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 field experiment was carried out at MARS, Dharwad during Kharif 2010-11 and 2011-12 to study the effect of organic farming practices on soil properties and beneficial soil micro-organism among the organic manurial treatments, application of EC (1/3) + VC (1/3) + gliricidia GLM (1/3) equivalent to RDF recorded significantly higher uptake of N, P2O5 and K2O (72.53, 14.26 and 77.3 kg ha-1, respectively) over EC (1/3) + VC (1/3) + GLM (1/3) equivalent to RDN. Among the organic treatment combinations, application of EC (1/3) + VC (1/3) + gliricidia GLM (1/3) equivalent to RDF with foliar spray of Panchagavya @ 5 per cent recorded significantly higher uptake of N, P2O5 and K2O (73.80, 15.16 and 78.4 kg ha-1, respectively) over other organic combinations and was at par with (1/3) + VC (1/3) + GLM (1/3) equivalent to RDF with borax @ 0.2 per cent + MgSO4 @ 1 per cent and RDF + FYM. Among the nutrient management practices, integrated application of EC (1/3) + VC (1/3) + gliricidia GLM (1/3) equivalent to RDF recorded significantly higher available soil N, P2O5 and K2O (282.5, 28.8, 328.3 kg ha-1, respectively) over FYM @ 5 t ha-1). + RDF. Combined application of EC (1/3) + VC (1/3) + GLM (1/3) equivalent to RDF and EC (1/3) + VC (1/3) + GLM (1/3) equivalent to RDN recorded significantly higher organic carbon (5.6 and 5.5 g kg-1). respectively) over FYM @ 5 t ha-1 + RDF (5.2 g kg-1). Integrated application of EC (1/3) + VC (1/3) + gliricidia GLM (1/3) equivalent to RDF recorded significantly higher bacteria, fungal, actinomycetes, phosphorus solubilising bacteria, N2-fixers, enzymes mainly phosphatase and dehydrogenase activity and soil respiration rate (73.19 cfu × 106/ g of soil, 26.84 cfu × 103/ g of soil, 39.65 cfu × 102/ g of soil, 26.15 cfu × 103/ g of soil, 29.52 cfu × 103/ g of soil, 25.01μ pnp/g of soil/hr, 11.99 μ TPF/g of soil/day and 9.51 mg of C or CO2/hr/100 g of soil, respectively) at 60 DAS as compared to application of FYM @ 5 t ha-1 + RDF. Among the different treatment combinations, application of EC (1/3) + VC (1/3) + gliricidia GLM (1/3) equivalent to RDF with foliar spray of Panchagavya @ 5 per cent recorded significantly higher bacteria, fungi, actinomycetes, N2-fixers and P-solubilizer, phosphatase and dehydrogenase enzyme activity and soil respiration rate over RDF + FYM.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

Investigations were carried out to study the effect of organics on yield and fruit quality parameters in bell pepper grown under open condition. Split plot design, with three replications, was adopted taking two bell pepper varieties, viz., California Wonder and Gangavati Local (as main-plot treatments) and nutrient source (as sub-plot treatments). Variety California Wonder performed better with respect to yield parameters compared to the Local variety. Application of 100% recommended dose of nitrogen (RDN) through a combination of 50% FYM and 50% poultry manure (O5) as basal dose recorded significantly higher fruit yield (16.33 t/ha) and yield components over other treatments. Among interactions, O5 (FYM (50%) + poultry manure (50%) recorded significantly higher fruit yield (18.47 t/ha), followed by 18.31 t/ha with organic application in O1 (FYM (50%) + Vermicompost (50%) in California Wonder variety.Keywords
