Question

Stunted growth and small yellow leave in plants are symptoms of the deficiency of what? 

Answer 1

Stunted growth and yellow leaves in plants are symptoms of the deficiency of nutrients. The most common nutrient deficiencies in plants are nitrogen, phosphorus, and potassium. It is important to identify the nutrient deficiency and provide the necessary fertilizer or soil amendments to correct the issue.

Answer 2

Stunted growth and small yellow leaves in plants are symptoms of nutrient deficiency, particularly nitrogen, phosphorus, or iron. A lack of nitrogen can result in stunted growth and yellowing of older leaves, while a lack of phosphorus can result in small, dark green leaves. Iron deficiency can cause yellowing of younger leaves.
