Resumen

SAJJAD HAIDER, Muhammad et al. Effect of Grazing Systems on Range Condition in Pabbi Hills Reserve Forest, Kharian, Punjab, Pakistan. Chilean J. Agric. Res. [online]. 2011, vol.71, n.4, pp. 560-565. ISSN 0718-5839.  http://dx.doi.org/10.4067/S0718-58392011000400010.

Grazing management of rangeland systems has not been well researched in Pakistan; grazing system the most sustainable is not known. In order to evaluate various grazing systems, a study was performed at Pabbi Hills Reserve Forest, Kharian, Punjab. Four simulated grazing treatments, viz. ungrazed control, continuous grazing, seasonal deferred grazing, and rotational deferred grazing, were tested in a randomized complete block design with four replicates. Response variables included species composition, fresh herbage yield, dry herbage yield of grasses and forbs, basal cover, and ground cover. Of the three grazing systems, the six-month seasonal deferred grazing system resulted in a marked increase in basal cover, but had no changes in relative species composition. A significant increase in grass cover and herbage production were also observed in this grazing system, suggesting that the 6-mo seasonal deferred grazing system is the most sustainable rangeland system.

Palabras clave : Sustainable rangeland system; basal cover; species composition; herbage production; ground cover; six-month seasonal deferred grazing system.
