in this study, penicillium digitatum, the causes of green mould disease of orange fruits, were isolated from infected fruit in bam city. antifungal activity of three different plant essential oils eucalyptus camaldulensis, zataria multiflora, myrtus communis at 50, 100, 150 and 200 ppm concentration, have been evaluated. mic (minimum inhibitory concentration) and growth inhibition zone diameter...

In order to study the contamination of Aspergillus flavus and aflatoxin production in pistachio cultivars in the Semnan province, eight cultivars of pistachio were collected from major pistachio growing areas. Using the serial dilution method, ground pistachio kernels were inoculated on plates containing AFPA medium and incubated at 28° C. This experiment was performed using three replications ...

the effect of arbuscular mycorrhizal fungi and plant growth promoting rhizobacteria, with the ability to produce acc deaminase enzyme, on water relationships and agronomic indices of sunflower (helianthus annuus l.) cultivars was investigated. the soil used was of an ec equal to 7.6 ds m-1. a greenhouse factorial experiment on the basis of a completely randomized block design with three levels ...

biosecurity in the production of broiler chickens is very important but it is hard or even impossible to maintain; hence, promotion of immune responses could control diseases in chickens. at present study, the effect of six levels of oil-extracted propolis (0, 50, 100, 150, 200 and 250 mg/kg ration) on immune system against newcastle virus was studied using a completely randomized design with 3...

the present study was conducted to evaluate the effects of these two factors as well as their interaction on seed germination of eucalyptus (e. camaldulensis). a factorial experiment based on a completely randomized design with three replications was used. five salinity levels including 0, 50, 100, 150, 200 mm sodium chloride were tested on seed collected at top, middle and bottom of the tree. ...

peanuts, an oilseed crop, contain about 46% oil. the peanut shell can be used as fuel or pallets and its dry matter as feedstuff. the whole pods consist of 1-6 kernels. shelling is done at harvest time when the pod moisture content is 5-10%. in this research, a peanut sheller was designed and developed to separate the shell from the pod. the sheller included a hopper, sheller cylinder, concave,...

Two nonparametric tests are proposed in testing for k nondecreasing treatment effects under a mixed design consisting of a completely randomized portion and a randomized block portion. The randomized block portion may contain missing observations for some of the treatments within a block. A simulation study is conducted to estimate the powers of the two tests for 3, 4, and 5 treatments under a ...

This experiment was carried out to study the effect of humic acid and growth promoting bacteria on uptake of cadmium heavy metal by annual alfalfa (Medicago scutellata L.). The experiment was arranged in pot experiment conditions in Isfahan, Iran in 2011. A factorial design was used based on completely randomized block design with four replications. Experimental treatments were humic acid and g...

Allelopathy offers potential for weed control through the production and release of allelochemicals from leaves, flowers, seeds, stems and roots.  In this research, allelopathy potentials of ethanolic and aqueous extracts of Vinca rosea L. leaves were evaluated. Three extract concentrations, including 2.5, 5 and 10% (w/v) of both aqueous and ethanolic were prepared from a 10% w/v stock solution...
