Abstract:
A field experiment was conducted to study the “Effect of different planting densities and fertility levels on growth and yield of chickpea (Cicer arietinum L.)” It was laid out during Rabi season 2020 on sandy loam textured soil at Central Crop Research Farm, Department of Agronomy, SHUATS, Allahabad, (U.P.). The treatments comprised of different plant spacing e.g. (30cm x 15cm,40cm x 15cm, 50cm x 15cm) and also different fertility levels (e.g. 40 kg of phosphorous/ha,50kg of phosphorous/ha and 60kg of phosphorous/ha). There were 9 treatments each replicated thrice. The experiment was laid out in Randomized Block Design with three replications. Results showed that the growth parameters e.g. plant height (49.61cm), number of primary branches per plant (8.27), Dry weight (14.42gm), CGR (5.72 g m-2 day-1), RGR (0.124g/g/day), nodules per plant (40.66) and yield attributes e.g. pods per plant (45.20), seeds per pod (1.27), seed index (29.16gm), grain yield (18.65q/ha), Straw yield ( 20.45q/ha) and harvest index(47.69%) were recorded maximum by the application of 40cm x 15cm + 60kg of phosphorous/ha. However, the gross return (₹1,05,340 /ha), net return (₹67,402.3 /ha) and B:C ratio of (1.77) were recorded higher with the application of 40cm x 15cm + 60 kg of phosphorous/ha.
