Abstract
A greenhouse experiment was conducted to evaluate the effect of Bitter leaf mosaic virus (BMV) and Amaranthus mosaic virus (AMV) on growth response, proximate, nutrient composition and sensory acceptability of green amaranth (Amaranthus hybridus L.). The treatments comprised single and double inoculations of A. hybridus with AMV and BM/ while buffer inoculated plants served as control. Data were collected from /" to 8 week after inoculation (WAI) for plant height, number of leaves, and number of leaves with viral disease symptoms. Standard methods of the Association of Official Analytical Chemist were used for determining the proximate composition and sensory acceptability were carried out on the leaves at harvest. The results showed that the significantly highest percentage disease severity at 8 WAI was recorded in plants inoculated with AM! (19.3%) followed by BMI (16.2%) and BMV + AMV (15.1%). The growth parameters from the 5th to the 8th WAI indicated that AMV inoculated plants were the shortest plants (22.6 to 33.7cm) with the significantly lowest number of leaves (6.9 to 23.6cm) compared to the control plants which were the tallest. The analysis showed a depletion of the proximate and mineral contents of the leaves by the viruses. However, the sensory evaluation revealed overall general acceptability of the virus infected plants despite an aversion to the colour.
