Rainfed crop management systems need to be optimized to provide more resilient options to cope with projected climatic scenarios forecasting a decrease in mean precipitation and more frequent extreme drought periods in Mexico. Soil water content (0 60 cm) was measured during three crop cycles in ...

Phytotoxic effects ofGliricidia prunings were tested on maize seedlings in the laboratory and on maize and cowpea seedlings in the field. In the laboratory test, growth of maize seedlings was significantly depressed by addition of leachate ofGliricidia prunings. In the field, leaf, chlorosis of m...

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...

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 ...

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...

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 ...

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...

Eighteen S1 lines of maize (Zea mays L.) derived from a low nitrogen tolerant pool and two inbred lines were evaluated for agronomic performance under moderate N conditions in the southern Guinea savannah of Nigeria. Generally, the breeding lines differed in yield, growth, vertical rootpulling re...
