The measured results were evaluated by the multiple regression dependence method. They show that in the case of both the conventional as well as the enriched cages a statistically significant dependence exists between the eggshell deflection (dependent variable) and thickness, or the force needed for the eggshell destruction (independent variable). The respective P values are given in brackets (0.002 < 0.05; 0.03 < 0.05; 1.16 × 10-10 < 0.05; 8.31 × 10-4 < 0.05); in the case of the conventional cage and enriched cage also a statistically significant dependence existed (3.81 × 10-91 < 0.05; 3.86 × 10-81; 1.27 × 10-97 < 0.05; 3.46 × 10-57 < 0.05) between the shell weight (dependent variable) and shell thickness, or egg weight (independent variable); in the conventional cage, statistical dependence also occurred between the eggshell weight and egg shape index, (1.07 × 10-6 < 0.05), in the enriched cage this was on the verge of statistical significance (0.062 > 0.05); if in the conventional cage the eggshell thickness was increased by 1 mm, the shell deflection decreased by 0.08 mm,and if the force necessary for the eggshell destruction was increased by 1 N, the shell deflection decreased by 0.0003 mm; if in the conventional cage the shell thickness was increased by 1 mm, the shell weight increasee by 15.509 g and if the egg weight was increased by 1 g, the shell weight increased by 0.061 g. Our work brings further knowledge concerning the monitored characteristics and their mutual relations.

The surface area of the field was 22 ha. The basic soil hydrological coefficients were measured in 19 monitoring points, specifically the field capacity and the wilting point. The field capacity ranged between 28.83% and 32.11% by vol., and the wilting point was in the interval between 8.40% and 12.40% by vol. At the conclusion, the soil moisture as a factor decisive for determining the irrigation rate was measured in these monitoring points. The irrigation rate ranged from 0 to 40 mm for the specific date of the soil moisture determination. During the whole growing season, five irrigation rates were applied according to the principles of precision irrigation. As compared to conventional water application, precision irrigation contributed to water saving in the amount of 478.56 m3/ha. The electric power saving reached 249.68 kWh/ha. The cost saving was characterised by the value of 9.1 EUR/ha and this represented 23.8%. The results have shown that precision irrigation is a fully effective system of precision farming, although the procurement and implementation of new technology and software requires at first a significant financial cost. There is also an increased need for the education and skills of the operating staff.

It is necessary to make use of the most exact method with respect to the computing power for a majority of microprocessors, because errors are integrated within them due to the algorithm. In our contribution, trapezoidal rule and Romberg's method of numerical integration are compared in the velocity calculation algorithm of the strapdown inertial navigation. The sample frequency of acceleration and angular velocity measurement was 816.6599 Hz. Inertial navigation velocity was compared with precise incremental encoder data. Trapezoidal method velocity error in this example was 1.23 × 10-3 m/s in the fifteenth-second measurement. Romberg's method velocity error was 0.16 × 10-3 m/s for the same input data.

The measurements were done on a test bench in the laboratory of the Agroscope Reckenholz-Tänikon Research Station ART, Ettenhausen, Switzerland during February 2010. The goal of this paper was to evaluate the operating parameters of the two models of tractors by using classical diesel oil and biofuel, as well as to evaluate the emission (greenhouse gases, dangerous exhaust gases and carcinogens), to make statistical analysis of the results and the conclusion about the samples used and the impact on engine parameters, environment and human health. From the results achieved, it is possible to state the following facts. In each way, the emissions of rape seed methylester (RME) and diesel are equivalent. The values of CO and HC and also particles are lower for RME. But NOx values are lower for diesel oil. It is liquid that the newer engine of Hürlimann XB Max 100 decreases emission of CO, HC and NOx significantly.

The first one was mineral oil type UTTO which is commonly used in the transmission and hydraulic systems of agricultural tractors. The second one tested was biodegradable hydraulic fluid type ERTTO which could replace the toxic mineral oil. Both fluids were tested under the same test conditions using a special test device. The selected parameters of the hydrostatic pump were evaluated. The tests were evaluated according to the parameters describing the technical state of the hydrostatic pump as follows: flow efficiency, decrease of flow efficiency and cleanliness level of the fluid tested. This additional measurement verifies the test results. On the basis of the results achieved, we can state that the biodegradable hydraulic fluid exerts no harmful influence on the technical state of the hydrostatic pump. Therefore, the biodegradable fluid tested can be applied to the agricultural tractor. Has been demonstrated that the selected parameters are suitable for the evaluation of hydraulic fluid during its working performance. Therefore, these parameters will be used in the next examination of the fluid under operational conditions of an agricultural tractor.
