The objective of study was to investigate the effects of elevated CO<sub>2</sub> and temperature on carbon allocation and partitioning in different parts of plant, soil, and microbial biomass. An experiment was conducted on summer rape (<em>Brassica</em> <em>napus</em> L.) under increased levels of air temperature and atmospheric CO<sub>2</sub> in controlled environment chambers. Results showed that the amount of leaf, stem and root carbon statistically significantly increased under elevated CO<sub>2</sub> and temperature conditions. Microbial biomass carbon significantly increased by 11.2% and 13.5% under elevated CO<sub>2</sub> and elevated CO<sub>2</sub> and temperature, respectively, although soil carbon under both treatments decreased. It is concluded that carbon allocation is controlled under different climate conditions; however, elevated CO<sub>2</sub> and temperature together will have a more significant effect for carbon allocation to different plant parts and microbial biomass carbon compared to elevated CO<sub>2</sub> alone.</p> Gintarė Juozapaitienė Austra Dikšaitytė Gintarė Sujetovienė Jūratė Aleinikovienė Romualdas Juknys ##submission.copyrightStatement## 2019-03-11 2019-03-11 28 1 1–8 1–8 10.23986/afsci.70460 Impact of land use change on organic carbon sequestration in Arenosol https://journal.fi/afs/article/view/69641 <p>Conversion of arable soils into other land uses can stabilize and increase accumulation of soil organic carbon (SOC) and in addition prevent deterioration in its properties. The data has shown changes in SOC sequestration in Ap horizon after arable land conversion (1995–2015) into managed grassland, abandoned and pine afforested. SOC in Arenosol topsoil was positively affected by long term fallow and conversion into grassland. Abandoned land and fertilised managed grassland accumulated significantly more SOC, 48% and 38% respectively compared with arable land. In unfertilised managed grassland SOC stocks decreased 2.3% during 21 years, but losses were lower than in fertilised arable land. Pine afforestation of loamy sand helped to reduce the intensity of SOM mineralization compared to arable land. The Ap horizon thickness in pine forest soil increased from 28 to 31 cm during 21 years period. However, SOC stock decreased by 1% due to reduction in carbon concentration.</p> Asta Kazlauskaite-Jadzevice Liudmila Tripolskaja Jonas Volungevicius Eugenija Baksiene ##submission.copyrightStatement## 2019-03-11 2019-03-11 28 1 9–17 9–17 10.23986/afsci.69641 The effect of different proportions of Medicago media Pers. in mixtures with Festulolium braunii (K. Richt.) A. Camus on the yield and feed value of green fodder https://journal.fi/afs/article/view/77222 <p>A field experiment was performed in 2011–2013. The aim of the study was to determine the effect of different proportions of <em>Medicago media</em> in mixtures with <em>Festulolium braunii</em> on the yield and feed value of green fodder, including the content of crude protein (CP) and water-soluble carbohydrates (WSC), and the carbohydrate-to-protein ratio. It was found that alfalfa had a high competitive advantage over <em>Festulolium</em>. In the second and third year of full utilization, alfalfa was the predominant species in the tested mixtures regardless of the proportion of sown seeds. The mixtures with alfalfa were characterized by high and stable dry matter yields and high protein content, whereas <em>Festulolium</em> significantly increased the content of WSC and improved the WSC:CP ratio. The evaluated mixtures had a higher feed value than pure-sown components. The results of the study indicate that <em>Festulolium</em> mixtures with a lower proportion (30% and 50%) of alfalfa are characterized by a higher feed value.</p> Marzenna Olszewska Stefan Grzegorczyk Anna Bałuch-Małecka ##submission.copyrightStatement## 2019-03-27 2019-03-27 28 1 18–26 18–26 10.23986/afsci.77222 Changes in yield and nutritive value of red clover (Trifolium pratense L.) and Festulolium (Festulolium braunii (K. Richt) A. Camus) under drought stress https://journal.fi/afs/article/view/73282 <p>The aim of the research was to assess the impact of water stress on the yield and content of basic nutrients in the biomass of <em>Trifolium pratense</em> and <em>Festulolium braunii</em> cultivated in pure stand and in mixture. A pot experiment was carried out in 2012–2014, at two levels of soil moisture: well-watered and drought stress. The study showed that stress significantly reduced the dry matter yield (DMY), the most in <em>T. pratense</em>, followed by mixture, and <em>F. braunii</em>. The effect of drought stress on the nutritive value was considerable less pronounced than the influence on DMY. No significant influence of water deficit on crude protein, crude fibre and crude ash contents was found, but only on water-soluble carbohydrate and crude fat content in one year of the study. It was found, that under drought stress <em>T. pratense</em> is more suitable for cultivation in the mixture with <em>F. braunii</em> than in pure stand, due to a lower reduction of DMY and no adverse effect of water deficiency on yield quality.</p> Mariola Staniak ##submission.copyrightStatement## 2019-03-27 2019-03-27 28 1 27–34 27–34 10.23986/afsci.73282 Impact of ozonation process on the microbiological and antioxidant status of raspberry (Rubus ideaeus L.) fruit during storage at room temperature https://journal.fi/afs/article/view/70291 <p>In this study the effect of the ozonation procedure on the microbiological and antioxidant status of raspberries stored at room temperature was investigated. During the study, it was found that ozonation with a dose of 8–10 ppm for 30 min, every 12 hours, for 3 days effectively reduced the growth of aerobic mesophilic bacteria and fungi. On the last day of storage, infestation with <em>Botrytis cinerea </em>for control fruit amounted 100%, while for ozonated fruits it was only 12%. In addition, the ozonation process has preserved the high antioxidant potential of the fruits and reduced the loss of polyphenol compounds, including anthocyanin. The applied procedure was proven to be effective, showing the potential of ozone as a factor extending the high commercial and consumer value of fruit stored at room temperature.</p> Tomasz Piechowiak Piotr Antos Patryk Kosowski Karol Skrobacz Radosław Józefczyk Maciej Balawejder ##submission.copyrightStatement## 2019-03-27 2019-03-27 28 1 35–44 35–44 10.23986/afsci.70291 Invasion potential of herbaceous ornamental perennials in northern climate conditions https://journal.fi/afs/article/view/77398 <p>We studied invasion potential of perennial herbaceous ornamental plants in Finland by using their reproduction success as an indicator. Altogether, 220 clones from 166 species were included in the studies. In common gardens, 50% of the species were found to produce seedlings and 75% rhizomes, respectively. Twelve of the clones produced neither seedlings nor rhizomes. Rankings of the invasion potential based on the two reproduction modes did not correlate. The species known for their invasion potential in temperate or cool climates were among the highest ranking seedling producers in the common gardens. In the field experiment, the highest seedling production (73%) was found in the semi-dry moisture regime, followed by the dry (40%) and the moist (27%) regimes. In the greenhouse experiment, 83% of the studied clones and 84% of the species emerged. Temperature sum required for the production of viable seeds for one third of the studied species is reached at least every second year in latitudes 62–63°N. Several perennial herbaceous ornamentals have potential for northward range expansion.</p> Timo Kaukoranta Sirkka Juhanoja Eeva-Maria Tuhkanen Terho Hyvönen ##submission.copyrightStatement## 2019-03-29 2019-03-29 28 1 45–57 45–57 10.23986/afsci.77398 Acknowledgements https://journal.fi/afs/article/view/80101 <p>Agricultural and Food Science expresses its sincere thanks to the referees for their constructive critical reviews of one or more manuscripts during the year 2018.</p> Tuula Puhakainen ##submission.copyrightStatement## 2019-03-29 2019-03-29 28 1 58 58 10.23986/afsci.80101
