Effect of Phosphorus and Iron on Growth and Yield of Chickpea (Cicer arietinum var. kabulium)

Abstract

The field experiment was conducted “Effect of Phosphorus and Iron on growth and yield of Chickpea (var. NBeG-119) during Rabi season, 2021-22 with 9 treatments (viz., Phosphorus at 30,40 and 50 kg/ha respectively and Iron at 3,5 and 7 kg/ha respectively) at the CRF (Crop Research Farm) Department of Agronomy, Sam Higginbottom University of Agriculture, Technology And Science, Prayagraj, Uttar Pradesh, India. The treatment compared T1- Phosphorus 30 kg/ha + Iron 3kg/ha, T2- Phosphorus 30 kg/ha + Iron 5kg/ha, T3- Phosphorus 30 kg/ha + Iron 7kg/ha, T4- Phosphorus 40 kg/ha + Iron 3kg/ha, T5- Phosphorus 40 kg/ha + Iron 5kg/ha, T6- Phosphorus 40 kg/ha + Iron 7kg/ha, T7- Phosphorus 50 kg/ha + Iron 3kg/ha, T8- Phosphorus 50 kg/ha + Iron 5kg/ha, T9- Phosphorus 50 kg/ha + Iron 7kg/ha. Application of phosphorus 40 kg/ha + Iron 5kg/ha recorded highest plant height (69.10 cm), plant dry weight (25.00 g/plant) number of branches per plant (2.33), number of nodules/plant (21.32), plant dry weight (25.00 g/plant) number of seeds/pod (1.93), seed index (309.83 g), seed yield (2.60 t/ha) stover yield (4.23 t/ha) Harvest index (38.08%) highest gross returns (156000.00 INR/ha) net returns (109340.00 INR/ha) and benefit cost ratio (2.34).
