EFFICIENT USE OF WATER AND FERTILIZERS THROUGH DRIP FERTIGATION IN POTATO

摘要

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 K_2O 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 KJO through furrow irrigation. Fertigation also resulted in better fertilizer use efficiencyby savings 40% water and labour.
