Effect of fertilization with N-inhibitors on root and crop development of flaxseed crop (Linum usitatissimum L.) .

摘要

Flax ( Linum usitatissimum L. cv. Everest ) is a crop whose products can be used in a variety of ways such as industrial use, human consumption and fiber production. Nitrogen seems to have a positive effects on flaxseed cultivation. Two same experiments set up in 2018- 2019, in Western Greece. It has been studied how three combinations of urea affect flaxseed cultivation. More specifically, the combinations of urea used are only urea, urea with urease inhibitor and urea with urease inhibitor and nitration inhibitors. The studied characteristics were agronomic characteristics such as the LAI and the plants’ height as well as roots characteristics such as density and arbuscular mycorrhizal (AM) symbiosis. In addition, some nitrogen markers, such as NUE and NHI, have been studied in order to evaluate better urea combinations. The aim of this study was to observe the effects of inhibitors on flaxseed crop compared with urea only and control. The comparisons were made at a 5% significance level (p ≤ 0.05). Urea with double inhibitors has been shown to have the most beneficial effects in all parameters studied.
