Abstract

Variation for forage production was surveyed between ANNUAL MEDICS under various periods of irrigation. The research was carried out in a factorial experiment based on a completely randomized design with 3 replications in Zalleh Research Station, Sanandaj, Iran, 1995. Studied factors were humid with 4 levels (irrigation intervals including 5,4,3 and 2 days) and medic species with 6 levels (1-Medicago truncatula, 2- M. scutellata, 3- M .rigidula, 4- M. littoralis , 5- M. rogosa paragosa and 6- M .orbicularis). Results showed that average shoot (SW) and root (RW) shoot and root dry weight of aerial part (SW) and root part (RW) of plant were 5 and 4.7 g respectively and SW/RW ratio was about 1. Based on the analysis of covariance (number of plant in vase as covariate), humidity levels showed significant differences P<0.01 for SW and RW and the watering interval of 2 days caused the highest weight and watering interval of 5 days caused the lowest weight of SW and RW. Differences among species for SW and RW was significant P<0.01. Mean comparison (Duncans multiple range test at p£0.01) showed that M.tr., M.Sc. and M.ri. In addition for SW and RW were higher than other species. Also, interaction of humid – species for SW and RW was significant (p£0.01). This means that different species of medics showed different reaction to humid changes. M.tr. and M.ri. As 2 resistant species in all humid levels showed stability in SW and RW. M.sc. has showed high SW and RW only in high humid condition. RW showed and significant (p£0.01) positive correlation (r=0.91) with SW and so regression coefficient (b) RW on SW was significant (p£0.01) and determination coefficient (R²=%98) was very high.
