Influence of Different Dosages of Costus Afer Fermented Extract on Rice Growth

Peat soils are a valuable agroecosystem because of their rarity in Africa (2) and greater heights were noted for T1, contrasting with a relatively lower weed biomass for the higher doses (T4 and T5), with a significant effect (P<0.05) at different physiological stage of the rice. No significant difference was observed between yields, although T5 (7.58 t/ha) outperformed the control (T0) by 49%. However, a dose of 649 l.ha-1 is required for better rice yields.
