Antimicrobial activity and chemical composition of the essential oil of Juniperus communis (L.), originated from east part of Kosova, was investigated. The essential oil from berries of J. communis (L.), obtained by hydro-distillation was analyzed by GC and GC-MS. Antimicrobial properties of the essential oil of J. communis (L.) are investigated and results are submitted for their activities against Staphylococcus aureus, Escherichia coli, Hafnia alvei and Pseudomonas aeruginosa. Applying the agar disc diffusion technique, we measured diameters of the inhibition zone around discs, which are previously wetted with DMF solution of the essential oil with three different concentrations, 1, 3 and 5 mg mL −1 . Analysis of the oil resulted in the identification of 41 peaks, representing 96% of the oil. Berry essential oil composed mainly of monoterpenoids which amounted to 83%, of which 69.4% was monoterpene hydrocarbons. The main monoterpene hydrocarbons were α-pinene (36.2%) and β-myrcene (21.1%). The sesquiterpene accounted for about 13.4% of the total oil composition. Germacrene D (2.2%), α-cadinol (1.6%), α-humulene (1.5%), spathulenol (1.4%), epi-α-bisabolol (1.3%) and germacrene B (1.1%) were the main constituents of the sesquiterpenes. The inhibition zone depends from concentrations and also from sort of bacteria. The inhibition zones differ from 0-39 mm. The present work presents the chemical composition of the hydrodistilled oil of J. communis (L.) from East part of Kosova and the results are compared to those reported in the literature. This study demonstrates the occurrence of α-pinene chemotype of J. communis (L.) from east part of Kosova. The essential oil of J. communis (L.) growing wild in Kosova, showed moderate to high activities against Staphylococcus aureus, Escherichia coli, Hafnia alvei. Pseudomonas aeruginosa is resistant to the essential oil of J. communis (L.) growing wild in east part of Kosova.

Kosovo is the one of the important diversity centers for Cucurbita pepo because of their adaptation to diverse agro ecological conditions as a result of natural and also farmer's selection. In Kosovo, in most cases C. pepo is grown both in maize fields and vegetable gardens as well as in other more intensive systems. Our expedition have identified different location in the part of Kosovo where were collected a samples at altitudes from 545 till 748 MASL. Kjeldahl method we have used to determine Protein content (PC). Lipids were determined by extraction using Soxhlet apparatus and diethyl ether was used as extraction solvent. The aim of the present investigation was carried out to study morphological diversity, protein and lipids content. Pumpkin populations show great diversity in morphological characteristics, particularly fruit weight (FW), fruit shape (FSH). All populations for FW were on higher genetic variability + 2556.9 g or 97.71%. The collection showed appreciable phenotypic variation in fruit shape (FSH). The greater part of variance was accounted for protein content (PC) and lipids content (LC). The estimation overall value µ in seed for PC and LC were 14.59%, and 32.99% respectively. This evaluation of traits variability can assist breeders to identify populations with desirable characteristics for inclusion in variety breeding programs.

Problem statement: We have analyzed the chemical nature of essential oil of Tanacetum parthenium (L.) from East part of Kosova. Approach: The essential oil from aerial part of Tanacetum parthenium (L.), obtained by hidro-distillation was analyzed by GC and GC-MS. Results: Out of 25 peaks, 22 components, which constitute 88%, were identified in oil. The main compounds of Tanacetum parthenium (L.) from east region of Kosova, were camphor (63%) and camphene (9.6%). This study demonstrates the occurrence of camphor/camphene chemotype of Tanacetum parthenium (L.) from east part of Kosova. The present study showed the chemical composition of the hydro-distilled oil of Tanacetum parthenium (L.) from East part of Kosova and the results are compared to those reported in the literature. Conclusion: After comparison of our date with those reported in literature we can conclude that genetic and environmental factors play role in determining the composition of essential oil of Tanacetum parthenium (L.).

The aim of this study was to assess the presence of metals in three regions of Kosovo using chicken (Gallus gallus domesticus) breast feathers collected from the industrial regions of Mitrovica and Obiliq and the non-industrial region of Dragash. This study was carried out from September to November 2016, and feathers were collected from 90 individual domestic chickens housed as free range. The concentrations of metals in the chicken feathers were determined with atomic absorption spectrometry (AAS). The range of average measured concentrations of metals (µg g -1 ) in examined regions were:
