This book was released on 1977 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of these experiments were to determine the feasibility of saving seed from snap bean fields in the Willamette Valley that have been bypassed for canning and freezing, and to study the effects of different seed production methods on yield and quality of snap bean (Phaseolus vulgaris L.). Field experiments were conducted over a period of two years at the Oregon State University Vegetable Research Farm at Corvallis. The cultivars OSU 1604 and Asgrow 290 were used in these trials. Planting dates in 1975 were May 17, June 20, and July 3, and in 1976 were April 29, May 13, June 4, and June 22. Seeding rates of 165,000, 330,000 and 495,000 seeds/ha were used in both years. The quality of the harvested seed was assessed in terms of germination, seed size, protein content, seedling root length, seedling dry weight, halo blight infection, and field performance. The data indicate that technically it is feasible to produce snap bean seed in the Willamette Valley with yield and quality equal to those produced in traditional seed production areas. It is also suggested that high quality bean seed can be harvested from fields that have been bypassed for processing, provided they have been planted. The seed production methods tested affected nearly all aspects of the crop. Early plantings provided greater yields and delayed plantings decreased yields up to 62%. When planting was delayed until July 3, no seed was harvested because the crop did not mature before the fall rains. The three seeding rates tested did not affect total seed yield appreciably. Laboratory evaluations in 1975 showed no appreciable effects of planting date and seeding rate on seed quality. Field evaluation, however, showed that for Asgrow 290, seeds from the second planting had better stands and produced 20% more pods than seeds from the first planting. Likewise, seeds grown at low density produced 10% and 23% more pods than seeds grown at medium and high densities, respectively. OSU 1604 was not affected by cultural practices. In 1976, yield and seed quality of both cultivars were affected by planting date and seeding rate in the following ways: early plantings and low seeding rates produced greater yields, larger and heavier seeds and heavier seedlings. Late plantings and high seeding rates depressed yields, seed size and seedling weight. Protein content of seed was not affected by either of these variables.

This book was released on 2007-05-08 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants require nutrients in order to grow, develop and complete their life cycle. Mineral fertilizers, and hence the fertilizer industry, constitute one of the most imp- tant keys to the world food supplies. There is growing concern about the safety and quality of food. Carbon, hydrogen and oxygen, which, together with nitrogen, form the structural matter in plants, are freely available from air and water. Nitrogen, phosphorus and potassium, on the other hand, may not be present in quantities or forms sufficient to support plant growth. In this case, the absence of these nut- ents constitutes a limiting factor. The supply of nutrients to the plants should be balanced in order to maximise the efficiency of the individual nutrients so that these meet the needs of the particular crop and soil type. For example, it should be noted that EU-wide regulations are not designed to govern the specific details of mineral fertilizer use. Although plants receive a natural supply of nitrogen, phosphorus and potassium from organic matter and soil minerals, this is not usually sufficient to satisfy the demands of crop plants. The supply of nutrients must therefore be supplemented with fertilizers, both to meet the requirements of crops during periods of plant growth and to replenish soil reserves after the crop has been harvested. Pesticides are important in modern farming and will remain indispensable for the foreseeable future.

This book was released on 2011-01 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this research, Dr Mohamed Dawo shows how cross breeding common beans (Phaseolus vulgaris) of different growth habits (determinate and indeterminate) can result in producing genotypes capable of far out-yielding their parents. The research shows that indeterminate bean genotypes generally produce more seeds but smaller in size and the determinate ones produce bigger but fewer seeds. Key features of this research include: 1. Maize-bean intercropping using Nancis maize, a fodder plant and Carioca (a Mesoamerican Type III indeterminate Phaseolus bean) at different sowing dates. 2. The effect of planting density of maize and beans on final yield. 3. The yield and quality of fresh and ensiled plant material from intercropped maize (Zea mays) and common beans (Phaseolus vulgaris). 4. Below ground interactions of maize and beans in a fertilized and unfertilized area, showing how nodule number and the nodule mass per bean plant and mycorrhizal colonization in the maize roots is much higher in the unfertilized area than the fertilized one and why. 5. Analysing fresh and ensiled plant material for their nutritional value as animal feed for livestock.

Available in PDF, EPUB and Kindle. Book excerpt: The book "Quality and Production of Forage" is intended to keep readers updated on the developments occurring in this field. As it is apparent that livestock animals are important throughout the world because of the meat, milk and egg they produce, knowledge about the forages available to animals must also be considered for increased production, quality and efficiency. This book provides information that readers will find considerably invaluable about forage feeds, such as grass, legumes, and straw. The book is composed of ten papers, focusing on a wide range of research activities and topics that feature the following concepts of forage: the effect of conservation method on forage protein value; Microbial the composition and mycotoxin content in forage; genetic diversity of forages; timely sowing to maximize yield for both grain and biomass; ensiling treatments on forage quality; the qualitative characteristics of different accessions of new forage species; forage policy influencing feed costs; feeding forage on animal health; high-protein tropical forages as alternative sources for poultry; impact of forages in poultry diet and significance of forages in sustainable poultry production systems. This book will be an invaluable reference for students and professionals in agricultural science and grassland and animal husbandry researches.

This book was released on 2013-11-09 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: The common bean (Phaseolus vulgaris L. ) is the most important pulse crop in the world. It is an important source of calories, proteins, dietary fibers, minerals, and vitamins for millions of people in both developing and developed countries worldwide. It complements cereals and other carbohydrate-rich foods in providing near-perfect nutrition to people of all ages. Moreover, a regular intake ofbeans helps lower cholesterol and cancer risks. Despite the fact that per capita consumption of common bean in some developed countries (e. g. , the U. S. A. ) has been increasing over the last several years, in general, the average global per capita consumption is declining because production is unable to keep up with the population growth. Moreover, increasing demand for pesticide-free food products, concern for natural resources conservation, and the need to reduce production costs offer daunting challenges to the twenty-first century policy makers, bean growers, and researchers alike. High yielding, high quality bean cultivars that require less water, fertilizers, pesticides, and manual labor combined with integrated management of abiotic and biotic stresses will have to be developed. Eminent bean researchers were invited to contemplate these issues, prepare a state-of-the-art account on most relevant topics, and offer their insight into research directions into the twenty-first century. Four excellent books have been published covering various aspects ofthe common bean since 1980. These books are: I) Bean Production Problems nd in the Tropics (l SI ed. 1980, 2 ed. 1989), H. F. Schwartz & M. A.
