EFFECTS OF CERTIFICATION OF WHEAT FIELDS AND SEED YIELD

The research purpose was application of the standards for seed production schemes, namely the evaluation of the effects of field certification, based on the Kosovo Seed Law and the OECD Guidelines. The object of the evaluation were the wheat fields for seed production, yield and quality of seed produced with dedication Kosovo market during the years 2014 (Y1) and 2015 (Y2). The certified seed C1, is sown to reproduce C2. The origin of cultivars was from different countries, but registered on the Official Seed List within MAFRD. The experimental design was a random complete block design (RCBD) with quadrants of 20 m2, with three replications. For the data analysis were used ANOVA, according to the program MINITAB-16©. The application of the certification standards of the wheat fields resulted in certified or rejected fields, in particular in the case of presence of wild oats. The mean results for the parameters were: seed yield (SY=494.81g m2), spike weight (SW=1.59g spike-1), grain weight per spike (GWS=1.13g spike-1), harvest index (HI=0.43) and wild oat presence (WO = 8 to 33 plants ha-1). Researched parameters shown significant differences for the level of LSDp=0.05 and LSDp=0.01. Application of the certification standards for wheat fields ensures the identity of the cultivar, the genetic and physical purity of the seed, without the weed seeds, and with the defined phytosanitary status.
