Es wird ein Vergleich von Wert der Bruttowertschöpfung und Produktivität in der Landwirtschaft, zwischen den Ländern, die zu EU gehören, gemacht. Es wird bestätigt, dass Produktivitätsanalyse der Produktionsfaktorennutzung und ihren Aufwände zum Nachteil der polnischen Landwirtschaft fällt.
The aim of the paper was to analyse the relation of milk yield per cow with a set of production factors on sample data from six dairy farms located in the central region of Poland. The farms, which were the subject of the study, carried out an intensive production, achieving milk yield over the national average. The research showed an increase in milk yield with increasing number of cows in the herd, which, in practice, can lead to increased loads in milking installations in farms keeping more cows.
The aim of the paper is an assessment of changes in production factors productivity in commercial farms in 2012 in comparison to 2004. An analysis concerns the fl exibility of relations among production factors like: arable lands areas in hectares, human labor input in man-hours, total cost in Polish zloty in 2004 and 2012 and the effects resulted from using above mentioned factors expressed in production value. It allowed to make an assessment of changes in rural farms’ economic effectiveness within eight years after Poland’s accession to the European Union. In surveyed period average labor effectiveness increased of 86.5%, and land effectiveness of 29.7%. Average capital productivity decreased just like labor and land margin productivity.
The paper includes the results of measurements of timber logs sorting by a modern, equipped with the newest measurement and steering systems line for automatic pretreatment of timber materials. The examined research was made in one of sawmills of Pomeranian Voivodeship.
