The aim of the research was to create a model for prediction of tuber dry matter on the basis of underwater weight of tubers (UWW), with the use of neural modelling methods. In order to achieve the aim of the study, data from the years 2011-2017 were collected from the production fields of an individual farm located at the border of Pomeranian and West Pomeranian Voivodeships in Słupski and Sławieński...
The aim of the research was to indicate the possibility of using digestate which was obtained in the process of biogas production and the analysis of the effects of the aggregation process using rolling. The characteristics of fertilizers were determined based on the analysis of the basic properties of post-fermentation pulp such as: dry matter, organic matter, pH, C: N ratio, content of macroelements...
Wheat, corn and rapeseed straw can be used as a raw material for the production of biofuels used to generate heat energy. Due to the growing interest in renewable fuels, including straw, it is reasonable to test the energy suitability of these fuels. The aim of the study was to compare the combustion heat and calorific value of particular straw species. The most important parameters enabling comparison...
The aim of the work was to produce three independent models for prediction and simulation of winter wheat yield, which were marked in the following way: ReWW15_04, ReWW31_05 and ReWW30_06. The produced models enable to make yield forecasts for April 15, May 31 and June 30, directly before harvest in the current agrotechnical season. For the construction of prediction models the Multiple Linear Regression...
The aim of the work is to create a model for prediction and simulation of winter rapeseed yield. The model made it possible to perform a yield forecast on 30 June, directly before harvest in the current agrotechnical season. The prediction model was built using the multiple regression method (MLR). The model was based on meteorological data (air temperature and precipitation) and information about...
The subject of the work concerns the design of a hybrid solar system to maintain mesophilic conditions in the process of anaerobic biomass decomposition. The main purpose of the work was to design a hybrid heating installation for a biomass utilizer. It was assumed to simulate the use of three energy sources: photovoltaic panels, solar collector and heat from biogas combustion. It was assumed that...
The aim of the work was to design and implement an application with using Augmented Reality technology for supporting dairy cattle monitoring. This article presents the developed application and conclusions concerning the usage of Augmented Reality generally in agriculture.
The aim of the following work is to indicate factors which significantly affect the emergence of selected soybean varieties after application of natural herbal extracts based on - Levisticum officinale L., Ribes nigrum L., Matricaria chamomilla L., as wet seed treatments using two methods of treatment. The research material included seeds treated for 24 hours in macerats, decoctions and infusions...
The search for alternative fuels is becoming increasingly common due to exhausting conventional energy sources. One of the solutions is to manage waste from agricultural and food production for energy purposes. The aim of the study was to compare possible energy gains from the use of apple pomace as a fuel in two variants. The first option consisted in converting waste into solid fuel for combustion,...
The paper presents the application of a high precision positioning system ASG-EUPOS and its service NAWGEO for agricultural machines positioning. A measurement set was mounted on a cereal combine harvester and consisted of a GNSS antenna and receiver with a GSM modem for RTK corrections transfer. The positioning system was validated in a field during the 2011 harvest period in selected farms in southern...
The purpose of the following work is to review the methods used in predicting plant yields, with particular emphasis on potato production. The article refers to the histological methods of estimating plant yields and prevailing trends: groundbased remote sensing, which is often associated with regression calculus, multiple regression, artificial intelligence and image analysis. There are also two...
The article presents changes in the total annual emission of limited toxic compounds released into the atmosphere together with exhaust gases from farming machinery used in Poland between 2011 and 2013. The calculations were based on the amounts of the excise tax refund for ‘farming’ fuel, which were expended from the budget during the years under study. The methodology of calculations presented by...
The aim of the study was to attempt to build and validate the neural model controlling the qualitative selection of the stream of grain mass as early as the stage of combine harvesting of winter wheat. The model uses the highest possible number of data describing locally changeable environmental conditions such as: protein content, moisture and yield of wheat grain, soil abundance in basic nutrients...
W artykule przedstawiono zaprojektowany i wytworzony internetowy system ekspertowy wspomagający doradztwo rolnicze w zakresie ochrony plantacji buraka cukrowego. Zadaniem systemu jest udostępnienie informacji dotyczących szkodników, chorób oraz innych czynników powodujących znaczące straty w plonie bądź powodujących spadek jego jakości. Moduł doradczy zaimplementowany w systemie pomaga w ocenie występującego...
Celem pracy było przedstawienie możliwości zastosowania nowoczesnej pod względem technologicznym, telefonii internetowej popularnie nazywanej VoIP lub telefonia IP. Zaprezentowano metody kompresji dźwięku oraz możliwości zastosowania w oparciu o aktualnie wykorzystywany protokół SIP. Przedstawiono także implementację omawianej technologii w małym przedsiębiorstwie rolniczym. Upowszechnienie tej metody...
Badania polowe, w odróżnieniu od laboratoryjnych, wymagają znacznie większego zaangażowania czasu, nakładów pracy i kosztów dla uzyskania odpowiedniej ilości danych pomiarowych. Jednocześnie badania polowe są niezbędnym elementem do weryfikacji wyników z doświadczeń laboratoryjnych w warunkach rzeczywistych. Stąd bardzo cenne są wszelkie techniki pozwalające na prowadzenie badań terenowych w sposób...
