Book Synopsis The Effect of Controlled Environmental Conditions on the Photothermal Requirement for Growth and Development, and on the Yield of Selkirk Wheat by : William James Rodger Boyd
Download or read book The Effect of Controlled Environmental Conditions on the Photothermal Requirement for Growth and Development, and on the Yield of Selkirk Wheat written by William James Rodger Boyd and published by . This book was released on 1961 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The duration of the phases in the life cycle of a particular plant genotype is considered to be under environmental control and attempts have been made to mathematically express these intervals in terms of the data representing the prevailing environment. One such expression, involving the temperature level and length of photoperiod, is known as the "Photothermal Index" which represents the photothermal requirement for a certain interval. In the course of this study the concept of photothermal constants has been thoroughly tested for the common wheat variety Selkirk (Triticum aestivum L.) under artificial growing conditions. Controlled variations in temperature, photoperiod, moisture and fertility levels were possible and as an adjunct the effect of these variations on yield characteristics (tillering, seed number, seed size and protein percentage) were obtained. It was found that the photothermal requirement is relatively constant for the periods emergence to heading and heading to maturity. However, certain exceptions were noted. The requirement increases with increasing fertility and when the temperature of the dark period is lower than that prevailing during the photoperiod. There is also an indication that for the period heading to maturity, low temperatures and low moisture levels reduce the requirement slightly. Tiller number was found to be greatest at temperatures of 54*F. and 60*F. but a higher proportion of spikes produced at 54*F. failed to set seed. Seed number was found to be favoured by a temperature of 60*F. while seed weight was highest at 54*F. Both characters are influenced by moisture levels. Protein percentage was unaffected by temperature but appeared to depend on the availability of soil nitrogen.
Book Synopsis Understanding Options for Agricultural Production by : G.Y. Tsuji
Download or read book Understanding Options for Agricultural Production written by G.Y. Tsuji and published by Springer Science & Business Media. 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.
Download or read book Rye written by Rolf H. J. Schlegel and published by CRC Press. This book was released on 2013-10-10 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Owing to its considerable winter hardiness, rye is a cereal that played a major role in the feeding of European populations throughout the Middle Ages. Recent data shows that rye is grown on about 5.4 million hectares, with a world production of approximately 13 million tons. While still an important bread food in many countries, rye produced for bread making has decreased or stagnated, whereas production is increasing for other market segments. Particularly, rye for feeding, ethanol processing, and biogas is promoted in Europe. The first comprehensive monograph on rye, Rye: Genetics, Breeding, and Cultivation gathers all the relevant and historic information from botany and genetics to utilization and sustainability of rye. The book covers taxonomy, morphology, and other botany-related aspects of rye. It describes its physiology, cytology, and genetics, including use for genetic improvement of other cereals. The author addresses various types of breeding such as population, hybrid, and molecular breeding. He also discusses rye cropping, including seeding techniques, fungal and viral diseases, and predators. The book examines the various uses for rye beyond bread making. This includes feeding, biomass and biogas production, ethanol production, and other important characteristics such as phytosterol content and antioxidant activity. It also explores the nutritional value of rye. Written by a leading expert in the field, this monograph compiles the most important facets of rye research, past and present.

Book Synopsis Crop Physiology Case Histories for Major Crops by : Victor Sadras
Download or read book Crop Physiology Case Histories for Major Crops written by Victor Sadras and published by Academic Press. This book was released on 2020-12-05 with total page 780 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crop Physiology: Case Histories of Major Crops updates the physiology of broad-acre crops with a focus on the genetic, environmental and management drivers of development, capture and efficiency in the use of radiation, water and nutrients, the formation of yield and aspects of quality. These physiological process are presented in a double context of challenges and solutions. The challenges to increase plant-based food, fodder, fiber and energy against the backdrop of population increase, climate change, dietary choices and declining public funding for research and development in agriculture are unprecedented and urgent. The proximal technological solutions to these challenges are genetic improvement and agronomy. Hence, the premise of the book is that crop physiology is most valuable when it engages meaningfully with breeding and agronomy. With contributions from 92 leading scientists from around the world, each chapter deals with a crop: maize, rice, wheat, barley, sorghum and oat; quinoa; soybean, field pea, chickpea, peanut, common bean, lentil, lupin and faba bean; sunflower and canola; potato, cassava, sugar beet and sugarcane; and cotton. A crop-based approach to crop physiology in a G x E x M context Captures the perspectives of global experts on 22 crops
