“…Table 7 shows also that each cultivar within each farm has a different nutrient concentrations, in spite of every farm received equal rates of fertilization and type. These results agrees with the studies of Jordao et al (1999) and Saidana et al (2009). It could be concluded from these results that all farms suffer from nutrient imbalances, which differ according to cultivar.…”

A study was conducted during 2014 to 2015 seasons on olive orchards; cultivars (Koroneki, Dolce and Manzanillo) grown on sandy soil under drip irrigation and irrigated with different levels of water salinity from 0.95 to 4.3dS/m-1 , in various locations in Cairo-Alexandria road, to evaluate the nutritional status through soil testing and leaf analysis. The soils had very high pH and low organic matter, potassium, iron and manganese, different levels of EC, CaCO 3 , P, Na concentrations ranged between low and high, and different levels of Ca, Mg, Zn and Cu ranged between low and medium. Significant negative correlation was found between pH and Zn in soil. In olive leaves, the levels of N, P, Na, Fe and Cu concentrations ranged between low and high, K and Ca concentrations were between low and sufficient; Mg, Mn and Zn concentrations were sufficient. A highly significant positive correlation between leaf Mg concentrations and yield was found. Olive trees showed that minerals of needle ranked from greatest to least as K > Ca > Mg indicating that olive trees have more ability (preferability) to take up K in higher quantities than Ca and Mg. Olive varieties differ also in ability (preferability) to take up micronutrients.

Effects of nitrogen fertilization and nitrification inhibitor product on vegetative growth, production and oil quality in ‘Arbequina’ hedgerow and ‘Picual’ vase-trained orchards

2018

SUMMARY:Two experiments were carried out in olive orchards in the center of Spain over a three-year period. In this cold and dry area, growers traditionally apply large amounts of N with no experimental knowledge. An 'Arbequina' hedgerow and 'Picual' vase orchards were fertilized with two N-doses applied to the soil in spring with or without the nitrification inhibitor (DMPP). Vegetative growth, fruit and oil characteristics were evaluated. These variables were affected by the N-treatment during the 3 rd year. The lowest N-application increased vegetative growth, while when N-leaf composition was higher than 2%, fruit dry weight, oil content and oil phenol content were reduced. 'Picual' did not respond to N-applications. The effect of DMPP on growth or production was not consistent and a lower phenolic content was obtained for 'Arbequina'. Our results demonstrated that in this dry land, N-fertilization is not always necessary and oil quality can be negatively affected with high doses. KEYWORDS: Leaf analysis; Oil quality; Olea europaea L.; Olive fertilization; Phenolic compounds; Reproductive componentsRESUMEN: Efectos de la fertilización nitrogenada y del inhibidor de la nitrificación sobre el crecimiento vegetativo, la producción y la calidad del aceite en olivares 'Arbequina' en intensivo y 'Picual' en vaso. Durante tres años, se llevaron a cabo dos experimentos en olivares del centro de España. En esta fría y seca zona de cultivo, los agricultores aplican grandes cantidades de nitrógeno sin ningún criterio. Un olivar de 'Arbequina' en intensivo y otro de 'Picual' en vaso se fertilizaron con dos dosis de N aplicado al suelo en primavera con o sin el inhibidor de la nitrificación 3.4 dimethyl phyrazol phosphate (DMPP). El tercer año, el N afectó al crecimiento vegetativo y a las características del fruto y del aceite. La menor dosis de N aplicada, aumentó el crecimiento, pero cuando la composición de N en hoja fue superior al 2%, el peso del fruto, el contenido en aceite y el contenido fenólico se redujeron. 'Picual' no respondió al N. El efecto del DMPP en el crecimiento o la producción no fue consistente y afectó negativamente al contenido fenólico del aceite en 'Arbequina'. Nuestros resultados demuestran que en esta árida zona la fertilización con N en olivo no siempre es necesaria y la aplicación de dosis elevadas de N puede afectar negativamente a la calidad del aceite.

“…In this study, plant morphology and leaf gas exchange parameters (P n , g s and E) from the 2.8 and 5.6 g/tree N were statistically similar. It has been shown that morphological traits such as leaf area and leaf dry weight are vulnerable to N availability (Saidana et al, 2009). A hydroponic study for growth analysis using olive seedlings also confirmed the negative effects of nutritional stresses on dry matter, chlorophyll concentration, and higher stomata resistance (Saidana et al, 2009).…”

A hydroponic study for growth analysis using olive seedlings also confirmed the negative effects of nutritional stresses on dry matter, chlorophyll concentration, and higher stomata resistance (Saidana et al, 2009). Consistent with the reports showing reduced yield and leaf N content in the orchards receiving no nitrogen (Rodrigues et al, 2011b), in this study the plant morphological components and P n from untreated control plants were significantly lower than N-treated plants.…”

The impact of nitrogen application on the growth of olive trees has been well studied. However, little is known about the role of levels and forms of N on the development of roots and physiological traits during establishment of young trees. The objective of this 2-year study was to evaluate the influence of N source and level on shoot morphology (tree height, stem diameter, and branch number) and physiology [leaf area and fresh weight, photosynthesis (Pn), transpiration (E), and stomatal conductance (gs)], root components (length, diameter, surface area, and fork number) and N content of young olive (Olea europaea cv. Arbequina) cuttings. Three-month-old olive cuttings were planted in 15-L pots filled with a growing substrate composed of peatmoss + bark + sand (2:1:1/by volume) and placed in a screen house. Two N levels, 2.8 and 5.6 g/tree, and control (0 N) and four N sources, calcium nitrate (CN, 12%N, 17%Ca+2), ammonium nitrate (AN, 35%N), urea (46%N), and the slow-release Osmocote (OSC, 18%N, 6%P, 12%K) were evaluated. Effects of low– (2.8 g/tree) and high N (5.6 g/tree) levels on shoot components (plant height, diameter, branch number, leaf area, and fresh weight) and gas exchange (Pn, gs and E) were similar implying that the low rate of N was adequate for the establishment of young olive cuttings. Nitrogen sources, particularly AN and CN had significant effects on shoot and root morphology, physiology, and leaf and root N concentration. In fact, AN and CN were the best fertilizer sources for olive transplants in term of root and shoot growth. Overall, 2.8 g/tree N level and AN or CN sources were the best treatments for newly established olive ‘Arbequina’ trees. Root components treated with high N rate (5.6 g/tree N) using the slow-release fertilizer (OSC) was similar to those treated with the low AN rate (2.8 g/tree N). Therefore, for nursery containerized olive trees of ‘Arbequina’ or other cultivars with comparable growth rates, we recommend to apply the CN or AN source at 2.8 g/tree N or the controlled-released fertilizer OSC at 5.6 g/tree N.
