RESEARCH ON ESTABLISHING ECHNOLOGICAL PARAMETERS WITH HIGH EFFICIENCY IN JERUSALEM ARTICHOKE CULTURE

In the period 2018-2020. within RDSFCSS Dabuleni, from Romania, 4 planting epochs were studied and 2 harvest epochs. Determinations were made on the number of tubers/plant, the average weight of a tuber and the production per unit area. Regardless of the planting epoch both the number of tubers/plant and the average weight of a tuber was higher in the plants harvested after 29 weeks after planting. The highest production of tubers was obtained by planting Jerusalem artichoke between April 15-25 and harvested after 29 weeks. In this variant. the production was 66.02 t / ha. corresponding to a number of 45.9 tubers / plant. with an average weight of 47.8 g / tuber
