    Agre, A.P.; Mondo, J.; Edemodu, A.; Matsumoto, R.; Asiedu, R.; Akoroda, M.O.; Bhattacharjee, R.; Gedil, M.; Adebola, P.O.; Asfaw, A. (Springer, 2022-11-01)
    Yam (Dioscorea spp.) is an important crop providing food, income and medicine in tropics and subtropics. Major yam species in West Africa such as D. alata and D. rotundata are subject to several biotic and abiotic stresses throughout the cropping cycle and post-harvest periods, resulting in substantial tuber yield and quality trait losses. Abiotic stresses (heat, drought, low soil fertility, salinity, waterlogging, etc.) are currently exacerbated by the climate change effects. Yet, limited efforts ...

    Quality phenotype and genotype data are important for the success of a breeding program. Like most programs, African breeding programs generate large multi-disciplinary phenotypic and genotypic datasets from several locations, that must be carefully managed through the use of an appropriate database management system (DBMS) in order to generate reliable and accurate information for breedingdecisions. A DBMS is essential in data collection, storage, retrieval, validation, curation and analysis in ...
  • Opportunities for better phosphorus use in agriculture 

    Masso, C.; Zhang, F.; Adhya, T.K.; Blackwell, M.S.A.; Macintosh, K.A.; Johnes, P.J.; Haygarth, P.M.; Withers, P.; Feng, G.; Li, H.; Zhang, C.; Wu, J.; Shen, J.; Stutter, M.; Cheng, L.; Brownlie, W. (UK Centre for Ecology and Hydrology, 2022-05)
    Low phosphorus use efficiency (~20%) and high phosphorus losses from agricultural land to waterbodies is a growing global problem and exacerbated by climate change and rainfall extremes. Fertiliser use can be optimised and should consider all nutrients. Widespread soil phosphorus testing is required. In some regions appropriate control limits on phosphorus inputs will be needed, whilst in others an increase in P inputs will be required to improve/maintain agricultural productivity. An integrated ...
