|A field experiment was carried out at ZARS, Brahmavar, UAS, Bengaluru during Kharif , 2012. The experiment was laid out in randomized complete block design with eleven treatments replicated thrice. The treatments consisted of combinations of organic manure (glyricidia, euphotorium, poultry manure, vermicompost, and goat manure) and liquid organic manure (cattle urine and bio digester liquid manure) and these treatments were compared with recommended dose of fertilizer. Application of 50 per cent recommended dose of nitrogen through goat manure + 50 per cent N through bio digester liquid manure produced significantly higher grain yield (5110 kg ha -1 ) and straw yield of rice (6105 kg ha -1 ) as compared to other combinations of organic manure + liquid organic manure and recommended dose of fertilizer (4351 kg ha -1 and 4974 kg ha -1 respectively). This was mainly due to growth attributing parameters like plant height (95.47 cm), number of leaves (115.61), number of tillers (44.35), leaf area (1481.16 cm 2 ), total dry matter production per hill (118.92 g) and yield contributing characters like number of productive tillers per hill (34.69), panicle weight (5.75 g), 1000 grain weight (25.70 g) and number of filled grains per panicle (141.12). The total nutrient uptake of nitrogen, phosphorus and potassium (129.47, 32.87 and 100.86 kg ha -1 , respectively) and higher population of bacteria, fungi and actinomycetes (51.22 cfu X 10 6 g -1 of soil, 62.45 cfu 10 3 g -1 of soil and 38.98 cfu 10 3 g -1 of soil) were recorded in the same treatment.|
M Padmanabhan born and brought up in Mysore, Karnataka completed his school and college education in Mysore. He then completed his BSc (Agriculture) during 2011 and his M.Sc. (Agriculture) in Agronomy during 2013 from University of Agricultural Sciences, GKVK, Bengaluru. He conducted his research on Effect of different organic manures on growth and yield of transplanted rice for his Masters degree. He has published two research papers, four research abstracts and two popular articles in reputed journals and magazines. He has also participated in two national level conferences.
