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 Inde...

Abstract Low nutrient use efficiency in maize as a result of imbalanced nutrition has been reported to drastically reduce yield. We implemented omission experiment assess the effect application on yield and nutritional balance. Maize ear leaves were analyzed for nutrients, identify balance status using Diagnostic Recommendation Integrated System (DRIS) approach. Results indicated that N or P re...

The aim of this study was to establish DRIS (Diagnosis and Recommendation Integrated System) norms Nutritional Optimal Ranges (NOR) for ‘Rojo Brillante’ Protected Designation Origin (PDO) ‘Ribera del Xúquer’. database contained 800 leaf samples collected in different crop phenological stages [after flowering (AF), fruit enlargement (FE), colouring (FC), harvesting HV)]. (78) were established ma...

Diagnosis and Recommendation Integrated System (DRIS) norms were derived for crisphead lettuce (Lactuca sativa L.) from field fertility experiments conducted over the past 20 years on mineral and organic soils in Florida. Preliminary testing indicates that DRIS diagnoses generally agree with diagnoses using the sufficiency range approach, with the advantage of predicting the degree of nutrient ...

Beaufils' experimental approach and calibration technique with a formula (DRIS for Diagnosis and Recommendation Integrated System) is applied to sugarcane cultivation. Provisional norms for soil pH, P, K, Ca, Mg and plant N, P, K, Ca and Mg are presented in the form of indices. They all are derived from a single general formula. The steps followed for establishing these norms, by interpreting d...

The aim of this study was to compile DRIS (Diagnosis and Recommendation Integrated System) norms sufficiency ranges for pepper grown in greenhouses the determination variation during different phenological stages crop. were constituted by 367 leaf samples Capsicum annuum L. which collected crop (flowering (FL), fruiting (FT), fruit development (FD), harvesting (HV)). Two developed; one includin...

Recently Beaufils published a monograph entitled Diagnosis and Recommendation Integrated System (DRIS) in which he presented complete details of his experimental approach and plantlenvironment calibration technique for the first time. One of the cardinal points of this diagnostic technique is that it should be applicable to a particular crop grown at any place at, any stage of its development. ...
