Article Info		Abstract
Received: 16-08-2015, Revised: 22-09-2015, Accepted: 29-09-2015		Sixty six selected gardens of mulberry (Morus sp.) growing under Chhotanagpur plateau of Jharkhand and Eastern Ghat of Odisha were surveyed under the present study. Diagnosis and Recommendation Integrated System (DRIS) based model was employed to ascertain optimum foliar concentration of cationic micronutrients for mulberry. DRIS indices for those micronutrients were computed on the basis of their foliar concentrations in mulberry growing under the said agro ecological zone (AEZ). Regression analysis was used to fit a model relating DRIS indices to foliar concentrations of the micronutrients. Foliar micronutrient concentrations of mulberry exhibited a positive and significant relationship with DRIS indices. Appropriate exercise on the data base computes the optimum foliar concentrations of cationic micronutrients for mulberry growing under the said AEZ as 12.53 mg kg-1 for Zn, 3.16 mg kg-1 for Cu, 175.06 mg kg-1 for Fe and 75.95 mg kg-1 for Mn, respectively. The approach is capable of diagnosing micronutrient deficiency in mulberry and in turn, can help in enhancing its productivity through the correction of nutritional imbalances.
