Potentiality of Organic Rice Production Fertilized with Different Agroforestry Tree Leaf Litter in Northern Bangladesh

This paper provides information on eco friendly rice production using tree leaf biomass as a source of organic fertilizer. The experiment was conducted in Agroforestry Research Farm, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh to evaluate the response of different leaf litter biomass of different agroforestry species on the yield of rice (BRRI DHAN 49). The experiment includes 10 different treatments i.e. T0 (recommended doses of chemical fertilizer), T1 (100 g of Albizia), T2 (200 g of Albizia), T3 (300 g of Albizia), T4 (100 g of Leucaena), T5 (200 g of Leucaena), T6 (300 g of Leucaena), T7 (100 g of Melia), T8 (200 g of Melia) and T9 (300 g of Melia). The experiment was conducted following Randomized Complete Block Design (RCBD) with three replications. The result of the experiment revealed that, highest yield (5.66 tha-1) was recorded in T0 (recommended doses of chemical fertilizer). Among the treatments with leaf biomass, maximum yield was recorded in T3 (300 g of Albizia) 5.23 tha-1 followed by 5.04 tha-1 in T6 (300 g of Leucaena). Although, the yield was maximum with inorganic fertilizer but rice can be cultivated successfully with leaf biomass as a low cost environment friendly sustainable production system.
