Effect of nutrients and weed management on productivity of lentil (Lens culinaris L.)
Author(s): N. AGGARWAL AND H. RAM
Abstract: An experiment comprised of all combinations of four nutrient [FYM @ 15 t ha-1, recommended dose of 12.5 kg N and 20 kg P2O5 ha-1 (RDF), FYM+RDF and control] and three weed management [pre-emergence application of pendimethalin @ 0.45 kg ha-1, two hand weedings 30 and 60 days after sowing (DAS) and weedy check] treatments was conducted at PAU Seed Farm, Naraingarh in 2006-07 and 2007-08 in RBD with three replications. The application of FYM+RDF resulted in better growth of the crop and more weed suppression which consequently showed highest grain yield, gross returns and net returns in lentil. Pre-emergence application of pendimethalin @ 0.45 kg ha-1 proved slightly toxic for the crop during the initial stage of crop growth and the crop had dwarf plant with low yield attributes. Two hand weedings significantly reduced the weeds biomass and increased grain yield of lentil as compared to other weed control treatments..
