Abstract:
A field study was conducted during Kharif 2021 at Research Institute of Organic Farming (RIOF) field unit, University of Agricultural Sciences, Bangalore to examine the response of grain amaranth (Amaranthus hypochondriacus L.) to different organic sources of nutrients. Among all the organic sources of nutrients Growth attributes like Plant height (165.7, 159.8,147.6and 115.0 cm), No. of leaves per plant (26.3, 25.5,24.1and 19.2), Leaf area per plant (2436, 2211, 2079and 1078 cm²) and total dry matter accumulation per plant (71.1, 66.9,58.5 and 40.8 g plant^-1) and yield attributes like Panicle length (54.33, 52.33,48.50 and 38.33 cm), No. of fingers per panicle (37.67, 37.0, 35.67 and 25.33) and length of finger (22.13, 21.0, 20.37 and 15.30 cm), Grain yield (2127,2105,1972 and 1428 kg ha^-1), Stover yield (3596,3525,3417 and 2810 kg ha^-1) were recorded significantly higher with the application of 50% N equivalent FYM+ 50% N equivalent PC and which was found to be on par with application of 50%N equivalent PC + 50% N equivalent BDLM and 50% N equivalent PC + microbial consortium soil application. However Lower growth and yield attributes were recorded in Absolute control. Whereas, Higher Net returns and B:C ratio (89511 Rs. ha^-1and 2.43) were observed with the application of 50%N equivalent PC + 50% N equivalent BDLM.
