Abstract

The degradation trend and descending capacity of Iran’s renge lands due to lack of regular policy and programming in it’s usage, increasing of population, food and protein requirements, are some of problems that turned the ammenment and improvement of rangelands as an essential problem for the users.
Eurotia ceratoides plant, due to bushy from, resistance to drought, proper protein percent, simple propagation and… is one of the native plants of desert rangelands that has special importance in arid and semiarid rangelands these charachteristics caused to wide use of this plant in  rangelands ammendment programs.
 The aim of this research was to determine the optimum time for sowing and the best method for sowing of this species in desert rangelands, to use in rangeland management designs.
This research was conducted in split plots experimental design frame, in the main plots the sowing date was in 4 treatments (5^th of December, 5^th of Junury, 5^th of Februry and 5^th of March) and the secondary plots were included 4 treatments (Heap cropping, Hole cropping, Sowing with disct moldboard, Sowing with plow) with 4 replications in 2 successive years of 1996 and 1997 in plots with 6 * 4 dimensions. The number of established plant per plot was determined and the data analysis was done by SAS program . Results showed that, the best method of sowing in establishment percent of Eurotia were sowing by plow and disc, heap cropping and hole cropping respectirely. The dates of 5^th of December and 5^th of Junury had more establishment percent. The plow and disc methods in 5^th of December had the most establishment percentage.
