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 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...
Soybean (Glycine max L.) is one of the most popular crop species in the world, which supplies raw material for the production of commercial fodder in Poland, as well as throughout the European Union. Unfortunately, climatic conditions and available varieties of soybeans and few preparations registered in plant protection are the main reason for low production in EU countries. The subject of the following...
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...
