Sensory and Nutritional Quality of Cookies Supplemented with Wheat Bran and Lerotse (Citrullus lanatusvar.citroides) Pulp from Botswana
(Asian Food Science Journal, 2025-06-03)Lerotse or Kalahari melons which are usually planted as ground cover in crop fields in Botswana are rich in potassium, carotenoids and citrulline. However, they are undervalued and often go to waste. As a strategy of value ... -
Nanotechnology in agriculture: Exploring the influence of calcium carbonate nanoparticles on tomato leaf and fruit metabolomic profiles.
(Elsevier B.V., 2025-05)Plant growth and development require various macronutrients such as calcium for the synthesis of secondary metabolites. One of the main factors hindering tomato development and fruiting is calcium deficiency. However, ... -
Phenotypic plasticity and genetic variation of Prosopis juliflora (Sw.) DC. across diverse rangelands in northeastern Ethiopia
(Springer Science and Business Media Deutschland GmbH, 2025-01-10)Introduction: Prosopis juliflora (Sw.) DC. substantially threatens dry rangelands due to its invasive attributes, exacerbated by climate change, land-use practices, and anthropogenic activities. Despite the urgent need to ... -
Distribution, traditional utilization, processing, and health benefits associated with the consumption of morama bean [Tylosema escululetum (Burch.)]: a survey from selected districts of Botswana.
(BioMed Central Ltd, 2025-02-03)Morama bean [Tylosema escululetum (Burch.)] is a nutrient-dense underutilized legume that can address protein-energy and micronutrient malnutrition in developing countries. An ethnographic study using a snowball sampling ... -
