Book excerpt: Research Paper (postgraduate) from the year 2018 in the subject Agrarian Studies, grade: Degree of MASTER, Jimma University College of Agriculture and Veterinary Medicine (Jimma University), course: Horticulture, language: English, abstract: Haphazard and inappropriate plant spacing and poor soil fertility management practices are among the major factors constraining onion production in the Central Zone of Tigray. Therefore, a field experiment was conducted in Axum district from October to March 2014 to assess the influence of intra-row spacing (2.5, 5, 7.5, 10 and 12.5 cm) and nitrogen rate (0, 41, 82 and 123 kg N ha-1) on growth, bulb yield, and quality of onion. The experiment was laid out in a randomized complete block design (RCBD) of factorial arrangement with three replications. The main effects of nitrogen rate and intra-row spacing influenced only the plant height and stand count significantly (P
Book Synopsis Onions and Other Vegetable Alliums by : James L. Brewster
Download or read book Onions and Other Vegetable Alliums written by James L. Brewster and published by CABI. This book was released on 2008 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fully revised, expanded and updated edition of the successful text, Onions and Other Vegetable Alliums, relates the production and utilization of these familiar and important vegetable crops to the many aspects of plant science underpinning their production and storage technologies. Chapters cover species and crop types, plant structure, genetics and breeding, physiology of growth and development as well as pests and diseases, production agronomy, storage after harvest and the biochemistry of flavour, storage carbohydrates and colour and how this relates to nutritional and health benefits. From this wide perspective it is possible to see many examples where underlying scientific knowledge illuminates, explains and can improve agronomic practice. The reader will get an insight into how molecular methods are revolutionizing the study of taxonomy, genetics, pathology and physiology and how these methods are being applied in the breeding of improved crops.
Book Synopsis Vegetable Production and Practices by : Gregory E Welbaum
Download or read book Vegetable Production and Practices written by Gregory E Welbaum and published by CABI. This book was released on 2015-01-30 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Successful vegetable production in a modern competitive market requires an understanding of many more factors than the biology of crops and the production techniques involved. This major new textbook brings the science and practice of vegetable production right up to date by addressing modern culture techniques and the recent challenges of consumer demand facing producers today. It introduces vegetable production from the perspective of producing high quality produce that satisfies the needs of the modern consumer. Beginning with the basics of how vegetables are grown using high and low input methods, including organic and sustainable production techniques, the book goes on to introduce and discuss many topics covered less comprehensively in older texts, including Good Agricultural Practices to improve quality, reduce biological contamination and secure food safety; water management; cropping systems; plasticulture; protected culture and mineral nutrition. Vegetable Production and Practices also introduces the use of molecular biology for genetic improvement of crops. Issues specific to individual vegetable crops are addressed by family, including their diseases, harvesting, quality attributes and other issues of increasing importance to consumers, including the role of vegetables in human health. Professor Gregory E. Welbaum has a long history of teaching successful courses in horticulture at Virginia Tech and other universities in the US and worldwide. Vegetable Production Practices has been specifically designed to accompany courses in vegetable crop production, so is ideally suited to inspire students in crop and horticultural sciences, as well as provide a useful reference for experienced practitioners.

Book Synopsis The Effect of Bulb Size and Plant Density on Yield and Quality of Onion (Allium cepa var cepa L) Seed, at Ziway, Central Ethiopia by : Zerihun Zena
Download or read book The Effect of Bulb Size and Plant Density on Yield and Quality of Onion (Allium cepa var cepa L) Seed, at Ziway, Central Ethiopia written by Zerihun Zena and published by GRIN Verlag. This book was released on 2013-01-29 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2008 in the subject Agrarian Studies, grade: 3.17, University of Hawassa (Awassa College of Agriculture), course: Horticulture, language: English, abstract: Plant density and bulb size trial was conducted at Ziway in order to identify the optimum agronomic management practices, which contribute to maximized seed production in onion crop both in terms of quantity and quality. The experiment was laid down in split plot design with three replications, keeping plant density as main plot factor and bulb size as sub plot factor. The effects were studied by collecting data on bulb sprouting and plant performance, yield components, seed yield and seed quality parameters. Analyses of variance, mean comparison using least significant difference, correlation analysis were made using SAS computer software. Plant density significantly influenced bulb sprouting, umbel size, seed yield per 100m2and germination percentage. The largest umbel size (4.9cm) was obtained from low plant density; where as the smallest (4.4cm) from high plant density. Maximum seed yield per 100m2(1,163,446 seeds) was collected from high density while low density yielded only 416,240 seeds per 100m2. However the quality of seed in terms of germination was highest for seeds obtained from low density. The influence of bulb size was significant on plant height, number of flower stalks per plant, number seeded florets per umbel, seed per plant, seed per 100m2, seed yield (qt/ha) thousand seed weight. Plants grown from large bulbs produced plants with best height (72.3cm), highest number of flower stalks (8.5), seeded florets per umbel (368.7), seed per plant (1,539), seeds per 100m2(994,434) and seed yield in qt/ha (10.42). Seeds with best thousand seed weight (4.2g) were obtained from medium bulbs and small bulbs performed least in all aspects. Correlation analysis was made to study the relationship among plant growth, yield component, seed yield and quality parameters and their respective influence on yield and yield quality. Positive correlation existed between plant height and umbel size with seeded florets per umbel; flower stalk per plant, plant height, umbel size, seeded florets per umbel and number of seeds per floret with seed yield per plant, which was highly correlated with seed yield (qt/ha). However, further studies ought to be conducted in order to understand clearly, why bulb size and plant density interaction effect was insignificant Key words: Plant density, bulb size, bulb sprouting, plant performance, seed yield and seed quality

Book Synopsis Plant Genetic Resources of Ethiopia by : Jan Engels
Download or read book Plant Genetic Resources of Ethiopia written by Jan Engels and published by Cambridge University Press. This book was released on 1991-03-21 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the world centers of crop evolution and origin, Ethiopia has long been recognized as an important area of diversity for several major and various minor crops. Based on an international conference held in Addis Ababa, this book describes how plant genetic diversity in Ethiopia is of vital importance in breeding new varieties of crops with desirable characteristics, such as increased resistance to pests and diseases and greater adaptation to heat and drought. The three main sections in the book consider the Ethiopian center of diversity, germ plasm or genetic material collection and conservation in Ethiopia, and the evaluation and utilization of Ethiopian genetic resources. A broad range of food and feed crops and plants of medicinal and industrial importance are discussed, both at a national and international level. A brief account of conservation strategies and gene bank problems unique to Ethiopia is also given. The importance of Ethiopia's plant genetic resources to world agriculture has been demonstrated on more than one occasion. Plant breeders, geneticists, and botanists throughout the world will, therefore, find this unique book a valuable source of information and an essential reference work.
