Study Notes
Nitrogen Deficiency in Plants
- Stunted growth in plants primarily results from insufficient nitrogen, which is essential for synthesizing amino acids and proteins crucial for growth.
- Initial visual symptoms of nitrogen deficiency include yellowing of older leaves (chlorosis), as nitrogen gets redirected to newer growth when deficiency occurs.
- Severe nitrogen deficiency can hinder plant flowering, leading to reduced seed production and overall reproductive success.
- Maturity of some crops may be delayed due to nitrogen deficiency, affecting the time of harvest and yield potential.
- The primary effect of nitrogen deficiency is a decrease in protein content within plant tissues, as nitrogen is a key component of amino acids and proteins essential for plant health.
