Abstract
Summary: Application of advanced agronomic practices may affect the sensory attributes of plant products. The study determined the trader physical acceptability of farmer preferred African eggplant (nakati) genotypes (E11, E15 and E16); and later studied the impact of bio‐control treatments; Trichoderma spp (TRI). and Arbuscular Mycorrhizal Fungi (AMF) on consumer sensory appeal of genotypes using standard sensory evaluation methods. The trader acceptability of genotypes based on leaf number, succulence, smoothness, colour, and shininess were significantly different; except for the hard‐textured leaves of E11 (P ≤ 0.05). Leaf appearance (E11) and stalk‐leaf quantity (E15 and E16) were preferred by high‐end and low‐end markets, respectively. Consumer sensory acceptability of bio‐control‐treated samples, above 85% of E15 and E16 was liked based on reduced bitterness (P ≤ 0.05). Using descriptive sensory tastes, results showed that soil bio‐control treatment with TRI during the light rain season significantly improved the palatability of E15 and E16. Therefore, use of TRI during light or dry season improves sensory appeal of nakati.
