Fertilizers & Manures
Type Quantity / Notes Additional Info
FYM 20-25 tonnes of FYM per hectare before the last ploughing
Nitrogen (N) 200 kg/ Ha 1/3rd of N as basal dose at transplanting. Apply the remaining N in two equal split doses at 30 and 60 days after transplanting
Phosphorus (P₂O₅) 250 kg/ha entire amount as basal dose at transplanting
Potassium (K₂O) 250 kg/ha entire amount as basal dose at transplanting
Any special cases: No
Sandy soil fertilizer supply:Apply N in three split doses.
The 1st dose of N should be applied along with phosphorus and potash. The 2nd dose of N should be applied just before the plants take up active growth and the 3rd dose of N when the first flower clusters have started setting fruits.Under high fertility conditions, the application of N should be reduced, as the blossoms may fail to set fruit due to the unfavourable carbohydrate nitrogen ratio within the plant.
Irrigation Drip irrigation recommended once every 3 days
Weed Control Regular manual weeding to keep the field weed-free
Any Special Crop Practices Support plants using stakes or trellises. Start staking ~30 days after transplanting

Disorder / Symptom Description & Control
Blossom-End Rot (BER) A dark, leathery, sunken area at the blossom end (opposite the stem) of the fruit. It usually starts as a small, water-soaked spot. * Maintain consistent soil moisture: Water regularly and deeply, especially during fruit development. Mulching can help conserve moisture. * Soil testing: If the soil is deficient, incorporate calcium-rich amendments like gypsum or lime before planting. * Avoid excessive nitrogen fertilization: This can promote vegetative growth at the expense of fruit development and calcium uptake
Control: Application of CN @ 15-20 Kg/Ha or spraying of Anhydrous Ca EDTA @0.5-1 gm /ltr
Fruit Cracking / Splitting Splits or cracks on the fruit surface, usually radial (extending from the stem end) or concentric (circular around the stem end). Maintain consistent soil moisture: Regular and even watering is crucial. Mulching: Helps regulate soil moisture and temperature. Avoid excessive nitrogen fertilization: Use a balanced fertilizer. * Harvest fruits at the mature green or breaker stage: Ripe fruits are more susceptible to cracking Irrigation management
Blotchy Ripening (Cloudy Spot / Gray Wall) Uneven ripening with blotches of green, yellow, or red on the fruit surface. Internal discoloration and hard, grayish areas may also be present. Ensure adequate light exposure. Maintain balanced fertilization.
Control: Use resistant varieties, control vectors (aphids), and practice good sanitation. Avoid root damage during cultivation
Yellow Shoulder (Green Shoulder) The shoulder area (near the stem) of the ripening fruit remains yellow or greenish-yellow and hard, even when the rest of the fruit turns red. Choose less susceptible varieties. Provide some shade during the hottest part of the day. Ensure adequate potassium nutrition.
Cat’s Face Mishappen fruits with enlarged scars and holes in the blossom end of the fruit caused by cool and abnormal temperature , disturbance to flowers , herbicide exposure
Control: Avoid cool seasons and maintain adequate soil moisture.
Sun Scald Whitish shiny blisters on the fruit which results in a sunken area that may become pale yellowish and wrinkled causes heavy pruning escepcially when the foliage cover is low or loss of foliage due to disease and coupled with high temperature
Control: Carefull pruning and harvesting, good foliage disease control
