Abstract

This research aimed to evaluate the effects of cultivating time (spring and autumn) on some morphological traits of ten genotypes of 5 species of Astragalus including Astragalus brevidens, Astragalus lilacinus, Astragalus cyclophylon, Astragalus subsecondus and Astragalus vegetus in Homand Absard rangeland research station. A completely randomized design was used to cultivate the genotypes in three replications on two lines of two-meter length with a row spacing of 0. 5 m for each genotype and 0. 75 m for different species. forage production, canopy cover percentage, canopy diameter and height, seed yield, and the number of flowering stems of the species were measured. Analysis of variance and Duncanchr('39')s Multiple Range Test were performed for mean comparisons. According to the results of the third year of cultivation, the two treatment groups (spring and autumn) showed significant differences in terms of the measured traits and genotypes. Although autumn cultivation caused an increase in forage production, canopy cover percentage, height and the number of flowering stems, their seed yield did not vary significantly. A. vegetus (Gharebagh and Kurdistan) and A. brevidens (Tandure and Torogh) genotypes had the maximum performance for all the measured traits. A. vegetus (Kurdistan) genotypes with 2740 kg/ha forage production and producing appropriate canopy cover had the best performances compared to the other species. Results showed that autumn is the best time to cultivate these herbaceous species from the Astragalus genus. The findings of this study are applicable for restoring degraded semi-arid rangelands with annual precipitating more than 300 mm.
