The beans (Phaseolus vulgaris L.) has great economic importance in Brazil, as well as being a staple food of the population has high added value. Climate instability affects the bean in almost all producing regions of Brazil, causing large fluctuation in domestic production and making use of the very timely irrigation. In this context soil moisture is very important in controlling irrigation in the management of crop residues on the surface is effective in reducing soil water loss. The objective of this study was to evaluate the influence of the management of crop residues from the soil surface (with and without incorporation) in the use of irrigation water through the evaluation of soil moisture and evaluate the development and productivity of bean under one irrigation management. The project was conducted in the White Bullock Stream watershed, included in the municipalities of Paranapanema and Itai, in the southwestern region of the State of São Paulo. The predominant soil in the region is very clayey oxisol. The irrigation system used was the central pivot and is adopted minimum tillage system with conservation of straw on ...
