A field experiment was carried out during kharif 2009-10 at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad to find out the influence of organic nutrients on growth and yield parameters and yield of sweet corn. The experiment has twenty four treatment combinations comprising of organic manures mainly green leaf manure (GLM), enriched compost (EC), FYM and vermicompost (VC) and liquid organic manures mainly bio-digester liquid manure, panchagavya and cow-urine. Irrespective of liquid organic manures, the growth parameters of sweet corn viz., plant height, number of green leaves, leaf area, leaf area index and total dry matter production were significantly higher with 7.5 t FYM + RDF (100:50:25 N, P2O5, K2O kg ha-1 + 10 kg ZnSO4 (RPP) and RDF alone as compared to nutrient substitution through organic manures. Among the organic manurial combinations GLM + EC + VC (top dressing at GGS) recorded higher yield with all liquid organic manures over basal applied vermicompost. Similarly, yield and yield attributes mainly number of cobs per plant, cob length, cob girth, number of grains per cob, fresh and dry grain weight per plant and fresh cob yield per ha were also significantly higher with treatments supplemented with RPP and RDF alone. Among the organic manurial treatment combinations GLM + EC + VC (top dressing at GGS) was significantly superior over basal applied vermicompost. Among the liquid organic manures, bio-digester liquid noticed higher yield and yield attributes of sweet corn over control and was on par with panchagavya and cow urine foliar application.
