The presence of a sarcotesta plays a leading role in causing hindrances in this regard. Hence, the purpose of this study was to examine the combined effects of seed stratification at 7–8 <sup>0</sup>C and seedling administration with cycocel with regard to papaya germination, growth, and development. Vermicompost, coco peat, and garden soil were combined to create the potting media. A total of 11 treatments made up the experiment, which combined varying stratification times (measured in days) with multiple cycocel concentrations (measured in ppm) in the seedlings that germinated. The experiment was designed using the completely randomized design (CRD) statistical method, with three replications of each treatment. Several characteristics of the papaya seedlings were noted and examined during their developmental stage. In terms of germination percentage, the entire study indicated that seed stratification for 20 days and then cycocel application at 100 and 200 ppm were the most promising with a value of 86.67% in each case. After 10 days of seed stratification and 800 ppm of cycocel application, the overall quantity of leaves was noticeably higher (9.00 leaves). For the same 10-day stratification period, the maximum leaf length measured was 6.67 cm; however, 200 ppm of cycocel was applied. Following a 10- and 20-day stratification process, the application of 300 ppm of cycocel resulted in higher end values for the number of roots (34.67 for both combinations); however, the treatments had no effect on root length, as the control group recorded the highest mean value (9.27 cm). Lastly, the maximum accumulation of chlorophyll was demonstrated by a 20-day stratification period and a 600-ppm cycocel application (0.360 mg g<sup>−1</sup>). Thus, based on the study, we can conclude that the employment of cycocel and stratification have proven to be beneficial techniques for papaya seed development.

The aim of the study was to assess the economic and environmental effects of land fragmentation on hazelnut farming in Türkiye. The primary data for the study were collected through face-to-face questionnaires from 121 randomly sampled hazelnut farms. The partial budgeting analysis method was used to estimate the economic performance of the hazelnut farms. The environmental impact of land fragmentation in hazelnut farming was assessed using the life cycle assessment (LCA) method. The study revealed that the average production cost per hectare was US$ 1834.0 in fragmented farms, compared to US$ 1661.2 in non-fragmented farms. The hazelnut production cost per kilogram in the fragmented farms was 20.18% higher than in non-fragmented farms. The higher share of variable costs in the total production costs of fragmented farms was due to increased hired labor costs. Economic performance indicators, including GDP, gross profit, net profit, and relative profit, were lower in fragmented farms compared to non-fragmented farms. The LCA results showed that hazelnut production emitted 618.60 kg of CO<sub>2-eq</sub> of greenhouse gas (GHG) per hectare in 1 year. Additionally, producing 1 kg of hazelnuts emitted 0.4495 kg CO<sub>2-eq</sub> of GHG emissions. For non-fragmented farms, the GHG emissions per kilogram of hazelnuts were 0.4780 kg CO<sub>2-eq</sub>, while in fragmented farms, it was 0.5342 kg CO<sub>2-eq</sub>. This represented an 11.74% increase in GHG emissions for fragmented farms. The significantly lower GHG emissions in non-fragmented farms were mainly due to differences in chemical fertilization and farm manure application. In contrast, fragmented farms showed a larger machinery-related contribution and a more pronounced impact of diesel usage on emissions. The study concluded that addressing land fragmentation on hazelnut farms would enhance their economic performance. GHG emissions can be mitigated by improving agricultural practices, optimizing machinery and fuel use, enhancing chemical management, reevaluating farm structures, and raising climate change awareness.</p>","PeriodicalId":11889,"journal":{"name":"Erwerbs-Obstbau","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142182880","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}
