Role of Leguminous Crops in Enhancing Soil Fertility and Their Impact on the Growth and Yield of Companion Crops

Abstract

The importance of legume crops in improving soil fertility through nitrogen fixation is examined in this study, as is their subsequent impact on companion crop growth and productivity. Legumes are essential for turning atmospheric nitrogen into a form that plants can use because they have nitrogen-fixing bacteria in their root nodules. An environment that is more fertile for plant growth is created by the symbiotic association between legumes and nitrogen-fixing bacteria, which raises soil nitrogen levels. Assessing the effects of leguminous crops, including peas and soybeans, on soil nitrogen concentration and its relationship to the growth and yield of related non-leguminous crops is the goal of the study. The goal of the project is to measure legume    nitrogen contribution and comprehend how legume nitrogen affects companion crop nutrient availability through field experiments and soil sample analysis. Practices in sustainable agriculture depend on an understanding of these interconnections. Leguminous crops have a natural ability to fix nitrogen, so farmers can lessen their dependency on synthetic fertilizers by strategically adding them into their rotations. This helps to save costs and encourages farming methods that are favorable to the environment. The present review attempts to illuminate the complex interplay of leguminous crops, nitrogen fixation, and their influence on soil fertility. By utilizing the natural nitrogen-fixing capacity of leguminous crops, the research aims to offer insightful information for improving crop rotations and agricultural sustainability.
