Abstract:
A field experiment was carried out on clay soil during summer season of 2018 at College Farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari to evaluate the Performance of summer sorghum (Sorghum bicolor L.) under sole crop and different intercropping systems in south Gujarat condition. Total nine treatments viz., T₁ sole sorghum, T₂ sole sorghum (Paired rows at 30-60 cm), T₃ sole sorghum (Paired rows at 30-30-75 cm), T₄ sole greengram, T₅ sole blackgram, T₆ sorghum + greengram (Paired 2:1), T₇ sorghum + greengram (Paired 3:2), T₈ sorghum + blackgram (Paired 2:1) and T₉ sorghum + blackgram (Paired 3:2) were allocated in randomized block design with four replications. The soil of the experimental area was low in available nitrogen (185.26 kg ha^-1), high in available phosphorus (31.88 kg ha^-1) and potassium (390.41 kg ha^-1), slightly alkaline in reaction with normal electrical conductivity. Results indicated that sole sorghum (T₁) recorded significantly higher grain yield. Among all the treatments sorghum intercropped with greengram at 2:1 row ratio recorded higher sorghum equivalent yield, land equivalent ratio, net returns and B: C ratio.
