Title : Assessment of poor quality irrigation water under different cropping systems in arid and semi-arid region, India.

Abstract :

The study was conducted to assessment of poor quality irrigation water under different cropping systems in arid and semi-arid region, India. The quality of irrigation was high SAR saline (EC= 6.1 dS m-1, SAR=10.6 mmol l−11/2) in sugarcane and rice-wheat, and marginally saline (EC= 2.7-3.8 dS m-1; SAR = 5.3-7.5 mmol l−11/2) in guar-wheat, and cotton wheat cropping systems. The SOC ranged from 3.52 to 8.98 g kg-1 under different cropping systems. Among the different cropping systems, sugarcane (8.98 g kg-1) cropping system possessed higher SOC content followed by rice-wheat (6.49 g kg-1), guar-wheat (4.99 g kg-1), moth bean-chickpea (4.93 g kg-1), cotton-wheat (3.85 g kg-1) groundnut-wheat (3.52 g kg-1). Saline water is widely used as an alternative water resource for agriculture production to overcome the freshwater shortage in arid and semiarid regions. But long-term using of the saline water for irrigation would negatively affect soil properties and crop production. the salinity and high SAR of the irrigation water should be properly managed to reduce the risks.
