A field experiment entitled “Effect of Weed Management on Weed Density, growth, and Productivity of Lentil (Lens culinaris Medik. L.)” was conducted during rabi 2021-22 at the Agronomy Instructional Farm, Rajasthan College of Agriculture, MPUAT, Udaipur. The experiment was arranged in Factorial Randomized Block Design (FRBD) consisting of 20 treatment combinations and three replications. Ten chemical weed control methods i.e., pendimethalin 500 g ha^-1 PE, pendimethalin 750 g ha^-1 PE, pendimethalin 1000 g ha^-1 PE, imazethapyr 50 g ha^-1 PoE, imazethapyr 60 g ha^-1 PoE, imazethapyr 70 g ha^-1 PoE, pendimethalin + imazethapyr 500 g ha^-1 PE, pendimethalin + imazethapyr 750 g ha^-1 PE, pendimethalin + imazethapyr 1000 g ha^-1 PE and control (No herbicides) were taken as factor A and HW at 40 DAS and control treatment were taken as factor B. Lentil variety Kota Masoor-3 was used as test crop. All the weed management treatments resulted in significantly higher net return from lentil crop. The maximum net return was realized by applying HW at 40 DAS which was 29.26 per cent higher over control (₹47645 ha^-1). The economic analysis of treatments in terms of B:C ratio reveals the highest B:C ratio (1.91) was obtained by Pendimethalin + Imazethapyr 1000 g ha^-1 PE which was significantly superior over control (1.64).
