Hermetic storage of maize grain in repurposed food oil containers to control maize weevils
July-September 2021
Insect-related grain loss is a significant problem in Uganda and other countries in sub Saharan Africa. The maize weevil (Sitophilus zeamais Motschulsky) is one of the major insect pests that infests stored maize grain (Zea mays Linneaus). This study demonstrates the feasibility of hermetic or “air-tight” storage for protecting maize from maize weevil damage using low-cost repurposed food oil containers....

A low-cost integrated desalination and irrigation technique tested on dual-purpose sorghum in Turkana County, Kenya
September, 2021
In arid and semi-arid lands, water salinity often restricts plant growth, degrades soils, and even causes irrigation systems to fail, especially in hot climates. Worldwide, it is a “major cause” of the irrigation-induced salinization that had already affected 76 million ha of soil in 1991. Our novel and inexpensive irrigation technique addresses these issues, thus potentially improving the food security of...
