“…The wide temporal variation in petiole K in the weeks before and after bloom was demonstrated long ago (Christensen, 1969). Petiole K concentrations were, however, better correlated to yield, must acid levels, and must K concentrations than were leaf blade K concentrations in a survey of Agiorgitiko (red wine grape cultivar) vineyards in Greece (Assimakopoulou and Tsougrianis, 2012). Unfortunately, only the correlation coefficients were given in that study, making comparisons to this and other trials difficult.…”

“…The guidelines to diagnose adequate nutrients in either leaf blades or petioles have been developed in large part by conducting surveys of numerous vineyards in a given region, with occasional plot trials where nutrient supply (fertilizer use) has actually been manipulated and altered the productivity of vines (Assimakopoulou and Tsougrianis, 2012;Christensen 1969Christensen , 1984Conradie, 2001; Conradie and Saayman, 1989;Cook, 1966;Davenport et al, 2012;Robinson, 1992;Robinson et al, 1978). The reliance on surveys to provide ranges of nutrient status that are used as production guidelines can be misleading.…”

Grape growers rely on tissue tests of leaf blades or petioles for routine monitoring of vine nutritional health and for diagnosing potential nutrient deficiency or toxicity. There has been a long-standing debate as to which tissue better reflects the nutrient status of vines. A comparison of leaf blade and petiole nutrient concentrations was carried out to investigate which tissue better relates to vine growth, yield, and must nutrient responses of ‘Pinot noir’ grapevines to varying levels of nitrogen (N), phosphorus (P), and potassium (K) supply using data from a pot-in-pot vineyard over 4 years. Leaf blades and petioles were collected at 50% bloom and 50% veraison in each year and N, P, and K concentrations were assessed as predictors of leaf area at veraison, pruning mass at dormancy, yield, and must nutrient concentrations at fruit maturity. Data from commercial ‘Pinot noir’ vineyards were also used to investigate the relationship between leaf blade and petiole N concentrations with must N levels. Results indicated that leaf blades were superior to petioles in predicting vine growth, yield, and must yeast assimilable nitrogen (YAN) responses across a wide range of vine N status at both sampling times. Leaf blade N was a better predictor than petiole N in predicting YAN using data sets from both the pot-in-pot vineyard and commercial vineyards. Relationships between leaf blade and petiole concentrations of P and K and vine response variables generally did not differ and both tissues appeared to be equally effective in predicting P and K effects on growth, yield, and must P or K levels. Although petiole P was slightly better than leaf blade P at bloom in predicting must P levels, and models including both leaf and petiole K simultaneously as predictors relied only on leaf K. For all three nutrients, sampling at bloom and veraison had a similar predictive strength for response variables. Based on these findings, we recommend using leaf blades as opposed to petioles for diagnosing the N, P, and K status of ‘Pinot noir’.

“…Most of the calculated ratios in petioles at bloom were negatively correlated with bunch weight, while Ca to Mg ratio calculated in petioles in bloom and véraison were correlated with plant yield. Previous studies showed that the accumulation of Ca is synergistic to Mg and that Ca + Mg to K ratio was negatively correlated with yield (Muthukrishnan and Srinivasan 1974;Assimakopoulou and Tsougrianis 2012). Low pH in soils increase K availability and enhance its uptake while reducing uptake of Ca and Mg (Centinari, 2018).…”

Nova Scotia is characterized by cold climate and acidic soils and high organic matter for viticultural development. There is little scientific information available about the nutritional management of grapevine varieties cultivated under cold climate conditions even in Nova Scotia. This study carried out in three seasons aimed to find correlations between tissue nutrients with yield and must composition in order to provide better nutritional management for a given variety. The yield of “L’Acadie” variety was correlated with B, K and Mg. In this variety, Ca to Mg ratio could be an interesting indicator of yield. The yield of “New York Muscat” variety was correlated with Zn, while N, P and K was related to bunch weight and weight of berries. Interspecific hybrids presented lower accumulation of B in their tissues than V. vinifera varieties. Zn and Fe were found as determinant micronutrients in “Chardonnay” variety. “Riesling” variety accumulated high levels of K in their tissues even over the optimal values recommended for grapevines. K to Ca ratio could be an important indicator of yield in “Pinot Noir” variety. A strong correlation between the petiole and blade analysis was found in macro and micro-nutrients. These results may contribute to improve the nutritional management of grapevines grown under cold climate conditions, mostly in Nova Scotia.

“…A strong correlation between K grapevine nutritional status and must attributes has also been observed. Excess K levels in grape berries can result in a high juice pH, with a detrimental impact on wine quality (Mpelasoka et al, 2003;Fogaç a et al, 2007;Assimakopoulou and Tsougrianis, 2012;Cuéllar et al, 2013).…”

Guidelines for fertilizer use in vineyards based on nutrient content of grapevine parts

a b s t r a c tPlant analysis plays a major role in fertilizer recommendations for perennial tree crops and vines. Plant analysis, however, does not quantify the rate of nutrients to apply. The approach developed in this work takes into account the content of the nutrients in grapevine parts and their dynamic within the plant to assist in the estimation of the amount of fertilizer to apply. Groups of three vines were cut at ground level on four different dates from September 14th to November 28th. On the first sampling date the vines were separated into trunk, cordons, canes, leaves and clusters for determination of dry matter content and elemental composition. On the following dates the vines were separated into the plant parts that were still present, since the clusters were only present on the first sampling date and the leaves on the first two. To assess the mobility of nutrients within the plant, samples of phloem vessels and sawdust of the entire trunk were taken as well as samples of chlorotic and green leaves. Nitrogen (N), potassium (K), phosphorus (P) and boron (B) showed mobility within the plant whereas calcium (Ca) and magnesium (Mg) did not. The removal of nutrients in clusters is critical for estimating N and K fertilizer rates. Clusters removed 19.9 kg N ha −1 and 28.7 kg K ha −1 . In the case of N, it is also important to assess the system's ability to recycle the nutrient contained in the leaves and canes which amounted to 49.4 kg N ha −1 . Phosphorus, calcium and magnesium applications might not justify being taken into account in the annual fertilization plan. Thus, the establishment of the fertilization programme should be a nutrient-specific exercise which takes into account all sources of information, including target yield and nutrient content in clusters, the vineyard management strategies influencing nutrient use efficiency from fallen leaves and prunings and soil testing and plant analysis.
