Soil contamination is one of the most important factors influencing the quality of agricultural products. Usage of heavy farm equipment, the land drainage, application of inadequate agrochemicals, emissions from mining, metallurgical, chemical, coal power plants and transport, all generate a number of undesired substances (nitric and sulfur oxides, PAHs, heavy metals, pesticides), which after deposition in soil may influence crop quality. Thus, the input of these contaminants into the environment should be carefully monitored. This paper presents the data obtained for organ chlorinated pesticides, their residues, PCB and chlorine benzenes in the soil, tomato plants and fruits of agricultural areas. The samples were taken in March 2014 in the Dukagjini Part, in the village near the Peja and we collect 12 samples. The analysis of the organ chlorinated pesticides was performed by gas chromatography technique using an electron capture detector (GC/ECD). Optima-5 (low/mid polarity,) capillary column was used for isolation and determination of organ chlorinated pesticides. Interpretation of data was performed using cluster analyze models. Relatively low concentrations of organ chlorinated pesticides and their metabolites were found in the studied samples. Two were the main groups, DDTs and HCHs. The presence of organ chlorinated pesticides residues is probably resulting from their previous uses for agricultural purposes. PCB 52 was the main congener found in soil samples and hexachlorobenzene was the main compound for chlorinated benzene compounds.

After wheat, maize (Zea mays L.) is the second most important cereal crop in Kosovo and a major component of animal feed. The purpose of this study was to analyse the incidence and identity of the Fusarium species isolated from naturally infected maize kernels in Kosovo in 2009 and 2010, as well as the mycotoxin contamination. The disease incidence of Fusarium ear rot (from 0.7% to 40% diseased ears) on maize in Kosovo is high. The most frequently Fusarium spp. identified on maize kernels were Fusarium subglutinans, F. verticillioides/F. proliferatum and F. graminearum. Maize kernel samples were analysed by LC-MS/MS and found to be contaminated with deoxynivalenol (DON), DON-3-glucoside, 3-acetyl-DON, 15-acetyl-DON, zearalenone, zearalenone-14-sulphate, moniliformin, fumonisin B1 and fumonisin B2. This is the first report on the incidence and identification of Fusarium species isolated from naturally infected maize as well as the mycotoxin contamination in Kosovo.

The main goal of this research has been to investigate the efficiency of chemical preparations and their sustainability of apple cultivars against powdery mildew pathogen (Podosphaeraleucotricha) .Three cultivars of apple (Jonathan, Idared and Vizajkanative cultivars) have been tested in experimental fields (in the municipality of Peja, Kosovo) during the two years of research (2013 -2014) .Fungicides that are used were: Webeton (triadimefon), Rubigan (fenarimol), Karathan EC (dinocap) and Kossan WG (sulfur). During the vegetation has been made eight spraying, three spraying before the blossoming and five spraying after the blossoming, within a period of 10-15 days between spraying and sprinkling. After that, there have been done three evaluations of the disease and the results obtained have been processed according to Mc Kinney index. Through the processed results has been seen that higher efficiency of chemical preparations has been in the and in Rubigan and Karathan combination EC (variant -B1), during the two years of the research. Whereas, regarding the suitability of cultivars to pathogen, cultivar "Vizajka" (native cultivar) showed the highest sustainability against disease pathogen, where, the index in the first and second year of the research has been lower in all variants as well as to control compared to two other cultivars. While, the most sensitive cultivar against powdery mildew pathogen was Jonathan with the higher disease index compared with two other cultivars.
