Forty weaned rabbits (8 weeks old) of mixed sexes and breed, with an average initial live-weight 680g, were used in a nine-week feeding trial to evaluate their performance on diets which sun-dried sweet potatoe tuber meal (Ipomoea batatas) was included at the rate 0, 10, 20, 30 40% levels CP Isonitrogenous diets. Performance parameters showed that feed intake, weight gain ratio not significantl...

Sustainable weed management strategies are essential to reduce chemical and labor inputs. This study aimed evaluate the effect of water extracts from sweet potato [Ipomoea batatas (L.) Lamarck] on seed germination Ageratum conyzoides L. under controlled conditions. The aqueous was produced plant parts i.e., roots, stems, leaves at concentrations 0.025, 0.050, 0.075, 0.100 g·mL-1. results showed...

Three hundred and ninety-four sweet potato accessions from Latin America and East Africa were screened by polymerase chain reaction (PCR) for the presence of begomoviruses, and 46 were found to be positive. All were symptomless in sweet potato and generated leaf curling and/or chlorosis in Ipomoea setosa. The five most divergent isolates, based on complete genome sequences, were used to study i...

Abstract Fertilizer-N strongly limits non-leguminous crop yields; however, sweet potato ( Ipomoea batatas ) is an exception, likely due to its ability acquire atmospheric N 2 via endophytic diazotrophs. Using Raman spectroscopy, we found that in 15 -fed potato, some bacteria contained N, providing direct evidence of fixation planta . To assess -fixing capability, pot experiments were conducted ...

Sweet potatoes (Ipomea batatas L.) are grown extensively, in tropical and temperate regions, and are important food crops worldwide. In Korea, potyviruses, including Sweet potato feathery mottle virus (SPFMV), Sweet potato virus C (SPVC), Sweet potato virus G (SPVG), Sweet potato virus 2 (SPV2), and Sweet potato latent virus (SPLV), have been detected in sweet potato fields at a high (~95%) inc...

Sweet potato (Ipomoea batatas L.) is an important starch-producing crop used worldwide. However, few studies have been conducted on the energy efficient, cost benefit, and greenhouse gas (GHG) emissions of sweet production. To address this issue, data were collected using a questionnaire for face-to-face interviews 78 growers 74 reference (i.e., rice, maize, potato) in Guangdong province. Resul...

Objective: The focus of this study was to evaluate the yield and stability of superior sweet potato cultivars for release in Kenya. This is the first attempt to document experimental results that have led to the first and so far only sweet potato variety release in Kenya. Methodology: Ten national performance trials laid out as randomized complete block designs were performed on 14 sweet potato...

Sweetpotato (Ipomoea batatas) is an important root crop in Uganda, where yield potential and quality attributes have not been fully exploited due to limited breeding efforts and poor knowledge on the inheritance of some of its agronomic traits. A study was carried out at Makerere University to phenotypically characterise selected sweetpotato cultivars with special reference to sweet potato viru...
