COMPARATIVE STUDY ON THE GROWTH OF COMMON BEAN (PHASEOLUS VULGARIS) UNDER NPK FERTILIZER AND CHICKEN DUNG

Abstract This project investigates the competitive growth dynamics of common beans (Phaseolusvulgaris) under various environmental and agronomic conditions. Common beans are a crucial food crop, providing a significant protein source, especially in developing regions. However, competition among bean plants and with other crops can affect yield and quality. This study examines factors influencing bean growth, including plant density, nutrient availability, water access, and competition from other species. Field trials and controlled experiments were conducted to evaluate how different planting densities and nutrient levels impact growth rates, biomass accumulation, and yield. Results indicate that optimal plant spacing and adequate fertilization significantly improve growth outcomes, while overcrowding and nutrient deficiencies reduce productivity. Additionally, intercropping practices were assessed to understand how companion plants affect bean growth through competition for light, water, and nutrients. Findings provide insights into effective cultivation practices to maximize bean productivity in competitive agricultural environments. These recommendations aim to support sustainable agriculture by optimizing resource use and improving food security.
