in order to  study the effect of beet mosaic virus on sugarbeet seed yield, an isolate of beet mosaic virus was collected from sugarbeet fields in karaj and biologically was purified by inoculation on chenopodium amaranticolor and propagated on beta vulgaris cv. cicla under greenhouse conditions. the infected sap was inoculated on leaves of  sugar beet  7233 variety at  two stages, after and be...

to evaluate the effects of some phosphorus solubilizing bacteria strains on yield and agronomic traits in local bean (phaseolus vulgaris l.) of guilan, different phosphate fertilizer rates were tested during 2014 growing season. this research was carried out in experimental field of agricultural and natural resource research center of guilan province as split plot arrangement based on randomize...

The seed-borne mycoflora of sorghum and foxtail millet collected from different growing areas in South Korea were isolated and taxonomically identified using dry inspection, standard blotter and the agar plate method. We investigated the in vitro and in vivo germination rates of disinfected and non-disinfected seeds of sorghum and foxtail millet using sterilized and unsterilized soil. The perce...

Entomopathogenic fungi (EPF) of different genera are known to have the potential engage in fungus-plant interactions as fungal endophytes. This hidden endophytic interaction offers several advantages host plants, such insect pest management. Hence, this study aimed explore and virulence EPF collections after artificial inoculation. A total 27 isolates from Beauveria Metarhizium were screened fo...

Aflatoxin assays and moisture determinations were made on locks from bolls inoculated with Aspergillus flavus 30-32 days from flower and harvested after additional periods of 5, 7, 9, 11, 13 and 15 days. Inoculated locks were always tight but had moisture contents comparable to those in noninoculated locks on the same bolls. Lowest toxin concentrations were in seeds from bolls still green at ha...

Field experiment was conducted at the Instructional Farm of Krishi Vigyan Kendra, Chhatarpur during two consecutive kharif 2017-18 and 2018-19 to evaluate effect different biofertilizers along with 75 % recommended dose fertilizers on growth, yield, nutrient uptake, use efficiency B:C ratio greengram (Vigna radiata L.). Results revealed that application NPK seed treatment Rhizobium @ 10 g/kg so...

Pistachio fruit components, including hulls (mesocarps and epicarps), seed coats (testas), and kernels (seeds), all contribute to variable aflatoxin content in pistachios. Fresh pistachio kernels were individually inoculated with Aspergillus flavus and incubated 7 or 10 days. Hulled, shelled kernels were either left intact or wounded prior to inoculation. Wounded kernels, with or without the se...

Variations in moisture and substrate in preharvest corn kernels and cottonseed were linked with the ability of Aspergillus parasiticus to infect the seed and produce aflatoxin. Osmotic pressures and moisture content (MC) levels of developing starch-rich corn kernels and lipid-rich cottonseed were determined. For in vivo studies, corn kernels and cottonseed were inoculated with A. parasiticus co...

Leguminous crops, possessing root nodules, fix and utilize atmospheric nitrogen. They are thus not dependent on industrially fixed nitrogen but add up to 30 kg of nitrogen / hectare to the soil and improve its fertility. Access to mineral nitrogen often limits plant growth, and so symbiotic relationships have evolved between plants and a variety of nitrogen-fixing organisms. These associations ...
