Solution(By Examveda Team)

Premature leaf fall is caused due to the deficiency of nitrogen.
Premature leaf drop is prevalent in the landscape due to dry weather. Plants are drought damaged by leaf desiccation, slowing of photosynthesis, and slowing of growth. Leaves wilt or roll, turn off colour and drop.
Symptoms of nitrogen deficiencies in plants are general chlorosis of the leaves, which is when leaves turn pale green and leaves cup upwards quite severely in deficient plants.
