Abstract: A field experiment entitled “Response of rabi sorghum (Sorghum bicolor L.) on different levels of irrigation, nitrogen and banana pseudostem sap and its residual effect on summer greengram (Vigna radiata L.) under South Gujarat condition†was carried out during rabi season of 2016-17 and 2017-18 at college farm of Soil and Water Management Research Farm, Navsari Agricultural University, Navsari. The soil was clayey in texture, rich in organic carbon, medium in available nitrogen, P2O5 and K2O with alkaline in reaction (pH 7.8). Total twelve treatment combinations, consisting of four irrigation schedule based on IW:CPE ratio (I1=0.4, I2=0.6 and I3=0.8) and three nitrogen levels (N1= 60 kg N ha-1, N2= 80 kg N ha-1 and N3= 100 kg N ha-1) were tested in a split plot design with four replications. The results indicated that scheduling irrigation at an IW:CPE ratio of 0.8 recorded significantly higher values of almost all the growth characters, yield attributes as well as seed and stover yields of sorghum over 0.6 and 0.8 IW:CPE ratios and remained statistically at par with IW:CPE ratio of 0.8. Days to 50% flowering and maturity were delayed under this IW:CPE ratio. Whereas, higher WUE was obtained when crop was irrigated at 0.4 IW:CPE ratio. Almost all the growth characters, yield attributes, seed and stover yields were found significantly higher when crop has given nitrogen application at 100 kg N ha-1 than that over lower dose of nitrogen.
