Cracking of Lemon & Pomegranate: Reasons and Remedies
Sometimes, fruits develop cracks before harvest or during maturity. This is considered to be a physiological disorder in the trees. Fungus and bacteria may enter the fruits and decay occurs, such as lemon cracking, star-shaped cracking of pomegranate fruits, and sometimes deep cracking of the pulp is also observed in both fruits. Reasons for cracking of fruits: • Sudden changes in the environment • Deficiency of boron, calcium or nitrogen • Unseasonal rainfall during hot weather • Virus and fungal attack • Decrease in the amount of gibberellic acid • Direct sunlight on fruits • Sudden increase in environmental temperature
Remedies: • Adopt an effective irrigation system. • Stagnant water should not persist for a longer period after irrigation or monsoon rain. • To prevent nutrient deficiency, spray Borax 0.02%, Copper Sulphate 0.3 %, and Potassium Sulfate 2% in lemon. In addition, spray NA @ 20 ppm and Gibberellic Acid @ 10 ppm. Spray Borax @ 1% in June in pomegranate and also spray Gibberellic Acid @ 120 ppm. • Follow scientific cultivation practices. Dr. T. M.
