Abstract:
A field experiment was carried out at college farm of N. M. college of Agriculture, Navsari Agricultural University, Navsari, to study the "Effect of Intercropping and Weed Management on Rabi Sorghum (Sorghum bicolour L.,) Under South Gujarat Condition." During Rabi season 2019. The soil of experimental unit was clayey (57.22) in texture with poor drainage and good water holding capacity. The experiment site was low in organic carbon (0.32%), low in available N (227.30 kg/ha), medium in available P2O5 (32.74 kg/ha) and high in available K2O (374.65 kg/ha) with pH 7.9 and EC 0.36 ds/m. there were twelve treatment combination consisting of sole sorghum, sole Indian bean, sorghum + Indian bean (3:2), weedy check, pendimethalin 1 kg/ha and pendimethalin 1 kg/ha + HW at 30 days were evaluated with randomized block design with factorial concept with three replication. Grain yield and fodder yield of sorghum were significantly affected due to intercropping and weed management practices and the significantly the highest value were found with treatment I1 (sole sorghum). However, it remains statistically at par with treatment I3 (sorghum + Indian bean 2:1). Harvest index remained unaffected due to different intercropping and weed management practices as well as in interaction. Significantly lower weed count of monocot, dicot and sedges and dry weight of weeds recorded with treatment I4 (sorghum + Indian bean 2:1) at 20 and 40 DAS for weed count. While highest weed control efficiency (WCE) and lowest weed competition index (WCI) was recorded with treatment W3 (pendimethalin 1 kg/ha + HW at 30 DAS) and treatment I4 (sorghum + India bean 3:2).
