Abstract

The field experiment was carried out at research farm, Agricultural research sub-station, Hanumangarh, Swami Keshwanand Rajasthan Agricultural University, Bikaner during Kharif, 2016 to see the impact of different irrigation and nitrogen levels on water and nitrogen use efficiency of cluster bean (Cyamopsis tetragonoloba). For that, Cluster bean variety RGC-1055 with seed rate of 16 kg ha-1 was planted using 3 levels of irrigation (100, 200 and 300 mm) and 4 level of nitrogen (0, 20, 40 and 60 kg ha-1) and studied in Split plot Design with three replication. Results showed that the different irrigation and nitrogen levels significantly influenced the yield, total nitrogen uptake, water and nitrogen use efficiency and profitability of cluster bean. The irrigation level 200 mm recorded significantly superior grain yield, PEN, PFPN and economics over 100 mm. The total nitrogen uptake, AEN and REN were higher in irrigation level 300 mm over both the lower level. The irrigation water produ

Conclusion

From the results of the present investigation, it was concluded that irrigation at 200 mm found to be effective in improving the grain yield, PEN, PFPN, INUE and gross return of cluster bean. In different irrigation levels, irrigation at 100 mm found effective to enhance the irrigation water productivity of cluster bean. Among the nitrogen levels, application of 40 kg N ha-1 was found to be effective for improving grain yield, irrigation water productivity, PEN and INUE.
