This book was released on 2013 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: In past years, grain protein concentration (GPC) has been highly variable from one location to the next. Many factors, environmental and genetic, contribute to the percent protein levels in the grain (Kramer, 1978). Along with increasing prices of inputs (land prices, machinery, fertilizer, and seed) producers continually need to adopt more efficient practices to ensure that GPC is at adequate levels so as to avoid potential dockage and/ or realize potential premiums. This study was conducted to determine the effect of droplet size and late-season nitrogen application on grain protein concentration. The effects of late season foliar N applications (post-anthesis) and droplet size on protein concentration were investigated on hard red winter wheat (Triticum aestivum L.) at three winter wheat sites in Oklahoma, Efaw (Stillwater), Lake Carl Blackwell, and Perkins. Foliar N was applied at two rates 11.2 and 22.4 kg ha−1 with three different droplet sizes per N rate; the 11.2 kg ha−1 N rate consisting of an adjuvant tank-mixed treatment and a non-adjuvant treatment. For most locations and years grain protein concentration was increased linearly with higher rates of foliar N applied. Use of the fine droplet size with a foliar N rate of 11.2 kg N ha−1 applied post anthesis and with the addition of an adjuvant resulted in the highest grain protein concentration.

This book was released on 1980 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: The response of cultivars of winter wheat to foliar applications of urea was examined for grain protein content, yield, and kernel hardness. The objectives of this study were to measure the effect of urea on these three traits in diverse environments and to explain how potential responses could occur by (1) determining potential uptake of N15 labelled urea from foliar application under greenhouse conditions using different cultivars, light duration, and soil fertility levels; (2) analyzing immature spike samples collected following foliar applications in the field during the flowering period; and (3) examining grain from primary and secondary tillers and from central and lateral florets within spikelets. Foliar applications significantly increased grain protein content over the control and standard topdressing treatment in most cultivars. For example, for a single cultivar at the Hyslop location in 1979-1980, protein percents of 11.18, 12.22, and 13.60 were obtained for the control, standard topdressing, and foliar urea treatments respectively. Generally, foliar applications of urea failed to increase grain yield over the control, and yield was significantly below the standard topdressing treatment. However, the combination of topdressed nitrogen with foliar sprays produced yields equal to topdressing alone while significantly increasing protein. Mean yields at the Wasco location of the topdressing treatment and the combination of topdressing and one foliar application were 4.05 and 4.04 T/ha, whereas the grain protein content averaged 9.34 and 10.45 percent respectively. Foliar applications of urea did not significantly alter kernel hardness. Significant cultivar x nitrogen treatment interactions were found for protein, yield, and hardness, and split applications of foliar nitrogen did not significantly change these results. A potential uptake of 29.2 to 61.4 percent of actual foltar applications was found with N15 labelled urea in a greenhouse experiment. A significant effect for light duration was observed with recovery values of 41.4 and 46.6 percent for 12 and 18 hour photo-periods respectively. The varieties Stephens and Centurk had a significant difference in uptake of 48.1 and 39.9 percent recovery respectively. Following urea sprays which were initially applied at the heading stage, nitrogen treatment differences were found within three weeks after anthesis. The ranking of treatments from immature spike analysis corresponded to grain protein analysis at harvest. Nitrogen treatments did not change the protein or hardness levels disproportionately for mature spikes in comparing grain from primary and secondary tillers or from central and lateral florets within the spikelets.

Available in PDF, EPUB and Kindle. Book excerpt: If one may recall nearly half a century ago, there wre small books, Methuen series publishing on special subjects like photosynthesis (C.P. Whittingham) and Plant Respiration (W.Stiles) in the 1950s and have been of great guidance for post-graduate studies in those years. Now great breakthrough have been made with the introduction of isotopes, modern tools and instruments which can project into the cell components and unravel the 'secrets' of plant life, with the results no one book could so completely cover a single topic like photosynthesis or respiration.

Download or read book Influence of Foliar Sulfur Chloride and Nitrogen on Winter Wheat Grain Yield and Total Nitrogen Triticum Aestivum L written by Sulochana Dhital and published by . This book was released on 2013 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimum use of nitrogen (N) is a key component in improving wheat grain yield and quality. The combined effect of other nutrients with N can have a positive impact on crop production. Using sulfur (S) and chloride (Cl) in wheat and other cereals has received increased attention in recent years. Foliar S and Cl can assist in optimizing wheat yield and total N, especially in sandy soils with low organic matter where deficiencies are expected. Winter wheat studies were conducted for 3 site-years at Lake Carl Blackwell (LCB) and Lahoma (LAH) in the fall of 2011 and 2012 to evaluate the effect of flag leaf applied foliar N, S and Cl on winter wheat grain yield and grain N. Two N rates, 10 and 20 kg N ha−1, as urea triazone (N-SURE, 28-0-0) and urea ammonium nitrate (UAN, 28-0-0) were foliar applied. Treatments included foliar application of gypsum (6 kg S ha−1) and calcium chloride at a rate of 10 kg Cl ha−1 applied with the help of CO2 backpack sprayer. Results showed total grain N increased with increasing preplant N rate at LCB and LAH. With increasing preplant N, a linear increase in yield was observed at LAH and a quadratic increase in yield at LCB. There was no response to foliar N, Cl and S at both locations. This study indicated that S and Cl fertilization did not increase yield and protein.

This book was released on 2001-12-03 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen in the Environment: Sources, Problems, and Management is the first volume to provide a holistic perspective and comprehensive treatment of nitrogen from field, to ecosystem, to treatment of urban and rural drinking water supplies, while also including a historical overview, human health impacts and policy considerations. It provides a worldwide perspective on nitrogen and agriculture. Nitrogen is one of the most critical elements required in agricultural systems for the production of crops for feed, food and fiber. The ever-increasing world population requires increasing use of nitrogen in agriculture to supply human needs for dietary protein. Worldwide demand for nitrogen will increase as a direct response to increasing population. Strategies and perspectives are considered to improve nitrogen-use efficiency. Issues of nitrogen in crop and human nutrition, and transport and transformations along the continuum from farm field to ground water, watersheds, streams, rivers, and coastal marine environments are discussed. Described are aerial transport of nitrogen from livestock and agricultural systems and the potential for deposition and impacts. The current status of nitrogen in the environment in selected terrestrial and coastal environments and crop and forest ecosystems and development of emerging technologies to minimize nitrogen impacts on the environment are addressed. The nitrogen cycle provides a framework for assessing broad scale or even global strategies to improve nitrogen use efficiency. Growing human populations are the driving force that requires increased nitrogen inputs. These increasing inputs into the food-production system directly result in increased livestock and human-excretory nitrogen contribution into the environment. The scope of this book is diverse, covering a range of topics and issues from furthering our understanding of nitrogen in the environment to policy considerations at both farm and national scales.

Available in PDF, EPUB and Kindle. Book excerpt: Central Asia is vulnerable to water scarcity because it is located in semiarid and arid vegetation zones and large parts of its economy depend on water for irrigation and energy. Climate-change scenarios predict temperature increases and a rising number of extreme weather events, which will exacerbate water shortages in the future. In addition, the population of Central Asia is growing more rapidly than the rate of food production which is resulting in food insecurity in many parts of the region too. This volume reports the deliberations of politicians, scientists and representatives of water management organizations from throughout Central Asia. Their contributions not only highlight areas of concern, but also propose numerous ideas for improving the long-term water- and food security in the region.
