In addition, while production costs increase, it also decreases in production areas. This study has been researched together with the usability of the drip irrigation method (DI) to reduce the global footprint of water in paddy production and its economic analysis. In the experiment, two irrigation intervals (2 and 4 days), four irrigation water levels (75, 100, 125 and 150% of cumulative Class A Pan values) and three different paddy genotypes (Baldo, Osmancik and Ronaldo) were investigated. In the research, irrigation water between 513-820 mm was applied to the treatments. Actual Evapotranspiration (ETa) values are 565-855 mm; The Crop Water Productivity (CWP) ranged from 0.84-1.35 kg ha-1 m-3 and the Irrigation Water Use Efficiency (IWUE) ranged between 0.95-1.49 kg ha-1 m-3. Economical water productivity (EWP) was calculated between 0.79-1.24 $ m-3 and the cost-benefit (B/C) ratio was calculated between 1.11-2.33. When the traditional cultivation method, the ponding method in the pan, is compared to the province, it has been determined that water savings are between 70-81%. Yield according to branches was measured as 4882-10305 kg ha-1. According to the results of the research, up to 29% yield increase was achieved under the condition of applying 150% of the cumulative evaporation every 2 days.","PeriodicalId":254664,"journal":{"name":"Current Trends in Natural Sciences","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114077161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During 2020-2021, the increase of the trunk cross-sectional area registered an average of 5.25 cm2 (0.02-21.19 cm2), and the fruit yield averaged 55.64 t/ha (0-166.98 t/ha). The mean values recorded for the fruit weight and pulp firmness, were 173.22 g (74.13-558.76) and 76.50 units Bareiss HPE-II-FFF (53.60-89.10), while the pH of the fruit juice and total soluble solids fluctuated around 3.55 (3.09-4.68) and 13.3 ⁰Brix (9.45-18.20). Foliar treatment with Cifamin BK (1.5 l/plant) significantly increased fruit yield by 49.5% compared to the untreated variant. Fruit weight increased in all three fertilization treatments on ´Decosta Jonagold de Coster´ and ´Red Braeburn´. Organic biostimulators and fertilizers improved pulp firmness on ´Golden Reinders Delicious´, juice pH on ´Decosta Jonagold de Coster´ and total soluble content on ´Red Braeburn´. The results of the study showed that, on the mineral nutrition background, Cifamin BK and Biohumus treatments in apple orchards improved fruit yield and quality.","PeriodicalId":254664,"journal":{"name":"Current Trends in Natural Sciences","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115959324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to investigate the relationship between the water supply levels and phosphorus and potash applications. The experimental design was a split plot design with three replications. The main plots were five irrigation levels (50, 70, 90, 100 and 120% of reference evapotranspiration (ET0)), while the sub- plots contained four fertilization treatments: control (T0), K2O (T1), P2O5 (T2) and K2O + P2O5 (T3). The obtained yields were 5.64, 5.37 and 7.87 t ha-1, during the three consecutive seasons. They were significantly affected by phosphorus apply (P <0.01) during the all trial seasons. No significant effect of potash was observed during the first season. Its effects were significant (P <0.05) and highly significant (P <0.01) during the second and the third season respectively. Water treatment effects were significant on yield and almost all its yield components. The highest water efficiency was recorded when water apply was close to 100 % of MET and elements N P K are available.","PeriodicalId":254664,"journal":{"name":"Current Trends in Natural Sciences","volume":"383 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116483052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The control methods of invasive species are often effective on the short term and include the probability of ecosystem imbalance over time, so that an efficient and sustainable management method that could add value to products or improve some industrial processes are strongly required. This study describes the potential of alien plants to maintain the quality of human life through different types of valorization, such as pharmaceutical, agriculture or food industry applications, energy production, paper technology and natural dyeing of various materials. Invasive plant species represent a global problem, accelerated by the current level of pollution and the rapidly-evolving society. Knowledge of chemical composition of different plant parts of invasive species, their potential for developing new products and their health effects will contribute to an efficient control, mechanical, chemical or biological, and an integrated management.","PeriodicalId":254664,"journal":{"name":"Current Trends in Natural Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131165667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taxus baccata L. is an evergreen non-resinous tree, often with multiple trunks and spreading, pyramidal or rounded canopy. It can be propagated generatively and vegetatively. Nurseries mostly prefer to propagate them by vegetative way, because this type of method is quicker and the newly propagated plants inherit the genetics of the mother plants. In this study we have selected two varieties of Taxus baccata `Repandens` (TBR) and T. baccata `Fastigiata Aurea` (TBF), in which different length stem cuttings (5–10, 10–20, and 20–25 cm) were obtained and propagated in two different periods (May and July). From our results could be concluded that TBR rooting percentage increased at the collected cuttings in May and at 10–20 cm size. On the other hand, at TBF cuttings rooting percentage reported significant increases at 5–10 cm, also at the cuttings collected in May. In conclusion, our research suggests that Taxus baccata cuttings could obtain a higher rooting percentage when they are collected in May, moreover the length of the cuttings could be an influencing factor.","PeriodicalId":254664,"journal":{"name":"Current Trends in Natural Sciences","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134459311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
