Researches regarding the influence of technological sequences on the yields of tubers and biomass at Jerusalem artichoke under the conditions of A.R.D.S. Secuieni

Abstract

The paper aims to highlight the influence of the distance between tubers in a row and the nutrition system of the Jerusalem artichoke plant on the yields of tubers and biomass. The research was conducted between 2018 and 2019, in the experimental field of A.R.D.S. Secuieni. The obtained results showed that the studied factors influenced to a great extent the tuber yield obtained. Thus, the yield of tubers varied within wide limits, being between 23.16 t / ha (40 cm x N0P0K0) and 32.77 t / ha (50 cm x N120P120K80). The interaction of the studied factors influenced the yield of biomass at Jerusalem artichoke, ranging from 25.15 t / ha (40 cm x N0P0K0) to 35.45 t / ha (50 cm x N120P120K80).
