Climate change has made mandatory the introduction of new crops in Greece, such as
the cultivation of camelina [Camelina sativa (L.) Crantz]. Nitrogen (N) and the development of
root system are two important factors affecting crop growth and yield. Camelina has been studied
mainly for its composition and oil. In the present study, root development of camelina crop was
thoroughly investigated; mainly in terms of Nitrogen fertilization. Therefore, a camelina
greenhouse experiment was established in Western Greece, in the region of Agrinio, in March
2019 in completely randomized design with four treatments, (control 0 ppm N, 30 ppm N,
60, ppm N and 90 ppm N). The N rates had statistically significant affected root density and root
surface from 40 to 120 days after treatment (DAT) with highest values at 100 DAT and 90 ppm
N, 52.54 cm of root 100 cm-3 and 27.59 cm2 of root 100 cm-3
, respectively. The root volume was
significantly affected by N fertilizer from 40 to 100 DAT and highest value was 13.18 cm3 of
root 100 cm-3
soil in the 90 ppm at 120 DAT. The plant leaf area was significantly affected by
the highest rate of N. Yield per plant had not statistically significant difference with the 60 and
with the 90 and highest weight per plant 292.25 g plant-1
in 90 ppm. In conclusion, Ν fertilization
significantly affected growth or camelina’s root system after 40 DAT. Plant growth was
significantly affected by fertilization and the highest yield and 1,000 seed weight were recorded
with the highest amount of N
