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...

date palm tree reaction to fertilizer is very slow, due to the trunk nutrients. this fact leads to farmer unwillingness to feed the trees. however, balance fertilizing improves vegetative growth and reduce the period for flowering. this study aimed to assess the effects of manure, chemical and organic sulfur on vegetative characteristics of ‘piarom’ date palm offshoot in a randomized complete b...

The objective of the study was to analyze chemical structure of date palm (Phoenix dactylifera L.) by employing ultimate, proximate and thermo-gravimetric techniques. Samples from different anatomical parts of date palm, namely trunk, frond base, frond midrib, leaflets, coir, fruit stem, date stone, and fruit empty bunches were considered for the experiments. Based on the findings in this work ...

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...

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...

Phyllotaxis is the study of the morphological order of plants. Remarkably, in spite of the overwhelming diversity of plant morphology, there are common patterns that link a wide variety of species. The date palm, having a phyllotactic order, possesses a simple, repetitive model. Only a small number of parameters are needed to represent the phyllotactic order of the date palm. This a priori know...

In this study, the physical properties of briquettes produced from two different biomass feedstocks (sawdust and date palm trunk) and different plastic wastes, without using any external binding agent, were investigated. The biomass feedstocks were blended with different ratios of two waste from electrical and electronic equipment (WEEE) plastics (halogen-free wire and printed circuit boards (P...
