Umidade do solo e produção da cultura de feijão
| Resumo: | The common bean (Phaseolus vulgaris L.) is an important food for the population. The demand for this product in any country is high, which promotes sharp fluctuations in price depending on their offer, featuring the great socioeconomic importance ssociated with this culture. The knowledge accumulated from several studies indicates that the bean is sensitive to drought and soil conditions among these, the supply of water during the cycle, sufficient to ensure perspiration without restrictions, as well as the structure of the soil which should not to be a mechanical constraint to root development. These are characteristics which presents a strong impact on the development and production of this crop. However, the identification of a structural condition associated with the water content of soil, which causes restriction to the culture remains uncertain. Thus, it becomes necessary to investigate bean response to different levels of water supply and soil density. Thus, it is necessary understand relationships between them. An experiment was conducted in the greenhouse Irrigation Training Center at the State University of Maringá, in a completely randomized design with four replicates in the 5x5 factorial design. It was analyzed relative grain production, relative irrigation depth and water using efficiency. The results show that the bean responds sensitively to the variation of soil moisture, as well as the different structural conditions in development and production. |
