Abstract

A field experiment was conducted for two consecutive years to study the impact of weather on performance of chickpea (Cicer arietinum L.) with organic manures and various levels of rock phosphate with PSB grown in vertisol of northern dry zone of Karnataka, at Agricultural Research Station, Annigeri, UAS, Dharwad, Karnataka during Rabi season of 2009-10 and 2010-11.The experiment was laid out in RCBD with three replications. There were nine treatment combinations consisting of two organic manures viz., compost and FYM with four levels of rock phosphate (50, 100, 150 and 200 kg ha^-1) and an absolute control treatment for comparison. In both the years 2009-10 and 2010- 11 the yield attributing parameters like number of pods per plant(67.76), number of seeds per pod(1.12), test weight(20.71gram), grain yield (2130 kg/ha) and halum yield (3300 kg/ha) were recorded with the treatment combination of compost 5 t along with rock phosphate 200 kg / ha compared to other treatment combination and absolute control.

Abstract

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.
