Contribution of management of irrigation water and organic application in improving some soil properties and its water productivity of sugar beet and cotton
Two field trials were carried out at the experimental farm, Sakha agricultural research station, Kafr El-Sheikh Governorate, Egypt during two successive growing seasons (winter 2018/2019) and (summer 2019). The aim of this study was to investigate the impact of management of irrigation water and organic-fertilization as partial replacement instead of mineral fertilizers application on some soil properties and yield-water productivity of sugar beet and cotton in salt affected soil. The main investigated factors included irrigation treatments at 80,100 and120%, respectively from evaporation pan class A. The fertilization treatments included applying N-fertilizer at three rates of 100, 80 and 60 % N from recommended dose in combination with compost as (0, 20 and 40%). Two levels of potassium humate (i.e., 12 and 24kg ha-1) were also applied. The results showed that cation exchange capacity (C.E.C), soil organic matter, infiltration rate, IR(cmh-1) and hydraulic conductivity were influenced by the individual treatments and recorded the most efficient values due to the interaction of I1*N3*H2 after sugar beet and cotton cultivation. Water productivity (WP), productivity of irrigation water (PIW), economic yield and economic from water unit for sugar beet and cotton crops were significantly increased and recorded the highest values with the interaction of I1*N3*H2 of treatments. Therefore, the irrigation and fertilization management could be considered a proper approach to sustain the soil and water resources in particular under arid and semi-arid regions.
