Abstract

Determination of FORAGE QUALITY of available species is one of the fundamental factors for the management rangelands. NDF, ADF, CF, Cp and digestibility are some of the important factors in evaluation of FORAGE QUALITY. The present research was conducted in JAVAHER DEH OF RAMSAR range having an elevation of 2500 m above sea level and annual precipitation of 700 mm. During the study, samples were collected from TRIFOLIUM PRETENSE and CORONILLA VARIA species with eight replication from exclosured area. NDF, ADF, CF, Cp and total energy were then measured for the analysis of flowering and seeding stages. Soil samples of root zone were also collected for EC, pH, K, P and N. ANOVA and regression test were applied using SPSS to investigate the FORAGE QUALITY changes during phonological stages and the relationship between soil characteristics and phonological stages with FORAGE QUALITY indices. The results showed that FORAGE QUALITY of both species was higher in flowering stage than that of seeding stage. Which is because of high value of CP and also low degree of ADF, NDF and CF. FORAGE QUALITY changes of T. pretense in phonological stages was more than C. varia species. However, the FORAGE QUALITY of T. pratense in flowering stage was higher than of C. varia while it is reverse in seeding stage. In present study significant correlation was no found between FORAGE QUALITY and soil characteristics except in case of the relationship between soil nitrogen, crude protein and total energy of C. varia.
