“…Error bars are the mean standard deviations containers with perlite and without K application. Previous studies carried out in the region with other crops, in field and in pots, revealed also that is difficult to obtain a positive response in crop growth or yield to the application of K (Arrobas et al 2017;Afonso et al 2018). In these experiments, probably soil K levels and leaf K concentrations were never low enough even in control treatment to significantly affect the performance of the trees.…”

Although potassium (K) is a macronutrient few studies have evaluated the response of olive tree to K fertilization. In this work results of two field and two pot K fertilizer experiments are presented. One of the field trials was conducted in a commercial young olive grove. The second was conducted in a plantation purposely established for this study. In the two field and the first pot experiment, the K supply was the single variation factor. The second pot experiment was arranged as a factorial with two K rates, two water regimes and two cultivars ('Arbequina' and 'Cobrançosa'). K supply did not increase olive tree growth or yield. Accumulated olive yield in the first field experiment, for instance, varied from 2.46 and 2.84 kg tree -1 , respectively in K treated and untreated plants. K supply increased the shoot/root ratio (1.6-2.0 from the control to the most fertilized treatment) and the concentration of K in roots (2.9-11.2 g kg -1 ) to a greater extent than in leaves (7.0-11.9 g kg -1 ), suggesting that shoots are a priority sink for K and roots may store the nutrient as a reserve. Plant water status and chlorophyll a fluorescence were not significantly affected by K applications. Plants suffering from water stress yielded less phytomass (40.2-56.4 g pot -1 , respectively in control and well-watered plants) and showed higher K concentrations in leaves (14.2-11.6 g kg -1 ) and lower in roots (4.9-6.8 g kg -1 ) which is probably due to the reduction of K uptake from the dry soil. 'Cobrançosa' appeared to be more tolerant to water stress than 'Arbequina'. These experiments showed a poor response of olive tree to K fertilization. Considering that K is usually applied by farmers every year, it seems that further studies on K fertilization in olive are needed in order to adjust K fertilizer rates to crop needs.

“…This result was not corroborated by our data, although the application of B to the soil has contributed to a significant increase in the concentration of B in leaves. However, B deficiency is a nutritional disorder widespread in the region among dicots (Arrobas et al, 2010(Arrobas et al, , 20172018;Rodrigues et al, 2011) and in several other parts of the world (Shorrocks, 1997;Fageria et al, 2002). In situations of deficiency, B can negatively affect plant growth and yield, as it plays a central role in the formation and functioning of the cell wall and can affect several metabolic pathways, such as amino acid and protein metabolism and the regulation of the supply of auxins and polyphenols (Broadley et al, 2012).…”

“…In these conditions, foliar sprays could be a complemental strategy to improve the nutritional status of trees, since previous studies on irrigated almond have shown that foliar sprays applied at post-harvest can enhance flowering in the following spring (Nyomora and Brown, 1999;Saa et al, 2017). N and B deficiencies are two major nutritional disorders affecting tree crop growth and yield, as reported from other important tree crop species grown across the Mediterranean basin, such as olive (Arrobas et al, 2010;Rodrigues et al, 2011), chestnut (Arrobas et al, 2017(Arrobas et al, , 2018 and pistachio (Weinbaum et al, 1994;Güneş et al, 2010). Thus, the objective of this work was to evaluate the almond tree response to the application of N or B to the soil with and without supplementation of foliar N or B sprays under rainfed conditions.…”

Rainfed orchards have huge social importance in territories of low agro ecological potential. Research on almond is limited for dry-farmed orchards in particular for crop nutrition and fertilization. This makes difficult to implement a cropping practice adjusted to the ecological constraints of these agrosystems. It is known that nitrogen (N) and boron (B) are determining nutrients for dicot tree crops such as olive and vineyards grown under these environmental conditions. Thus, this study aims to test at what level the crop responds to soil-applied N and B, and whether the foliar sprays can supplement or replace the application of the nutrients to the soil. It is also important to check if the sufficiency ranges set for the almond, which have been based on irrigated orchards, are adjusted for rainfed farming. The N rates applied to the soil were 0 (N0), 25 (N25), 50 (N50) and 100 (N100) kg hm −2 and those of B 0 (B0), 1 (B1), 2 (B2) and 3 (B3) kg hm −2. The foliar sprays consisted of three annual applications of N (two in 2017) and two applications of B (one in 2017), the last ones of 2015 and 2016 applied at post-harvest. Foliar N and B sprays were respectively applied at the concentrations of 0.5% N and 0.036% B. The experiment was arranged as a split-plot design with soil applied N or B assigned to the main plots and foliar N or B as subplots. Kernel yield showed a marked alternate-fruiting, with two years of good crops (2015 and 2017) and a year of practically no production (2016), likely due to adverse ecological conditions for almond growth and cropping practices incorrectly performed. Soil-applied N significantly increased kernel yield in comparison to the control but the differences were not significant in N rates higher than 25 kg N hm −2. The application of B to the soil improved tissue B concentrations but did not increase productivity. In general, foliar applications of N or B failed to improve plant nutritional status and kernel yield. The current sufficiency ranges for almond seem to be unnecessarily narrow for several nutrients such as N, potassium (K), calcium (Ca), manganese (Mn) and iron (Fe), since several results were found to be out of the sufficiency range with no apparent negative consequences for the trees. The laboratories carrying out soil testing and plant analysis should take this into account in diagnosing the nutritional status of almond orchards.

“…The limit values of foliar Zn concentration were determined as 22-25 mg kg -1 and 15-80 mg kg -1 in some hard-shell nuts such as walnuts and hazelnuts, respectively (Kacar and Katkat 1998). In all locations, leaf Mn concentrations were determined above the limit values determined by the researchers (Arrobas et al 2017). The foliar Mn content ranged from 564.8 to 834.3 mg kg -1 in chestnut orchards.…”

Chestnut is a plant that is grown in limited areas in the world and is profitable for its producer. In spite of this, the determination of nutrient elements and fertilization studies in chestnut orchards are insufficient. This study was carried out to determine the mineral nutritional status of Anatolian chestnuts cultivated in Inegol (Bursa) by soil and leaf analysis. In this research, the soil samples were taken from 25 different chestnut orchards (5 locations) in Inegol district only in April 2012. The chestnut leaves were sampled both in August 2012 and 2013. During both years, chemical and organic fertilization have not been done in the chestnut orchards. In soil samples, texture, pH, total salt, lime (CaCO₃), organic matter, total nitrogen, available phosphorus, potassium, calcium, magnesium, iron, zinc, manganese, and copper; In the leaf samples, macro and micro plant nutrient elements were analyzed except boron. The results of the analysis of the leaves and soil samples were compared with the limit values and the nutrient status and nutritional problems of the studied orchards were determined.According to the results, it was determined that the analyzed soils were the mostly coarse-textured, less salty, slightly acidic reaction and inadequate to organic matter and lime. In addition, N, Ca and Mg contents of the soil is very low, the P content is at the limit values and K, Fe, Zn, Mn, and Cu contents were found to be within the limit values. Also, leaf analysis results show that the plant's nutrients (N, P, K, Ca, Mg) are inadequate or below the limit values. However, the contents of micronutrients (Fe, Zn, Mn, Cu) remained within their limits.As a result, chestnut trees must be fertilized with macro nutrients for efficient and profitable production.
