Date bunch fading disorder (DBFD) has been one of the major issues facing date palm growers in recent decades. This order has caused high and non-compensable losses to date palm product. Despite numerous studies, predominantly focusing on the causes and mitigation methods of this disorder, no precise influencing factors have been established and practices which can completely control it are not...

the fruit of date palm (phoenix dactylifera l.) is an important horticultural product in the middle east and north africa. among more than 400 reported date palm cultivars in iran, around 20 cultivars are more important due to having better eating quality and trading values. in this study, the fruit of nine commercially important date cultivars including ‘barhee’, ‘breim’, ‘deiri’, ‘fersi’, ‘ga...

gasification is a well-known reaction owing to its relevance to generation of sustainable energyfrom biomass and development of porous carbons. the present paper attempts to experimentally investigate the kinetics of palm shell char gasification using carbon dioxide (co2) in a controlled environment using thermo gravimetric analyzer (tga) at temperatures ranging from 800 to1000°c. a relevant ki...

active carbon is char derived from pyrolysis of organic materials. it has a high porosity level and is used to filter fluids. many types of agricultural materials are used to produce active carbon. the trunk of the date palm, with its low density and high porosity, has great potential for producing active carbon. in this research, the bark was pyrolyzed at 450°c for 60 min to produce active car...

dubas bug, ommatissus lybicus de bergevin (hem.: tropiduchidae), is a key pest of date palms in iran.this pest was first reported on date palms in 1966 and has been established throughout the date producing regions in southern iran since. date palm is the only host plant of dubas bug. it attacks almost all date palm varieties, esp. mazafati variety in city of bam, kerman province and other vari...

oligonychus afrasiaticus is a major pest of date palm orchards in iran and middle east countries. effects of amitraz, fenpropathrin, fenpyroximate, fenazaquin, propargite), tetradifon, and hexythiazox were evaluated in southern part of iran. the complete randomized block designed with three replications used on mordarsang, kabkab, barhi, mazafati, and halileh major date varieties cultivated in ...

background: date palm pollen (dpp) and astragalus genus are used in some countries for the treatment of infertility. objective: this study was designed to investigate effects of dpp and astragalus ovinus (a.ovinus) on fertility in healthy adult male rats. materials and methods: thirty-six rats were divided into six groups (n=6) including control and five treatment groups. dpp (120, 240 and 360 ...

Date palm thorn injuries are common in Middle Eastern countries, where there are many date palm plantations. If detected, these injuries can be treated without subsequent complications. In children, however, the diagnosis can very easily be missed. An untreated embedded thorn may cause late complications, including periostitis or osteomyelitis. In this article, the author presents a case of dat...

Development of red date palm weevil Rhynchophorus ferrugineus (Olivier) was evaluated on 4 popular cultivars of date palm, viz., ‘Khalas’, ‘Sukkary’, ‘Khasab’, and ‘Sillaj’ for 2 consecutive generations. The weevils reared on ‘Sukkary’ showed significantly better growth expressed in most parameters such as length, width and weight at larval, pupal and adult stages. Significantly greater numbers...

Waste palm dates were subjected to analysis for composition and enzymatic hydrolysis of their flesh fibers. The fruit contained 32% glucose and 30% fructose, while the water-insoluble fibers of its flesh consisted of 49.9% lignin and 20.9% polysaccharides. Water-insoluble fibers were settled to 55% of its initial volume in 12 h. The presence of skin and flesh colloidal fibers results in high vi...
