Abstract
The cultivation of vegetables under organic management is perfomed most often with rotary tilling which mobilizes the soil very. One of the main problems of organic agriculture is to find alternatives for the supply of nutrients, particularly nitrogen, to production systems. One technique is of great value green manure, using primarily legumes are suitable and effective on the symbiosis with Rhizobium strains prevalent in each region. There are several patterns of use of green manure, the most common pre-cultivation of legumes as cover crops and subsequent incorporation into the soil preparation, in relation to soil management, no- tillage system has been considered one of the more sustainable ways of practicing agriculture. The use of alley cropping system provides additional benefits such as protection from winds, higher biodoversidade, increased flowering for pollination, and shelter for natural enemies. Research on scientific grounds for appropriate management of sustainable production systems with no-tillage, use of alley cropping, combined with crop rotation of winter vegetables and corn in summer, under organic management, not only provide greater profitability by area of cultivation and food security, but also maintenance of soil fertility.
