Although the morphological descriptions of the white pulp (<i>H. undatus</i> Haworth) and red pulp (<i>H. polyrhizus</i> Web.) dragon fruits have been recorded using the BBCH scale, there is little knowledge about the phenology of the pink pulp dragon fruit, <i>Hylocereus costaricensis</i> (Web.)

This three-digit number system helps to standardize its phenological stages. Seven main growth phases have been identified: bud initiation (stage 0), shoot development (stage 3), development of primary shoots (stage 4), floral bud initiation (stage 5), flowering (stage 6), fruit development (stage 7) and fruit maturity and harvest (stage 8). There are now 40 distinct secondary growth stages that have been defined and documented. Because it describes all the phenophases related to vegetative and reproductive phases of dragon fruit, the enlarged BBCH scale is widely relevant. The scale can be used for the characterization of germplasm and to assess the effect of climate change on the phenology of dragon fruit. This important phenological stage scale may be utilized in growth, development and physiological studies besides usage in calculating heat unit requirements for different phenological stages. This BBCH scale can be utilized for effective management of orchards, standardization of propagation methods, intercultural operations, water and nutrition management, judging maturity standards for harvest, post-harvest shelf life and integrated pest and disease management.</p>","PeriodicalId":11889,"journal":{"name":"Erwerbs-Obstbau","volume":"98 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141883498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results revealed that the yield of trees was significantly affected by different nitrogen forms. Compared with nitrogen applied through other sources, nitrogen applied through slow-release resulted in the highest yield and good fruit quality. The slow-release application ultimately resulted in the highest total average yield (4.05 t/feddan) and the lowest cost (561.73 LE/t fruit). The average cost of fertilizing granular ammonium nitrate, ammonium sulphate, and urea to produce one ton of Persian lime fruit was 975.32, 1106.01, and 607.85 LE/t, respectively. Urea-derived nitrogen had the greatest impact on fruit weight and increased fruit diameter and juice percentage, followed by slow-release nitrogen and granular ammonium nitrogen in both seasons. The nitrogen source also affected the colour, lightness, and hue angle of the Persian lime peel. In light of these results, it can be concluded that using N slow-release fertilization for Persian lime trees grown in sandy soil is a good choice for reducing the number of applications annually, reducing the production cost, and improving the efficiency of nitrogen used by the trees to obtain a high yield with good fruit quality.</p>","PeriodicalId":11889,"journal":{"name":"Erwerbs-Obstbau","volume":"188 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141862683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This significance underpinned our comprehensive study, which aimed to dissect the relationships between <i>‘terroir’</i>, including the altitude, regional climate, soil characteristics, vineyard management practice, and the composition of grapes in cv. ‘Kalecik Karası’ (<i>Vitis vinifera</i> L.). Six vineyard sites ranging from 115 to 1180 m altitude were studied. Total soluble solids (TSS, °Brix) titratable acidity, pH and color index of red grapes (CIRG) were evaluated as the main maturity indices and phenolic composition based on anthocyanin and tannin was analyzed. According to the results of the study, we deduced the critical importance of adopting region-specific viticultural practices tailored to the unique environmental conditions of each <i>terroir</i>. This approach not only optimizes grape quality but also accentuates the uniqueness of the wines produced, reflecting the inherent qualities of their origin. The highest altitude Nevşehir (1180 m) showed high levels of total and extractable anthocyanin highlighting the region’s favorable conditions for these compounds (355.26 mg kg⁻¹ and 364.00 mg kg⁻¹), while exhibiting the second lowest skin tannin (1979.40 mg kg⁻¹ and 2180.78 mg kg⁻¹) in both years. Particularly for cultivars like ‘Kalecik Karası’, our study demonstrated how specific <i>terroirs</i> could significantly affect their phenolic composition and, consequently, wine quality. By aligning viticultural practices with the distinct characteristics of each <i>terroir</i>, producers can enhance both the quality and distinctiveness of their wines. This emphasizes the necessity of ongoing research and adaptation in viticultural strategies to fully harness the potential of diverse grape varieties and <i>terroirs</i>, ensuring the production of high-quality wines that truly reflect their origin.</p>","PeriodicalId":11889,"journal":{"name":"Erwerbs-Obstbau","volume":"1 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141777892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Field trials were conducted in Austria, Germany, and Italy. Weed coverage and biomass were assessed after the application of the mulch material and common in-row weed management practices, namely, herbicide use and mechanical weeding. The present trials showed that the mulch material is largely able to reduce weed growth at a rate comparable to herbicide use and mechanical weeding. The strongest effect on weed coverage was observed shortly after its application (three to four weeks) with a reduction of 83–97% compared with the untreated control. The greatest reduction in biomass was observed in May and June (83–99%). Weed growth then increased to varying degrees depending on the site.
