An experiment was conducted to determine the influence of intra-furrow spacing and nitrogen fertilization on the formation of millable stalks of two sugarcane varieties and also to determine the nitrogen uptake of the 2 varieties and their relation to their sugar yields. Planting sugarcane at a distance of 50 cm between hills in a furrow gave the highest number of tillers on both Phil 56226 and Phil 6607 and that maximum tiller formation occurred at 6 months. On the average millable stalks of Phil 56226 increased with increasing levels of nitrogen while Phil 6607 did not respond to added inputs of nitrogen. N uptake of Phil 6607 was significantly higher than that of Phil 56226 at all levels of nitrogen. Data showed that 180 kg N/ha is the optimum level which gives the highest N uptake since added inputs above this level tends to lower the uptake of both varieties. Furthermore data revealed that nitrogen at harvest tends to increase tonnage but decreased PS/TC which eventually gave low sugar yield
