Poster: Growth and yield responses of orange-fleshed sweetpotato varieties to propagules sources in rainforest and savannah zones of Nigeria

In Nigeria, many farmers use planting material from previous seasons. As it is a vegetatively propagated crop, sweetpotato vine cuttings are prone to disease and pest buildup which is transferred from one generation to the next resulting in low yield (6-7ton/ha) in farmers field. This poster depicts a field trial was conducted over two seasons (2013 – 2014) at NRCRI, Umudike and Nyanya stations. The two areas represent rainforest and savannah -ecological zones respectively, to examine yield variation from different propagule sources and varieties. The trial was laid out as a 4 x 2 factorial in a randomized complete block design replicated three times. The treatments comprised two improved Orange-fleshed sweetpotato (UMUSPO1 (KingJ) and 3 (Mothers delight)) in combination with 4 propagule sources ((net tunnel, Negative selection, regrowth and regrowth treated with carbonfuran).
