Abstract:
The influence of joint applications of N and S on false flax (Camelina sativa L.) growing was studied in a pot experiment. Nitrogen was applied as NH4NO3 at rates of 0.6 (N-1)- 0.9 (N2()) - 1.2 (N-3) g per pot. Sulphur was applied as (NH4)(2)SO4 to achieve levels of 35 ppm (S-1) and 55 ppm (S-2) S-SO42-. The number of branches per plant increased with the nitrogen doses (10.62-12.41-15.38). The N-2 and N-3 rates (4.91 g and 4.79 g, respectively) significantly increased the seed yields (g/plant) as compared to Ni (3.77 g). Straw yields (g/plant) and thousand-seed weight (g) increased significantly only with the highest level of nitrogen N-3 (18.23 and 1.17, respectively) compared to Ni (16.52 and 1.06, respectively). Increasing levels of nitrogen (N-1-N-2-N-3) reduced the oil content of seeds (40.79-38.40-37.66%), but increased the protein content (23.93-25.63-28.19%). The level of sulphur 53 significantly stimulated only the oil content to 39.36% compared to 38.54% with Si. At the same time a negative correlation was discovered between the oil and protein content in the seeds (r=-0.8164). The applied doses of nitrogen N-2 and N-3 significantly increased the total oil yields (1.88-1.80 g/plant) as well as the total protein yields (1.25-1.35 g/plant) compared to N-1 (1.53 and 0.90 g/plant, respectively).
