Cotton is a vital cash crop for smallholder farmers in Mozambique, contributing significantly to rural economies. However, productivity remains below its potential due to factors such as pest infestations, poor soil conditions, and inconsistent agricultural practices. The 2023/24 Determinants of Cotton Yield Study, conducted in Cuamba, Niassa Province, aimed to identify and quantify key factors affecting cotton yield. The study provides evidence-based recommendations for improving productivity and reducing yield losses.
Key Findings
1. Soil Quality and Crop Management
The study revealed that soil conditions play a crucial role in determining cotton yield. Analysis of soil samples across various locations showed low organic matter content and significant variation in phosphorus levels, both of which impact plant growth. The study recommends soil fertility management techniques, including crop rotation and organic matter enrichment, to improve yields. Additionally, proper plant spacing and adherence to recommended planting densities were identified as critical factors in reducing yield losses.
2. Pest Infestation and Yield Losses
Pest infestations, particularly from the red bollworm (Diparopsis castanea) and the American bollworm (Helicoverpa armigera), were found to be major contributors to yield loss. The study demonstrated a 35.1% reduction in yield due to pest attacks during the reproductive phase of the crop. Integrated pest management (IPM) strategies, including timely pesticide application and biological control methods, were recommended to mitigate these losses.
3. Impact of Climatic Conditions
The study found that erratic rainfall patterns and insufficient precipitation negatively impacted cotton productivity. The recorded precipitation levels (192 mm) were significantly lower than the required 650–700 mm for optimal cotton growth. Drought-tolerant cotton varieties, such as CIMSAN2, showed better performance in dry conditions, highlighting the need for climate-resilient agricultural practices.
The 2023/24 Determinants of Cotton Yield Study underscores the importance of soil health, pest management, and climate adaptation in improving cotton productivity in Mozambique. Addressing these challenges requires a combination of best agricultural practices, scientific research, and farmer training programs. Sustainable interventions, such as crop diversification, improved seed varieties, and enhanced pest control strategies, will be critical in ensuring long-term growth and resilience in the cotton sector.
