Increasing Application Efficiency of Supplemental Irrigation by Adding the Water in the Root Distribution Zoon
Soil and water Conservation Department, Desert Research Center (DRC), Cairo, Egypt.
Abstract
A new buried irrigation system was applied as supplemental irrigation system, with the goal of enhancing its application efficiency in accordance with climate change challenges and water scarcity through increasing soil moisture content, water saving and Water use efficiency for longest period possible surrounding the root distribution zone to avoid the critical period of rainless and drought and maximizing the olive fruit productivity. The field experiment was conducted in a 5-year-old olive orchard located at Wadi El Raml, Matrouh Governorate. The study extended for two consecutive winter seasons (2018-2020),under semi-arid climate conditions of Egypt. Two main supplemental irrigation system were used: Drip (DI) and buried irrigation (BI) which rely on a perforated pipes under the soil surface depths of 30 and 40 cm. At rates of organic matter 1 and 1.5 Ton.fed-1 were added to the soil. The highest preferable values of soil moisture content, water storage and olive yield productivity obtained from buried supplemental irrigation at depth of 40 cm (BI40cm) and organic matter 1.5 Ton.fed-1,while the lowest values were obtained from non-supplemental irrigated treatment (only rain-fed conditions). Hence, it is recommended that farmers urgently need to apply the supplemental irrigation technique to obtain the desired yield. This study will support the successful usage of the buried supplemental irrigation system to improve soil water storage water use efficiency and enhance yield productivity during rainless period.
