Abstract

The experiment has twenty four treatment combinations comprising of six main plots, organic manures mainly green leaf manure (GLM), enriched compost, FYM and vermicompost in combinations compared with RDF and FYM + RDF and four sub plots, liquid organic manures mainly bio-digester liquid manure, Panchagavya and cow-urine. The treatments comprised of application of 7.5 t FYM + RDF (100:50:25 N, P₂O₅, K₂O kg ha^-1 + 10 kg ZnSO₄) (RPP) and (100:50:25 N, P₂O₅, K₂O kg ha^-1 + 10 kg ZnSO₄) (RDF) alone exhibited significant effects on yield of sweet corn viz., with husk and without husk cob weight per plant, fresh cob yield, fresh and dry grain weight per plant and quality parameters viz., protein content, reducing and non-reducing sugar, total sugar, total soluble solids and total carbohydrates content in sweet corn kernels of sweet corn. Among the organic manurial combinations GLM + EC + VC (top dressing at GGS) recorded higher yield and quality of sweet corn with all liquid organic manures over basal applied vermicompost. Similarly, bio-digester and cow urine @ 10 per cent spray noticed higher yield and quality of sweet corn over control. Irrespective of organic manures, the dehydrogenase activity were significantly higher with GLM + FYM + VC (top dressing at GGS) and GLM + EC + VC (basal) equivalent to RDN over RPP and RDF.

Abstract

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 nutrient uptake and fertility status of soil. The experiment has twenty four treatment combinations comprising of organic manures mainly green leaf manure (GLM), enriched compost, FYM and vermicompost and liquid organic manures mainly bio-digester liquid manure, Panchagavya and cow-urine. Irrespective of liquid organic manures, the nutrient uptake and fertility status of soil viz., N, P and K content and uptake, available nitrogen, phosphorus and potassium status 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. Similarly, organic carbon and micronutrients (viz., Cu, Zn, Mn and Fe content) were significantly higher with application of organic manurial treatments over RDF and RPP. Among the organic manurial treatment combinations GLM + EC + VC (top dressing at GGS) was significantly superior over basal applied vermicompost.
