Overview
Banana is one of the heaviest feeders among fruit crops and removes large amounts of nitrogen and potassium from the soil. Good bunch weight depends on steady, balanced nutrition right from planting through bunch emergence, not on a single big dose. ICAR-NRCB and State Agricultural Universities recommend a high N:K diet with moderate phosphorus, applied in many small splits or through drip fertigation. Potash is especially important because it decides finger filling, bunch grade and keeping quality. Banana also responds well to heavy farmyard manure and biofertilizers at planting. The figures below are a starting range per plant per year for the main crop. Always adjust them to your Soil Health Card or a fresh soil test, your variety such as Grand Naine or Nendran, and the advice of your local KVK, because soil and water differ from field to field.
Recommended NPK dose for Banana
A common range is about 150 to 250 g N, 40 to 100 g P2O5 and 200 to 400 g K2O per plant per year, depending on variety and region. For Grand Naine roughly 200:60:300 g NPK per plant is widely used, while tall varieties like Nendran may take up to 250:150:400 g. This works out to roughly 330 to 540 g urea, 250 to 640 g single super phosphate and 330 to 670 g muriate of potash per plant per year. Treat these as a starting range only and fine tune with your Soil Health Card, a fresh soil test and KVK advice.
Application schedule
Apply all phosphorus and farmyard manure at planting along with one third of the nitrogen and potash. Split the remaining nitrogen and potash into at least 4 to 6 doses given roughly at the 2nd, 3rd, 4th, 5th and 6th month after planting, finishing potash before bunch emergence. Under drip fertigation, give small weekly or fortnightly doses for best results. Stop heavy nitrogen once the bunch has emerged and shift the focus to potash for good finger filling. Apply fertilizer in a ring 20 to 30 cm away from the pseudostem and irrigate immediately after each dose.
Organic & bio-fertilizers
Apply 8 to 10 kg of well rotted farmyard manure or compost per plant at planting, and repeat yearly for ratoon crops. Vermicompost at 2 to 5 kg per plant can partly replace FYM. Treat suckers or soil with biofertilizers such as Azospirillum and phosphate solubilising bacteria at about 25 to 50 g each per plant to improve nutrient availability. Green manuring and crop residue or trash mulching in the inter row help build organic matter, conserve moisture and recycle potash back to the soil.
Micronutrients & deficiency signs
Zinc is the most common micronutrient deficiency in banana and shows as a yellow green striped or mottled look on younger leaves with narrow, bunched leaves. Iron deficiency turns young leaves pale yellow while the midrib stays green. Magnesium deficiency yellows the leaf margins of older leaves and can turn petioles bluish purple. Correct these with a foliar spray of 0.5 percent zinc sulphate, 0.5 percent ferrous sulphate or 0.5 percent magnesium sulphate, and add boron only if a soil or leaf test shows a need. Always confirm with leaf analysis or KVK advice before spraying micronutrients.
Tips & cautions
Drip fertigation is the best way to feed banana because it gives small, frequent doses and saves fertilizer. Always keep potash high through the crop and especially before and during bunch development. Apply fertilizer in moist soil and never against the pseudostem, which can burn roots. Do not put all nitrogen early as it causes lush growth and toppling. Remove the male bud after the last hand sets and keep the basin weed free. For ratoon crops, start feeding the selected follower sucker on the same split schedule.
These are general recommendations. For the exact dose, follow your Soil Health Card / soil test and local KVK, and avoid over-applying urea.
