Solution – You should apply 2 % DAP foliar nebuliser at the biweekly interval .
Potassium – greensickness along the sharpness of leaves is first among the old leafage . The growth of works lack in K will slow and stunt growth . The size of seeds and yield and their production lessen .
Solution – You should use 2 % K2SO4 foliar spray at biweekly intervals .
Calcium – symptom first come along on small leaves and foliage tips . New emerging leaves can stick together on the security deposit , causing leave to amplify and unfurl . Small leave can be crinkled , with terminal buds getting damaged .
