This book was released on 2012 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eating harbits of people keeps on changing over time so to the climate, calling for new inovertive technologies to adress the situation. In Kenya intensive production of sweet potato is constrained by lack of improved varieties, pests, diseases and scarcity of land. In this study 11 improved sweetpotato varieties; Kemb10, SPK004, Mugande, Namaswakhe, K117, Polista, Bungoma, Odinga, 292-H-12, Zapallo and Nyathi Odiewo (Improved), were tested against 4 popular farmer varieties; Nyathi Odiewo (local), Jayalo, Amina and Kuny kibuonjo. The experiment model was mother and baby trial with farmers' involvement. Yields, diseases, pests, consumer preference on market were evaluated. Analysis of variance done. Significant differences and means separated by least significant differences. Significant differences in yield, preference observed. Newly introduced sweet potato varieties had potential for improving consumers' conditions. Involvement of farmers is crucial in selection of preferred sweet potato varieties. The book is recommended for Research Scientists Agricultural Extension workers University and college students, farmers, traders, consumers of sweetpoato and other general readers

This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sweet potato (Ipomoea batatas Lam.) is the seventh most important food crop among the root and tuber crops grown in the world which is widely cultivated in tropic, sub tropic and warmer temperate regions. A wide variation exists among sweet potato varieties. The molecular markers Is an important genetic diversity analysis tool for enhancing duplicates identification. The samples were collected based on an elaborative iterative survey as well as traditional knowledge from local people. Thirteen different varieties Ipomoea batatas Lam. varieties (Kuravanpady 1, Kuravanpady 2, Jellipara 1, Jellipara 2, Kottathara, Kadanadu, Kanaka, Aruna, Kanjagad, Cherukizhangu 1, Cherukizhangu 2, Thodupuzha. Palakkad) were used for morphological characterization. Morphological data were collected 60 days after planting based on the descriptors for sweet potato (IBPGR, 1991) in all the 13 samples. The variable scored were twining, plant type, ground cover, vine inter node, vine pigmentation, vine tip pubescence, mature leaf shape, mature leaf size, abaxial leaf vein pigmentation, foliage colour, petiole length, petiole pigmentation, storage root and skin colour. Molecular characterization could be more effectively used in screening varieties among sweet potatoes if coupled with other molecular markers especially ISSR, matK and rbcL markers.

Download or read book Growing and Handling Sweet Potatoes in California Classic Reprint written by Donald Rockwell Porter and published by Forgotten Books. This book was released on 2017-11-10 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Growing and Handling Sweet Potatoes in California The term seed as applied to sweet potatoes is a misnomer, just as in the case of Irish potatoes. True seed, developing from flowers and fruit, is seldom seen in the United States, although it has been known to form in southern Florida. Occasionally sweet potatoes bloom in southern California, but seed is rarely formed. However, seed has such a universal meaning among growers that it will be used in this discussion to mean the enlarged portions o-f the root, commonly known as sweet potatoes. Probably one of the limiting factors in the production of a profitable crop of sweet potatoes is the inability to secure good seed in those states where seed certification is not prao ticed. In California neither the demand for certified seed nor the acreage grown at present seems to justify certification. With pro-per precautions it is possible for the grower to select high quality seed from his own fields. The sweet potato itself consists of a root, originally a fibrous feeding root, which in the process of development has thickened for a greater or less distance from the central stem. On each such thickened root, or potato, are found four rows of lateral fibrous feeding roots, which usually disappear before the crop is mature, leaving only slight depressions where they were attached. Fro-m the neighborhood of the root scars, adventitious buds originate and under favorable growing conditions, sprouts are formed. These sprouts have an independent root system and are only weakly connected with the mother potato, fro-m which, however, they derive most of their nourishment. Until they are separated and set. In the Open field. The sweet potato has no true rest period, for the sprouts may start growing at any time under suitable moisture and temperature conditions and often do so in the field when harvesting is delayed and in the storage house in the later part of the storage season.

Download or read book Food Security for Papua New Guinea written by R. M. Bourke and published by . This book was released on 2001 with total page 916 pages. Available in PDF, EPUB and Kindle. Book excerpt: People have adequate food security when households have the capacity to access sufficient food at all times, either through self-production or through market purchases. Overall, food security is high in PNG as most rural people have access to land and can grow most of their food requirements. The food security situation is considerably better in PNG now than it was before the Pacific war. This is because high-yield staple crops have been adopted and people have access to cash income that can be used to purchase food. The adoption of new staple crops provided a once-off benefit, however, this phase is now ending in PNG. This proceedings contains the 120 papers presented at the Papua New Guinea Food and Nutrition 2000 Conference held at the PNG University of Technology in Lae from 26-30 June 2000.

Download or read book The Potato Crop written by Hugo Campos and published by Springer Nature. This book was released on 2019-12-03 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY 4.0 license. This book provides a fresh, updated and science-based perspective on the current status and prospects of the diverse array of topics related to the potato, and was written by distinguished scientists with hands-on global experience in research aspects related to potato. The potato is the third most important global food crop in terms of consumption. Being the only vegetatively propagated species among the world’s main five staple crops creates both issues and opportunities for the potato: on the one hand, this constrains the speed of its geographic expansion and its options for international commercialization and distribution when compared with commodity crops such as maize, wheat or rice. On the other, it provides an effective insulation against speculation and unforeseen spikes in commodity prices, since the potato does not represent a good traded on global markets. These two factors highlight the underappreciated and underrated role of the potato as a dependable nutrition security crop, one that can mitigate turmoil in world food supply and demand and political instability in some developing countries. Increasingly, the global role of the potato has expanded from a profitable crop in developing countries to a crop providing income and nutrition security in developing ones. This book will appeal to academics and students of crop sciences, but also policy makers and other stakeholders involved in the potato and its contribution to humankind’s food security.
Download or read book Sweet Potato written by Ramesh C. Ray and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sweet potato (Ipomoea batatas L.), the seventh most important food crop after wheat, rice (paddy), maize, potato, barley and cassava, is a staple food in many developing countries of the tropics and sub-tropics, and also serves as animal feed and raw material for several food- and feed -based industries. This New World crop has high biological efficiency of converting solar energy into edible energy (152MJ/ha/day) in form of tuberous (storage) roots and could be the food for the ever growing human population in future. Asia leads in area (60.75%) and production (86.89%) of sweet potato in the world. Sweet potato was originally a herbaceous perennial but was domesticated as an annual and grows best in moderately warm climate and temperature of 21-26oC. It requires light textured soil with the optimum pH of 5.5 -6.5 for good growth of the crop. Current research has focused on development of high starch, high dry matter and coloured (ß-carotene and anthocyanin-rich) sweet potato varieties for industrial applications in addition to traditional usage as food and animal feed. Sweet potato storage roots are subjected to several forms of post harvest losses during harvest, transportation from farmers' field to market and in storage. These are due to mechanical injury, weight loss, sprouting, diseases and pests. The subject, post harvest aspects of sweet potato in food, feed and industries, is a topic of current interest.
Download or read book The Sweetpotato written by Gad Loebenstein and published by Springer Science & Business Media. This book was released on 2009-03-21 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last four decades of the twentieth century the use of sweetpotato was diversified beyond their classification as subsistence, food security, and famine-relief crop. In developing countries they serve both as human food and for feeding livestock. In Western countries they appeal to health conscious consumers because of their nutritional aspects. The sweetpotato is very high in nutritive value, and merits wider use on this account alone. The book has 2 parts. A general one giving up-to-date information on the history, botany, cultivars, genetic engineering, propagation, diseases and pests, nutritional data and marketing; and a second part presenting data on sweetpotato growing practices in different areas of the world. The information should be useful to researchers, practitioners and crop administrators in different countries.
