Tartary buckwheat (Fagopyrum tataricum Gaertn.) and common buckwheat (Fagopyrum esculentum Moench.) plants grown in the field were treated foliarly with 126 μM solutions of selenate and/or sulphate ...in order to study the effect of sulphur (S) on selenium (Se) concentration in plants. In both species, the concentration of Se in all plant parts was similar in control and S treated plants. In Tartary buckwheat the concentration of Se was higher in S and Se treated plants than in plants treated with Se alone. S was shown to enhance Se accumulation in Tartary buckwheat. It was also shown that it is possible to produce grain and herb of Tartary and common buckwheat containing appropriate amounts of Se for food without affecting the yield of the plants.

ABSTRACT Basil (Ocimum basilicum L.) is an annual plant that belongs to the Lamiaceae family. It is used as an aromatic and medicinal plant. Basil is grown in different regions with varying climates; ...the productivity and quality are influenced by both abiotic and biotic factors. This study was aimed to determine the impact of the application of different types of fertilizers on the yield and contents of some bioactive components in basil. The treatments consisted of three different types of fertilizers (mineral, organomineral, and organic) and control (without fertilization). The yield per plant and the essential oil content with fertilizer treatment were better than that in control. The highest fresh yield (450.9 g per plant) and oil content (0.94 mL 100 g-1) were recorded in basil cultivated using mineral fertilizers. Furthermore, the fresh yield (333.9 and 327.8 g per plant) and oil content (0.87 and 0.85 mL 100 g-1) were higher after the application of organic and organomineral fertilizers compared to that in the control treatment. There was no significant effect of fertilizer application on the total phenolics, total flavonoids, and antioxidant capacity. This study demonstrated a suitable practical application of organomineral fertilizers as a nutrient source in basil crop production in areas where the use of mineral and organic fertilizers is limited.
RESUMO O Manjericão (Ocimum basilicum L.) é uma planta anual pertencente à família Lamiaceae. É usada como planta aromática e medicinal. O manjericão é cultivado em diferentes regiões com climas variados; a produtividade e a qualidade são influenciadas por fatores abióticos e bióticos. Este estudo teve como objetivo determinar o impacto da aplicação de diferentes tipos de fertilizantes na produção e conteúdo de alguns componentes bioativos de manjericão. Os tratamentos consistiram em três tipos diferentes de fertilizantes (minerais, organominerais e orgânicos) e controle (sem fertilização). O rendimento por planta e o teor de óleo essencial com tratamento de fertilizantes foram melhores do que o controle. O maior rendimento fresco (450,9 g por planta) e teor de óleo (0,94 mL 100 g-1) foram registrados em manjericão cultivado com o uso de fertilizantes minerais. Além disso, o rendimento fresco (333,9 e 327,8 g por planta) e teor de óleo (0,87 e 0,85 mL 100 g-1) foram maiores após a aplicação de fertilizantes orgânicos e organominerais em comparação com o do tratamento controle. Não houve efeito significativo da aplicação de fertilizantes em fenólicos totais, flavonóides totais e capacidade antioxidante. Este estudo demonstrou uma aplicação prática adequada de fertilizantes organominerais como fonte de nutrientes na produção de manjericão em áreas onde o uso de fertilizantes minerais e orgânicos é limitado.
Common buckwheat (Fagopyrum esculentum Moench.) has a long history of cultivation in the large, mountainous regions of Bosnia and Herzegovina (B&H). Its commercial production is mainly based on the ...regionally bred variety ‘Darja’, but numerous landraces are also being grown on a smaller scale. As part of the SEEDNet (Southeast European Network on Plant Genetic Resources) project, these landraces have been collected and stored at the Gene bank of the Faculty of Agriculture and Food Sciences in Sarajevo (FAFS). To assess their utilization value, it was first important to investigate if they represent distinct landraces and to identify their genetic relationships with the most commonly grown varieties in the region (‘Darja’, ‘Goluba’ and ‘Čebelica’). Therefore, the aim of this study was to assess the genetic relationships and diversity of the common buckwheat accessions maintained at the FAFS Gene bank, as well as the value of these accessions for future breeding programs, using microsatellite markers and seventeen quantitative and fifteen qualitative morphological traits. The FCA (Factorial Correspondence Analysis) and AMOVA (Analysis of Molecular Variance) revealed that several accessions represent completely distinct landraces which clearly differentiated from the most commonly grown cultivars ‘Darja’ and ‘Goluba’. Conducted morphological analyses revealed that several of the analyzed landraces hold similar characteristics to the ones observed in ‘Darja’ and ‘Goluba’, while others possess unique traits potentially useful in breeding programs.
In order to determine the influence of the sowing date on the most important agronomic sunflower traits, an experiment was conducted according to a random block design at the Osijek location. ...INTRODUCTION Sunflower (Helianthus annuus L.) is primarily grown because of the oil used in human consumption, but also as a raw material for the processing industry, animal feed, and beekeeping. Considering the occurrence of increasingly dry vegetation seasons, especially in the summer, with less precipitation, higher temperatures, extremely high daily maximums, but also fluctuations in weather parameters over a short period (daily, weekly) (Mijić et al., 2017; Jug et al., 2018), determination of the most favorable sowing date is a very important part of the application of quality agrotechnical measures (Balalić et al., 2007). ...this study aimed to determine the effect of sowing date on the most important agronomic traits of sunflower: plant height, head diameter, grain yield, oil content and oil yield of 25 sunflower hybrids at the Osijek location during 2015 and to identify the best hybrid combinations for further breeding work. According to Škorić (2012), the head diameter in sunflower hybrids is generally 20 to 30 cm.
S ciljem utvrđivanja utjecaja vremenskih uvjeta na komponente uroda ulja suncokreta, u radu su analizirani trogodišnji rezultati poljskih pokusa. U pokusima posijanim u Osijeku 2013., 2014. i 2015. ...godine bilo je 15 hibrida suncokreta: dva strana hibrida i 13 hibridnih kombinacija Poljoprivrednog instituta Osijek. U periodu prije sjetve (siječanj – ožujak), najveća je količina oborina bila 2013. (213,1 mm), zatim 2015. (167,9 mm), a najmanja 2014. (109,5 mm). U vegetacijskome periodu (travanj – rujan), u 2014. bilo je najviše oborina (487,3 mm), u 2013. 475,7 mm, a u 2015. najmanje (251,6 mm). U 2013. godini, u vegetacijskome periodu, srednja mjesečna temperatura zraka bila je 19,1°C, u 2015. 19,9°C, a u 2014. 18,6°C. Od navedenih godina, statistički značajno na nivou P=0,05, najviše vrijednosti analiziranih svojstava zabilježene su 2013. godine: urod zrna 6,47 t ha-1, sadržaj ulja 51,69% i urod ulja 3,05 t ha-1. Urod zrna, sadržaj ulja i urod ulja bili su manji 2015., a najmanji 2014. godine. Najveće vrijednosti uroda zrna i ulja (6,95 i 3,39 t ha-1) imao je Matej, novopriznati hibrid suncokreta Poljoprivrednog instituta Osijek, a po sadržaju ulja od 53,44% bio je na trećem mjestu. Za visoke urode zrna i ulja suncokreta, pored optimalne temperature zraka, jako je bitna količina i raspored oborina prije, a također i tijekom vegetacije.
With the purpose of determining the influence of weather conditions on the yield components of sunflower, the results of three-year field trials are analysed in the paper. In the trials sown in ...Osijek in 2013, 2014 and 2015, there were 15 sunflower hybrids: two foreign hybrids and 13 hybrid combinations of the Agricultural Institute Osijek. In the period before sowing (January – March), the highest amount of precipitation was in 2013 (213.1 mm), then in 2015 (167.9 mm), and the lowest in 2014 (109.5 mm). In the growing period (April – September), the highest amount of precipitation (487.3 mm) was in 2014, 475.7 mm in 2013, and in 2015 it was the lowest (251.6 mm). In 2013, during the growing period, the mean monthly air temperature was 19.1°C, in 2015 19.9°C, and in 2014 18.6°C. Of these years, statistically significant at the P=0.05, the highest value of the analysed traits was recorded in 2013: grain yield of 6.47 t ha-1, oil content 51.69% and oil yield 3.05 t ha-1. Grain yield, oil content and oil yield were lower in 2015, and the lowest in 2014. Matej, a newly recognized sunflower hybrid of the Agricultural Institute Osijek had the highest values of grain and oil yield (6.95 and 3.39 t ha-1), and by its oil content of 53.44%, it was in the third place. For high grain and oil yields of sunflower, in addition to the optimal air temperature, the amount and distribution of precipitation before and also during the growing season are very important.
According to FAO data (FAOStat, 2018), in 2016, it buckwheat was cultivated on an area of 2.37 million hectares globally. Yield of buckwheat also significantly depended on sowing rate and they are in ...a positive relation. ...the average grain yield in S1 variant was 0,81 t ha-1, and increased to 1,43 t ha-1 in S3 variant. CONCLUSIONS According to the presented results of the research, influence of meteorological parameters on the yield and chemical composition of common buckwheat during the seasons of 2011, 2012 and 2014, following conclusions can be reached: -the yield of buckwheat significantly depended on sowing rate and meteorological parameters; -Increasing sowing rate had positive effect on yield of kernel, but it had no effect on chemical compose of kernel; -second year of research was with unfavorable weather conditions (drought and high temperature) which resulted in low average yield; -contents of crude protein, starch and total phenol in kernel depended on meteorological parameters. -high content of protein and total phenols was recorded in the year with relatively unfavorable weather conditions; -drought at 2012 year significantly caused a reduction in contents of starch in kernel.
