Response of Lentil (Lens culinaris Medik) to Sowing Time and Fertilizer dose under New Alluvial Zone of West Bengal

摘要

Field experiments were conducted for three years at Pulses and Oilseeds Research Station, Berhampore, Murshidabad, West Bengal, India during rabi 2008-09, 2009-10 and 2010-11 to study the response of lentil to varying sowing time and fertilizer doses. The experiment was laid out in a factorial randomized block design with four replications having nine treatment combinations viz. three levels of sowing time ( Dt - sowing on 18,h October, D, - sowing on Is' November, D3 - sowing on 15"1 November ) as factor A and three levels of fertilizer dose (F, - 20,40,40 kg N, P,Os, K,0 per ha, F, - 30,60,60 kg N, P_7O_5, K,0 per ha, F} - 40,80,80 kg N, P,Os, K0O per ha) as factor B. Experimental results revealed that growth, yield attributing characters and seed yield of lentil cultivar WBL-58 were significantly influenced by sowing time, fertilizer do&e and interaction effects of these two factors. Irrespective of fertilizer doses, sowing on 15th November gave significantly higher seed yield (1533.2 kg ha~(-1)).Application of 40, 80, 80 kg N, P_7O_5, K,0 per ha significantly improved the seed yield of lentil (1424 kg ha~(-1)) irrespective of sowing time. Among the interaction effects the highest seed yield of lentil (1654.4 kg ha~(-1)) was recorded with sowingon 15th November along with application of 40,80,80 kg N, P_7O_5, K,0 per ha.
