Effect of sowing dates and weed management on yield of lentil (Lens culinaris Medik.)

Abstract

The present study entitled “Effect of sowing dates and weed management on growth, yield and economics of lentil (Lens culinaris Medik.)” was carried out during kharif 2020-21 at instructional cum research farm, D.K.S. College of Agriculture and Research Station, Bhatapara (C.G.). The soil of the experiment side was clay- loam texture. The lentil crop was grown in treatments were replicated three times in split plot design. The experimental consists of main plot treatments viz. D1: 10/11/2020, D2: 20/11/2020, D3: 30/11/2020 and D4: 10/12/2020 and sub plot treatments viz. W1: Weedy check, W2: Pendimethalin 30% EC @ 1 kg a.i./ha (PE) + Imazethapyr 10% SL @ 37.5 g a.i./ha (PoE), W3: Pendimethalin 30% EC @ 1 kg a.i./ha (PE) + Imazethapyr 35% + Imazamox 35% WG @ 70 g/ha (PoE) and W4: Weed free.The result revealed that maximum value of observation on, yield attributes and yield of lentil recorded under main plot D1 (10/11/2020), While lowest were recorded under treatment control treatment D4 (10/12/2020) and maximum recorded under sub plot treatment (Pendimethalin 30% EC @ 1 kg a.i./ha (PE) + Imazethapyr 35% + Imazamox 35% WG @ 70 g/ha (PoE). While lowest were recorded under treatment control treatmentW1 (Weedy check).Among the different date of sowing, the sowing on 10th November was recorded higher values regarding yield attributes were higher in treatment W4 (Weed free).
