An experiment was conducted at the Field Laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh, during the period extended from November 2010 to March 2011 to study the effect of weeding on the growth and yield of three lentil varieties viz. BINA masur-1, BINA masur-2 and BINA masur-3. The experiment was laid out in a Randomized Complete Block Design with three replications. Growth and yield of lentil varieties have significantly been affected with a single hand weeding on 40 days after sowing (DAS). A single weeding operation significantly improved the plant height, number of branches plant-1, leaf area index, total dry matter, yield components like number of pods m-2, number of pods plant-1, number of seeds pod-1, number of seed plant-1, seed weight plant-1, seed yield, and harvest index as compared to the unweeded condition. However, seed yield did not show any significant variation due to combination of varieties and weeding regimes. The results indicate that, weeds in natural condition (unweeded) adversely affect lentil production and seed yield; whereas single hand weeding enhanced the growth, development and finally grain yield of lentil crop.
