PLANT ANALYSIS BASED ON THE DRIS SYSTEM: PROGRAMMING INTERFACE WITH A CASE STUDY IN PLANTAIN CROP (Musa AAB)

The Diagnosis and Recommendation Integrated System (DRIS) is a tool to evaluate the nutritional status obtain fertilizer recommendations of several crops. Unlike other methods, DRIS works directly with farmer’s information, focusing on understanding balance crop. However, selection indexes long time-consuming. objective this work was develop an algorithm estimate reference for crops in order facilitate use methodology. construction included four stages, (1) theoretical bases, (2) conceptual model design, (3) implementation, (4) validation. For database crop yield foliar analyses, developed divided into two subsets (high low yield), estimating nutrient ratios variability. leaf sample diagnosis, compares highy-ield population, generating numerically graphically. A imbalanced if its index graph outside whiskers. efficiency operability tested analyses fifty plantain distributed subregions Antioquia Department, Colombia. procedure allowed determining quantitative graphical information samples.
