WATER SAVING OF RICE CROP USING INNOVATIVE TECHNIQUE FOR SOIL MANAGEMENT, SWMR

Abstract

The trial was conducted in, 2019 and 2020 Kafr-El Sheikh Governorate, Egypt, Rice (Sakha 104) was cultivated under two methods, traditional method (WTF3) and modified innovative method in furrow bottoms, soil and water management for rice cultivation (SWMR). The cross section of furrows is such as a zigzag shape using a soil management and soil bed preparation (soil surface shape) using innovative machine to soil bed preparation to harvest irrigation water. Without any reduction of rice intensity, and rice transplants at 40 ×40 cm in both of two cultivation methods. Besides, three treatments of nutrients (50, 75 and 100% of recommended doses and called WMF1, WMF2 and WMF3 respectively), irrigation system are traditional system for the first method and furrow irrigation systems for the modified innovative method, applied water amount and nutrients was measured, productivity parameters, economic and energy analysis. The results show that applied water in 2019 are 13104 and 6897 m3/ ha while in 2020 are 12510 and 6724 m3/ha, for the traditional and modified cultivation methods, Respectively. Rice yield in 2019 is 7589, 8282, 8987 and 8580 in 2020 is 7392, 8366, 8770 and 8376 kg/ha. For both of WMF1, WMF2, WMF3 and WTF3, respectively, finally, every parameters engaged with irrigation water is influenced according to the water foot print of rice is cut to half. SWMR technique can save about 20% of irrigation water will be saved in world.
