Abstract
The study was conducted to examine the maize residue practices and its impact on productivity, profitability on succeeding crop and farmers livelihood. A total of 60 farmers from Ghoraghat upazila of Dinajpur district were selected randomly for data collection. Descriptive statistics (i.e., sum, average, percentages, ratios, etc.), profitability analysis and logit model were employed to achieve the objectives. In case of pattern of maize residue retention, whole retention method was the highest and it was 78.2 percent. The whole retention of maize residue was found higher in far distance plots from homestead and it was 82.8 percent. The highest utilization of maize residue was identified as organic fertilizer and it was 82.2 percent. Due to maize residue practices, both crop and livestock were benefited through resource interdependences. The productivity, profitability and annual income of succeeding crop i.e., Aman rice were higher due to maize residue practicing. The result of logit regression model shows that the farm size, age of household head, farm income and non-farm income were found as significant variables in explaining the maize residue adoption. The access on human capital, social capital, financial capital, natural capital and physical capital were increased by 23.5, 22.7, 26.7, 10.6 and 18.8 percent, respectively due to the practice of maize residue in comparison to traditional farming. The study recommended that farmers could enhance their livelihood if they get proper training facilities and extension services for maize residue management.J. Bangladesh Agril.

Highlights
Bangladesh is a small developing country where most of the people earn their living from agriculture
This study concludes that retention of maize residue significantly increased yield and yield components of succeeding crop i.e., Aman rice
Due to maize residues practice, crop and livestock both were benefited through resource interdependences
Summary
Bangladesh is a small developing country where most of the people earn their living from agriculture. Maize is the third most important cereal crop in Bangladesh, after rice and wheat. It is a major cash crop, and is one of the major sources of employment, especially for smallholders and women. The developed countries are capable to deal with low soil fertility through supply of nutrients in sufficient amounts as chemical fertilizers. Crop residue plays an essential role in nutrient recycling to improve soil quality and ensure higher level of crop productivity. It can be composed by various methods on the farm itself and used there in the field for mulching. Crop residue management is the best alternative to increase the productivity with maintaining the soil quality
