چکیده مقاله :
Grazing management plays an important role in the continuous and economicutilization of pastures. Proper grazing management is a main factor for the accumulation ofplant litter which reduces soil erosion and increase the soil permeability to keep moremoisture in the soil. In current study, the effect of three different grazing intensities (low,moderate and high) along with the grazing gradient on the forage production rate and plantlitter percentage was investigated on Nodooshan steppe pastures of Yazd, Iran. A randomizedcomplete block with three replications was used to compare three grazing methods. Data forforage production and litter percent were collected from a 2m2 quadrate in each plot. Theresults showed significant differences among grazing systems for both traits (P<0.05). Theresults showed that low grazing had the highest forage production. The regression equationbetween forage production and litter percentage were logarithmic in both moderate and highgrazing intensities. For low grazing intensity, the relationships between two traits showedquadratic egression and therefore, it was concluded that moderate grazing intensity was thebest in terms of both forge and litter production.
