My research and teaching interests are focused on integrated crop management with a particular emphasis on soil-plant-water-environment relationships, and issues related to biotic and abiotic stresses on crop production under both rainfed and irrigated conditions. I love working with agronomy and crop physiology using a systems approach, and believe – Sustainable and resilient agriculture is the way of the future.
