“…Tuber yields of other check varieties Antin-1 (12.92 t ha -1 ) and Beta-2 (9.85 t ha -1 ) were only around, respectively, 40% and 25% of their potential yield. Saitama et al (2017) observed the tuber yield of check varieties Antin-1, Antin-2 and Beta-1 of, respectively, 8.86, 11.96 and 33.84 t ha -1 during dry season in East Jawa, which significantly differed from those of the present study, indicating that yield performance of these varieties varied considerably according to the variation in the environmental conditions. Thus, tuber yield of sweet potato is determined by an interaction between genetic and environmental factors as reported in the previous studies (Yusuf et al 2008;Osiru et al 2009;Moussa et al 2011;Haldavanekar et al 2011;Mau et al 2013;Rahajeng and Rahayuningsih 2017).…”

“…Tuber yields of the present orange-fleshed genotypes were much higher than those of orange-fleshed sweet potato evaluated in Blitar (4.2-21.6 t ha -1 ) and Mojokerto (2.1-30.9 t ha -1 ) (Rahajeng and Rahayuningsih 2017b) and ILETRI germplasm collection (0.48-25.84 t ha -1 (Rahajeng and Rahayuningsih 2017a). Saitama et al (2017) reported tuber yield of several Indonesian sweet potato (yellow, orange and purplefleshed) varieties ranging between 8.9-44.8 t ha -1 . Meanwhile, the report on tuber yield of purple-fleshed sweet potato in Indonesia is limited.…”

Abstract. Mau YS, Ndiwa ASS, Markus JER, Arsa IGBA. 2019. Agronomic performance and drought tolerance level of sweet potato hybrids grown in Kupang, East Nusa Tenggara, Indonesia. Biodiversitas 20: 2187-2196. This study was conducted to evaluate agronomic performance and to assess drought tolerance level of purple and orange-fleshed F1 sweet potato hybrids in dryland during dry season in Kupang, East Nusa Tenggara. The study was carried out in Integrated Archipelagic Dryland Field Laboratory of Universitas Nusa Cendana, Kupang, from May to October 2018. Two sets of experiment were conducted, the first was for evaluation of agronomic performance, and the second was for evaluation of drought tolerance of the sweet potato genotypes. The first experiment assessed the agronomic performance of 20 sweet potato genotypes in a Randomized Block Design. The second experiment employed a Split Plot Design consisted of irrigation level as the main plot and sweet potato genotypes as subplot treatments. The main plot consisted of no stress (normal) and water-stressed conditions while the sub-plot comprised of 20 genotypes of the sweet potato. The observed agronomic performance variables included growth and yield parameters. Tuber yields in no stress and water-stressed conditions were observed and used for assessment of drought tolerance. The results showed that, in the agronomic performance experiment, the sweet potato genotypes differed significantly in all the observed agronomic performance variables including growth, yield contributing, and yield variables. UNC2016.Cil/JPV.01 and UNC2016.Cil/JPV.05 were short maturing genotypes with only about 90 days to harvesting while the rest of the genotypes were harvested in 120 to 150 days. The genotypes were also significantly varied in tuber yield; the highest was observed in UNC2016.JPV/KDL.11 (43.38 t ha-1). In the drought tolerance evaluation experiment, tuber yields in no stress and stressed condition were, respectively, 23.42 t ha-1 and 7.08 t ha-1. Six F1 hybrids were classified and selected as drought-tolerant genotypes with high yielding performance in both no stress and water-stressed conditions.

“…Then, Amoatey et al [25] assessed the relationship between sweet potato genotypes on one hand and vegetative plant body morphology and yield on the other, in the coast of Ghana. Saitama et al [26], in Indonesia studied leaf area, leaf area index, total plant dry weight and harvest yield of ten sweet potato varieties in the Rainy season. On his part, Taffouo et al [27] investigated growth and yield aspects of sweet potato in Cameroon while Ramírez et al [28] in Kenyan worked on the effectiveness of the sweet potato plant in utilizing trapped light energy as well as the proportion of same that is transformed into root tubers.…”

Aim: To determine the growth characteristics of five sweet potato varieties on different soil types as well as how they each relates to tuber yield. This investigation will help guide farmers from resource-limited areas to select varieties that grow well in austere soils to produce good yield of tubers, thereby boosting global food security. Study Design: Randomized complete block design (RCBD) with five treatments and three replications. Place and Duration of Study: Experimental field of Bolgatanga Technical University for five months. Methodology: Planting was done by inserting 10 cm length of each 30 cm long soft wood vine cutting into the soil, followed by watering. Five vine cuttings planted per ridge at a spacing of 60cm. Vine cuttings were transplanted in the same order on each ridge. There were 15 plants per treatment, so seventy-five (75) for the five treatments. Results: Analysis of the soil showed sandy loamy soil with suitable pH of 6.05. The Orange flesh and Agric white varieties had the largest and smallest leaf areas of 177.76 cm2 and 110.74 cm2 respectively. Leaf area was positively correlated with root tuber mass in only the Red local variety (r = 0.026). Petiole length of the Orange flesh variety (19.08 cm) was significantly longer than that of the Agric white (13.55 cm, p = 0.02), Agric orange flesh (13.85 cm, p = 0.04), Red skin (11.84 cm, p = 0.00) and Red local (12.18 cm, p = 0.00) varieties. Petiole length was positively correlated with tuber yield in only the Orange flesh variety (r = 204). The Red skin (174.28 cm) and Red local (172.46 cm) varieties had the longest vines than all the rest, though not statistically significant (p = 0.241). Root tuber yield of the five varieties were Agric white (1.22 Kg), Agric orange flesh (1.40 Kg), Red skin (4.27 Kg), Red local (2.96 Kg) and Orange flesh (5.72 Kg), which were significantly different from each other (p=0.05). Conclusion: The Orange flesh variety had the largest leaf area, longest petioles and the highest root tuber mass. On the other hand, the Agric white variety recorded the least Leaf area, Vine length and Tuber mass while the Red skin variety had the shortest Petioles.

Public awareness of foods that have physiological functions for health is increasing. Consumption of orange fleshed sweetpotato not only meets carbohydrate requirements but also beta-carotene which is good for eye health. The aim of this reserach was to evaluate the yield potential and levels of dry matter content of promising clones of orange fleshed sweetpotato rich in beta-carotene. The study was conducted in Malang, East Java in Dry Season II 2016. Genetic materials used were 20 sweetpotato clones, including Beta-1 and Beta-2 varieties as a check. The treatment design used a randomized block design with three replications. The results showed that the clones tested had a potential yield ranging from 20.9 - 35.1 t/ha with an average of 25.2 t/ha. There were three clones had a higher yield potential than the check varieties Beta-1 and Beta-2. Dry matter content ranged from 17.0 - 31.6% with an average of 25.7%. Fifteen clones had higher levels of dry matter content than check varieties Beta-1 and Beta-2. MSU 14018-06, MSU 14001-20 and MSU 14027-02 clones had high yield potential and dry matter content. All three clones have the opportunity to be released as new superior varieties of orange fleshed sweet potato rich in beta-carotene.
