Field trials were conducted at Agricultural Research Station, Perumallapalle, during 2012-13 and 2013-14 to evaluate the response of promising early maturing sugarcane varieties to different levels of nitrogen. Six early maturing varieties, viz., 2003V46, 2006T3, 2006T36, 2006T19, 2006T23 and 2006T8 were tested at five nitrogen levels, i.e. 0, 75, 100, 125 and 150 per cent of recommended dose of nitrogen (RDN: 224 kg ha-1). Application of nitrogen at 125 per cent RDN produced significantly greater number of millable canes, stalk yield and sucrose per cent. However, the effect of nitrogen levels on juice sucrose per cent was not significant. Hence, application of nitrogen at 280 kg ha-1 (125% RDN) is the most economical and viable nitrogen level for the plant cane in sandy loam soils of Southern agro climatic zone of Andhra Pradesh. Among the six early varieties, 2006T36 followed by 2006T19 responded well to the applied nitrogen and recorded higher cane yield.
