The lower leaves turn yellow and in some crops they quickly start drying up as if suffering from shortage of water, stunted growth, leaves & fruits shedding & whole plant becomes yellow, are deficiency symptoms of:_________?

Question

Accepted Answer

Both a & c. The symptoms described (yellowing lower leaves, drying up like water shortage, stunted growth, shedding of leaves/fruits, and whole plant yellowing) are classic signs of both Potash (Potassium) deficiency (causes yellowing/drying of older leaves and fruit shedding) and Calcium deficiency (causes stunted growth and leaf/fruit drop). Therefore, 'Both a & c' is the most accurate answer.
