Effect of phosphorus and iron levels on growth and economics of Chickpea (Cicer arietinum L.)

Abstract

The investigation was carried out to study in rabi 2019 to study the effect of Phosphorus and Iron on growth and yield of chickpea (Cicer arietinum L.). The experiment consists of nine treatments replicated thrice laid out in Randomized Block Design. The treatment consisted of micronutrients viz. Phosphorus at 20 kg/ha, 40 kg/ha and 60 kg/ha and Iron 2 kg/ha, 4 kg/ha and 6 kg/ha whose effect is observed on Chickpea. Among the treatments it was observed that the treatment with application of 60 kg/ha Phosphorus + 6 kg/ha Iron was found to be the best treatment for obtaining growth and economics. Growth parameters such as plant height (70.71 cm), plant dry matter (24.49 g/plant) found to be maximum in treatment combination 60 kg/ha Phosphorus + 6 kg/ha Iron, crop growth rate (13.53 g/m2/day) and relative growth rate (0.021 g/g/day) found to be maximum in treatment combination 40 kg/ha Phosphorus + 2 kg/ha Iron. Economics viz., gross return (INR 128836.20/ha), net return (INR 82071.20), B:C ratio (1.75), was also recorded higher with the application of 60 kg/ha Phosphorus + 6 kg/ha Iron. Therefore, application of 60 kg/ha Phosphorus + 6 kg/ha Iron was more productive and economically feasible.
