The present field experiment has conducted during the autumn season of 2019-20 at the crop research farm of Department of Soil Science & Agriculture Chemistry, SHUATS, Prayagraj, (UP). The aim of study to evaluate the effect of different organic manures on growth parameters, yield, yield component and economics of autumn Maize (Zea mays L.). The experiment consisted of 9 treatments in randomized block design with three replications consisted of T1: FYM @ 5 t ha-1, T2: FYM @ 10 t ha-1, T3: FYM @ 15 t ha-1, T4: VC @ 5 t ha-1,T5: VC @ 10 t ha-1, T6: VC @ 15 t ha-1, T7: BK @ 5 t ha-1,T8: BK @ 10 t ha-1, T9: BK @ 15 t ha-1. On the basis of the results emanated from present investigation, it could be concluded that application of vermicompost @ 15 tonnes ha-1 shows higher values in terms of growth parameter i.e. plant height (261.63 cm at 90 DAS), dry matter accumulation (177.56 g), cob length (20.82 cm) and cob girth (17.39 cm) and yield component i.e. number of filled cob plant-1 (2.33), number of grains cob-1 (442.88), number of grain row cob-1 (36.99), average cob weight (261.55 g) and test weight (220.53 g). Results also showed that application of vermicompost @ 15 tonnes ha-1 significantly enhanced productivity parameter i.e. Grain yield (3544.33 kg ha-1), green fodder yield (9810.67 kg ha-1), biological yield (13355 kg ha-1) and harvest index (26.54 %) followed by Bokashi Manures @ 15 tonnes ha-1. Higher values of economics viz., gross return ( 167915.9 ha-1), net return ( 333875.9 ha-1) and B:C ratio in maize was observed with the application of vermicompost @15 tonnes ha-1 except cost of cultivation.
