摘要

Millets are climate-resilient crops that alleviate malnutrition and improve food security in several developing countries. Although sporadic reports on the nutritional aspects of millets are available, comprehensive data on the effects of millet cultivation on soil health in rainfed calcareous Vertisol has not yet been studied. With this research gap, this work was conducted to evaluate the effects of growing major and minor millets on soil nutrient availability and biological properties. Millet cultivation significantly decreased soil pH (2.6-7.6%), indicating soil acidification. Significant enhancements in soil organic carbon (18-57%), mineralizable nitrogen (48-104%), available phosphorus (92-180%), and available boron (133-300%) were observed in millet plots compared with the no crop treatment. In soil biological attributes, millet cultivation significantly increased glomalin (13-67%) and soil polysaccharide (122-211%) contents. Overall, minor millets provide greater soil health benefits in terms of soil nutrient availability and biological properties than major millets.
