Nendran is the popular variety grown commercially in different regions due to its wider adaptability and high degree of tolerance to drought in a perennial cropping system. A field experiment was performed in randomized block design with ten treatments of various ratios of nitrogen and potassium to study their nutrient concentrations in banana leaves and soil at vegetative and harvesting stage. The results revealed that the treatment 9 with the ratio of N₂₅₀P₈₀K₄₀₀ showed the highest mineral content in leaves at both the vegetative and harvesting stage. Therefore the fertilizers with the dosage of N₂₅₀P₈₀K₄₀₀ are optimum for growing the plants.
