The screening of entomopathogenic fungi, 7 isolates of Metarhizium spp., 12 isolates of Beauveria spp., and 1 isolate of Hirsutella citriformis against fruit fly was performed in Lampang Agricultural Research and Training Centre, Lampang, Thailand. The efficacy test was done by spraying suspension of 10 spores per ml of fungus on Bactrocera dorsalis in completely randomized design experiments. ...

ruminal bacteria and protozoa provide excellent organic phosphorus (p) sources for the host animal. this experiment was conducted to compare the bioavailability of bacterial and protozoal p in comparison with that of dicalcium phosphate (dcp) as a reference phosphorus source. bacteria and protozoa were isolated from the rumen contents of dairy cows and the chick-model was used to determine the ...

to protect and multiply important and rare plant resources, in vitro culture serves as a more efficient alternative to traditional propagation approaches. levisticum officinale koch. a member of apiaceae is an important, endangered and neglected species in iran, which has been shown to have diuretic, spasmolytic and carminative effects. in order to supply enough plant materials for micro-propag...

phytoextraction is a remediation technology that uses plants to remove heavy metals from soil. the success of a phytoextraction process depends on adequate plant yield (aerial parts) and high metal concentrations in plant shoots. a pot experiment was conducted to investigate the combination effects of plants [sunflower (helianthus annuus) and canola (brassica napus)] with soil treatments (manur...

one of the most important adverse environmental effects of herbicide application in production systems is possible damage to non-target plants, such as crops that are grown in rotation. nicosufuron+rimsulfuron (ultima) is a sulfonylurea herbicide that recently registered for use in maize fields in iran. its residues may be present more than a season in certain conditions. to measure nicosufuron...

apricot is climacteric and its ripening process is regulated by ethylene, therefore, inhibiting ethylene biosynthesis or action should slow the ripening process. this study was conducted to decrease materials losses and increase storage life of fruit by proper packaging. different packaging (polyethylene film, polyethylene film with ethylene absorbent, shrink pack and control) were used. after ...

the aim of this research was to improve postharvest quality and vase life of tuberose cut flowers. treatments in this experiment included: distilled water, 3% ethanol and 5% sucrose as control, thyme oil in 3 levels (50, 75 and 100 mg/l), accel in 3 level (25, 50 and 75 mg/l) and for some of flowers pulsing with 5% sucrose in first 24 hours then puting cut flowers treated with sucrose in thyme ...

this study investigates monthly and seasonal variations of carbon emission from the soil at different grazing intensities. three areas of exclosure, low and high grazing intensities were selected in ghoosheh region of semnan province. carbon emission was measured monthly, in each treatment applying alkali traps (csc) during a year. emission and grazing data were analyzed, using a factorial expe...
