Abstract

Irrigation practices on agricultural fields use more water than any other human activity. As a result, the sustainability of water use and food output is intimately tied to how fields are managed. This research was conducted to enhance the long-term viability of water and agricultural production. Soil amendments of compost and perlite were applied in an experiment to investigate the possibility of enhancing soil textures (sandy clay and silty clay) and, consequently, improving the production of crops and water sustainably. The Root Zone Water Quality Model (RZWQM2) was utilized to simulate the water dynamics and water requirement for wheat production under the combination of soil amendments and soil textures. Applied compost produced the highest crop yield, compared to the control treatment, with an increase of 6 - 21% and 2 - 9% in the sandy clay and silty clay, respectively. The interaction between sandy clay and compost treatment yielded the highest crop evapotranspiration of 508 and 375 mm per season for the first and second crop growing seasons, respectively. Using soil amendments decreased water leakage out of the root zone and improved water/wheat productivity. In addition, soil nitrate leaching away from the root zone was reduced by applying soil amendments. According to the findings, soil amendments successfully improved the productivity of both soil textures. Moreover, the compost treatment delivered superior outcomes, mainly when applied to sandy clay. Hence, evaluating other applications of soil amendments concerning soil texture types is recommended to improve the sustainable productivity of water and crops.
