Abstract


A field experiment was conducted at College of Agriculture, Dharwad for two rabi seasons to know the effect of plant densities and phosphorus levels on uptake of nutrients and protein content in kabuli chickpea genotypes. The chickpea genotype ICCV –2 recorded 7 and 14 per cent higher nitrogen (64.94 kg/ha) and  phosphorus (17.44 kg/ha)  uptake and 4% protein (23.69%) content as compared to B.G-267. The higher plant density of 4.44 lakhs/ha  recorded significantly more nitrogen (68.28 kg/ha) and  phosphorus uptake (20.55 kg/ha) as compared to lower plant densities. The phosphorus  uptake  decreased from 16.73 to 15.64 kg/ha with increase in phosphorus levels % thus indicating 50 kg P2O5/ha could be the optimum dose for chickpea. While the protein  content increased from 22.10 to 24.12%  with increase in phosphorus  levels. The increase in nitrogen  and phosphorus  uptake was mainly attributed to higher seed and bhusa yield.
