Influence of seed rate and fertilizer levels on growth and yield of lentil (Lens culinaris Medik.) genotypes under dry land situation

Abstract: The Field experiment was conducted at Regional Agricultural Research Station, Vijayapura in Northern dry zone of Karnataka on medium black soil to study the influence of seed rate and fertilizer levels on growth and yield of lentil (Lens culinaris Medik.) genotypes under dry land situation during rabi 2015-16. The experiment was laid out in Split split plot design with three genotypes as main plot (JL 3, IPL 316 and RVL 31), three seed rates as sub plot (30, 35 and 40 kg ha-1) and two fertilizer levels as sub sub plot (25:50:25 kg and 10:30:00 kg N, P2O5 and K2O ha-1) treatments. The lentil genotype RVL-31 recorded significantly higher grain yield (130.7 kg ha-1) and was on par with genotype JL-3 (121.0 kg ha-1). Significantly higher yield was attributed to significantly higher growth and yield parameters viz., plant height at 60 DAS (20.7 and 19.7 cm, respectively), 100 seed weight (2.92 and 3.00 g, respectively) and harvest index (19.25 % and 16.39 %, respectively). The seed rate of 40 kg ha-1 recorded significantly higher grain yield (135.2 kg ha-1), benefit cost ratio (1.09), straw yield (817.9 kg ha-1), harvest index (17.3 %) and higher number of plants per m row length at 60 and at harvest (39.1 and 29.2, respectively). The fertilizer level of 25:50:25 kg N, P2O5 and K2O ha-1 recorded significantly higher grain yield (123.2 kg ha-1), straw yield (801.2 kg ha-1) and harvest index (15.95 %) compared to 10:30:00 kg N, P2O5 and K2O ha-1. The interaction of lentil genotype, RVL 31 with 40 kg ha-1 seed rate and fertilizer level of 25:50:25 kg N:P2O5:K2O ha-1 recorded significantly higher grain yield (243.4 kg ha-1) and benefit cost ratio (1.70) with better performance of growth and yield parameters.
