Diagnosis and Recommendation Integrated System (DRIS) approach on Nutritional Diagnosis in Fruit crops- A Review

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.

Nutritional standards through Integrated Differential Diagnosis (IDD) in pomegranate (Punica granatum L.)

“…For TN, the deficiency occurs below 0.67%, the optimal mean is 1.35%, and the excess occurs when the content is greater than 2.66%. Savita et al (2016) reports a sufficiency range of 0.91-1.66%, which agree with the results obtained in this research, while Chater and Garner (2018) mention a percentage of 1.44% and 2.0% in pomegranates of the 'Wonderful' variety in California, while Urlic et al (2019) mention ranges of 1.41-1.67% in different varieties grown in Croatia. The P below 0.07% indicates deficiency in pomegranate and a sufficient-optimal range of 0.11-0.16% whose mean is 0.14%, while above 0.28% it is shown as an excess.…”

Sistema Integrado de Diagnóstico y Recomendación, su aplicación y utilidad en la agricultura. Una Revisión

“…In the last ten years, three scientific reviews have been published by Bangroo et al (2010), Kania & Callejas (2011), and Savita et al (2016 on the development of methodological proposals to obtain DRIS norms in various crops of agronomic interest and the calculation of their respective nutritional indices, but they do not elucidate the real functionalities that this diagnosis method in agriculture. This review aimed to present the applications and uses of the Diagnosis and Recommendation Integrated System developed during the last 10 years in agriculture worldwide through the systematic review of databases such as Redalyc, Scielo, ScienceDirect, Scopus, Springer Nature, Taylor & Francis, and Web of Science.…”

“…The nutritional diagnosis of crops is done with the results of chemical fertility analysis of soils, using the nutritional requirements of the studied species (Chacón-Pardo et al, 2013a;González, 2017;Herrera, 2015) and frequently the interpretation of nutrient concentrations in leaf tissue with widely used methods such as Critical Levels and Sufficiency Ranges (Bangroo et al, 2010;Savita et al, 2016). These methods are based on the individual comparison of the nutrient concentration in the sample with an accepted value of normality for a certain phenological stage without taking into account the relationships between nutrients and their possible imbalances (Kania & Callejas, 2011).…”

“…In 1975, Sumner introduced DRIS to the United States (González, 2017). Since then, diagnosis norms have been determined for several extensive, forage, fruit, and vegetable crops and for timber species (Bangroo et al, 2010;Kania & Callejas, 2011;Savita et al, 2016).…”

“…DRIS uses the results of leaf analysis or chemical fertility of the soil to identify the most limiting nutrient in the development of a crop. The evaluation is done by comparing the relative balance of the content of a nutrient against the DRIS nutritional diagnosis norms established for the species (Savita et al, 2016). According to Walworth and Sumner (1987), the theoretical bases of this system are founded on the fact that the relationship between nutrients is a better indicator of the nutritional status of the plant than the isolated values.…”
