Abstract

The crop yield and water productivity is a complex indicator because it can be ascribed mainly to agro-techniques, plant factors, and environment. Appropriate crop management strategies to improve yield and water productivity should be taken into account of these different factors and their potential interactions. Studying different factors and their interactions affecting yield and water productivity of crops are difficult, time consuming and detailed insights into the system behavior in space and time. A study was undertaken to assess the ability of the CropSyst model to predict yields, and nitrogen uptake of cotton, clusterbean, wheat, and Indian mustard in IGNP stage-I of north-western Rajasthan.
