🔍 लक्षणहरू

Blossom End Rot (BER) in tomato and pepper — dark sunken leathery brown/black area at blossom end of fruit. Tip burn on inner leaves of cabbage and lettuce. Distorted crinkled young leaves with brown margins. Hollow or bitter pit in apple.

⚡ कारण

Irregular watering causing calcium uptake fluctuations; excessive potassium or ammonium nitrogen fertilizer competing with calcium uptake; high evaporation rates; insufficient calcium in acidic sandy soils.

🛡️ रोकथाम

Maintain consistent soil moisture with mulching and drip irrigation; apply lime to acidic soils (pH < 5.5); avoid excessive potassium or ammonium nitrogen; side-dress with calcium nitrate.

🌿 जैविक उपचार
Foliar spray of crushed eggshell extract or bone meal tea; apply wood ash around plant base; mulch to maintain even moisture; apply oyster shell or dolomite lime to acidic soils.
⚗️ रासायनिक उपचार
Foliar spray of Calcium Nitrate Ca(NO3)2 solution at 2-4g per liter every 10-14 days; for acidic soils apply Agricultural Lime (CaCO3) at 2-4 t/ha based on soil test.
