| dc.description.abstract | A field experiment was conducted to study the ^'Response of cotton genotypes to different sources of organic manures under organic production system" at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad during 2004-05. The experiment was laid out in split plot design with varieties as main plots and organic nutrient management treatments as sub plots with three replications. Bio-pesticides were used as combative measures against pest and diseases. Among the varieties evaluated under organic production system, Jayadhar recorded significantly higher (TDMP) (137.50 g/plant) and drymatter accumulation in leaves (17.66 g/plant), stem (85.50 g/plant) and squares (4.82 g/plant) as compared to Sahana. Jayadhar also recorded significantly higher LAI (0.54 dm/m^), number of monopodial and sympodial branches (5.10 and 14.75/plant) and number of bolls (36.38/plant) at 180 DAS as compared to Sahana. Kapas yield (1 172 kg/ha), net return (Rs,10,992/-) and B:C ratio (2:2) were also significantly higher with Jayadhar. Sahana recorded significantly higher fibre length, fibre fineness, fibre strength and maturity ratio as compared to Jayadhar. Among manorial treatments, integrated application of RDF (40:25:25 N, P2O5, K2O kg/ha) with FYM 7.5 t/ha recorded significantly higher TDMP production (142.16 g/plant), plant height (108.33 cm), leaf weight (18.74.g/plant), stem weight (83.54 g/plant), boll weight (39.10), number of monopodial and sympodial branches (4.33 and 15.56/plant) and number of green bolls (30.05/plant) at 180 DAS as compared to rest of the treatment. Seed cotton yield (1142.35 kg/ha) was also higher with integrated manurial treatment. However, there was no significant difference with respect to quality parameter among all the treatments. Organic manurial treatments, FYM and VC equivalent to 100% RDN, FYM 100% + VC 100%, FYM 100% + glyricidia 100%, FYM 100%+ VC 50% + neem cake 50%, FYM 100% + glyricidia 50% + neem cake 50%, FYM 50%+ glyricidia 50%, FYM 50%+ VC 25%+ neem cake 25% and FYM 50%+ glyricidia 25%+ neem cake 25% were found on par with that of RDF (40:25:25 N, P2O5, K2O kg/ha). Integrated manurial treatment (RDF+FYM) recorded significantly higher N, P2O5 and K2O content after harvest of the crop (264.27, 34.22 and 480.97 kg/ha NPK). Organic carbon content In soil was higher with RDF + FYM and FYM 100% + glyricidia 100% and also recorded significantly higher population of bacterial, fungal and actinomycetes. | en_US |
