Alley cropping system is mainly for soil fertility improvement especially in the sloppy regions.Bangladesh is dominated by flatland and its potentiality has not been evaluated using vegetable crops. To address the issue of crop environment and crop productivity, the concepts like organic farming and regenerative agriculture alley cropping can play its role. This book emphasized the effect of tree species and alley widths on tomato production and soil nutrient at various nitrogen levels along with pruned materials. The design was split-split plot where three multipurpose tree species were arranged in main plots; three alley widths and five different doses of nitrogen were distributed to sub and sub-sub plots, respectively. In a control plot full dose of nitrogen was applied but no pruned materials (PM) were incorporated. Comparative growth performance of three multipurpose tree species, performance of tomato and changes in the soil fertility were observed. This book will be helpful for the wide range of professionals like academicians, researchers, policy makers, and social workers. This book will certainly widen the diversity of knowledge in crop productivity in sloppy region.
