Abstract: The present field was carried out during 2018-19 and 2019-20 at Student Instructional Farm, Department of Agronomy, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur with main objective to find out the technically feasible, qualitative, productive and economically viable effect of Sulphur and Zinc maize-wheat cropping rotation and to evaluate the response of these treatments on maize-wheat cropping system. The soil of university research farm is an Entisol with sandy loam texture, deficient in organic carbon available N and available Zn but medium in case of available P, K and available S. The pH and EC of soil are in normal range and responsive to macro and micro nutrients applied in balanced manner in view of the deficiency of these nutrients and vital metabolic role of the above nutrients in maize-wheat cropping system and studied in respective manners. 9 treatments comprises of viz., T₁ - Control, T₂- 50 % NPK, T₃- 100 % NPK, T₄- 50 % NPK + S, T₅- 100 % NPK + S, T₆- 50 % NPK + Zn, T₇ -100 % NPK + Zn, T₈ - 50 % NPK + S + Zn and T₉ - 100 % NPK + S + Zn. Results recorded significantly maximum grain, stover and biological yield, and harvest index in treatments comprising S and/or Zn with 50 or 100 % RDF both the year, however, it was highly significant over control. The highest grain and stover yield was registered with the application of T₉ (100% RDF+S+Zn) which remained at par with T₅ and significantly superior over rest of the treatments on both the years and pooled mean basis. The application of T₈ (50%RDF+S+Zn) recorded significantly higher yield over all the treatments of 50% RDF but found at par with T₄ (50%RDF+S) during course of investigation.
