En el Perú existen 9 DO, sin embargo, en 8 de ellos ninguna ha avanzado más allá de obtener el reconocimiento oficial. El estudio busca profundizar la comprensión de los procesos, resultados, beneficios alcanzados por los actores de la cadena de valor en relación a la generación de valor agregado...

Weed abundance in cereal-based systems has increased in recent years across sub-Saharan Africa for smallholder farmers (cultivating less than two hectares). Smallholders can employ numerous practices to control weeds such as intercropping cereal crops with legumes. We conducted a review to identi...

Early-maturing provitamin A (PVA) quality protein maize (QPM) hybrids with combined drought and low soil nitrogen (low-N) tolerance are needed to address malnutrition and food security problems in sub-Saharan Africa (SSA). The current study's objectives were to (i) examine combining ability of se...

The GGE biplot tool has potential for determining combining ability effects, identifying distinct heterotic groups and efficient testers in a line × tester study. However, its use for such analysis has not been adequately explored. The objectives of this study were to (i) assess combining ability...

Afternoon soil temperature of about 39°C observed at 5 cm depth under sole cassava (Manihot esculenta Crantz) early in the growing season was reduced by respectively 1.0, 1.3, 3.0 and 4.4°C by intercropping with maize (Zea mays L.), maize/okra (Abelmoschus esculentus Moench), maize/ egusi melon (...

Field experiments were conducted in the dry season of 1985–86 and the first and second rainy seasons of 1986 at Ibadan, Nigeria, to assess the level of damage and yield reductions caused by Eldana saccharina Walker to maize. Grain weight per plant in artificially infested plots was up to 36% lowe...

The climate of the West African Sudan savannah (annual rainfall of 600–900 mm and a monomodal rainy season of 3–4 months) is characterized by frequent long- and short-term droughts. Crop growth in the Alfisols and associated soil groups is further constrained by soil compaction, low soil fertilit...

Reports the findings of a mission carried out by the International Institute of Tropical Agriculture in Zimbabwe to gather genetic resources of cowpea, rice, bambarra groundnut and their wild relatives. 461 samples of 365 species were collected. Sampling was made over 140 sites of both natural ve...
The effect of alley cropping with seven combinations of Acioa and Leucaena hedgerows and a control (no hedgerow) treatment on sequentially cropped maize and cowpea was studied in 1985 and 1986. The trial was carried out on an Alfisol in the humid zone of southwestern Nigeria. Hedgerows were estab...
