“…7). Similar trends were previously reported for grapevines (Čuš, 2004;Somkuwar & Ramteke, 2006;McDonnell, 2011;Akin et al, 2012;Gamero et al, 2015;Senthilkumar et al, 2015 and references therein). This suggested that the combined effect of irrigation volume and ameliorant indirectly, i.e.…”

Sandy, gravelly or stony soils with low nutrient supply or plant available water are common in the table grape growing regions of South Africa. A field study was carried out to determine if an ameliorant recycled from waste glass could enhance the nutrient and water supply during the establishing phase of table grapes. Two grades of ameliorant, i.e. fine and coarse, were incorporated into the soil before the grapevines were planted. No ameliorants were applied to the control. After planting, the grapevines were irrigated by using 2.1 L/h drippers. To establish whether the ameliorants could compensate if less water is applied, the same treatments were applied under 1.2 L/h drippers. In general, the grapevines responded positively to the higher irrigation volumes, irrespective of ameliorant application. Where higher irrigation volumes were applied, the ameliorants did not have any positive effect on soil chemical or grapevine nutrient status compared to the control. This showed that the ameliorants were chemically inert under the given conditions. The ameliorants also did not improve grapevine water status, vegetative growth, yield or juice characteristics. Likewise, the ameliorants could not compensate for any measured aspect of grapevine performance where less irrigation was applied. In general, the ameliorants did not meet the expectations. Considering the additional costs of the ameliorant application, and the lack of positive grapevine responses, this practice cannot be justified under the given, or comparable conditions.

“…In fact, roots can adjust their development strategy, playing an essential role in plant performance during abiotic stresses [31,32]. Nitrogen is the most abundant nutrient and it directly affects grapevine growth [33][34][35][36][37]. It is widely known that an important adaptive strategy for plants subjected to nitrogen deficiency is root elongation.…”

Nitrogen (N) deficiency causes a morphological disequilibrium between shoots and roots, favoring hypogeal growth. Our hypothesis is that short-term nitrogen deficiency could induce an increase in vine resilience, inducing root growth before the appearance of significant dysfunctions in the epigeal part of the plant. Then, nitrogen availability could be promptly restored through a well-thought-out fertilization plan. In this experiment, two table grape cultivars grafted onto three different rootstocks were studied in three hydroponic growing conditions characterized by different nitrogen availability. After 53 days of treatment, plant morphologies were described, and leaf photosynthetic pigments were quantified. The short-term nitrogen deficiency induced root growth, leading to significantly different proportions among the hypogeal and the epigeal parts, despite no significant differences were recorded concerning shoot growth. Some small differences in the leaf pigmentations indicated an incipient symptom of nitrogen deficiency, and significant differences in the phytomer morphology indicated the possibility of developing low-cost indices for prompt identification of incipient symptoms. This will allow the exploitation of the advantages of short-term nitrogen deficiency while avoiding negative effects on shoot growth by promptly restoring the nitrogen availability.

“…Nitrogen is the major nutrient affecting grapevine vigour and must quality (Brunetto et al, 2007;Akin et al, 2012;Pérez-Álvarez et al, 2013). The addition of K can increases grape yield, as the result of increased cluster number and weight (Amiri and Fallahi, 2007).…”

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.
