Ogallala Water

Dr. Prasad’s research interests primarily include: understanding crop responses to environmental factors (water, temperature, nutrients, and climate change factors) and to changes in genetics and crop management practices; and developing best management practices for efficient use of resources. His teaching interests include graduate level courses in crop physiology and in crop ecology. He provides leadership in interdisciplinary research, knowledge sharing, and capacity building activities on sustainable intensification for improving food and nutritional security of farmers. He has active research and capacity building program in Asia and Africa.

His role in the Ogallala Water CAP will be to work with crop modelers, agricultural engineers and agronomists to develop crop management practices that will increase resource use efficiency, productivity, profitability, resilience and sustainability of cropping systems, that will lead to improved livelihoods of people.

The ultimate and longer-term success of the Ogallala Water Coordinated Agriculture project will be based on the adoption of crop practices by the producers that will show measurable impacts on production, resources, and livelihoods of people.

Dr. Prasad notes: "The greatest opportunity we have in this project is to provide scientific evidence that we can simultaneous improve crop production and protect environment using principles of sustainable intensification."
