This research was carried out in laboratories of Field Crops Department of Erciyes University Agricultural Faculty between the dates September-October 2010. Factorial experimental design with randomized blocks was used for experiments. Seeds from previous research carried out in Agricultural Research and Extension Center of Ataturk University Agricultural Faculty during the cropping seasons of 2006-07, 2007-08 and 2008-09 under dry farming conditions were used as the material of present research. In previous study, two weed cultivars (Kırik, Doğu-88), three weed control practices (475 seeds/m2, 475 seeds/m2 + hand weeding (HW), 625 seeds/m2) and seven fertilizer sources [Control, standard inorganic (NP), Bio Organic (Bio), Bio Organic SR (Bio SR), Leonardite, Organic Fertilizer (OF), Cattle Manure (CM)] were included. Biological characteristics of seeds (germination rates, germination powers, emergence rates and emergence powers) were investigated in current study. As the average of treatments, germination rate was found to be as 87.8%, germination power as 93.2%, emergence rate as 68% and emergence power as 92.1%. Cropping seasons significantly affected the biological characteristics and 2006-07 cropping season had lower biological values than the others. Difference between cultivars with regard to biological characteristics was found to be significant. Weed control practices significantly affected germination power, emergence rate and emergence power values. Fertilizer sources had also significant impacts on biological characteristics. With regard to fertilizers, the lowest values were obtained from control treatment and the highest values from NP, OF and CM treatments.
