aref2 The researches were carried out on a grey forest light loam soil in microplot test. In different variants 5 seeding rates (from 0.4 to 0.8 million/hectare), 3 distances between rows at sowing (15, 45 or 60 cm) and 2 levels of soil fertility (without using of mineral fertilizers and with their application under conventional grain yield by 2.5 tons per hectare) were compared. The available moisture was used more efficiently in versions with seeding rate of 0.6, 0.7 and 0.8 million viable seeds per 1 hectare, with wide-row method of sowing with space between rows 45 and 60 cm when adding calculated NPK rates. A water consumption decline of these cases can be explain by the plants photosynthetic activity improvement, the biomass accumulation, as a result, and the formation of large grain yield of broad beans. The highest crop yield of broad beans (2.27 and 2.20 tons per hectare) was obtained by adding mineral fertilizers, sowing methods in wide space (45 and 60 cm) and seeding rate of 0.6 million viable seeds per 1 hectare. In these variants the best moisture content of crops and significant reduction in water consumption per unit of yield were observed on the average of 3 years.
