Effect of phosphorus liquid bio-fertilizer on productivity and economics of chickpea (Cicer arietinum L.)

A field study was carried out during rabi season of 2017–18 at Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, Satna (M.P.) to evaluate the effect of phosphorus liquid bio-fertilizer on yield attributes, yield and economics of chickpea. Application of 40 kg P₂⁵/ha + PSB-II produced maximum grain yield (1425 kg/ha), better nodulation and yield attributes well as well highest gross returns ( 77728/ha), net returns of ( 59864/ha) and benefit: cost ratio of 4.34. The lowest grain yield, yield parameter and economics were found in untreated control plot. The treatment 40 kg P₂O₅/ha + PSB-II also saved 20 kg P₂O₅/ha as it gave statistically equal yield to use of 60 kg P₂O⁵/ha (1381 kg/ha grain yield).
