Plant Micronutrient Balance and Crop Yield-Studies in Relation to Sugarcane Grown in the Calcareous Soil

Studies were conducted on sugarcane crop growrj in the calcareous soils of North Bihar soil application of B, Zn, Mn and Fe singly and in all possible combinations using FYM as the micronutrient carrier. It was found that six micronutrient treatments viz. B, Mn and Fe applied singly and in combinations viz., Fe+Zn, Fe+Mn and Mn+B improved the yield significantly. The variations in the crop yield and the plant's natural state of micronutrient balance were negatively correlated. The micro-nutrients such as Mn and Fe were involved in decreasing order of importance and their performance of their combination improved in presence of Zinc.
