A field experiment was conducted during kharif 2015 to asses the spatial variability and precision nutrient management through drip irrigation in aerobic rice at ZARS, GKVK, Bangalore. The experimental field has been delineated into 48 grids of 4.5 m x 4.5 m using geospatial technology. Soil samples from 0-15 cm depth were collected and analysed. There was spatial variability for available nitrogen (154 to 277 kg ha^-1), phosphorous (45 to 152 kg ha^-1) and potassium (200 to 346 kg ha^-1). The variability was addressed through precision nutrient management approach with target yield. Application of 25 % N & K from sowing to 30 DAS + 25 % from 31 to 50 DAS + 25 % from 51 to 80 DAS + 25 % from 81 to 105 DAS through drip irrigation recorded significantly higher grain yield (11.0 Mg ha^-1) over application of N & K as per package of practice (9.2 Mg ha^-1) which was 20.2 per cent higher over application of N & K as per UAS (B) recommendations through drip irrigation and 70.1 per cent over soil application. Targeted yield of 12 Mg ha^-1 recorded significantly higher grain yield (12.8 Mg ha^-1) over rest of the targets. The actual yields were 22.0, 11.3, 8.2 and 7.3 per cent higher than the targeted yields of 6, 8, 10 and 12 Mg ha^-1, respectively.
