Abstract

Laboratory experiments and tests were conducted to study the effect of treating seed
of peanut varieties; (Giza 6 and Giza 5) with moringa leaf extract and vitavax fungicide before storage
in different packing materials (cloth, polypropylene and aluminum foil bags) for zero time (control), 6,
12 and 18 months from seed treatments, on seed germination (%), seed vigor, seedling vigor traits and
fungi infection. The main results could be summarized as follows: there were significant differences
between peanut varietie’s (Giza 6 and Giza 5) seeds in seed germination (%), seed vigor, seedling
vigor and fungi infection (%) where, Giza 6 variety surpassed Giza 5 variety after the different storage
periods. Seed treatments significantly affected seed quality traits as measured by germination (%),
good seedlings, tetrazolium potential, electrical conductivity, germination index, oil (%) and fungi
infection (%). Fungicide vitavax seed treatment protect seed quality and alleviated fungi infection (%)
after the different storage periods followed by moringa leaf extract comparing with untreated seeds.
Type of seed packing materials, significantly affected seed germination, seed vigor, seedling vigor and
fungi infection (%) where, packed seed in polypropylene surpassed aluminum and cloth bags. From
the previous results, it could be concluded that treating seeds of peanut Giza 6 variety before storage
with vitavax fungicide and storage in polypropylene bags gave high seed quality and alleviated fungi
infection during storage periods.
