Maize became increasingly important in the food
security of Ethiopia following the major drought and famine
that occurred in 1984. More than 9 million smallholder house-
holds, more than for any other crop in the country, grow maize
in Ethiopia at present. Ethiopia has doubled its maize produc-

Factors that transformed maize productivity in Ethiopia
Estimates of combining abilities and heterosis of inbred lines are imperative for selection of suitable parents of maize hybrids. This study examined the combining ability of 24 drought-tolerant maize inbred lines, 12 each from International Centre for Maize and Wheat Improvement (CIMMYT) and Int...

Sustainable resource management is the critical agricultural research and development challenge in sub-Saharan Africa. The accumulated knowledge on soil management gathered over the last 10 years, combined with solid crop improvement and plant health research at farmers’ level, has brought us to ...

The management of the fall armyworm Spodoptera frugiperda in maize field necessitates the use a big quantities of insecticides and sometimes the use of multiple types and formulations of chemicals. The use of insecticides in crops is associated with environmental risks and health hazards to both ...

A major problem that usually confronts the breeder is ensuring that there is sufficient genetic variability in a population for the trait being improved because this determines the breeding schemes to use for improvement and whether or not sufficient progress could be made. Three hundred full-sib...

Genetic variability for grain yield and components in an early tropical yellow maize population under Striga hermonthica infestation
Striga hermonthica is a parasitic weed that attacks maize, sorghum and other staple cereal crops and has long been considered one of the greatest biotic constraints to cereal production in Africa. Use of resistant or tolerant maize varieties, a maize–legume rotation using trap crops that stimulat...

A participatory approach to increasing productivity of maize through Striga hermonthica control in Northeast Nigeria
Several maize near-isogenic inbred lines were subjected to comparative proteomics to identify kernel proteins associated with resistance. These lines were developed in Nigeria through a joint project between ARS-SRRC and the International Institute of Tropical Agriculture. The goal of this projec...
Development of pro-vitamin A (PVA) biofortified staple crops has been promoted as an option for addressing vitamin A deficiency in humans. Recently, crtRBI, lcyE and zep1 genes of carotenoid biosynthesis pathway have been identified as contributors to PVA accumulation in maize endosperm. High phe...

Influence of nitrogen fertilization on the performance of early and late maturing maize varieties under natural infestation with Striga hermonthica (Del.) Benth
Striga hermonthica (Del.) Benth. is a parasitic weed that attacks maize, sorghum, and other staple cereal crops in the West African savannas. It is widely believed that Striga thrives best in areas of low soil fertility. This study was conducted to determine the effects of nitrogen (N) fertilizat...
