Abstract (AB)Field trials were laid down at four locations in Mauritius from 2003 to 2006 to determine the contribution of LGM to the N nutrition of sugarcane and whether LGM could partly substitute for mineral fertilizer N. Data showed that N returns to soil from LGM crops ranged between 100 and 267 kg N/ha of which 50 to 70 per cent was obtained from biological fixation. The availability of N in legume biomass the subsequent plant cane crop as determined by 15N dilution technique, ranged between 21 and 44 kg N/ha. Incorporation of LGM prior to planting significantly increased yield of plant cane fertilized with half the recommended rate of mineral N. Based on the results of this study, current rate of fertilizer N for plant and 1st ratoon cane following a LGM crop may be reduced by half without any loss in yield.
