Autor: Alene, A.

The question of whether the intended gains in food production from new varieties have actually been realized by poor farmers has received little or no attention in the literature. This paper used a stochastic frontier efficiency decomposition methodology to derive the technical, allocative and ec...


Alene, A.[Unexploited food production potentials of new varieties: evidence from hybrid maize production in western Ethiopia]Unexploited food production potentials of new varieties: evidence from hybrid maize production in western Ethiopia

Conventional farmer efficiency studies have addressed the question of whether possibilities exist for inexpensive gains in production through better use of traditional technology. The question of whether the production potentials of new seed technologies have been fully exploited by poor farmers ...

Maize (Zea mays L.) is a major staple food and cash crop in sub-Saharan Africa (SSA). However, its production and productivity are severely constrained by drought. A total of 120 single-cross hybrids and an open-pollinated control variety were evaluated for 2 years at two locations under managed ...


Akaogu, I.C.Badu-Apraku, B.Adetimirin, V.O.[Combining ability and performance of extra-early maturing yellow maize inbreds in hybrid combinations under drought and rain-fed conditions]Combining ability and performance of extra-early maturing yellow maize inbreds in hybrid combinations under drought and rain-fed conditions

Striga spp. are obligate root hemiparasites that constrain cereal production in sub-Saharan Africa. Although purple witchweed [ Striga hermonthica (Delile) Benth.] and Asiatic witchweed [ Striga asiatica (L.) Kuntze] infect all cereal crops, maize ( Zea mays L.) is particularly vulnerable to thei...

The moist savannas of West and Central Africa have great potential for maize grain production due to high levels of radiation and reduced incidence of pests and diseases. However, soils in this zone are generally low in organic matter and cation exchange capacity in addition to land use intensifi...


Ajala, S.O.Menkir, A.Kamara, A.Y.Alabi, S.O.Abdulai, M.S.[Breeding strategies to improve maize for adaptation to low soil nitrogen in West and Central Africa]Breeding strategies to improve maize for adaptation to low soil nitrogen in West and Central Africa

Aflatoxin contamination of major food crops is a serious problem in Senegal. Maize and sesame samples were collected during a survey in five districts located in two agro-ecological zones in Senegal to determine levels of aflatoxin contamination and the distribution and toxigenicity potential of ...

Guzmán Prada, Diego AlexanderRodríguez Chalarca, JairoValencia Cataño, Sandra Jimena[Identification of Lepidoptera Larval Stages - A Maize Pest]Identification of Lepidoptera Larval Stages - A Maize Pest

Aflatoxin contamination in maize and groundnut is perennial in Ghana with substantial health and economic burden on the population. The present study examined for the first time the prevalence of aflatoxin contamination in maize and groundnut in major producing regions across three agroecological...
