Book Influence of Fertilizer Treatment on the Response of Sugar Beet Yield to Moisture

Download or read book Influence of Fertilizer Treatment on the Response of Sugar Beet Yield to Moisture written by Samad Farzanfar and published by . This book was released on 1964 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Many factors that influence the growth and quality of sugar beets behave in one way under one set of conditions and in quite another under other conditions. Consequently, these factors should be considered together under a dynamic situation to find their interrelations and their influence on sugar beet yield. This study is a statistical analysis of the interaction of fertilizer and soil moisture potential with the yield of sugar beets grown in a crop rotation under different regimes of irrigation conducted over a period of seven years. The data are available for the years 1949 through 1956, from an intensive field experiment conducted under Western Regional Research Project W-29, entitled Soil-Water-Plant Relations under Irrigation. There is need of a complete statistical analysis of third order interaction for the whole cultural rotation. This third order interaction has been examined for the sugar beet crop grown in the seven years of the general cultural rotation, which includes peas, first year alfalfa, second year alfalfa, potatoes, and sugar beets.

Book Effect of Nitrogen Fertigation by Sprinkler Irrigation on Sugar Beet Crop Performance

Download or read book Effect of Nitrogen Fertigation by Sprinkler Irrigation on Sugar Beet Crop Performance written by Hamideh Nouri and published by . This book was released on 2009 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is crucial to make field management strategy by understanding of spatial and temporal variability of effective elements such as soil, water and plant properties. The impact of nitrogen fertigation by sprinkler irrigation would be a valuable step in support of environmental preservation and natural resources conservation. This research has focused on the spatial and temporal distribution of N fertigation by sprinkler irrigation and its effect on soil and plant properties to determine the relationship among fertigation distribution pattern and crop performance. This field variability study was carried out in the Fesaran village in east part of Esfahan city in Esfahan Province, Iran. Geostatistical sampling method was selected for an accurate interpolation by kriging to produce spatial and temporal variability maps. A total of 162 soil samples and 81 plant samples were collected and locations recorded using Differential Global Positioning System (DGPS). To describe the variability of soil and plant status, soil and plant nutrient response to the nitrogen fertilizer application by sprinklers was studied by analyzing 7 soil elements including N, P, K, CEC, OM, EC, and PH under two conditions, pre-treatment (before fertigation) and post-treatment (after fertigation). The sugar beet crop performance was based on 6 crop properties that include leaf N content, tuber moisture content, tuber sugar content, tuber weight, number of tubers in each square meter and yield. Variability maps were obtained using Geographical Information System (GIS) and Geostatistical statistics (GS+) software. Statistical analysis, geostatistical analysis and spatial analysis were employed to analyze the data. Data statistical analysis consist of descriptive analysis, T-Test (Pairwise two-tail), correlation (Pearson two-tail) and ANOVA (Duncan and SNK) and regression were derived from Statistical Package for the Social Sciences (SPSS) and Statistical Analysis System (SAS) software. The impact of N fertigation through sprinkler irrigation on spatial and temporal pattern of soil properties and spatial variability of sugar beet crop performance was studied through statistical analysis and visualization of spatial variability maps. The results show that the highest variability in available P (CV af = 89.7 %) and K (CV af =53.26 %) between selected soil properties. It could be related to non-uniform fertilization of potash and phosphate pre-plant that were applied manually. The least variability was seen in soil pH (CV af = 0.97 %) and OM (CV af =3.04 %). That is an evidence of very low variability of soil pH and OM through and across the study area. Low variability of soil N (CV bf = 12.44 %, CV af = 14.7 %) would be a key point to encourage farmers to replace fertigation by sprinkler irrigation instead of current methods. The highest variability of crop propertied belonged to tuber weight (CV=44.8 %) while the least variability was in tuber moisture content (CV=6.04 %) and tuber sugar content (CV=6.38 %) which points out the low variability if sugar and moisture content of tubers. Crop properties such as yield, tuber sugar content, tuber numbers, tuber moisture content and N leaf content have low variability (CV≤25%), except tuber weight with moderate variability. Spatial variability map displays concentration of the higher yield was seen in central area compared to least yield in the north west of the study area. Fewer tubers in the north and east of the study area compared to more tubers in the south and west. Interestingly, for those areas which have heavier tuber, the map shows fewer number if tubers. Plant performance analysis shows a negative significant correlation of leaf N content with sugar content of tuber at 95 % confidence. Tuber weight has a negative correlation to the number of tubers but positive correlation to the tuber moisture content. It indicates the higher moisture content causes heavier tuber but the grid which has more number of tubers has the lighter tubers. There is a negative correlation of tuber weight and number of tubers but positive significant correlation of number of tubers and sugar content. It indicates that more tubers with lighter weight have higher sugar content. Surprising result shows the negative correlation of leaf N content and sugar content.

Book Nitrogen in the Environment Sources Problems and Management

Download or read book Nitrogen in the Environment Sources Problems and Management written by R.F. Follett and published by Gulf Professional Publishing. 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.

Book Root Yields Sucrose and Glutamic Acid Content of Sugar Beets as Influenced by Soil Moisture Nitrogen Fertilization Variety and Harvest Date

Download or read book Root Yields Sucrose and Glutamic Acid Content of Sugar Beets as Influenced by Soil Moisture Nitrogen Fertilization Variety and Harvest Date written by Donald G. Woolley and published by . This book was released on 1956 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States produces about 1.8 million tons of sugar annually. Approximately 75 per cent of this production is derived from sugar beets. The importance of the sugar beet crop in national and world economy is justification for research effort as a means to more economical production. It is desirable that sugar beet processing be carried out in the most efficient manner. More effective utilization of the sugar beet and its by-products will add stability to the sugar beet industry. For the past 170 years, since Achard found that sugar could be used for human consumption and that pulp might be fed to cattle, sugar processors have made limited use of the non-sugar constituents of the sugar beet. These materials have been disposed of almost exclusively as livestock ration supplements. The non-sugar constituents have been largely responsible for failure to extract all of the sugar from the beet (13). As a result they have been viewed with suspicion by most sugar beet processors. However, recent development suggest that the utilization of sugar beet by-products will constitute a more important phase of the sugar beet industry in the future. At this critical period in the sugar beet industry, it is difficult to overemphasize the need for a better understanding of the chemical constituents of the sugar beet and the effects of various physiological factors upon them. One of the non-sugar constituents of the sugar beet which has recently received attention is glutamic acid. This has been brought about primarily by the discovery that the salt, monosodium glutamate, has an enhancing effect upon the flavor and palatability of many foods. Using the sugar beet as almost the exclusive source of glutamic acid, a new industry (utilizing over 100 tons of beet molasses daily) has developed to manufacture and market this food seasoner (28). Preliminary investigations at the Utah Experiment Station (14) showed that of all the chemical constituents determined, glutamic acid was the most variable. This agreed with earlier work in t
