Field trail was conducted at Agricultural Research Station, Perumallapalle in two plant crops to evaluate the response of mid late maturing sugarcane varieties to different doses of nitrogen fertilizer. Four midlate varieties viz., 2012T58, 2012T72, 2012T78 and 2012T182 were tested at four nitrogen levels i.e., 100%,125%,150% and 175% of recommended dose of nitrogen (RDN: 224 kg/ha). Application of nitrogen @ 150% RDN produced significantly higher values for millables canes, cane yield and per cent sucrose. Hence application of nitrogen @ 336 kg /ha is the viable fertilizer nitrogen for midlate varieties of sugarcane crop in sandy loam soils of southern agro-climatic zone of Andhra Pradesh. However, the effect of nitrogen levels on juice quality parameters was not significant. Among the sugarcane midlate varieties, 2012T58 and 2012T 182 responded well to the applied nitrogen and recorded higher cane yield.
