Combined use of improved maize hybrids and nitrogen application increases grain yield of maize, under natural Striga hermonthica infestation
(2024)Striga hermonthica (Del.) Benth infestation is one of the major constraints to maize production in the Nigeria savannas. The application of nitrogen fertilizer to Striga-resistant hybrids may reduce Striga infection and increase grain yields. The objective of this study was to assess the performance of six maize hybrids at low (30 kg ha−1) and high (120 kg ha−1) nitrogen application under natural infestation with Striga in northern Nigeria in 2014 and 2015. The two nitrogen rates and the six hybrids ... -

Genetic progress in cowpea [Vigna unguiculata (L.) Walp.] stemming from breeding modernization efforts at the International Institute of Tropical Agriculture
(2024-05-22)Genetic gain has been proposed as a quantifiable key performance indicator that can be used to monitor breeding programs’ effectiveness. The cowpea breeding program at the International Institute of Tropical Agriculture (IITA) has developed and released improved varieties in 70 countries globally. To quantify the genetic changes to grain yield and related traits, we exploited IITA cowpea historical multi environment trials (METs) advanced yield trial (AYT) data from 2010 to 2022. The genetic gain ... -
Wheat technology toolkit catalogue: Clearinghouse technical report series 011
(Technologies for African Agricultural Transformation, 2021-09)This catalogue describes a series of technologies related to the modernization of wheat production in Africa. It is based on the combined efforts of the Project Platform for Agricultural Solutions (ProPAS), an information portal, and the Technologies for African Agricultural Transformation (TAAT), a large collaborative program that is deploying agricultural solutions across the continent. Both activities are addressing the imperative to better connect proven technologies to those who need them, ... -
Shifting focus from external to in situ organic resources – The redesign of four tropical long-term experiments
(2024-04-30)Long-term experiments (LTEs) are critical for evaluating strategies that can maintain or increase crop yields, soil fertility and soil organic carbon (SOC), and help adapt to climate change. Yet, scientific knowledge is advancing and research questions are evolving. Therefore, it is important to review the objectives of LTEs over time. A change in their design may be necessary to keep the experimental treatments scientifically interesting, innovative, and relevant in the context of evolving ...
