A field experiment was conducted during winter season of 2021-22 at  the  Research Farm, AKS University, Satna  (MP) to study the effect of organic manures on  growth, yield and economics of onion (Allium cepa L.). Among the treatments, poultry  manure 7 t/ha + vermicompost 10 t/ha (T12) recorded significantly maximum plant height, leaves/plant, neck diameter, leaf area index and  crop growth rate (52.10 cm, 12.56/plant,  2.27 cm,  3.109 and  5.89 g/cm2/day, respectively)  at 120 DAT. While, maximum relative growth rate (49.20 g/g/day) and net assimilation rate (1.435 mg/cm2/day) at 30 DAT in T12 was noted. T12  (poultry  manure 7 t/ha + vermicompost 10 t/ha) also recorded the higher diameter and length of bulb (6.62 and 7.90 cm, respectively), bulb yield (42.31 t/ha) and net income (Rs 90282/ha) with 2.89 B:C ratio from onion var Agrifound Light Red.

Keywords    Onion, organic manures, vermicompost, poultry manure, yield.
