This book was released on 1973 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: A better understanding of weed-soybean (Glycine max (L.) Merr.) interference is necessary before accurate damage thresholds can be determined for weeds growing in soybeans. The objective of this study was to use area of influence methodology to evaluate weed-soybean interference. This objective was accomplished by: (a) monitoring the length and area of soybean row influenced by one common cocklebur (Xanthium strumarium L.) and one sicklepod (Cassia obtusifolia L.) plant throughout a growing season and (b) monitoring soybean interference effects on the vegetative growth of these two weed species. Results from this two-year field study indicate that in both years, soybeans' first measurable effect on common cocklebur and sicklepod vegetative dvelopment occurred betweeen the sixth and eighth week after palnting, and soybean continued to strongly interfere with common cocklebur and sicklepod development over the course of the growing season. However, common cocklebur was less affected than sicklepod by soybean interference. Common cocklebur's first measurable effects on soybean vegetative development occurred 10 weeks after planting in 1984 and 12 weeks after planting in 1985. Sicklepod's first measurable effect on soybean growth occurred 12 weeks after planting in both years. Weed interference effects were greatest on soybean plants closest to the weed and decreased linearly with increasing distance from the weed. At seed harvest, the number of soyban pods per plant was the primary yield component influenced (...).

This book was released on 2013-03-14 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first premise of this book is that farmers need access to options for improving their situation. In agricultural terms, these options might be manage ment alternatives or different crops to grow, that can stabilize or increase household income, that reduce soil degradation and dependence on off-farm inputs, or that exploit local market opportunities. Farmers need a facilitating environment, in which affordable credit is available if needed, in which policies are conducive to judicious management of natural resources, and in which costs and prices of production are stable. Another key ingredient of this facilitating environment is information: an understanding of which options are viable, how these operate at the farm level, and what their impact may be on the things that farmers perceive as being important. The second premise is that systems analysis and simulation have an impor tant role to play in fostering this understanding of options, traditional field experimentation being time-consuming and costly. This book summarizes the activities of the International Benchmark Sites Network for Agrotechnology Transfer (IBSNAT) project, an international initiative funded by the United States Agency for International Development (USAID). IBSNAT was an attempt to demonstrate the effectiveness of understanding options through systems analysis and simulation for the ultimate benefit of farm households in the tropics and subtropics. The idea for the book was first suggested at one of the last IBSNAT group meetings held at the University of Hawaii in 1993.

Book excerpt: Worldwide, soybean seed proteins represent a major source of amino acids for human and animal nutrition. Soybean seeds are an important and economical source of protein in the diet of many developed and developing countries. Soy is a complete protein and soyfoods are rich in vitamins and minerals.Soybean protein provides all the essential amino acids in the amounts needed for human health. Recent research suggests that soy may also lower risk of prostate, colon and breast cancers as well as osteoporosis and other bone health problems and alleviate hot flashes associated with menopause. This volume is expected to be useful for student, researchers and public who are interested in soybean.
