| Maize is the major food crop grown in the coastal region of Kenya and constitutes a major component of the diet of the population in the region. However, average yields are far below the potential for the region and low production levels create serious food deficits. Over the years, new technologies have been introduced but adoption has remained low, especially for fertilizer. This paper examined current maize-farming practices and technological and socioeconomic factors that influenced adoption in the Kilifi and Kwale Districts of the Coast Province, that together account for half of maize production in the region. The study found low adoption levels for improved maize varieties and technology, especially fertilizer, among farmers in the area. Farmers... |

| The publication describes outcomes of a study conducted in 2007/08 to analyze the bottlenecks affecting the production and deployment of maize seed in eastern and southern Africa. The objectives of the study were to provide a better understanding of the factors limiting the production and deployment of improved maize seed in Africa, and to contribute to increasing the efficiency of variety release, seed production and seed dissemination for new drought tolerant maize varieties. The study identified a number of institutional bottlenecks affecting the maize seed value chain, in particular in the area of policy, credit availability, seed production, germplasm and marketing. To address these bottlenecks and improve the efficiency of seed production and... |

| Objetivando-se indicar cultivares de cebola mais produtivas e de melhor qualidade de bulbos para a regiao semi-arida, conduziu-se um ensaio no Projeto Bebedouro, Petrolina-PE, de abril a agosto de 1997. O delineamento experimental foi de blocos ao acaso com quatro repeticoes e as seguintes cultivares: Granex-429, Texas-Grano-PRR, Brownsville, Houston, Texas Grano-502, Texas Grano-438, Conquista, Composto IPA-6, Belem IPA-9, Franciscana IPA-10, Valeouro IPA-11, Alfa Tropical (CNPH-6179), CNPH-5898, CNPH-6074, CNPH-6040, CNPH-6067, Bola P. EMPASC, XP-1, XP-2 e Crioula Mercosul. A produtividade de bulbos comerciais variou de 21,41 a 61,78 t/ha, destacando-se as cultivares Texas Grano-PRR (61,78t/ha), Granex-429 (58,28 t/ha), Texas Grano-438 (56,97 t/ha),... |
