Therefore, this research was carried out to evaluate the effect of kraft paper, black, white, and blue cloth, green greenhouse netting, straw bag, and without bag (control) at the khalal stage on the ripening rate and sunburn incidence of cv. Medjool using randomized complete block design with eight replication in in Umm al Tameir research station, date palm and tropical fruits research, Ahvaz, in 2020 and 2021. The bags' ends were open and remained on the trees until harvest. The results showed that the bunch weight, the kimiri, khalal and date fruits proportions were affected by year.
