In the paper we present the up-to-date mechanized production technology of cucumber production with regard to the transportation tasks. By the presentation of the performance and working hours data of machines necessary for production, we are emphasizing the significant volume of transport tasks in the production technology of cucumber. In the present cucumber production technology the working hour demand of machine operations and material handling is about 4,5 hours/tonne, besides a calculated average yield of about 12 t/ha. It can be stated on the basis of the results that the total working hour demand of the machines amounts 54 hours per hectare, which include the volume of transport and material handling tasks in value of 17 hours/ha. Special attention is to be paid to the machine operations like foil tunnel preparation, picking and planting which the most time demanding ones are representing about 9, 10 and 20 % of the total machine working hours. It is worth mentioning that time demand of transport and material handling takes the highest value, about 33 % of the total shift hours of production technology.
Computer age grants unlimited opportunities to design optimál agricultural machinery park. Considering this opportunity I have elaborated a decision supporting computing procedure based on a mathematical model This model helps us planing optimál machinery park to combine different land sizes, different plants to be produced and different power machines. At the same time the computing procedure is suitable for monitoring the external effects of plánt cultivation mechanisation.I have the pleasure to present in this paper the usage of this mathematical method.
In the 90's was a tremendous change undergone in the agricultural production in Hungary as a result of the economical processes in our area. The change in the structure of landed property, the free markét competition on the fíeld of in-and outputs created new possibilities and dangers for the individual farmer and for the economical companies, cooperatives as well.The aim of our investigations with the method of market-research at writing desk is to determine, what was the effect of the economical processes of the last decade in the agricultural mechanization, further if the nowadays investments provide a suffícient ground for assuring of the continuousness of the production.
ISO organization in early 90s defined an industry standard for the communication protocol among electronic devices of different manufacturers of agricultural machines. After that, all of the market actors recognised that this technology would be very important for agricultural electronics. The appearance of ISOBUS products in the market was in the mid-2000s. ISOBUS description could be found in ISO-11783. It is a very complex and large electronics protocol standard based on CAN and SAE-J1939 standards, extended for the Agricultural Industry. The standard consists of 14 different parts and more than thousands of specification pages. Through the standards and the related technical background, the production processes and the operations could be followed and monitored by the extensive Data Management. Farmers' and users legitimate needs and developing goal is to elaborate a decision support systems that follow-up the utilisation of the machines and ensure the quality of operations. For this purpose, it is essential to determine which technical, economical, technological parameters, detection, measurement, transmission, processing, and evaluation becomes necessary. In our work, we reviewed which mechanical characteristics, settings are monitored within the ISOBUS system by the major machine manufacturers. We developed the system of parameters and derived features that provide effective farm-, and land-management in case of attached equipment for spreading of input materials and tillage implements.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
