Impact of nitrogen and iron on yield attributes and economics of chickpea (Cicer arietinum L.)

Abstract

A field experiment was conducted during Rabi season 2021 at the experimental field of the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, India which is located at 250 30’ 42’’N latitude, 810 60’ 56” E longitude, and a height of 98 metres above sea level. The soil of the experimental field in Sandy loam in texture, nearly neutral in soil reaction (PH 7.1), low in organic carbon (0.36%) available N (171.48 kg/ha), available P (27.0 kg/ha) and K (291.2 kg/ha). The Experiment was laid out in Randomized Block Design with Nine treatments replicated thrice based on one year of experimentation. To determine the “Effect of Nitrogen and Iron on Yield attributes and economics of Chickpea (Cicer arietinum L.)”. The treatments consisted of three levels of Nitrogen – 15, 20 and 25 kg/ha and three levels of Iron – 2.5,5, 7.5 kg/ha. The results revealed that treatment with application of Nitrogen at 25 kg/ha + Iron at 7.5 kg/ha recorded significantly highest number of pods per plant (61.2), seeds per pod (3.5), seed index (26.00 g), seed yield (1919.1 kg/ha) and Haulm yield (3186.6 kg/ha), Maximum Gross return (INR 1, 01, 712.30/ha), Net return (INR 69,305.56/ha) and Benefit cost ratio (2.13).
