Response of weed management practices and phosphorus levels on growth and yield of lentil (Lens culinaris Medik. L.)

A field experiment was conducted during 2024-25 at Agricultural Research Farm, School of Agricultural Sciences, Jaipur National University, Jaipur, Rajasthan to evaluate the Production of Lentil (Lens culinaris Medik. L.) as influenced by weed management practices and phosphorus. The experiment was laid out in Factorial Randomized Block Design with three replications. The experiment comprised four levels of phosphorus viz.; control, 15 kg P₂O₅ ha^-1, 30 kg P₂O₅ ha^-1 and 45 kg P₂O₅ ha^-1 and three weed management practices viz; weedy check, Hand weeding once 30 DAS and Pendimethalin@ 0.75kg a.i. ha^-1. The significantly higher growth parameters viz., plant height, number of branches, DMA, weed dry matter accumulation and maximum yield attributes and yield viz., pods plant^-1 (119.53), number of seeds pod^-1 (2.07), seed yield plant^-1 (2.10 g), test weight (31.04 g), seed yield (1400 kg ha^-1), stover yield (4406.67 kg ha^-1) and harvest index was obtained with the application of 45 kg P₂O₅ ha^-1 followed by 30 kg P₂O₅ ha^-1. Among the weed management practices, the application of pendimethalin @ 0.75kg a.i. ha^-1 gave significantly higher growth parameters viz., plant height, number of branches, DMA, weed dry matter accumulation; maximum yield attributes and yield viz., pods plant^-1 (115.51), number of seeds pod^-1 (2.00), seed yield plant^-1 (2.03 g), test weight (29.95 g), seed yield (1350.83 kg ha^-1), stover yield (4354.58 kg ha^-1) and harvest index.
