Abstract

     This experiment was carried out during the 2019/2020, 2020/2021 seasons at the Khormaksar-Aden Food Research Centre Laboratory to test the bacterial content in two varieties of seeds of Sorghum bicolor by using the powders of Azadiracta  indica leaves, Capsicum annum result, Acacia tortilis ash and Mineral rocks Which was used in the average (25gm/kg seeds) and different storing tools, mental, plastics, jiut. The laboratory tests were done during 3, 6,9,12 months for two planting seasons and the results were analysed by using the factorial experiment conducted in four times for each operation. For decreasing the bacteriara Xanthomonas sp in the two varieties Sanisalah and Bini ,Azadirachta indica was the best (677,630 cell/gmseeds) respectively ,Capsicum annum (1830,1770 cell/gm seeds) respectively, Acacia tortilis ash (2206,2122.5 cell/gm seeds) respectively, then Volcanic rocks (3354,3270cell/gm seeds) respectively as compared to the Control (4579.5,4510cell/gmseeds) respectively.
For reducing the number of bacteria cells that attack the seeds stored for two season, the best storing containers were metal(615,540 cell/gm seeds) respectively, plastic(1087,1015 cell/gm seeds) respectively ,polyethylene(2618,2535 cell/gm seeds) respectively, then Jute (5797,5700 cell/gm seeds)respectively.
According to this study, the bacterial content of seeds increased during the storing period.
