Research on the Role of Micronutrient Management in Improving Cotton Fiber Quality

Cotton is an important fiber crop with significant global economic and industrial significance, and improving its fiber quality is essential to maintain competitiveness in the textile industry. This study explores the role of micronutrient management in improving cotton fiber characteristics such as length, strength, and fineness. We comprehensively study the physiological functions and agronomic importance of key micronutrients (i.e., boron, zinc, iron, and manganese) and analyze their effects on fiber development at the cellular and molecular levels. This review introduces effective soil and foliar application strategies, emphasizing an integrated nutrient management approach for optimal uptake and sustained productivity. A case study from India highlights the practical benefits and challenges of micronutrient interventions in cotton cultivation. We also discuss future directions, including nanotechnology applications, genetic advances to improve nutrient efficiency, and the integration of precision agriculture tools. This study highlights the need for micronutrient-centric agronomic practices, increased farmer awareness, and a supportive policy framework to achieve sustainable improvements in cotton fiber quality and overall crop performance.
