Reference values for nutritional diagnosis of ‘Gigante’ cactus pear by DRIS and BIK methods

ABSTRACT The equilibrium and nutritional balance of plants are known to be utmost importance evaluate their yield potential comprehend the dynamics nutrients in soil-plant system. Hence, present study determined reference values for evaluating status ‘Gigante’ cactus pear cultivated with organic fertilization semiarid conditions by Diagnosis Recommendation Integrated System (DRIS) Balanced Indexes Kenworthy (BIK) methods. cladodes contents dry matter 72 plots were employed. database was classified into a high-yield low-yield population, above below 19.93 Mg ha-1 cycle-1, respectively. five ranges nutrient defined based on standard deviation range(s) DRIS indexes population. Furthermore, fixed BIK made it possible ascertain lower upper limit cladodes. all methods varied from each other those reported literature. These efficient identifying limiting pear, differences hierarchical order limitation, due lack or excess, not productivity.
