A laboratory experiment was conducted to test the effects of variety and fungicides on percentage germination and seedling vigor of rice seeds. The experiment was conducted at Crop Science and Horticulture Laboratory, Nnamdi Azikiwe University, Awka, Anambra State. The experiment was a 2 x 4 factorial laid out in a Completely Randomized Design (CRD) and replicated three times. The result showed that there was significant effect of fungicide on percentage germination of rice seeds. There was no significant effect of variety on percentage germination of rice seeds where the highest percentage germination of 86.7% was obtained in Faro 44, which was statistically same with 69.0% obtained in Faro 52. The result also showed that the different fungicides had significant effect on germination of rice seeds where the crude extract of Aidan fruit pulp gave the highest (91.3%) germination. The same was also obtained in crude extract of Aidan fruit seed which is statistically different from 88.7% seed germination of rice obtained in Mancozeb and 40.0% obtained in Dressforce (D). It was also observed that the least percentage germination (40.0) was obtained in rice seed dressed with Dressforce (D). Both the plant extract and synthetic fungicide where effective in protecting the price seeds, though the plant extract had higher germination index than synthetic fungicide. Various fungicide had significant effect on vigor index of rice seeds where Mancozeb (M) had the highest seedling vigor index (34.0) followed by 19.2 obtained in rice seeds dressed with plant extract from seed of Aidan fruit while the least (9.2) obtained in rice seeds dressed with Dressforce (D). Generally, rice seeds dressed with Mancozeb gave highest seedling vigor index than the other fungicides. From this experiment it was observed that Dressforce had low germination because of the phytotoxic effect of the chemical on the rice seeds. There was no significant effect of the different fungicides used on percentage infection of rice seeds though rice seeds dressed with seed extract of Aidan fruit gave the highest percentage infection (6.67%) which was followed by pulp extract (4.0%) while the Dressforce and Mancozeb gave no infection. It is therefore recommended that for higher percent germination of rice seeds fungicides from crude extracts of Aiden fruit should be used but the synthetic fungicides-Dressforce and Mancozeb should be used for reduced fungi infection.
