Abstract
Nowadays; planting of Atri;lex species are used, in range rehabilitation. Soil erosion control and wildlife programs. Optimum density, and periods of prunning of Atriplex lentiformis on quantity of forage production are important. The Atriplex lentiformis was planted in a split-split plot design with 3 replications and 45 treatments in Dadin of Kazeroon in 1993 and investigated for 10 years. The main treatment was planting distance at levels. Sub-treatment was prunning period and the sub-sub-treatment was cutting height. Canopy coverage diameter, height, forage production, and percentage of survival of the plant were measured in different years throughout of the study. The nutritional value of the forage was measured in the last year. The data were analysized by EXCEL, SPSS, and SAS softwares. The results showed that the highest production attained from treatments of 2*2 m planting space, 40 cm height, and once per year cutting, and the least one, resulted of the treatment of 4*4m planting space, zero cm and once per three years cutting. Control and zero height cuttings showed a significant difference (P<0.05) with the other treatments in forage production. The 20, 40, and 60 cm cutting heights showed no significant difference (P>0.05). Zero and 20 cm cutting height showed a significant differece (P>0.05). Zero and 20 cm cutting height showed a significant difference with other treatments in percentage of survival (P<0.05).
