Compositional Nutrient Diagnosis (CND) Norms and Indices for Potato (Solanum tuberosum L.)

A survey was conducted in potato fields for collection of leaf samples to establish nutrient concentration yield data bank. The data bank was used for developing multivariate compositional nutrient diagnosis (CND) norms for assessing the nutritional status of selected centres of potato growing field...
