Our goal is to improve agronomic practices for peanut production is challenging in areas of southeastern Africa (Zambia, Malawi, and Mozambique). These areas rely upon a single rainy season that historically has seen significant variation in the amount of rainfall and timing of those rains. Linking multiple institutions across three contiguous countries in southeastern Africa permits a more comprehensive evaluation of crop production and pest management strategies over a wide range of weather, soil types, and cultural practices. Collaborations among North Carolina State University, the University of Zambia, the Instituto de Investigacao Agraria de Mocambique, the Universidade Eduardo Mondlane in Mozambique, and the Chitedze Agricultural Research Station, ICRISAT, the Lilongwe University of Agriculture and Natural Resources, and ExAgris in Malawi have all contributed to the development of a useful database in just three years. Experiments included evaluations of varieties, planting date, row spacing, plant populations, gypsum, crop rotation, pest management, and harvest date.
