Production potential and quality parameters of cotton (Gossypium hirsutum L.) as influenced by integrated nutrient management option in cotton-sunflower cropping system

摘要

Field experiments were conducted during kharif and rabi seasons 2002-03 and 2003-04, respectively to investigate the response of cotton to integrated nutrient management in cotton - sunflower cropping system. Highest seed cotton yield (23.47 and 26.93 q ha(-1)) and stalk yield (57.84 and 64.32 q ha(-1)) were obtained with combined application of all the three sources of N [50% RDF + FYM + Mungbean Intercrop Incorporation] that remained at par with individual application of 100% RDF as well as combined application of 50% RDF and FYM. Quality parameters viz., ginning percentage, lint index, seed index, Bartletts index, fibre length, fibre fineness, bundle strength and maturity coefficient were remained unaffected due to various N management practices in cotton, however, higher values were observed with either application o FYM alone or in combination with other N sources.
