macro and micromorphological investigations were conducted on selected xerepts soils from southern iran to identify changes in soil characteristics with time. soil samples from similar pedons of four irrigated orchards ranging in age from 20 to 100 years were studied and compared with soil samples of a pedon of non-irrigated land. in addition to routine analyses, undisturbed blocks of soils...

date palm spider mite is one of the major pests of date palm in khuzestan.this pest damages fruits in orchards. in the present study responses of 30 native date palm cultivars of khuzestan were evaluated by assessment of pest infestation severity and fruit damage characteristics. based on the responses, cultivars were clustered into four groups as very highly infested cultivars including liloei...

date bunch fading (dbf) is a serious disease of date palm (phoenix dactelifera l.) in iran. fusarium proliferatum was isolated from the xylem of fruit bunch samples sent from kerman and fars provinces groves to the laboratory. koch’s postulates were completed in the greenhouse by crown injection and root inoculations. shriveling of the fruits was induced by peduncle inoculations. symptoms on th...

the effects of ensiling alhagi with waste date palm on rumen parameters and microbial protein synthesis in kermani sheep were investigated. 100 kg alhagi with 20 kg waste date palm were mixed and ensiled for 45 d. the experimental diets containing 0, 7, 14 and 21% alhagi with waste date palm silage. four male kermani rams were used in change over design with four 21-days period. ensiling alhagi...

During the summer, evaporative demand at midday often exceeds the transport capacity of most desert plants. However, date palms maintain their ecological dominance with sustained and uniquely high rates of transpiration. This high rate of flow cannot be attributed to soil water supply alone. In order to quantify intra-plant water allocation in irrigated date palms, three water-sensing technique...

life table of almond moth, cadra cautella walker was studied on four main dry and semi-dry date palm varieties (deyri, zahedi, piarom, and rabbi) of iran under laboratory conditions. data were analyzed based on the age-stage, two-sex life table theory. duration of total preadult stages was 42.54, 45.79, 51.48 and 50.41 days on deyri, zahedi, piarom, and rabbi, respectively. the highest fecundit...
