The activities of the growing population in Pondicherry urban agglomeration, with increasing industries have exerted an enormous pressure on its fragile environment. The lack of proper drainage and improper liquid and solid waste management has led to the breakdown of sanitary facilities. This has created conditions conducive to the proliferation of many disease vectors. The risk of infection w...

Proper N fertilizer and irrigation management can reduce nitrate leaching while maintaining crop yield, which is critical to enhance the sustainability of vegetable production on soils with poor water and nutrient-holding capacities. This study evaluated different methods to measure nitrate leaching in mulched drip-irrigated zucchini, pepper, and tomato production systems. Fertigation rates wer...

Reuse of saline subsurface drainage water for irrigation has been identi®ed as a potential option for managing drainage volumes and sustaining crop productivity in California's San Joaquin Valley. Soil surface structural instability, crusting and poor stand establishment may, however, be constraints in drainage reuse systems. The objective of this ®eld study was to evaluate the effectiveness of...
