The goal of this study was to determine how Azadirachta indica fruit extract affected seed-borne fungus and seed performance in various rice cultivars.
The antifungal impact of neem fruits grown in the Chadian village of Pala was evaluated on rice seeds. In Bongor, Chad, samples of eight rice cultivars (TOX, CH3, CH8, WITA9 D6, D4, D3, and D1) were collected to evaluate their efficacy against aqueous neem fruit extract.
From June to October 2018, this study was conducted at the Research Unit of Phytopathology and Agricultural Zoology at the University of Dschang/Faculty Cameroon's of Agronomy and Agricultural Sciences.
Rice seeds were dipped in Azadirachta indica extract at T25 (25 mg/ml), T50 (50 mg/ml), and T75 (75 mg/ml) concentrations for 1 hour before being incubated in petri dishes with blotting paper. Negative and positive controls were distilled water (T0) and mancozeb 80 WP (TMn1 mg/ml), respectively.
The germination rate of rice seedlings treated with Azadirachta indica extract was much higher (97.14 percent) than the rate of negative controls (82.53 percent ). The infection rate of rice seedlings, the number of rotten seeds, and the number of aberrant seedlings were all considerably reduced (P =.05) in Azadirachta indica extract treatments compared to the negative control (T0).
Conclusions: The fruit extract of the neem tree (Azadirachta indica) contains bio-fungicidal properties and acts as a bio-stimulator for rice seed germination. This Azadirachta indica fruit extract can be used to boost rice production.
