摘要：Mangifera indica, Zizyphus jujuba, Litchi chinensis, and Artocarpus heterophyllus are the most common cropland agroforest horticultural tree species of Bangladesh. This study focused on leaf litter decomposition and nutrient (N, P, and K) dynamics during the decomposition process. This experiment was conducted for 180 days by using litter bag technique during dry and wet seasons. Mass loss was the highest (49% and 57%) for A. heterophyllus and the lowest (25%) was found for L. chinensis. The highest initial rates (0.75% and 2.35%/day) of decomposition were observed for Z. jujuba and the lowest (0.50% and 0.79%/day) for L. chinensis. The highest decay constant was observed for A. heterophyllus (2.14 and 2.34) and the lowest (0.88 and 0.94) for L. chinensis. Leaf litter of all the studied species showed a similar pattern (K > N > P) of nutrient release during the decomposition process. Zizyphus jujuba showed comparatively higher return of N, P, and K than others. However, a significant () higher amount of mass loss, rate of decomposition, decay constant, and amount of nutrient return from leaf litter were observed during the wet season.
