Abstract
Chemical fertilizers integrated with organic manures have proven as a better fertilizer management option for continuous crop productivity and improved soil fertility. An experiment was conducted to observe the growth and yield performances of transplanted aman rice as influenced by different organic manures under reduced chemical fertilizers conditions. The experiment consisted of eight treatments viz. ½ NPK (recommended dose of NPK for rice), full NPK, green manure (GM) + ½ NPK, poultry manure (PM) + ½ NPK, cowdung (CD) + ½ NPK, quick compost (QC) + ½ NPK, vermicompost (VC) + ½ NPK, magic growth (MG) + ½ NPK. This study was carried out in a randomized complete block design (RCBD) with three replications. Plant morphological characters, yield and different yield contributing traits were significantly influenced in different treatments. It was observed that, except for the total dry matter production and effective tiller hill-1, plant height, number of filled grain panicle-1, grain and straw yield were the highest with the treatment VC + ½ NPK. In our study, panicle length and 1000-grain weight of rice were also found to be the highest in VC + ½ NPK treatment, which was statistically similar with other ½ NPK + manure treatments. In overall observation, manure integrated treatments performed well compared to ½ NPK fertilization. Better performances were documented when VC was used in combination followed by QC and GM compared to ½ NPK fertilization.
