Effect of Pendimethalin on Weed flora and Yield component of Brinjal under Agro-climatic condition of Tripura

The field experiments were carried out at the “Instructional farm” of Krishi Vigyan Kendra, West Tripura, Chebri, Tripura during Rabi season of 2014 to evaluate the effect of pendimethalin in controlling weeds of Brinjal (Solanum melongena L.). Treatment comprised of T₁: Hand weeding at 30 DAT, T₂: Pendimethalin (@ 1.5 lit/ha): 3–5 DAT, T₃: Pendimethalin (@ 1.5 lit/ha) 3–5 DAT + Hand weeding 30 DAT, T₄: Control. It is observed that weed dry matter at all the stages of crop growth period is significantly higher in case of un weeded control due to unchecked growth of weeds; lowest weed dry biomass 4.34, 11.49, 33.54 and highest weed control efficiency (WCE %) 84.23, 73.39, 47.61 recorded at 30, 60 and 90 DAT incase of Pendimethalin (@ 1.5 lit ha⁻¹ at 3–5 DAT + Hand Weeding at 30 DAT at all the stages of crop along with highest yield attribute 21.43t/ha.
