    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 ...

  • Weaving gender into sustainable intensification interventions 

    Fischer, G. (CAB International, 2022-05)
    Sustainable intensification (SI) is understood as increasing productivity without causing harm to the environment. SI can be achieved by introducing more or different inputs (e.g., new knowledge and skills, labor, chemicals, and machinery); a change to higher-yielding crops or varieties, and more productive livestock breeds; a conversion to more productive farming systems (e.g., through irrigation); or a combination of these. This chapter introduces gender concepts in agricultural development and ...
