... The identification of nutritional disorders in plants induced by cadmium (Cd), based only on nutrient concentration, can fail and conceal links with biochemical and physiological events. In this study, the diagnosis and recommendation integrated system (DRIS) and nutritional balance index (NBI) were evaluated as auxiliary tools for diagnosing nutritional disorders in two Panicum maximum genotypes ...

... The rates of nitrogen, phosphorus, and potassium fertilizers used in the cultivation of potatoes are often considered excessive, as they can cause imbalance among the essential elements present in the soil. Using leaf nutrient analysis, this study aimed to evaluate the productivity of potato tubers subjected to different rates of nitrogen (N), phosphorus (P), and potassium (K) to establish the dia ...

Diagnosis and Recommendation Integrated System (DRIS) norms for nitrogen (N), phosphorus (P), potassium (K), sulfur (S), chlorine (Cl) and sodium (Na) and nutrient sufficiency ranges for Aloe vera, Kalanchoe blossfeldiana, Lavandula multifidi, and Rosmarinus officinalis were based on two experiments. DRIS norms and nutrient ratios were computed and selected. Nutrient sufficiency ranges were develo ...
... The aim of this work was to establish for the first time nutrient optimal range (NOR) for mandarins in Tunisia using two methods: Diagnosis and Recommendation Integrated System (DRIS) and Compositional Nutrient Diagnosis (CND). The study was performed using data from 120 mandarin’s commercial orchards, in several locations in Tunisia. Yield data and leaf nutrient content from 2011 to 2014 cropping ...
... Sustainable production in the Everglades Agricultural Area (EAA) is confounded by decreasing soil depth and high annual rainfall. Formerly a sawgrass marsh, Histosols predominate much of the EAA and these soils have frequently flooded following their drainage in the early 20th century. Subsidence has increased inundation frequency as soil depth has decreased to less than 25 cm in many locations. A ...

... 'Keitt' mango fruits with internal breakdown and healthy flesh from three different producing areas were used in a study that aims to determine the concentrations of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), copper (Cu), manganese (Mn), zinc (Zn) and boron (B) to analyse the relationship between the internal breakdown and mineral nutrition in the flesh. A significa ...
... In this work, we investigated phosphorus (P) availability of three soil orders (Entisols, Inceptisols, and Mollisols) in the Kurdistan Region of Iraq. Addition of P fertilizers causes chemical and physical fixation of P due to the high amounts of calcium carbonate often present in the soils of this region. Understanding these fixation processes is important for predicting and managing P availabili ...

Abstract:
... Brazil is a significant global grape producer (Vitis spp.). The state of Rio Grande do Sul produces 59% of the national output. Despite the large national production, the grapevine has not yet been tested sufficiently to obtain data from long-term experiments in both production as well as suitable nutritional management. The DRIS method is one of the useful tools required to assess plant quality. ...
... The Diagnosis and Recommendation Integrated System (DRIS) was used as a tool to assess the limiting nutrients for wheat growth. To this effect, two separate greenhouse experiments were conducted to assess the limiting nutrients for wheat growth using soil samples collected from Wolmera district, Ethiopia. The experiments consisted of eight fertilizer treatments, optimum (Opt.), optimum-N (Opt-N), ...
... The improvement in forest productivity by considering the balance of nutrient input-output is the proper choice. This research aimed at investigating the macro nutrient status of a teak plantation in Indonesia. The quantitative measurement of the nutritional status of a plantation was done by picking sample plantations and doing laboratory analysis. The determination of macronutrition status was c ...

Abstract:
... Foliar analysis has been an important method for diagnosing the nutritional status of plants. Therefore, this work aimed to determine benchmarks (norms) for interpretation of results of foliar analysis by the methods of Diagnosis and Recommendation Integrated System (DRIS) and Nutritional Composition (CND) and to determine the order of nutritional limitation and the potential response to fertiliza ...
... The leaf nutritional status of mango orchards was assessed using diagnosis and recommendation integrated system (DRIS). The DRIS norms, which showed higher variance and lower coefficients of variation, are found to have greater diagnostic precision. As per DRIS indices, a relative deficiency for magnesium, zinc, and boron corresponding to relative sufficiency for calcium, nitrogen, phosphorus, sul ...
... The consequences of forest fragmentation and edge effects on soil nutrient availability and nutrition of sugar maple (Acer saccharum Marsh.) forests remain understudied. We assessed soil chemistry (bulk pH, total carbon (C) and nitrogen (N), extractable phosphorus (P), exchangeable cations, and mineralizable N) and foliar nutrition (N, P, potassium (K), calcium (Ca), and magnesium (Mg)) of mature ...

... The efficiency of methods in adequately interpreting the nutritional status of Eucalyptus spp. rooted cuttings remains unknown. The aim was to evaluate the quality of diagnoses obtained using the critical level (CL), diagnosis and recommendation integrated system (DRIS) and compositional nutrient diagnosis (CND) methods to assess the nutritional status of Eucalyptus spp. rooted cuttings, based on ...
... The diagnosis and recommendation integrated system (DRIS) approach was used to interpret nutrient analyses of leaf tissues from pomegranate cv. Bhagwa orchards grown in southwestern Maharashtra, India. The DRIS norms were established for three growth stages, viz. 50% flowering, fruit development and first harvesting of pomegranate. Various nutrient ratios were obtained from high-yielding populatio ...
... The objective of this study was to establish a nutrient sufficiency range and DRIS standards of Conilon coffee grown in southern Bahia, Brazil for the pre-flowering and grain-filling stages and to perform a nutritional diagnosis of these plants using different methods. The collections were performed in 24 Conilon coffee farm fields to establish the leaf nutritional standards, and 278 samples were ...
... Bacterial blight disease caused by Xanthomonas axonopodis pv. punicae is a major threat to pomegranate cultivation causing heavy losses. An attempt was made to establish nutrient sufficiency range for imparting moderate disease resistance and diagnosing nutrient imbalance causing disease development. Two approaches i.e. Diagnosis and Recommendation Integrated System (DRIS) and Compositional Nutrie ...

Abstract:
... High yield of sugar beet require adequate mineral nutrition. To be diagnosed across interacting nutrients using appropriate interpretation models, the plant must be sampled at a critical physiological stage. This study aimed to develop and validate norms at the 7-leaf and well-developed rosette stages, for diagnostic purposes using the Diagnosis and Recommended Integrated System (DRIS) and Composi ...

Abstract:
... Chemical analysis of leaves is an effective tool for detecting nutritional imbalances and providing data for fertilizer recommendations. Therefore, it is extremely important to establish criteria for interpreting these results. The DRIS (Diagnosis and Recommendation Integrated System) method is an alternative to the interpretation of results of leaf analysis as it allows the calculation of indexes ...
