IITA Bibliography is a collection of agricultural research publications produced by IITA scientists, research fellows, and students from 1972 to date. The collection includes journal articles, books and book chapters, conference proceedings, training and extension materials, theses, and other publications. IITA conducts research in these thematic areas: biotechnology and plant breeding, natural resource management, social science and agribusiness, plant production and plant health, and nutrition and human health.

  • Participatory action research, social networks, and gender influence soil fertility management in Tanzania 

    Mponela, P.; Manda, J.; Kinyua, M.; Kihara, J. (2022)
    Transformation of knowledge systems and fostering learning among smallholder farmers such as through participatory action research (PAR) is key to agricultural growth in rural sub-Saharan Africa. We investigate how PAR influences uptake/use of integrated soil fertility management (ISFM) while accounting for gendered, bonding and bridging social capital. Stratified by engagement in a mother-baby PAR and by resource endowments, 607 smallholder farmers were sampled from northern Tanzania. Binary ...
  • Identification of QTL for perenniality and floral scent in cowpea (Vigna unguiculata [L.] Walp.) 

    Lo, S.; Fatokun, C.; Boukar, O.; Gepts, P.; Close, T.J.; Muñoz-Amatriaín, M. (2020-04-28)
    Perennial habit and floral scent are major traits that distinguish domesticated cowpeas from their wild relatives. However, the genetic basis of these two important traits remains largely unknown in cowpea. Plant longevity, a perenniality-related trait, and floral scent, an outcrossing trait, were investigated using a RIL population derived from a cross between a domesticated and a wild cowpea. QTL analysis revealed three significant loci, one on chromosome 8 associated with plant longevity and ...
  • Response of cassava cultivars to African cassava mosaic virus infection across a range of inoculum doses and plant ages 

    Houngue, J.A.; Pita, J.S.; Ngalle, H.B.; Zandjanakou-Tachin, M.; Fotso Kuate, A.; Cacaï, G.H.T.; Bell, J.M.; Ahanhanzo, C. (2019-12-23)
    Cassava production in Africa is constrained by cassava mosaic disease (CMD) that is caused by the Cassava mosaic virus (CMV). The aim of this study was to evaluate the responses of a range of commonly cultivated West African cassava cultivars to varying inoculum doses of African cassava mosaic virus (ACMV). We grafted 10 cultivars of cassava plants with different inoculum doses of CMV (namely two, four, or six CMD-infected buds) when the experimental plants were 8, 10, or 12 weeks old, using ...
  • Gender differences in technology adoption and agricultural productivity: evidence from Malawi 

    Hirpa Tufa, A.; Alene, A.; Cole, S.M.; Manda, J.; Feleke, S.; Abdoulaye, T.; Chikoye, D.; Manyong, V. (2022-11)
    It is widely recognized that female farmers have considerably less access to productive assets and support services than male farmers. There is limited evidence of gender gaps in technology adoption and agricultural productivity after accounting for the differential access to factors of production between males and females. This study investigates the gender differences in the adoption of improved technologies and agricultural productivity in Malawi using nationally representative data collected ...
  • Combining ability of extra‐early biofortified maize inbreds under Striga infestation and low soil nitrogen 

    Oyekale, S.A.; Badu‐Apraku, B.; Adetimirin, V.O. (2020-07)
    Striga hermonthica (Del.) Benth parasitism, low soil N, and nutritional deficiencies of normal‐endosperm maize (Zea mays L.) threaten maize yield and exacerbate nutritional problems in sub‐Sahara Africa (SSA). This study was conducted (a) to evaluate genetic variation among extra‐early maturing maize hybrids with provitamin A and quality protein characteristics, (b) to investigate gene action governing the inheritance of Striga resistance, grain yield, low N tolerance, and other measured traits ...
