Rice straw and sweet potato vines are the main by-products of agricultural crops, and their disposal creates problems for the environment in the south of China. In order to establish an easy method for making rice straw silage successfully, experiments were conduct to evaluate fermentation quality and nutritive value of rice straw silages ensiled with or without sweet potato vine. Paddy rice straw (PR) and upland rice straw (UP) were ensiled alone or with sweet potato vines (SP) by a ratio of 1:1 (fresh matter basis), over 3 years. Compared with rice straw silages ensiled alone, the mixed-material silages (PR + SP, UR + SP) showed higher fermentation quality with lower propionic acid content and NH -N ratio of total N, and higher (P < 0.05) concentrations of lactic acid and acetic acid, resulting in decrease (P < 0.05) of dry matter loss and higher (P < 0.05) in vitro ruminal dry matter digestion. When the fermentation quality, chemical composition and in vitro rumen fermentation characteristics were considered, ensiling would be an effective way of utilization of rice straw and sweet potato vines in the regions where rice and sweet potato are harvested at same season, and the sweet potato vines have the potential to improve rice straw fermentation quality with low water soluble carbohydrate content in south of China.

“…Each component of this multi-faceted system might require varying levels of water inputs and will have varying cost and benefit implications. In terms of sweet potato, researchers have claimed that the diversification and advances in the technology applied to its production have been considerable in the last decades leading to a myriad of opportunities, from energy production to providing raw material for starch, flour, juice, bread, liquors, pigments, candy, and various uses in the cosmetic industry, etc., [117].…”

Understanding the Implications of Alternative Bioenergy Crops to Support Smallholder Farmers in Brazil

et al. 2020

Smallholders constitute more than three quarters of the world’s farmers, and despite their numbers, they commonly lack opportunities to advance their development status. Bioenergy production and consumption can help sustain smallholders’ energy needs and generate employment and income, but it also raises concerns over social justice and equity, especially where crops used for bioenergy could also be used for food. This perspective paper is grounded in a literature review related to three different crops in Brazil: sugarcane, landrace maize and sweet potato. It seeks to determine if these crops offer the potential to support smallholder farmers’ development in a more equitable way, focusing on opportunities for their use in bioenergy. We review the literature to identify policies shaping the smallholder development context in relation to these crops, assessing whose knowledge informs policy and institutional decision making, and highlighting the policy attention afforded to the different crops from different sectors. We further evaluate the literature on each crop in relation to water use and calorific value (i.e., food and energy). Our review indicates that while sugarcane has received the most policy and institutional attention, its development is largely anchored in research and development investments that support large-scale commercial farms and agri-businesses. Smallholders have not benefited or had the opportunity to engage in relevant policy decision making for sugarcane cultivation. At the same time, smallholders hold valuable untapped knowledge on the cultivation of sweet potato and landrace maize, both of which have the potential to generate development opportunities for smallholders. Our review suggests that the environmental impact of landrace maize and sweet potato in terms of water use is significantly lower than sugarcane, while they can generate more calories for energy or food consumption and offer diversification opportunities. Despite that these alternative crops offer considerable untapped potential to support rural development, more research is still needed to harness these benefits. Changes are needed to address inequities in policies, institutions and the types of knowledge informing decision making. Such changes need to afford smallholder farmers greater recognition and participation in decision making, so that the distribution of benefits from the three study crops can reach them to support their development better.

“…It is considered the 7th most essential staple food crop in the world with reference to production [19]. Sweet potato is cultivated extensively and consumed in tropical and subtropical regions specifically in Sub-Sahara Africa, East Asia, and the Pacific Islands [20,21] with about 95% of the production mainly from Asia and Africa [22]. Globally, Ipomoea batatas is considered as a major staple crop especially in developing countries [23].…”

Sweet potato (Ipomoea batatas (L.) Lam.) has several phytochemicals including anthocyanin that provide many special health-promoting functions as well as other functional components. Sweet potato is thought to be a health-giving food owing to the numerous diversities of natural products, especially antioxidants. Anthocyanins are natural hydrosoluble pigments which give the purple, blue and red colouration evident in fruits, leaves, flowers, and storage organs. Anthocyanins are beneficial to human health due to their potent antioxidative properties which protect against several chronic disorders, thus a valuable constituent in the human diet. The pathway for biosynthesis of anthocyanin has been clearly defined with its key regulatory genes identified and segregated in diverse species.Cyanidin or Peonidin 3-sophoroside-5-glucoside with associated acylated derivate are the two primary anthocyanins identified in purple-fleshed sweet potato. Anthocyanins in sweet potato are of great importance to plants, animals, humans and possess scientific benefits as well. This article provides a summary of current findings on the function, structure, and biosynthesis of anthocyanin in sweet potato.
