| Abstract | This study was conducted in the Chandina sub-district, Bangladesh to find out soil fertility and land productivity status in common cropping systems and in different land types in order to identify suitable cropping systems for specific land types. Ten common cropping systems from four different land types were selected for the present study using primary and secondary data. Cropping systems are dominated by potato, rice, bitter gourd, long bean, okra and cauliflower. The soil characteristics of the study area are moderately acidic in highlands and medium highlands, and moderately acidic to weakly acidic in medium lowlands and lowlands. Organic matter and nitrogen contents were low to medium, while phosphorus was medium to very high, potassium and zinc contents were low to high and sulfur content was medium to very high. Potato/rice-rice-rice cropping system showed the highest land productivity index compared to other cropping systems in highlands, while both in medium highlands, medium lowlands and lowlands rice-rice-rice cropping system gave the highest land productivity index. Land productivity index confirmed that potato/rice-rice-rice was suitable for highlands, while rice-rice-rice cropping system was suitable for both medium highlands, medium lowlands and lowlands. These findings confirm the farmers' selection of cropping systems for their croplands are justifiable for maintaining the soil fertility and land productivity. |
