摘要

Declining soil fertility and ongoing land degradation from traditional shifting cultivation pose significant challenges to sustainable agriculture in the upland regions of Northeast India. This study provides a comparative analysis of soil nutrient dynamics and crop productivity under Jhum cultivation and integrated farming systems in three villages of Mamit District, Mizoram. Soil samples were collected during pre-monsoon and post-monsoon periods and analyzed for pH, organic carbon, nitrogen, phosphorus, and potassium. Statistical analyses, including analysis of variance and principal component analysis, were employed to assess differences in soil quality. A Soil Quality Index was also developed to enable comprehensive system comparisons. Results indicate that integrated farming system (IFS)-soil quality managed plots consistently maintained higher values compared to Jhum plots, as well as significantly higher Soil Quality Index scores, especially in the post-monsoon period. In contrast, Jhum fields exhibited pronounced nutrient depletion and reduced soil quality after cropping cycles. Principal component analysis further distinguished the two systems, linking the IFS to greater soil fertility stability. Crop yield data reinforced these findings, with notably higher yields of paddy, chili, and pumpkin under IFS. This study highlights the ecological and agricultural advantages of adopting integrated farming over traditional Jhum practices. It recommends expanding IFS adoption through targeted capacity building, infrastructural support, and participatory extension services. These insights provide an essential foundation for formulating sustainable land management policies aimed at improving food security and environmental resilience in fragile hill ecosystems.
