ABSTRACT
Background: Maize is one of the graminaceae that are more cultivated in the world. It is a basic food culture most largely practiced in sub-Saharan Africa. In Cameroon, maize is the principal source of income for more than three million producers and it is highly strategic culture, from the point of view security and sovereignty food. Objectives: The objective of this study is to identify a more productive variety, less susceptible to phytotoxicity of weedkiller treatment and less attacked by diseases under experimental conditions. Methods: Three weeding techniques and three varieties were used in Split-plot design with four repetitions to destroy weeds. Visual diagnosis thanks to precise observations of symptoms, was done in fields to identification of diseases, thereafter incidence and severity were evaluated. Results: Four pathological diseases and five physiological diseases were recorded. The results showed that treatments had not significant effect on growth of maize cultivars, particularly plant height, stem collar diameter and leaves number. The incidence of helminthosporiosis and foliar spots of varieties V2 (variety CMS 8501) and V3 (variety CMS 8704) was significantly higher in plots control (WT0: unweeded) compared in plots weeding with hand and chemical weeding. These results showed that the local variety had the highest severity in all the treatments compared to improve varieties. Conclusions: The local variety was more diseases sensitive than improved varieties. High yields were recorded for improved varieties and low yield for local variety. For hand weeding treatment (WT1) and chemical weeding (WT2) yields were high compared to unweeded treatment (WT0).
Keywords: Zea mays L., diseases, incidence, severity, weeding techniques
