Abstract
A field experiment entitled “Effect of Liquid organic manures on the performance
of Sweet Corn” was conducted during rabi, 2022-23 at Agricultural College Farm,
Naira to evaluate the performance of different liquid organic manures at various
nutrient levels. The experiment was laid out in Split-plot design in which different
fertilizer levels are taken in main plots and different liquid organic manures are
taken on subplots to assess the performance of sweet corn.
The treatment with the application of 100% RDF +FYM recorded the significantly higher
yield parameters and yield compared to other treatments and among the liquid organic
manures, significantly higher yield parameters are recorded with application of
liquid Azospirillum + Phosphorus solubilizing bacteria + Potassium releasing bacteria
+ Zinc solubilizing bacteria@ 1.25 l ha-1 which was at par with application of drava
Jeevamrutham spraying twice @ 10%. Significantly higher returns and B:C ratio were
recorded with 100% recommended dose of fertilizer +Farm yard manure in mainplots
and the liquid Azospirillum+PSB+KRB+ZnSB@ 1.25 l ha-1 has recorded significantly
higher returns.
