A field experiment was conducted during rabi seasons of 1996–97 to 1998–99 at Deesa to evaluate drip fertigation for water and fertilizer economy in relation to potato tuber yield. Application of 80% of recommended dose of N and K2O through drip fertigation was found to be the most efficient in obtaining significantly higher total tuber yield (420 q/ha) as compared to application of recommended dose of N and K2O through furrow irrigation. Fertigation also resulted in better fertilizer use efficiency by savings 40% water and labour.
