Sufficiency ranges (sr) and deviation from optimum percentage (dop) references for leaf blade and petiole analysis in ‘Red Grenache’ grapevines

Aim: To obtain specific references for the nutritional diagnosis of ten essential nutrients for leaf blade and petiole of ‘red Grenache’ (Vitis vinifera L.).Methods and results: Leaf blades and petioles from 36 vineyards of ‘red Grenache’ (Vitis vinifera L.) grafted on Richter 110 were collected and analyzed at flowering and veraison between 1992 and 2008. Using the compiled data bank, nutritional references for ten elements (N, P, K, Ca, Mg, Fe, Mn, Zn, Cu and B were calculated. Optimal values were those around the central data (µ ± 0.25σ), while excessive and deficient values were those beyond the tails of the distribution (µ ± 0.84σ). Percentile calculation was performed when transformations to normal distributions became unlikely.Conclusion: References for Sufficiency Ranges (SR) and Deviation from Optimum Percentage (DOP) methods were obtained for those ten nutrients studied.Significance and impact of the study: The proposed ‘red Grenache’ references for leaf blade and petiole contribute to the improvement of the accuracy of ‘red Grenache’ grapevine nutrient diagnosis based on tissue analysis. These references are a guide to assess the nutritional status of ‘red Grenache’ grapevine around the world in general and, with higher accuracy, for the Rioja region and areas with similar vineyard conditions.

“…With respect to Australian references, 'Tempranillo's DOP norms for leaf blade at flowering showed lower values for all nutrients, with the exception of Ca (Robinson, 2005). 'Barbera' and 'Nebbiolo' varieties present references with lower concentrations for N, P and B, and higher values for Ca, Fe, Mn, and Zn (Ciesielska et al, 2002). Furthermore, 'Tempranillo' DOP norms showed higher P, Ca, and Mg concentrations, and lower N and K, with respect to Bordeaux values (Loue, 1990).…”

“…However, if databases are treated correctly with appropriate statistical methods, provisional yet reliable references can be established with great economy of time and money, as opposed to references established entirely by field trials (Failla et al, 1993). This methodology has been successfully used to obtain references with nutritional diagnosis purposes, and even to compare between different varieties or vine growing regions (Failla et al, 1993(Failla et al, , 1995Ciesielska et al, 2002;Garcia-Escudero et al, 2013).…”

Deviation from optimum percentage (DOP) is a diagnosis methodology for leaf analyses which expresses the deviation for each element with respect to its optimal concentration. This deviation is an individual index for each nutrient and allows the sorting of all the analyzed nutrients according to their limitations. A nutritional survey was undertaken over eleven years in La Rioja (Spain), to establish reference concentrations for the nutritional diagnosis of Vitis vinifera L., cv. ‘Tempranillo’ grafted on Richter-110. Reference concentrations for DOP methodology are proposed, and sensibility for the nutritional diagnosis was evaluated for blade and petiole analysis of N, P, K, Ca, Mg, Fe, Mn, Zn, Cu, and B at flowering and veraison phenological stages by comparison between DOP and sufficiency ranges (SR) methods. Results suggest that petiole has lower sensibility than blade to detect deficiencies or excesses of N, P, K, Ca, Mg, Zn, and Mn at veraison. In addition, petiole is a better tissue than blade to detect Fe and B deficiencies or excesses. Therefore, our results make possible the right choice between tissues, leaf blade or petiole, for a general nutritional diagnosis of ‘Tempranillo’ grapevines. On the other hand, it is possible to evaluate the status of each nutrient in each phonological stage analyzing both tissues and comparing the nutrient status to its references, DOP or SR, in the most adequate tissue.

“…If the accuracy of each factor is reduced, will be affected on the norm of each element. Also, the amount of the element in the soil or plant is not quantitatively and expressed with terms such as positive and negative (Ciesielska et al 2002;Garcia-Escudero et al 2013). In the DRID system, unlike other methods, the interpretation of leaf analysis results does not depend on the physiological age and site of sampling and in this method, the leaf is considered to be the most important place for plant analysis (Beu ls 1973; Beverly et al 1984;Sumner 1977).…”

Quantitative Recommendation of Phosphorus Fertilizer Based On The Correlation Between Phosphorus of Plant Organs and Soil Phosphorus In Washington Navel Oranges

AimMany methods have been proposed to recommend plant nutrients, all of which are qualitative and based on the concentration of the element in the soil or leaves. But, in the "Integrated Plant and Soil System" (IPSS) method, there is a recommendation of fertilizer quantified and based on the correlation between concentration of elements in plant and soil organs. MethodsIn this study, 39 Washington Navel Oranges orchards were selected and in each orchard, three trees were chosen and sampled from roots, stems, leaves, fruit as well as the soil around the roots. Sampling was performed in late March and early May for two consecutive years and phosphorus was measured in the samples. After a correlation analysis between "soil properties and phosphorus of plant organs" with soil phosphorus, those factors that had a significant correlation with soil phosphorus were selected. And based on that, there was determined a regression model between them.ResultsAmong all the studied factors, fruit phosphorus had the highest correlation with soil phosphorus. Based on that, two regression equations were obtained by which the required phosphorus can be calculated.DiscussionsSince the physicochemical properties of each element are different from the other, so the leaf alone cannot be a good indicator to determine the nutritional status of all elements. Therefore, it is more logical that the fertilizer recommendation of each element is based on the correlation between the element in that organ of the plant that has the highest correlation with that element in the soil.
