An algorithm was developed for conventional implantation of sugarcane crap. In addition, a differentiated implantation was developed with the purpose of providing same production (tons), in subsequent years of the implantation. Since sugarcane productivities in the following years are different. However the new methodology is limited to the maximum planting area, and in some cases annual production falls due to impossibility to increase planted area. A third methodology was also developed, in which the area does not become a limiting factor, and therefore production remain constant. To evaluate the viability of proposed methods, calculations of the cost of crop implantation, of sugarcane maintenance, annual income and the net incomes were converted later to the Present Value. The results showed that in spite of the higher initial investment, the new methods always provide highest real profit abilities in the time course and that recovery time of the invested capital is also smaller. The algorithms were transformed in the software "canavial.exe", which can be assessed freely at site: "<A HREF="http://dl.winsite.com/bin/downl?500000027058">http://dl.winsite.com/bin/downl?500000027058</A>".
