Book Description
Excerpt from Effect of Storage, Bulb Size, Spacing, and Time of Planting on Production of Onion Seed The best temperature at which to store mother bulbs of a highly non bolting strain of Ebenezer was about 535 F. Plants from bulbs stored at this temperature bloomed and ripened their seed earlier, produced more seed stems and yielded more seed per acre than plants from mother bulbs stored at higher or lower temperatures. In a comparison of eight different Sizes of mother bulbs of the Yellow Globe Danvers variety ranging in weight from about 15 to 90 grams, there was found to be an increase in number of seed heads per plant, in seed yield per plant, and in seed yield per acre with each increase in Size of bulb. In spacing tests with the Yellow Globe Danvers variety, bulbs were set 3, 4, 6, 8, and 12 inches apart in a row. A significant increase in seed yield per plant was secured with each increase in spacing but a decrease in yield of seed per acre. When bulbs of Yellow Globe Danvers were planted at different dates throughout the winter there was a delay in time of seed maturity of the late-planted bulbs; and, accompanying this, a decrease in yield of seed.

Book Description
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 Description
Revised and expanded throughout, this latest edition of the bestselling Seeds Handbook: Biology, Production, Processing, and Storage includes valuable information on all areas of seed biology, production, and processing. The author, one of the most respected and prolific scientists in the field, identifies current developments in seed testing and certification, storage, transportation, and distribution. Tracking the evolution and advancement of seed industries and technologies, he fully covers the development and supply of high-quality seeds for every key agronomic and horticulture crop. Contains methods to enhance the genetic and physiological characteristics of more than 80 major and minor crops With an abundance of current research and additional figures and illustrations, this edition of the Seeds Handbook offers chapters on modern biotechnological issues such as the production of synthetic seeds, loss-reduction biotechnologies, and new strategies in the seed production industry. It provides in-depth information on burgeoning areas of seed science including tissue culture and cellular totipotency, induction and regeneration protocols, development and maturation, hormone requirements, drying and storage of somatic embryos, protective encapsulation, and crop applications. With an eye to the future, it looks at challenges in the provision and enhancement of seeds for crop plants, practical methods of seed production and micropropagation, genetically modified seeds, and world food security.

Book Description
Growing for 100 - the complete year-round guide for the small-scale market grower. Across North America, an agricultural renaissance is unfolding. A growing number of market gardeners are emerging to feed our appetite for organic, regional produce. But most of the available resources on food production are aimed at the backyard or hobby gardener who wants to supplement their family's diet with a few homegrown fruits and vegetables. Targeted at serious growers in every climate zone, Sustainable Market Farming is a comprehensive manual for small-scale farmers raising organic crops sustainably on a few acres. Informed by the author's extensive experience growing a wide variety of fresh, organic vegetables and fruit to feed the approximately one hundred members of Twin Oaks Community in central Virginia, this practical guide provides: Detailed profiles of a full range of crops, addressing sowing, cultivation, rotation, succession, common pests and diseases, and harvest and storage Information about new, efficient techniques, season extension, and disease resistant varieties Farm-specific business skills to help ensure a successful, profitable enterprise Whether you are a beginning market grower or an established enterprise seeking to improve your skills, Sustainable Market Farming is an invaluable resource and a timely book for the maturing local agriculture movement.
