The aim of this research was to determine the economic efficiency of sweet potato production in Polish conditions (49°49′ N, 21°50′ E). The study was based on the results of a 3-year (2017-2019) field experiment conducted in slightly acidic brown earth. The experiment used the random subblocks method, in which the main experimental factors were cultivation technologies: A) traditional, with no cover, B) with the use of PP spunbond nonwoven. Secondary factors included 5 cultivars of sweet potato of all earliness classes (Goldstar, Carmen Rubin, Satsumo Imo, Beauregard, White Triumph). Constant organic and mineral fertilization was used, and cultivation was carried out in accordance with normal agricultural practice. The propagating material included rooted cuttings of sweet potato from in vitro propagation, planted with 50 x 75 cm spacing. The economic effect of production was determined by all experimental factors. The profitability of production was increased by the use of PP spunbond nonwoven. The most beneficial economic factors were achieved when growing the Beauregard cultivar, and the least – when growing White Triumph. The largest cost of sweet potato commercial production were sweet potato cuttings, which amounted to 56%, and the smallest – plant protection products – 1% of direct costs per 1 ha of crops. Sweet potato production in Polish soil and climate conditions between 2017–2019 turned out to be cost-effective.

Przedstawiono wybrane aspekty podejmowanych działań innowacyjnych przez podmioty rolnicze. Ukazano problematykę innowacyjności na przykładzie dwóch spółdzielni rolniczych z województwa podkarpackiego. Badania wykazały, że innowacje wprowadzane przez badane spółdzielnie miały głównie charakter innowacji technologicznych, a w niewielkim stopniu nietechnologicznych. Głównym efektem podejmowania tego rodzaju działań było obniżenie kosztów produkcji oraz wejście na nowe rynki zbytu.

The study presents the innovative activity undertaken by agricultural cooperatives located in the Podkarpackie province. Researches showed that innovations implemented by the cooperatives mainly had the character of technological innovations, and in a small extent – non-technological character. When analyzing particular groups of cooperatives with different level of innovation, it was found that the most pro-development behaviors was observed in the I RSP group with a high level of innovation.

In the paper the activities undertaken by a group of agricultural producers as a manifestation of innovative activities were presented. The study was carried out in the province of Podkarpackie province among producers cereal grains and oilseeds using the method of questionnaire, interview with randomly selected members of the group in 2012. The paper argues that undertaking joint initiatives allows for achieving tangible benefits and opportunities to gain competitive advantage. Research showed that horizontal integration in apart from the undoubted benefits, is associated with numerous difficulties, the most important of which is the lack of confidence among farmers and misunderstandings and conflicts.
