Mandra Vamsidhar Reddy, Rajesh Singh and Pratyasha Tripathi DOI: https://doi.org/10.22271/tpi.2022.v11.i5m.12524 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 25 0 30’ 42’’N latitude, 81 0 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). Keywords: Nitrogen, iron, growth, yield and economics Introduction Chickpea (Cicer arietinum L.) is an important crop for vegetarian people as primary source of protein, it is third most important pulse crop grown in the world after dry beans and peas (Kaur et al., 2020). India ranks first in area and production of chickpea followed by Australia, Pakistan and Turkey. As per 4th advance estimates, it accounts an acreage of 10.17 million hectares contributing 11.35 million tonnes of production with an average productivity of 1,116 kg/ha during 2019-20 in India. Among states, Rajasthan, Madhya Pradesh, Maharashtra, Karnataka, Bihar, Andhra Pradesh, Tamil Nadu and Gujarat are primarily growing states of chickpea. Moreover, it has occupied on 2.46 million hectares with a production of 2.66 million tonnes and productivity of 1,080 kg/ha in Rajasthan (DES, 2020) [1] . This crop is tolerant to drought, can be grown successfully on well drained loamy to sandy loam soils under residual moisture (Yadav et al., 2019) [11] . Nitrogen is required for both vegetative and reproductive growth of a crop. It is primarily applied to agricultural crops through the soil. Foliar nitrogen administration, on the other hand, effectively boosts both vegetative and reproductive growth. Photosynthates are used for root nodule formation and function during early development of grain legumes, but as flowering begins, the developing seeds require higher nitrogen levels. As a result, leaf nitrogen is redirected to grain filling, resulting in blossom shedding and a poor sink realization. Nitrogen added during flowering boosts pod setting and production. Iron (Fe) plays an important role in chlorophyll synthesis and act as structural component of hemes, hematin and leghaemoglobin involved in the nitrogen fixation in pulses catalysed by an enzyme called “nitrogenase” (Larson et al., 2018) [7] . Moreover, iron is the most essential micronutrient for plant growth especially for chickpea grown on saline and alkaline soils (Larson et al., 2015) [6] . Materials and Methods The experiment carried out during rabi season of 2021 at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj (U.P.). which is located at 25 0 30’ 42’’N latitude, 81 0 60’ 56” E longitude, and a height of 98 metres above sea level.The soil texture in the experimental plot was sandy loam, with a practically neutral soil reaction (PH 7.1), low organic carbon (0.44 percent), available N (171.48 kg/ha), available P (27.0 kg/ha),
