Investigation of Forage Cactus Plantation (Opuntia ficus indica L.) in Reviving and Repairing Destroyed Tropical Rangelands (Case Study: Qasrshirin Rangelands of Kermanshah Province)

Therefore, in order to evaluate the cultivability of forage cactus (Opuntia ficus indica L.) in the Naft shahr of Qesir shirin city, Kermanshah province has been considered. Different treatments without irrigation, 1, 15, 30 days, once irrigation in three repetitions for three years were performed based on a completely randomized block design. Cultivation of cactus plant in the first half of November and irrigation began on the first of June. The means of the results were compared using Duncan's multiple range test in SPSS software.The results of analysis of variance showed that the effect of irrigation cycle and the interaction effect of irrigation cycle at the time of measurement on the number of pads and plant height had a significant effect at the statistical level of 0.01. Survival of 75, 57, 43 and 38% of plants was obtained with 15-day irrigation cycle, 30-day treatment, one-time irrigation and no irrigation treatment, respectively. The results of this study show that planting cactus in areas with arid desert climate such as Qesir shirin and Somar in Kermanshah province is recommended due to its high adaptability. Dry forage production Cactus forage can be effective for livestock development in these and similar areas. Also, due to the role of cactus in soil conservation, it is possible to prevent the occurrence of dust, desertification, pasture destruction and soil erosion in the region by developing crops. Also,
