This book was released on 1990 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: High levels of chlorophyll in harvested canola seed cause an increase in processing costs, lower returns for producers and poorer quality end products. The effects of genotype, environment and agronomic practices on seed chlorophyll levels were investigated in this study. When canola seed was frozen for up to one month, either in the pods or after removal, no significant reduction in chlorophyll was observed. Results from a swathing study indicate that seeds from the side branches contained 1.5 to 2 times as much chlorophyll as seeds from the main stems. Seed that was dried rapidly contained 1.5 to 6 times as much chlorophyll as seed allowed to mature in swaths in the field. When seeds from each treatment in the swathing study were subdivided according to size, the smallest seeds were found to contain the most chlorophyll. Seed from the treatments with the highest chlorophyll levels also contained the greatest amount of small seed. Chlorophyll degradation rates were investigated in four cultivars of Brassica napus as the seed ripened. No significant differences in the rate of chlorophyll breakdown were found between the different cultivars tested. Cultivars that require longer growing seasons to reach maturity were found to initiate seed chlorophyll degradation later in the growing season, increasing the chances that high levels will remain when the seed is harvested. The environment did affect the rate of chlorophyll degradation, as slower breakdown rates did occur in later sown plots. This was assumed to be due to the lower daily mean temperatures which occured later in the growing season. A number of cultivars of both B. napus and B. campestris grown at sites throughout Manitoba were measured for seed chlorophyll levels at harvest. No significant differences were found among different cultivars of B. campestris but the final chlorophyll levels of B. napus seed were extremely variable, both among triazine tolerant cultivars and those without triazine resistance. The environment also affected the seed chlorophyll level and there was a significant genotype by environment interaction. Seed samples of a number of cultivars taken from high chlorophyll sites were subdivided according to size and the smallest seeds were found to contain the most chlorophyll. The relationship between the percentage of small seed in any sample and the chlorophyll level was less defined in the "Agroman" material than in the swathing study.

After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Canola is a cool-season, oilseed crop grown throughout Europe, Canada, and the Northern Great Plains region of the United States. The expansion of canola production into new growing regions, such as the Southern Plains region, has resulted in new production challenges. The Southern Plains region cultivates canola as a winter annual compared to a spring annual for the Northern Great Plains and Canada. Given the difference in climate and weed spectrum, region-specific weed management systems need to be developed. Agronomic practices can affect seed oil content, protein content, and fatty acid composition, however the effect of herbicides on these and other characteristic of canola are unknown. Therefore, experiments were conducted in 2010 and 2011 to evaluate a broad spectrum of herbicides for potential use in South Texas canola production with respect to crop injury, effects on canola seed oil content, fatty acid composition, weed control, biomass yield, and forage quality. Visual crop injury at 42 DAE was unacceptable for saflufenacil at both 0.12 and 0.06 kg ai ha-1 and ethalfluralin at 1.05 kg ai ha-1. Trifluralin at 1.12 and 0.56 kg ai ha-1, S-metolachlor at 2.14 and 1.07 kg ai ha-1, pyroxasulfone at 0.24 and 0.12 kg ai ha-1, and pendimethalin at 0.8 kg ai ha-1 had lowest visual injury of all treatments. Fluroxypyr applied EPOST caused severe injury at both 0.21 and 0.11 kg ae ha-1. All other EPOST treatments did not cause any visible injury. Seed oil content was not affected by the herbicides evaluated. Fatty acid composition, specifically stearic acid, oleic acid, linolenic acid, and oleic to linolenic acid ratio, was affected by herbicide treatments. This research found that protoporphyrinogen oxidase (PPG oxidase) inhibitor herbicides, such as carfentrazone-ethyl and saflufenacil, negatively affect canola oil quality. Biomass yield was improved for all herbicide treatments except pendimethalin PRE when compared to the untreated plots. Crude protein content of canola forage was not affected by herbicide treatment. Digestible dry matter appeared to be reduced by treatments that included an EPOST application of sethoxydim. The research shows that pendimethalin and S-metolachlor may be suitable for canola production in South Texas based on low crop injury and effective weed control. Neither pendimethalin nor S-metolachlor is currently labeled for use in canola. The herbicides trifluralin, ethalfluralin, quizalofop P-ethyl, ethametsulfuron-methyl, sethoxydim, glyphosate, clethodim, and clopyralid are currently labeled for use in canola and were confirmed suitable for canola production in South Texas. Carfentrazone-ethyl is currently labeled for use in canola but the effects on oil quality should be considered.

Book excerpt: Chlorophyll is normally removed from canola seeds during the natural maturing process and usually has disappeared completely by the time the canola is mature. Chlorophyll retention can be caused by improper ripening, frost, disease, or drought. This project was conducted to examine methods of reducing chlorophyll in harvested canola. Two batches of canola were harvested and subjected to various in-bin treatments. Chlorophyll, moisture content, and other factors were monitored during the tests.

Book excerpt: In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental, community, labor, and animal welfare standards in agriculture. Toward Sustainable Agricultural Systems in the 21st Century assesses the scientific evidence for the strengths and weaknesses of different production, marketing, and policy approaches for improving and reducing the costs and unintended consequences of agricultural production. It discusses the principles underlying farming systems and practices that could improve the sustainability. It also explores how those lessons learned could be applied to agriculture in different regional and international settings, with an emphasis on sub-Saharan Africa. By focusing on a systems approach to improving the sustainability of U.S. agriculture, this book can have a profound impact on the development and implementation of sustainable farming systems. Toward Sustainable Agricultural Systems in the 21st Century serves as a valuable resource for policy makers, farmers, experts in food production and agribusiness, and federal regulatory agencies.
