In the last six to eight years, farming systems adaptive research has contributed much to the understanding of maize production constraints on smallholder farms in southern Africa. It has contributed less to the development ...

Planting strategies of smallholder farmers are examined in two contrasting study areas in Zimbabwe, Mangwende (sub-humid, natural region II) and Mudzi (semi-arid, natural region IV). to show that farmers regard maize as a ...

Maize accounts for 70% of Zimbabwe's cereal growing area. Its productivity, particularly in the communal areas, is limited by both soil and moisture constraints. Most soils in communal areas are coarse-textured sands derived ...

During the 1989-90 and 1990-91 cropping seasons, researchers from CIMMYT and the Evaluation Units of the Malawian Ministry of Agriculture (MOA) collected data to profile farmers' adoption behavior and varietal choices, and ...

Tecnologías para conservación y productividad: sustitutas o complementarias. El aumento de la productividad y la conservación de los recursos se anuncian como objetivos deseables de la investigación agrícola pero frecuentemente ...

Breeding for resistance to rust diseases in wheat is an example of productivity maintenance research. Productivity maintenance research is necessary to avoid contractions in the wheat supply curve that result from changes ...

Wheat ( Triticum spp.) is a major crop grown in northwestern Ethiopia. The primary wheat production constraints in this area include low soil fertility, use of unimproved and disease-susceptible varieties, and high weed ...
