The concentration of different nutrients as influenced by levels and rates of N and K fertigation was monitored in Robusta banana grown on Aquic Haplustalfs soil. Nitrogen and potassium were applied @ 50, 100, 150 or 200 g/plant/crop in 1:1, 1:1.5 or 1:2 ratio. The concentration of N in leaf was highest at late-vegetative stage. The N and K fertigation in different ratios before or after flowering did not show any significant increase in yield. The highest yield (73.26 tonnesha) was obtained with the application of 100 g N and K/plantkrop.
