%X A field study was conducted for three consecutive years from 2012-13 to 2014-15 at Regional Agricultural Research Station, Anakapalle to study the effect of water and nutrient management practices with drip irrigation and fertigation on yield and quality of sugarcane. The study was conducted with three methods of irrigations viz., surface drip, sub surface drip and furrow irrigation and four nitrogen levels (100, 150, 200 and 250 Kg N/ha) in split plot design. The test variety 97A85 (Visakha) was planted in paired rows (60/120 cm) and the surface and subsurface drip laterals were installed in the rows of each pair. In sub surface irrigation system laterals are placed at the depth of 15 cm in the soil. Significant differences in cane yield were observed due to different methods of irrigation and application of different levels of nitrogen. Pooled mean data of three years indicated that sub surface (104.5 t/ha) and surface (100.5 t/ha) irrigation methods gave significantly highest cane yield as compared to furrow method of irrigation (86.6 t/ha). Among different nitrogen levels, application of 200 Kg N/ha recorded significantly higher cane yield of 101.2 t/ha. Further increase in nitrogen dose does not increased the cane yield significantly. Highest percent juice sucrose was recorded in drip irrigation treatments as compared to furrow irrigation. Among different nitrogen levels, application of 150 Kg N/ha recorded higher juice sucrose percent (17.2). There is saving of water to the extent of 35.2% in drip irrigation as compared to furrow irrigation. Among different methods of irrigation, sub surface (1210 Kg/ha-cm) and surface (1170 Kg/ha-cm) methods of irrigations registered higher water use efficiency as compared to furrow method of irrigation (680 Kg/ha-cm)
