Abstract:
Sweetpotato yields in sub-saharan Africa is presently restricted by many factors that include crop management practices, low soil fertility, varietal selection, weather condition, soil type, pest and disease pressure among others as opposed to other climes. In view of these, two field trials were conducted during the 2016 and 2017 rainy seasons at the Research Farm Bayero University Kano (11°58' N, 8°25' E, and 457m above sea level) in the Sudan savanna agroecological zone of Nigeria to determine effect of ridge height, vine cutting and vine orientation on growth, yield and nutritional quality of sweetpotato. The treatments consisted of ridge heights (0cm (flat ground), 30cm, 40cm, 50cm and 60cm), vine cuttings (apical, middle and basal) and vine orientations (45°, 90° and 180°) laid out in a split plot design, with the ridge heights and vine cuttings in the main plot and vine orientations in the sub plot and replicated three times Ridging and the vine cuttings (apical) had significant effects on number of branches, chlorophyll content, number of roots per plant, root yield per hectare, where 30 cm ridges however at par with other ridge heights was deduced the best as it is cheaper and easier to produce. The 30cm ridges, apical cuttings and 45° had higher carbohydrate content, while calcium content was higher in plants from 30cm ridges and basal cuttings. Crude fibre content was higher in plants from 40cm ridges and the basal cuttings. For higher root yield therefore, the use of 30cm ridges and apical cuttings is recommended in this agroecological zone.
