Nitrogen deficiency symptoms include stunted growth, lower protein content reduced deficiency incase of acute deficiency. Other symptoms include appearance of pale-yellow color leaves in the older leaves, starting from the tip due to reduced chlorophyll content. This is followed by death or dropping of older leaves depending on degree of deficiency. Low root/shoot ratio is observed due to increased root growth and stunted shoot growth. Nitrogen deficiency is common in nature. Plants have developed response mechanisms to nitrogen deficiency which include hormonal up regulation of root growth, and closing of aqua pores which results in shoot water stress and stunted shoot growth.
