SALINE IRRIGATION INFLUENCE ON QUINOA (CHENOPODIUM QUINOA) WATER PRODUCTIVITY UNDER MULCH IN THE LOWER INDUS BASIN
KAMRAN BAKSH SOOMRO
Abstract
Quinoa is highly tolerant of saline making it ideal for coastal regions due to its unique properties and nutritional value. To estimate the water productivity of quinoa Chenopodium quinoa using different qualities of Irrigation water under mulch. A furrow irrigation field experiment was carried out in 2023 and 2024. In the field, quinoa (Chenopodium quinoa) seeds were manually planted in rows separated by 0.5 meters. The furrow irrigation method was utilized to apply two types of irrigation water: EC 4.7 dS.m-1 with organic mulch (T1) and non-mulch with EC 3.9 dS.m-1 (T2). The difference between the two irrigation treatments including T1 and T2 for agronomic parameters are significant, as indicated by the Panicle Weight p-value of 0.0524, which is less than the significance level of 0.05. T1's water productivity was significantly higher than T2's, at 1.42, demonstrating the positive effects of mulch. T2's productivity was 1.15. As mulch helps reduce the adverse environmental effects of limited irrigation, this can be deduced. The experiment demonstrates that soil mulching significantly improves quinoa growth, yield, and water productivity under saline, semi-arid environments. Reiterating its position as a crop that is resilient and adaptive for future food security in a saline environment.
