Nowadays there have many calls to preserve the environment in all areas of humanity''s life. For this reason I have written this book on cotton as the most important strategic crop in Egypt and plays a major role in the Egyptian national economy because* It is an important source of raw material in the cotton textile industry.* As well as being a source for a lot of other unusual economic products .* I consider cotton as a magic plant. So we should not think only of the cotton linter (As white gold).* Cotton has magic economic parts . So I called it “White and yellow gold plant”.* All these magic parts provide an additional outcome for the farmers.
