Grain crops, industrial and fodder crops occupy determinant proportion of the sown area (in 2004 this figure was 88,4%). Cultivation typically produces mass products, with an almost entirely mechanised production structure. This fact was neither changed by the significant transformation of ownership and farming forms, and the headway of individual farming using smaller land sizes. It has a disadvantageous consequence that the adjusting of production to the site conditions of production and to the dimension of farming was not started in a perceptable degree. The production of mechanisable products regarded as big farm products — cereals, maize, rape, sunflower — are preferred both by farming organisations, and individual producers. The former production structure has been conserved owing to the shortage of capital, the lack of expertise of different fields, and the absence of market orientation. It is a certain furtherance that the role of individual farms is gradually becoming stronger in the production of the so-called “small products”. In the examined period the general decrease and occasionally the salient fluctuation of average yields can be observed (in recent years it increased). The annual fluctuation of yield levels and their change during the examined period was influenced not only by regional differences and the effect of weather, but also the shortcomings in agricultural technical equipment.
