The citrus industry is one of the most important agricultural activities in Brazil, and ranks 2nd in the world production (8 million metric tons) and 1 st in concentrated juice export (400 thousand tons). The citrus area (located between 0grau and 30graus south latitude) is calculated at more than 600 thousand ha, with aproximately 150 million trees. One of the most important point to consider is the fact that about 95% of the citrus trees are grafted on Rangpur lime. Taking into account the excellent performance of this rootstock, its almost exclusive use implies some risks since the occurrence of a very serious disease could cause the collapse of the citrus industry similar to that which occurred in 1939-40 with tristeza. Rootstock trials carried out in different citrus areas have shown that a successful rootstock diversification program can be established by the use of other rootstocks besides the Rangpur lime, like Florida and FM rough lemons (C. jambhiri Lush.), C volkameriana pasq. Cleopatra (C. reshni Hort. ex Tan.) and Sunki (C. sunki Hort. ex Tan.) mandarins and others with promising rootstock characteristics. |

The combination of soil science, forestry, agronomy and biology allowed an analytical comparison of various experimental mixed culture systems. From these studies, a descriptor system was developed which allows to understand the contribution of each plant species to nutrient cycling, water distribution, litter formation, overall biomass production and crop production. This knowledge allows to combine plants so that their properties interact to form a system, which minimizes mineral losses and which regulates air humidity and water distribution and thus leads to stable crop production. The general conclusion which can be drawn after eight years of polyculture study is: a) stable productions systems for samllholder families have bee developed; b) the systems are variable; they can be adapted to the respective site conditions; c) the manager of these plantations requires a deeper understanding of the cultivation systems and an intensive dissemination of knowledge and a well develope on-farm training system for farmers. |
