Summary: The results of the experiments indicated that there are differences in nitrogen uptake efficiency among olive cultivars. Certain cultivars such as 'Picual', 'Arbequina', 'Manzanilla de Sevilla' from Spain, 'Koroneiki' from Greece, and 'Frantoio' from Italy showed higher nitrogen use efficiency. Soil type did not have a significant impact on nitrogen uptake efficiency.

Summary: Nitrogen applications in orchards can meet the nitrogen demand of olive trees, but some nitrogen in the fertilizer may be taken up by ground cover plants such as Paspalum notatum. This study evaluated the recovery and distribution of nitrogen fertilizer by different olive cultivars and their intercropping with P. notatum. Results showed that the highest nitrogen recovery was observed in olive trees grown without P. notatum, and applied nitrogen mainly accumulated in the leaves and roots. P. notatum exhibited a strong ability to compete with olive trees for soil nitrogen, leading to decreased growth and nitrogen content in olive cultivars.

Summary: The study found that girdling treatment on olive mother plants has a positive effect on the rooting ability of cuttings, with autumn girdling showing better results compared to spring. Girdling enhances the rooting performance of cuttings and positively affects the concentration of polyamines, phenolic compounds, and soluble carbohydrates. More research is needed to draw conclusions on the overall efficiency of girdling on inducing rooting of olive cuttings.

Summary: This study presents an improved version of the OliveCan model, which can simulate the impacts of cover crops on the water and carbon balances of olive orchards. The effects of different cover crop widths and mowing dates on olive yield and soil water content were evaluated using simulations of a traditional olive orchard in southern Spain. The results showed that high cover crop width and late mowing could decrease olive yield, but their effects on soil water content and surface runoff were independent of the mowing date.

Summary: Understanding the quantity of inorganic fertilizer applied to different crops at national, regional and global levels is crucial for fertilizer consumption analysis and demand projection. However, accurate data on fertilizer use by crop is limited due to the challenges in collection and validation. To address this issue, expert surveys have been conducted regularly by international organizations such as FAO, IFDC and IFA, with the IFA dataset being the only globally available data on fertilizer use by crop.

Summary: In this study, 44 olive tree cultivars were evaluated for the phenolic profile of virgin olive oil (VOO), revealing significant variations in total phenol concentration among cultivars with the 'cultivar' factor contributing the most to the variance. The presence of three groups of cultivars with distinct phenolic profiles highlights the importance of considering phenolic composition in olive breeding programs.

Summary: This study compared the soil properties of traditional olive orchards on sloping and flat areas. It was found that the flat orchard had higher bulk density and penetration resistance compared to the sloping orchard. The oxygen diffusion rate was also higher in the sloping orchard. Both orchards showed insufficient nutrient levels. Overall, the use of no-tillage practices seemed promising for the sustainability of olives.

Summary: In sub-Saharan Africa, smallholder farmers rely on local fertiliser resources for soil fertility management. In Vilankulo, Mozambique, farmers have access to bat guano and biochar, but in limited quantities. A study was conducted in a haplic Lixisol to examine the impact of different treatments on maize yield. The results showed that treatments with higher levels of guano and biochar led to higher maize yields, while biochar did not significantly contribute to plant nutrition.

Summary: The aim of this study was to compare the effects of two leonardites (Humitec and Humic Gold) and an organic compost (Nutrimais) on lettuce compared to an untreated control. The experiment was conducted in NE Portugal in two seasons. The results showed that the growing season and NPK fertilization significantly affected lettuce dry matter yield (DMY). The organic amendment influenced nutrient concentration in plant tissues and some soil properties, but did not affect DMY. Nutrimais had a positive effect on DMY in the first growing season and in pots without NPK fertilization. Leonardites did not have any significant effect on soil properties, nutrient concentration, or DMY. The increase in lettuce DMY with organic compost was likely due to the supply of nitrogen, which is the most critical limiting factor for plant growth. Therefore, NPK fertilizer and Nutrimais, a compost with a low C/N ratio and nitrogen supply, had the greatest impact on lettuce DMY.

Summary: The KNOX gene plays crucial roles in plant development, and this study identified 19 KNOX gene members in kiwifruit. One of the genes, AcKNOX11, is selectively expressed in flower buds and shoots, and its expression can be induced by ABA and melatonin. Functional analysis revealed that AcKNOX11 delays flowering, reduces plant height, alters leaf shape, and inhibits seed germination through ABA-melatonin interaction.

Summary: Bagging is a crucial cultivation measure that affects the quality of peach fruit by regulating exposure to light. This study investigated the effects of bagging on the content of phenolic compounds in peach fruit and identified the most sensitive compounds to bagging treatment. The study also explored the regulatory role of bagging on phenolic synthetic-related genes. The results showed that bagging affected the accumulation of different phenolics in different peach cultivars and light intensity played a significant role in the accumulation of anthocyanins and other phenolic substances in peach fruit. Additionally, the expression of structural genes and transcription factors related to phenolic synthesis was regulated by bagging and light conditions. These findings provide a foundation for understanding the regulation mechanism of light on the synthesis of phenolic compounds in peach fruit.
