A field experiment was conducted at Gangavathi, Karnataka, during the rainy (kharif) season of 2017 and 2018, to know the response of genotypes to nutrient management under drip irrigation in dry direct-seeded rice. The pooled mean of 2 years indicated that, drip fertigation with water-soluble nitrogen fertilizer (WSNF) in 8 splits at 10 days interval recorded 23% higher grain (5,197 kg/ha) and 20% higher straw yield (5,637 kg/ha) than soil application with 100% NPK fertilizer. ‘GNV 10-89’ variety recorded higher grain (5,244 kg/ha) and straw yield (5,696 kg/ ha) than ‘BPT 52-04’. Drip fertigation of WSNF applied in 8 splits at 10 days interval, recorded significantly higher nitrogen uptake (170.1 kg/ha) and nitrogen-use efficiency (34.6 kg/ha) than soil application with 100% NPK fertilizer.
