Effects of potassium deficiency, drought, and weevils on banana yield and economic performance in Mbarara, Uganda
Publicado 2004“…K deficiency did not only reduce bunch weight, but also increased cycle length, resulting in a significant (r2= 0.57) correlation between these two crop parameters. Mean weevil pressure was too low (< 4%) to result in significant yield loss, but maximum bunch weight was less than 50% in plants with large corm damage (>8%). …”

Introducing co-composting to fecal sludge treatment plants in Benin and Burkina Faso: a logistical and financial assessment
Publicado 2020“…RR for reuse can turn sludge disposal from a cost into a source of revenue with co-benefits for farmers and the environment, thereby reducing the pressure on tipping fees. The probability of the added co-compost production being financially viable on its own was estimated for all the study sites, indicating an earliest breakeven point after 5 to 8 years.…”
