An experiment was carried out during Rabi 2015-16 in deep black soil to study the effect of slow releasing nitrogen fertilizers on growth and yield of sugarcane at Agricultural Research Station, Dhadesugur, University of Agricultural Sciences, Raichur, Karnataka. Results revealed that, application of 125 % nitrogen through neem coated area recorded significantly maximum plant height (304.1 cm) and higher millable cane yield (125.3 t/ha) and which was onpar with the application of 125 % nitrogen through sulphur coated urea (302.5 cm and 123.1 t/ha, respectively) and application of 125 % nitrogen through coal tar coated urea (300.2 cm and 121.4 t/ha, respectively). Further, these treatments also recorded significantly higher net returns and benefit cost ratio. Whereas, application of 100 % recommended dose of nitrogen through commercial urea recorded significantly least plant height (275.3 cm) and millable cane yield (102.5 t/ha). Results concluded that, application of 125% nitrogen through either neem coated area or sulphur coated urea or coal tar coated urea was best to increase the millable cane yield in sugarcane by increasing the nitrogen use efficiency and reducing the nitrogen losses.
