Diagnosis and Recommendation Integrated System (DRIS) approach on Nutritional Diagnosis in Fruit crops- A Review
Journal Title: Journal of Applied and Natural Science - Year 2016, Vol 8, Issue 4
Abstract
Diagnosis and Recommendation Integrated System (DRIS) is widely used statistical approach for interpretation of the plant tissue analysis data and to diagnose the plant nutreint needs much earlier than the reduction of crop yield with greater accuracy. It helps in simultaneous identifying imbalances, deficiencies and excesses of crop nutrients and ranks them in the order of their importance for their remedial steps. The DRIS norms based on foliar composition can developed in any crop and at any stage of its development. It provides a mathematical means of ordering large number of nutrient ratios into nutrient indices that can be easily interpreted. The nutrient ranges been established as deficient, low, optimum, high and excessive based on the mean of nutrient concentration and standard deviation from high yielding population to serve as a guide for a quick and routine diagnostic and advisory purpose. The major advantage of DRIS lies in its ability to minimize the effect of variation in tissue age on diagnosis, which allows a choice of wider range of tissues than permissible under the conventional critical value approach. Thus, DRIS is holistic in nature for identification of nutrient imbalance in crops and formulation of nutrient management strategies for achieving higher yields.
