Field experiment was conducted on weed management practices in castor at the Agricultural College Farm, UAS, Raichur, during kharif 2015-16 and 2016-17 in the clay soil. Pooled mean of two years indicated that among the weed management treatments, application of pendimethalin 38.7% CS @ 1000 g a.i. ha-1 (PRE) fb imazethapyr 10% SL @ 75 g a.i. ha-1 (POE) recorded significantly higher herbicide efficiency index (0.0451), dehydrogenase activity (23.37 μg TPF formed g-1 soil hr-1) at 60 DAS. Whereas bacterial (12.25 per plate) and fungal population (8.61 per plate) at 15 DAH application was significantly higher with pendimethalin 38.7% CS @ 1000 g a.i. ha-1 (PRE) + 2 intercultivations at 30 and 60 DAS compared to other herbicidal treatments and was found at par with the application of pendimethalin 38.7% CS @ 1000 g a.i. ha-1 (PRE) fb imazethapyr 10% SL @ 75 g a.i. ha-1 (POE) at 30 DAS + IC at 60 DAS (12.04 and 8.40 per plate).
