An Insight into the Physico-chemical Properties of Soil under Rice-based Cropping Systems

An experiment was conducted with seven cropping systems T1 (Rice – Rice), T2 (Rice – (Green gram / Black gram), T3 (Rice - Cotton), T4 (Rice – Sesame), T5 (Rice – Maize), T6 (Rice – Dhaincha), T7 (Rice – Rice – Rice) during the rabi season (October to January), 2021-2022. At the post-harvest stage, samples were collected from several cropping systems in the experimental plot. In the Department of Soil Science and Agricultural Chemistry, Coimbatore, Tamil Nadu, India, cropping systems were examined for physico-chemical analysis. Cropping systems differed in physicochemical properties as a result of soil variance. Rice - (green gram/black gram) has better nutrient status than other farming systems. Rice-rice-rice was found to have lower nutrient status.
