The aim of this study was to determine the variability in herbage yield and quality of rangelands depending on the application of organo mineral and composite fertilizers. The experiments have been carried out in the years 2010 and 2011 in Gerlengeç Village of Biga District situated in Canakkale Province, Turkey. The research was established according to the randomized complete block design by using 4 replications. Organo mineral (5–10–0) and composite (20–20–0) fertilizers were used as fertilizers, whereas 0, 50 and 100 kg N/ha as doses. Hay crude protein, crude ash, NDF, ADF and ADL along with the yield of dry hay ratios have been investigated in this research. The ratio of hay crude protein, crude ash as well as the yield of dry hay of rangelands have been increased depending on fertilizer application, but this increase was significantly important upto 50 kg N/ha. On the other hand, the ratios of NDF, ADF and ADL have been decreased. In addition, the ratio of NDF, ADF and ADL increased, while the crude protein and ash amounts of hay decreased depending on plant development. As a result, it is recommended to apply 50 kg N/ha for both fertilizers in terms of yield and quality of hay in rangelands.
