Six different formulations were prepared, using different carrier materials namely; peat moss, mixture of peat moss plus vermiculite 1:2 (w/w), wheat bran, rice husk, clay and sodium alginate. Each carrier material was packed using polyethylene pages, and then divided into three groups. The first group was sterilized by autoclaving at 121˚C for 20 min, the second one was sterilized by gamma irradiation at a dose rate of 4.0 kGy for 1 hour. However the third group was left without sterilization. Half of the inoculated polyethylene bags, containing the tested formulations either sterilized...

This investigation was designed to determine the effect of organic fertilizer, soil solarization and Bio-fertilization with vesicular arbuscular mycorrhizae (VAM) on plant growth, yield and quality of pepper fruit and to control soil-borne fungi and weed seed. Solarization combined with chicken manure increased maximum soil surface temperature 3.0 C than solarized treatment alone as average of both seasons. Solarization 100% reduced the emergence of weeds, by killing or inhibiting the germination from the upper 15 cm. Solarization treatment significantly increased number of infected roots by...
