Abstract

This experiment was carried out in the field at the Estação Experimental de Zootecnia de Colina, State of São Paulo, Brazil, with objective studied that the residual mineral nitrogen fertilization and biological nitrogen fixed by forage legumes effect of sorghum with rotation culture. The sorghum was sown in the plots before cultivated during three years with perennial soybean, cudzu, centro and colonião grass. The grass, as well as the legumes, had been fertilized with three levels of nitrogen (0, 150 and 300 kilogram per hectare per year) or mixed with the legumes. A control plot was added. The nitrogen biologically incorporated by the legumes resulted in the increases in the dry matter and protein production. The dry matter and protein production of sorghum in the plots with exclusive legume, legume with 150kg N/ha, legume with 300 kg N/ha, legume mixed colonião, colonião with 0, 150 and 300 kg N/ha and control were: 11.693 and 649; 8.223 and 451; 3.907 and 199; 7.200 and 380; 4.730 and 246; 9.730 and 610 kg/ha/ano, respectively.
