An experiment was conducted on weed management practices on weed control efficiency, growth parameters and yield in kharif season brinjal at Vegetable Research Station, Agriculture Research Institute, Rajendranagar, Hyderabad, during kharif. The experiment was laid out in randomized block design with thirteen treatment combinations and replicated thrice. Among the treatments, significantly the highest nitrogen uptake (180.45 kg ha-1), phosphorus uptake (142.22 kg ha-1), potassium uptake (95.85 kg ha-1) was observed with hand weeding three times at 20, 40 and 60 days after transplanting. With respect to growth parameters, treatment T6 recorded the highest plant height at 20 Days after transplanting (DAT) (17.38 cm) and Treatment T12 (hand weeding three times at 20, 40 and 60 DAT) had highest plant height (31.85 cm.) at 40 Days after transplanting. The highest plant height at 60days after transplanting was recorded in pendimethalin C.S as pre-emergence @ 0.70 kg a.i ha-1 + one hand weeding at 45 DAT (T1) (56.52 cm.). whereas at 80 days after transplanting, the highest plant height was found with hand weeding three times at 20, 40 and 60 DAT (T12) (74.69 cm). Highest number of primary branches and plant spread were recorded in hand weeding three times at 20, 40 and 60 DAT (T12) (6.36), (0.34 m-2). With respect to plant population, there was no significant difference between the treatments. The highest fruit yield (31.10 t ha-1) was noticed with hand weeding three times at 20, 40 and 60 days after transplanting.
