DEVELOPMENT AND PRODUCTIVITY OF BEAN ON DIFFERENT DOSAGES OF PHOSPHATE DUBBING

Abstract

The bean crop has a relatively short cycle with a vegetative development speed of 90 days, making the bean plant very sensitive to the risks of low productivity in the field, which can increase production costs. The national productivity average is still considered low, since the productive potential of the crop under appropriate conditions can reach values ​​above 4,000 kg ha-1. Achieving maximum productivity is increasingly important, making it necessary to use phosphorus fertilizer judiciously, with high levels of uniformity and efficiency in use. To meet these requirements, concern with the quality of fertilization is necessary, maximizing the maximum use of phosphates, transforming them into productivity, since the low availability of phosphorus in the soil affects the growth and production of bean plants. The objective of this work is to evaluate the plant growth and effectiveness of the applications of phosphorus fertilization at different doses on the development and productivity of beans in its various stages. Plants with the highest doses of phosphate fertilizer had faster growth, while those with lower doses had reduced growth as a response, since the plants that were not fertilized had low development or even none. Therefore, phosphorus fertilization is considered essential in bean cultivation.
