stated. It is resulted economic and power efficiency of elements of technology of cultivation of culture in the conditions of a southern part of the western Forest-steppe of Ukraine. The greatest quantity of productive knots was formed on plants of a string bean of grade Mavka at sowing at level of a thermal mode of a ground on depth of seeds 14°С. At this term of sowing of a plant of grade Mavka form a considerable quantity of beans from a plant - 10,1 pieces, grains from a plant - 39,4 piece, weight of grains from a plant - 8,8 On the basis of the received and generalised given results it is recommended to region agroformations to sow grade Mavka at daily average temperature of a ground on depth of seeds 14°С, string bean harvesting to spend at humidity of grain of 18 % that will provide productivity of the specified leguminous culture at level of 2,27 t/hectares.
