Abstract The Agro Techno Park (ATP) area was built with the aim of facilitating research, education, dissemination and acceleration transfer agricultural technology produced by government agencies, universities collaboration other multi actors. concept developed in Guguak is an integrated model that integrates agriculture animal husbandry, especially beef cattle food crops. purpose this paper t...
The objectives of this study were to explore farmers' intentions to implement foot and mouth disease (FMD) control in Ethiopia, and to identify perceptions about the disease and its control measures that influence these intentions using the Health Belief Model (HBM) framework. Data were collected using questionnaires from 293 farmers in three different production systems. The influence of perce...
Between 1950 and 1970, the introduction of new sugarcane varieties and improved crop husbandry in the South African sugar industry contributed to substantial gains in sucrose yield. However, in the subsequent three decades to date, sucrose yield has remained approximately constant, despite an increased rate of variety releases. This lack of progress is a phenomenon common to many sugar industri...
Many environmental problems of current concern are due to the high production and local accumulations of organic wastes that are too great for the basic degradation processes inherent in nature. With adequate application rates, animal manure constitutes a valuable resource as a soil fertilizer, as it provides a high content of macroand micronutrients for crop growth and represents a low-cost, e...
The present paper presents a non-technical overview of contemporary developments in food supply, as seen from the standpoint of economic adjustment. The historical concerns over availability and price of food have now passed in the UK, and agriculture is no longer dominantly driven by the supply-side forces of new farming technology and the stimulus of support policies. As a now demand-driven s...
Cultivation of sugarcane for bioethanol is increasing and the area under sugarcane is expanding. Much of the sugar for bioethanol comes from large plantations where it is grown with relatively high inputs. Sugarcane puts a high demands on the soil because of the use of heavy machinery and because large amounts of nutrients are removed with the harvest; biocides and inorganic fertilizers introdu...
Efficiency increase of resources through automation of agriculture requires more information about the production process, as well as process and machinery status. Sensors are necessary for monitoring the status and condition of production by recognizing the surrounding structures such as objects, field structures, natural or artificial markers, and obstacles. Currently, three dimensional (3-D)...
Hazelnut (Corylus avellana L.) is the one of the native and valuable shrub in Iran. Identification of the superior genotypes of hazelnut is the firs step for cultivation developing and breeding programs of this nut crop. In this research, had been studied phenological, morphological and pomological characters according to hazelnut’s descriptor for two years (2009-2010) on four populations of ha...
Rare earth elements (REEs), i.e. Sc, Y, La and the lanthanides, constitute an interesting group of 17 elements of extremely similar chemical properties that make their separation and analytical determination diffi cult. One of the lanthanides – promethium – has no stable isotope and does not occur naturally. REEs are elements of steadily growing importance in science and in various branches of ...
Two different patterns in input–output relations can be distinguished in agricultural production. For the first, yields are obtained at zero rates of certain external inputs, such as in wheat growing, or dairying based on grazing. For a second type of input–output relation, inputs are required before any yield can be obtained, such as in irrigation schemes in desert areas, or industrial product...
