| Abstract | Sugarcane (Saccharum officinarum L.) is widely cultivated in tropical and warm-temperate regions (Reis et al. 2007). Recently, the use of sugarcane alcohol (ethanol) as an automotive fuel to replace gasoline has rapidly increased (Boddy et al. 1995, Marris 2006). Sugarcane is a C4 plant, which has an efficient photosynthetic system. It grows up to 4 m in height and the thick stem stores a high concentration of sucrose, which is present in the expressed juice at between 12 and 20% (W/V). In some areas of Brazil, sugarcane has been grown continuously for more than 100 years without any N fertilizer being applied at all (Dong et al. 1994). This circumstantial evidence suggests a high potential for biological nitrogen fixation (BNF) in sugarcane. Using a N dilution technique, Urquiaga et al. (1992) calculated the contribution of BNF in several cultivars of sugarcane, and found it to be about 70% for the most promising genotypes. Yoneyama et al. (1997) reported the contribution of BNF using a N naturalabundance method in Brazil, the Philippines and Japan, comparing the abundance of δ N in sugarcane with that in neighboring weeds as control plants. At many but not all of the sites in Brazil, a contribution from BNF was detected. Asis et al. (2002) estimated the contribution of nitrogen fixation of Japanese sugarcane cultivar NiF-8 by N dilution and natural N abundance techniques, and total %Ndfa (percentage of N derived from atmospheric dinitrogen) were estimated 27-38%. Hiyama et al. (2013) investigated the contribution of nitrogen fixation by N dilution in NiF-8 with different N application period. Although %Ndfa were slightly lower in N sufficient plants (15%) compared with N limited plants (20%), the absolute amount of Ndfa was higher in N sufficient plants (87 mgN plant) than N limited plants (57 mgN plant) at 20 weeks after transplanting. Nishiguchi et al. (2005) also estimated the contribution of BNF using N dilution technique, and found that between 10% and 40% of sugarcane N was derived from biological nitrogen fixation |
