An experiment was carried out at village Bajju, Bikaner, Rajasthan during kharif season of 2016 to Effect of Irrigation and Nitrogen Levels on Nitrogen Content, Uptake and Water Productivity of Clusterbean (Cymopsis tetragonoloba) in IGNP Stage-II. The treatment comprising three levels of irrigation (100, 200 and 300 mm) and four levels of nitrogen (0, 20, 40 and 60 kg N ha-1) comprising a total of twelve treatment combinations in split plot design with four replications. Increasing level of irrigation from 100 mm to 200 mm increased the yield and nitrogen uptake by seed, stover and total plant, water productivity and protein yield of clusterbean over 100 mm and remained at par with 300 mm. Application of 40 kg N ha-1 produced significantly highest yield, nitrogen content in seed and stover, nitrogen uptake by seed, stover and total plant, protein content in seed and protein yield of clusterbean over control and 20 kg N ha-1 but it remained at par with 60 kg N ha-1. Interaction effect of irrigation and nitrogen was also found significant for yield, nitrogen uptake and protein yield of clusterbean and highest values of these parameters were recorded with 200 mm irrigation in combination with 40 kg N ha-1.
