Banana Manuring & Fertilization

By National Horticulture Board on 30 Apr 2016


The fertilizer dose depends upon the fertility of soil and amount of organic manure applied to the crop. For a good yield, 40-50 t/ha of well-decomposed FYM is incorporated into the soil. The recommended fertilizer dose for optimum yield is as follows -

Nutritional Deficiency :


Leaves of all ages become pale green. Mid ribs, petioles and leaf sheaths turn reddish pink and rosette in appearance. Plantations with poor root growth exhibit such symptoms. Bunch weight and fruit quality is affected.

Control : Application of urea (300g/plant) followed by irrigation is recommended.


Plants show stunted growth with poor root development. Old leaves show saw tooth marginalchlorosis, curling of leaves, breaking of petioles and bluish green color of younger leaves.

Control : Application of DAP (50g/plant) followed by irrigation is recommended.


The deficiency symptoms include orange yellow color of old leaves, scorching along the margins,reduction in total leaf area, curving of midribs etc. Choking of leaves delay flower initiation leading to reduction in yield and quality.

Control : Spraying Potassium Sulphate (1%) solution on the leaves is recommended.


The deficiency symptoms include deformation or absence of leaf lamina (spike leaf), marginal leaf necrosis and thickening of veins.

Control : Application of lime (50g/plant) followed by irrigation is recommended.


Yellow discoloration is observed in the mid blade and midrib portion however the margins of the leaf remain green. Purple mottling of the petioles, marginal necrosis and separation of leaf sheaths from the pseudo stem is also seen.

Control : Application of Magnesium Sulphate (25g/plant) followed by irrigation is recommended.


The deficiency symptoms include yellow or white appearance of young leaves, necrotic patches on the leaf margins, thickening of veins, stunted growth and small or choked bunches.

Control:Application of complex fertilizer (20:20:0:15) @ 20 g/plant followed by irrigation is recommended.


Narrow green edge appears at the leaf margins of second or third youngest leaf, which further spreads along the main veins towards the midrib. However, the interveinal areas remain green giving comb tooth appearance.Control : Spraying Manganese Sulphate (0.5%) on the leaves is recommended.


Symptoms appear mostly in limed soils or soils with high pH. Young leaves become smaller in size and more lanceolate in shape. In the furling leaf high amount of anthocyan in pigmentation appear on its underside. The unfurled leaf has alternating chlorotic and green bands. Fruit is light green, twisted,short and thin.

Control : Spraying Zinc Sulphate (0.5%) on the leaves is recommended. Iron The younger leaves turn yellow or white.Control : Spraying Iron Sulphate (0.5%) along with Urea (1%) on the leaves is recommended.


Both young and old leaves show symptoms of chlorosis and curve towards the base, which gives anumbrella like appearance to the plant.

Control : Spraying Copper Sulphate (0.5%) on the leaves is recommended.


Deficiency symptoms include reduced leaf area, curling of leaves, lamina deformation, appearance of white stripes perpendicular to the veins on the lamina of young leaves, thickening of secondary veins and inhibition of root and flower formation.

Control : Application of Borax salt (25 g/plant) in the soil around the root zone of the plant is recommended.
