Abstract
An experiment was conducted during the Rabi season of 2012-13 and 2013-14 to examine the effects of fertility levels and weed management practices on weed density, growth parameters and yield of lentil (Lens culinaris Medikus). The experiment was laid out in split-plot design comprising six main plot treatments viz. Control (F0), 100% RDF (F1), 75% RDF + 2% urea spray at pre-flowering and pod initiation stage (F2), 75% RDF + Plantgro 9 kg/ha at 35, 50 and 65 DAS as foliar spray (F3), 100% RDF + 2% urea spray at pre-flowering and pod initiation stage (F4), 100% RDF+ Plantgro 9 kg/ha at 35, 50 and 65 DAS as foliar spray (F5) and four sub-plot treatments viz. unweeded (W0), weed free (W1), pendimethalin 1 kg a.i./ha (W2), imazethapyr 37.5 g a.i./ha (W3). The major group of weeds found in the experimental field was Cyperus rotundus, Chenopodium album, Solanum nigrum and Cynodon dactylon. The results indicated that fertility levels and weed management had a significant effect on weed population dynamics and lentil crop. Higher yield attributes, yield and harvest index was recorded with the treatment 75% RDF + Plantgro 9 kg/ha. Higher grain yield (1283.08 kg/ha) was recorded with 75% RDF + Plantgro 9 kg/ha whereas straw yield (2140.64 kg/ha), net returns 23218.09 (Rs./ha) and B:C ratio (2.29) was obtained with 100% RDF+ 2% urea spray. The increase in yield was 11.41 % and 29.83% over 100% RDF + 2% urea spray and control respectively. Highest N, P, K uptake (50.08, 7.29 and 22.92 kg/ha) respectively was recorded with 75% RDF + Plantgro 9 kg/ha. Total weed count and dry weight decreased significantly with the application of post-emergence application of imazethapyr 37.5 g/ha and was comparable to pendimethalin 1 kg/ha. Highest weed control efficiency of 68.87% was recorded with imazethapyr 37.5 g/ha. Higher grain yield (1088.05 kg/ha), straw yield (2121.43 kg/ha), net returns 22625.76 and B: C ratio (2.35) was recorded with imazethapyr 37.5 g/ha. This treatment also recorded the highest N (39.84 kg/ha), P (4.88 kg/ha), K (15.93 kg/ha) uptake and protein content (22.72%) of lentil.
