The Impact of Nano Processed Cattle Manure Combinations on the Yield and Quality Changes of Cotton

Sustainable agriculture necessitates the exploration of organic fertilizers to promote both crop productivity and soil health. The objective of this two-year study was to evaluate the effects of different combinations of processed cattle manure on the yield and quality of cotton crops, with a focus on determining the optimal dosage of these fertilizers. Parameters including seed cotton yield, lint yield, ginning percentage, and physiological traits such as chlorophyll content and normalized difference vegetation index (NDVI) were analyzed. Results revealed significant differences in yield and physiological traits among fertilizer treatments. Notably, combinations involving cattle manure as base fertilizer exhibited superior performance compared to synthetic fertilizer alone. The application of 230 kg da-1 of cattle manure as base fertilizer, in particular, resulted in optimal yield and quality, highlighting the potential of organic fertilizers in enhancing crop productivity. While synthetic fertilizers tended to enhance chlorophyll content, cattle manure applications promoted a more balanced improvement in yield components without compromising plant vigor. Integrating processed cattle manure into fertilizer regimes emerges as a promising strategy for sustainable cotton production. The dose of processed manure fertilizer will provide ten times less use than the dose of normal manure fertilizer. This will make the use of manure fertilizers more active and the use of organic fertilizers more widespread.
