ABSTRACT

Context: This study was conducted at the Nkoemvone Agricultural Research Station in southern Cameroon, focusing on maize cultivation from September to November 2022. The objective of this study was to assess the effectiveness of rabbit urine in comparison to a standard chemical pesticide on maize yield. Objective: The aim was to provide guidance to farmers on the use of biopesticides instead of chemical pesticides to ensure food security. Objective: The specific objectives of this study were to determine the appropriate dosage of rabbit urine, reduce pest attacks, and quantify the resulting maize yield. Method: The experimental area covered a total of 750 m², with individual plot sizes of 250 m². Each plot was further divided into four units, representing different treatments. The treatments were randomly assigned to the three primary plots as follows: T0 = absolute untreated control, T1 = urine concentration of 1.5 liters in 10 liters of water, T2 = urine concentration of 2.5 liters in 10 liters of water, and T3 = application of GREMEC 50 WG at a rate of 10g per 16 liters of water using a backpack sprayer. The evaluation of these treatments was based on four parameters: the number of diseased plants, the number of pest-infested plants, and the number and weight of maize ears. The data analysis employed ANOVA to conduct the statistical analyses. The experimental design employed a completely randomized design to assess the effect of rabbit urine. Results: The results showed no significant differences among the treatments regarding the number of diseased plants. However, there was a significant effect observed for T0 (79) and T3 (34) compared to T1 (52) and T2 (48) in terms of the number of pest-infested plants on average. Similarly, there was a significant difference in yield, particularly the number of maize ears, among the treatments: T0 (101), T1 (202), T2 (178), and T3 (186) ears. No treatment exhibited a significant effect on the weight of maize ears. Conclusion: These findings suggest that rabbit urine could serve as a viable alternative to chemical pesticides. However, it is crucial to pay attention to the dosage used, as excessively high doses may harm the plants, while excessively low doses may not yield the desired effects.
