Soldatenko O. Elements resource-saving technologies of cultivation seeds of cucumber in Eastern forest-Steppe of Ukraine.

Object: regularities of the process of formation of a high level of productivity and quality of seeds of cucumber depending on the elements of technology of cultivation in the Eastern forest-Steppe of Ukraine. Objective: to determine the effectiveness of the elements of technology of cultivation of seeds of cucumber to increase yield and seed quality, increase the profitability of its production and lowering the cost per unit of output. Results: the regularities of formation of a high level of productivity and quality of seeds of cucumber, the calculated coefficients of water consumption of plants, found a significant correlation between yields and biometric indicators (r=0.82-0.96). For growing seeds of cucumber sorto-types of Nіzhinsky should: locally to make fertilizers in the soil in the spring based N30P60K45; layout (50+90)X20 cm, density of plants 70 tis. pcs. / ha; use of drip irrigation with the level before irrigation soil humidity to mass flowering 80-75 % NV, irrigation rate 125 m3/ha; to phase fruiting to fruit ripening - 70-65% HB norm 225 m3/ha; hold two fertigation on N15 in a phase 3-4 real leaves and in the beginning of flowering; to collect seed fruits for 41-45 days from the mass flowering female flowers; select seeds without dozarivaniya (ripening) fruits that provides a high level of the yield (202 kg/ha) regulatory quality, while increasing profitability (to 56.8 %) and reduction of the cost price (71 UAH/kg) and energy (33%) in comparison with standard technology.
