Common buckwheat (Fagopyrum esculentum Moench) is an annual plant from Polygonaceae family which is well known as pseudocereal with high nutritional value. The yield and quality of the buckwheat`s kernel depend on weather conditions, mainly due to variations in the air temperatures and precipitation during the growing period. The aim of this study was to determine the impact of some metrological parameters on yields and chemical compositions in the kernel of buckwheat. Field experiments were conducted during three years (2011, 2012 and 2013) in the village Donje Selo, near Ilijaš. In this study grain yield, protein content, sludge, fats, mineral matter, cellulose and total phenols were determined. Experimental results suggested that the weather conditions in different years of the research have a significant impact on the yield and the chemical composition of the kernel. The yield of buckwheat varied from the year to year and ranged from 0.98 to 1.29 tons per hectare. Contents of protein and starch were also significantly dependent on the year of the research, as well as the content of phenol in the kernel. High total phenolic content was recorded in the year with the highest average monthly air temperature.

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.

Lithuania and Bosnia and Herzegovina are considered as countries with high vulnerability and low adaptive capacity to cope with climate change. The entire territory of these countries is characterized by the warming trend, with positive trends in both the maximum and the minimum temperatures throughout the year. The increase in air temperature has resulted in change of evapotranspiration and mean annual water balance values. These countries are also frequently faced with an occurrence of severe droughts and heavy floods. The main purpose of this study was to determine and compare the severity of changes in mean annual water balance for two humid climatic zones, in order to understand how different areas of similar climate characteristics react to climate change and to analyze the significance of their influence. Monthly weather data from two weather stations, Kaunas (Lithuania) and Sarajevo (Bosnia and Herzegovina), for the time period of 30 years (1988 -2017) were used to determine and analyze the mean annual water balance. The results indicate that climate change has a different effect on the water balance of these two humid areas. Both locations showed a positive trend of reference evapotranspiration, with an increase of 1.450 mm year -1 to 1.503 mm year -1 . However, the total runoff and soil moisture deficit are decreasing in Kaunas (-0.480 mm and -2.114 mm year -1 , respectively), while they are increasing in Sarajevo (0.492 mm and 0.485 mm year -1 , respectively).

ANTIMICROBIAL ACTIVITY OF GINGER (Zingiber officinale) AND ROSEMARY (Rosmarinus officinalis) ESSENTIAL OILS SUMMARY New advances in the food industry are directed towards exploiting natural resources. Nowadays, essential oils and their antimicrobial activities are the subject of many researches. Their possible use as natural food additives is particularly prominent. This study analyzed the influence of ginger and rosemary oil on the growth of pure bacterial culture using the disk diffusion method. Escherichia coli, Staphylococcus aureus and Salmonella spp. were used as test organisms for antimicrobial susceptibility testing.The results showed that both types of oil inhibit bacterial growth, although inhibition rate varies between different bacterial species. It certainly depends on the type of plant used for oil extraction. Study has shown that ginger and rosemary oil can potentially be used in treating diseases caused by these bacteria.

Sweet corn (Zea mays L. var. saccharata [Sturtev.] L.H. Bailey) is a thermophilic crop that is sensitive to cold stress and thus may be cultivated by raising seedlings. The aim of this work was to determine the impact of transplanting and direct sowing on the yield and earliness of the sweet corn crop. The treatment protocol used had a combination of two different cultivation technologies (transplanting and direct sowing) and two different sowing periods (8 and 15 May during both growing seasons). The results show that the different cultivation technologies both had significant effects on the productive properties and earliness of sweet corn. The transplanting variants had about 34% more plants per hectare compared with the direct sowing yield. The ear length and mass were higher in crops grown using transplanting (22.2 cm and 278.0 g, respectively) than in crops grown using direct sowing (21.2 cm and 270.3 g, respectively). During the research period, a significantly higher ear yield was noted in the transplanted variants (11.7 t ha-1) compared with those of direct sowing (7.6 t ha-1). The transplanting variants had earlier harvests by 18 and 16 d in the first and second sowing periods, respectively, compared with those of direct sowing.
