WATER-SAVING TECHNOLOGIES FOR DRIP IRRIGATION OF COTTON IN THE SOUTH OF RUSSIA
Abstract
The article presents the results of research in 2019–2020 about 4 modes of drip irrigation with maintaining of the Soil Pre-Irrigation Moisture (SPIM) 65-65-60, 70-70-65, 75-75-70, 80-80-75 % of Full Moisture Capacity (FMC), as well as 4 doses of mineral fertilizers with quantity of N70P30K23, N105P45K34, N140P60K45 and N175P75K56 kg/ha in the south of Russia. As a result of the completed field experiments, it was found that the highest yield of raw cotton of 5.33 t/ha was obtained while maintaining SPIM 75-75-70 % of FMC and applying fertilizers with doses of N175P75K56 kg/ha. The maintaining such a level of water supply and mineral nutrition made it possible to obtain the minimum values of the Water Total Consumption Coefficients (WTCC) of 46,6 mm/t and the Irrigation Water Expenses (IWE) 22.8 mm/ton, which, in comparison with other studied variants, made it possible to reduce the Total Water Consumption (Volume of Irrigation Water, Rainfalls, Soil Moisture Reserves) and the consumption of irrigation water alone to obtain 1 ton of raw cotton, respectively, up to 91,6 and 39,2 mm/ton, or up to 163,8 and 162,1%. The comparison with the control showed that drip irrigation, in comparison with furrow irrigation, made it possible to increase the yield of raw cotton by 1,.37 t/ha or 30,8%. At the same time, the total consumption of water and the consumption only of irrigation water to obtain 1 ton of raw cotton decreased by 74,8 and 76,4 mm or respectively, by 134,2 and 280,6%.
