Growth and Yield of Rice (Oryza sativa) as Influenced by Humic Acid and Poultry Manure

Humic acid (HA) and poultry manure (PM) were applied on T. aman rice cv. BRRI dhan39 to observe their effects on rice. Three levels of humic acid viz. 0, 3 and 6 L ha -1 and three levels of poultry manure viz. 0, 3 and 6 t ha -1 were applied along with recommended doses of N, P, K and S fertilizers from urea, TSP, MoP and gypsum, respectively following Randomized Complete Block Design (RCBD). Parameters used in the experiment were plant height, effective tillers hill -1 , panicle length, no. of grains panicle -1 , 1000-grain weight, grain and straw yields. The application of different treatments showed positive trend in all the parameters of BRRI dhan39. The highest grain yield (4.07 t ha -1 ) was recorded by the application of 6 L ha -1 humic acid along with 3 t ha -1 poultry manure which was identical with the application of 6 L ha -1 humic acid along with 6 t ha -1
