Research was made in Lunguletu, Dâmbovita County, an area in Romania with tradition in early potato culture. The biological material used was the Carrera variety, with tubers of two size categories (35-45 mm and 45-55 mm) and tuber fractions with 2-3 buds, cultivated in three culture systems (unprotected, protected with agril on the soil and protected with a tunnel made of agril), both sprouted and unsprouted. The results showed that the 35-45 mm tubers formed shorter stems compared to the 45-55 mm tubers and fractions, the plants’ growth being influenced also by the protection system. Thus, at the beginning, the plants protected by the agril tunnel recorded heights between 12.7 cm and 24.9cm, followed by the ones protected with agril on the soil, between 7.1 cm and 22 cm, while for the unprotected ones the height of the stems had values between 4 cm and 10.6 cm. The number of tubers per nest was larger for the 45- 55 mm tubers for all culture variants, having values between 12 and 14.6. The tuber production was influenced by the tuber preparation method and the culture system, the best results being obtained for the sprouted tubers for all studied variants, with values between 3919 g for the unsprouted tubers protected with agril on the soil and 8848 g for the sprouted tuber fractions protected with the agril tunnel.
