Effect of Phosphorous, Chloropyriphos and Rhizobium Inoculation on Production and Economics of Chickpea (Cicer aretinum L.)

Abstract

Field experiments were conducted to Studies effect of Phosphorus, Chloropyriphos and Rhizobium inoculants on productivity parameter and economics of chickpea during rabi season of 2020-21 and 2021-22 at students instructional farm, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur. The experiment consists of 18 treatments combinations in factorial randomized block design with three replications consisted of three levels of phosphorous (30, 60 and 90 kg ha-1), three chloropyriphos levels (0, 2.5 and 4.0 ml L-1) and two rhizobium inoculation levels (with rhizobium and without rhizobium). Chickpea variety RVG-203 was grown with the recommended agronomic practices. On the basis of results emanated from investigation it can be concluded that among the productivity parameters viz. maximum grain yield was 19.76 and 19.88 q ha-1 during the both years of experimentation are associated with the treatment T15 [60 kg P+ 4.0 ml-1 Chloropyriphos with Rhizobium]. Similarly stover yield during first year is 25.26 q ha-1 and second year is 25.94 q ha-1 was associated with the treatment T15 [60 kg P+ 4.0 ml-1 Chloropyriphos with Rhizobium]. Maximum gross return Rs 103908 and Rs 110078, net return Rs 66686 and 72232 and benefit cost ratio (B:C ratio) 1.79 and 1.91 during the first year (2020-21) and second year (2021-22) of experimentation were recorded under treatment T15 [60 kg P+ 4.0 ml-1 Chloropyriphos with Rhizobium], but the maximum cost of cultivation during first year is Rs 38734 and second year is Rs 39358 were recorded under treatment T18 [90 kg P+ 4.0 ml-1 Chloropyriphos with Rhizobium].
