| dc.description.abstract | A field experiment was conducted at the Main Agricultural Research Station, College of Agriculture, University of Agricultural Sciences, Dharwad, Karnataka during kharif 2010- 11 to study the effect of organics on growth, morpho-physiological characters, biochemical parameters, yield and yield attributes of maize. The experiment was laid out in a randomised block design with 14 treatments replicated thrice. Treatments include different organic sources viz., FYM, vemicompost, sheep manure and poultry manure alone and combinations with inorganic sources were compared with control. The morpho-physiological characters viz., total dry matter production, plant height, number of leaves, leaf area and physiological parameters like leaf area index and leaf area duration were significantly higher with treatment poultry manure + 100% RDF at all the growth stages. While, the lowest morpho-physiological characters were observed in control. The growth indices like AGR CGR and NAR were significantly higher in the treatment poultry manure + 100% RDF, followed by sheep manure + 100% RDF at all the growth stages. While, lower growth indices were recorded in control. The biochemical parameters like chlorophyll content, leaf nitrogen content and nitrate reductase activity was higher in poultry manure + 100% RDF compared to other treatments. Significantly the higher grain yield of maize (90.2 q ha-1) was recorded in treatment poultry manure + 100% RDF followed by sheep manure + 100% RDF compared to other treatments. While, lowest yield was recorded in control. Similarly, higher harvest index, test weight and shelling percentage was recorded in poultry manure + 100% RDF, followed by sheep manure + 100% RDF and FYM + 100% RDF. The lowest yield and yield parameter was recorded in control. Different treatments had significant influence on economics. Significantly the highest B:C ratio (2.69) was recorded in RDF alone, followed by poultry manure + 100% RDF (2.55) and sheep manure + 100% RDF (2.38). | en_US |
