 ABSTRACT

An experiment was conducted on the efficacy of herbicides and cultural practices on weed flora and weed density at different days after transplanting in kharif brinjal crop under Hyderabad Deccan conditions. The experiment was laid out in randomized block design with thirteen treatments combinations and replicated thrice. Among the different weed species observed, the most dominant species were broad leaved weeds (BLW) viz., Parthenium hysterophorus, Digera arvensis, Euphorbia hirta, Phyllanthus niruri and Amarathus viridis. The important grasses were Cynodon dactylon and Dactyloctenium aegyptium and sedges viz., Cyperus rotundus. Different integrated weed management practices had a significant effect on weed density at all the stages of crop growth and control plot recorded significantly maximum number of broad leaved weeds (BLW), grasses and sedges when compared to treated plots. With respect to weed dry matter per square meter, glyphosate @ 1.5 kg a.i. ha-1 directed spray at 25 and 50 DAT and pendimethalin C.S as  pre-emergence @0.70 kg a.i ha-1 + one hand weeding at 45 DAT  recorded significantly the lowest dry weight of broad leaved weeds, grasses and sedges at all the stages of crop growth.

Key words: Brinjal plot, Weed flora, Weed density.
