The assessment of hazelnut mechanical harvesting productivity
(2017)Hazelnut cultivation represents a new opportunity for Calabrian mountainous and sloping areas (Southern Italy), where no alternative fruit crops, except forestry, could be settled. In this Region, hazelnut production ... -
Comparison of mechanical and electric drive of mulcher
(2017)The contribution is focused on comparison of mechanical and electric drive of mulcher with vertical axis of rotation by means of mathematical model. The mulcher has working width of 6 m and it is usually aggregated with ... -
Comparison of selected remote sensing sensors for crop yield variability estimation
(2017)Currently, spectral indices are very common tool how to describe various characteristics of vegetation. In fact, these are mathematical operations which are calculated using specific bands of electromagnetic spectrum. ... -
Comparison of tillage systems in terms of water infiltration into the soil during the autumn season
(2017)The soil belongs to the most valuable parts of the planet Earth. It is, endangered by water erosion, which causes huge destruction every year, or damage to farmland. More than half of the agricultural land in the Czech ... -
Comparison of tractor slip at three different driving wheels on grass
(2017)The paper deals with a possibility of tractor slip reduction on a grass and evaluates an use of two versions of special wheels. Both prototypes were developed at the Department of Transport and Handling of the Slovak ... -
Contribution of pumped hydro energy storage for more RES utilization on autonomous power systems
(2017)This paper addresses the performance issues of autonomous power systems under high renewable energy sources (RES) penetration. Renewable energy sources could be the main option for isolated power generation at remote ... -
Critical velocity of solid mineral fertilizers in a vertical upward airstream and repose angle
(2017)Critical velocity of mineral fertilizers in airstream is important not only at the application of fertilizers by spreaders but also at combine of fertilizing and sowing. The knowledge of angles of repose is important to ... -
Dry matter accumulation and nitrogen concentration in forage and grain maize in dryland areas under different soil amendments
(2017)Soil amendment plays significant role in improving soil fertility and increasing crop productivity in rain–fed agriculture. Understanding the grain yield associated with dry matter and N concentration is essential for ... -
Effect of controlled traffic farming on weed occurrence
(2017)Soil compaction caused by field traffic is one of the most important yield limiting factors. Moreover, published results report that soil over-compaction inhibits the uptake of plant nutrients and decreases their ability ... -
Effect of drill machine operating speed on quality of sowing and biomass yield
(2017)The paper is focused on the study and evaluation of quality of the seeding of seeds and its effect on the biomass yield. The aim was to evaluate the space arrangement of the seeds by using of polygon method on one field ... -
Effect of rake angle and cutting speed on energy demands of mulcher with vertical axis of rotation
(2017)The contribution deals with the reduction of agriculture energy demands. For maintenance and treatment of permanent grassland areas, areas left fallow and put to rest the mulching in combination with other workflows ... -
Effectiveness of simulation models on technical skills among surgeons. A critical review
(2017)Based on simulation models the surgeons can train technical skills and improve their functional status of musculoskeletal state. Work in good ergonomic position could reduce and prevent musculoskeletal disorders. The aim ... -
Energy balance of sunflower production
(2017)The aim of the present study was to make an energy analysis of sunflower crop in the Trakya Region of Turkey, to evaluate the potential for using it as bioenergy source. Actual data for the common cropping practices ... -
