Editorial

Welcome to issue 19(3) of the Journal of Agricultural & Food Information! The issue opens with a Commodity of the Quarter column by Alexandra Hauser on peanuts (groundnuts) which, we learn, are really legumes—not nuts—and have been cultivated since the late Neolithic and early Bronze Ages! Peer-reviewed contributions include a mixture of offerings from the information science and extension realms. In the lead article, Maayan Zhitomirsky-Geffet and Chaim Z. Mograbi present a methodology for building an agricultural ontology by individuals with no professional training in ontology construction. In their study, domain experts and non-experts successfully collaborated in creating an ontology for crop-pest control through a user-friendly, graphical tool. Their approach may serve as a model for the creation of ontologies in other fields. Next, Ahmed S. F. Ahmed, Sai Vanga, and Vijaya Raghavan highlight global publication trends in biochar research, based on data collected from the Web of Science. Their bibliometric analysis documents an exponential increase in published articles, reflecting growing interest in biochar as an agricultural soil amendment and an approach to carbon sequestration. The impact of information on decision-making is the focus of a field experiment conducted by Julius Okello, Carl Johan Lagerkvist, Penina Muoki, Simon Heck, and Gordon Prain in Kenya. The authors investigated consumers’ willingness to purchase and consume biofortified foods and show that positive information can help overcome negative perceptions and misconceptions and promote acceptance of foods such as orange-fleshed sweetpotato that can help combat micronutrient deficiencies. The final three articles examine farmers’ information needs and preferred sources of information to inform extension practice. Juliana Iwuchukwu, John Eke, and Charles Udoye surveyed crayfish farmers in Nigeria, most of whom have no contact with extension and limited to no access to agricultural information. The authors document a need for adaptation strategies with respect to the effects of climate change on aquatic animals and training in modern methods of harvesting, processing, packaging and marketing to promote development of the crayfish industry. Mohammed Sanusi, Abiodun Omokhudu, and Florence Adeloye assessed Nigerian date farmers
