A field experiment was carried out at Main Agricultural Research Station, Dharwad during Kharif, 2010 and 2011 to study the nutrient management practices for organic cotton production. The results of the two years pooled data revealed that, among the treatment combinations, integrated application of RDF + FYM and green leaf manure as mulch with application of jeevamrutha @ 500 l/ha recorded significantly higher number of bolls per plant (41.37), mean boll weight (5.05 g), kapas weight per plant (116.88 g), kapas yield (1858 kg/ha) over other treatments. Among the organic combinations application of compost (50%) + vermicompost (50%) equivalent to RDF + green leaf manure as mulch with application of jeevamrutha @ 500 l/ha recorded higher number of bolls per plant at 150DAS, mean boll weight, kapas weight per plant, kapas yield , net returns and B:C ratio and was at par with RDF + FYM and which was superior over RDF only. Among the nutrient management practices, application of FYM @ 5t per ha + RDF recorded significantly higher number of bolls per plant (40.13) at 150DAS, mean boll weight (4.87 g), kapas weight per plant (114.69), kapas yield (1777 kg/ha), net returns (Rs. 53530) and B:C ratio (2.67) over rest of the treatments. Among the organic manurial treatments, combined application of compost (50%) + vermicompost (50%) equivalent to RDF recorded significantly higher number of bolls per plant (36.53), mean boll weight (4.42 g), kapas weight per plant (107.96) and kapas yield (1579 kg/ha) over other organic manurial treatments but was at par with crop residue (50%) + vermicompost (50%) equivalent to RDF. However, crop residue (50%) + vermicompost (50%) equivalent to RDF recorded significantly higher net returns (57220) and B:C ratio (2.80) over other organic manurial treatments. Among the green manuring treatments, application of green leaf manure (GLM) @ 7.5 t per ha with jeevamrutha @ 500 l/ha surface applied recorded significantly higher number of bolls per plant (36.51), mean boll weight (4.46 g), kapas weight (109.08 g), kapas yield (1621 kg/ha), net returns (Rs. 55890) and B:C ratio (2.70) over other green manuring treatments and was at par with lucerene + jeevamrutha.Keywords

The present investigation was undertaken during Kharif 2011 at University of Agricultural Sciences, Dharwad to know the response of organic nutrient management practices on yield and nutrient uptake of aerobic rice. The experiment was laid out in Split Plot Design with 2 main plot treatments, 8 sub plot treatments and 2 controls. The main plot treatments comprised of M1-EC (1/3)+VC (1/3)+GLM (1/3) equivalent RDNand M2-EC (1/3)+VC (1/3)+GLM (1/3) equivalent to RDF + FYM, sub plot treatment comprised of L1-bio-digester @ 500 l ha-1 applied at planting, 30 and 60 DAS applied to soil, L2-jeevamrut @ 500 l ha-1 applied at planting, 30 and 60 DAS applied to soil, L3-Panchagavya @ 5 per cent foliar application at panicle emergence and flowering stages, L4-cow urine @ 10 per cent foliar application at panicle emergence and flowering stages, L5-L1+ Panchagavya @ 5 per cent foliar application at panicle emergence and flowering stages, L6-L1+ cow urine @ 10 per cent foliar application at panicle emergence and flowering stages, L7-L2+Panchagavya spray @ 5 per cent at panicle emergence and flowering stages and L8-L2 + cow urine @ 10 per cent foliar application at panicle emergence and flowering stages and two controls were RDF only and RDF + FYM. Application of different organic manures significantly increased the yield and nutrient uptake of aerobic rice. The Results revealed that integrated application of M2- EC (1/3)+VC (1/3)+GLM (1/3) equivalent to RDF+FYM with soil application of jeevamrut @ 500 l ha-1 at planting, 30 and 60 DAS+Panchagavya foliar application @ 5 per cent at panicle emergence and flowering stages recorded significantly higher grain yield (3837 kg ha-1) and straw yield (5855 kg ha-1) with higher nutrients uptake.Keywords
