Water is the mainstay of agricultural economy of Pakistan. Irrigated agriculture provides 90 percent of our food and fiber requirements from 42.5 million acres that is around 80 percent of the cultivated area. The Indus basin irrigation system has a very large set-up and the Indus river delta is the seventh largest in the world. It involves a complex network of three large reservoirs, 16 barrages, two head works, 12 inter-river link canals, 44 canal systems and over 107,000 watercourses. Although the development of irrigation system has increased the productivity overtime but has also caused the problems of water-logging and salinity. These are the major problems limiting crop production in Pakistan. The present study has analyzed the impacts of water-logging and salinity on wheat productivity and ultimately on farm incomes by using econometric approach in District Muzaffargarh, PunjabPakistan. Results showed that salinity and water logging were negatively associated with wheat production. The co-efficients of sodium and chloride were negative but non-significant but the co-efficient of saturation percentage was highly significant
