Keywords: energy-saving; combin…
Recently, vegan food has received increased attention from Italian consumers. Despite this fact, it has rarely been the subject of analysis. Our study focuses on consumer preferences for breadsticks in North-Eastern Italy. We applied a choice experiment where a hypothetical market was designed to analyze five characteristics of breadsticks (country of origin, vegan product certification, produc…
Phytospreading, proposed by S.V. Meyen, depends on the role of biological evolutionary “mechanisms”.Some biological species that occupy a vast territory from the equator to the mid latitudes break up into two areas and form two populations. Later, the conditions arise for these populations (new related species) convergence at equatorial or middle latitudes, resulting in the hybridization of…
Deficit irrigation is a common practice to cope with limited water availability. A two-year field experiment was conducted in order to determine the water status of cotton crop (Gossypium hirsutum L.) under full and deficit irrigation conditions. The experiment was set up as a split plot design with four replicates, two main plots (irrigation treatments) and two sub plots (cotton cultivars). …

The economic size of agricultural farms is defined by means of the standard output (SO). However, economic effects of these farms depend on the way of husbandry. The analysed family farms of the area ranging from 8.58 ha UAA to 150 ha UAA had economic sizes ranging from €9,737 to €24,9379. Such a range made it possible to create 4 groups of farms according to classes of the economic size ES…
