Cotton Specialist Exam 2025 – 400 Free Practice Questions to Pass the Exam

Applying nitrogen fertilizers is a well-established practice to address nitrogen deficiency in cotton plants. Cotton is a crop that requires a significant amount of nitrogen for optimal growth and development, as nitrogen is a critical component of amino acids, proteins, and chlorophyll. When cotton plants are deficient in nitrogen, they can exhibit poor growth, yellowing of leaves, and reduced yield.

By applying nitrogen fertilizers, farmers can directly supply this essential nutrient to the soil, thereby promoting better plant health, enhancing photosynthesis, and ultimately increasing the cotton yield. This practice is especially important in soils that are low in nitrogen or when the previous crop has depleted soil nitrogen levels.

The other practices listed do not effectively counteract nitrogen deficiency. Increasing herbicide use does not provide any nutrients and could potentially harm the plants' health. Reducing watering frequency might stress the plants, worsening growth conditions rather than alleviating nutrient deficiencies. Rotating with non-leguminous crops, while useful for soil health and pest management in some contexts, does not replenish nitrogen levels in the same way that applying nitrogen fertilizers does.
