Aims: This research was conducted to investigate the effect of different nitrogen fertilizer levels and planting density on grain yield and yield components of Camelina in Khuzestan.
Materials and Methods: The experiment was carried out in a split plot design based on randomized complete block design with four replications at the Behbahan agriculture research station during 2021-2022 growin season. Nitrogen was applied at five levels (0, 50, 100, 150, and 200 kg.ha-1 of pure nitrogen) in the main plots, and planting density was set at four levels (200, 400, 300, and 500 plants per square meter) in the sub-plots.
Results: the highest grain yield (2442 kg.ha-1) and oil yield (857 kg.ha-1) were obtained in consumption of 150 kg.ha-1 of nitrogen and a planting density of 300 plants per square meter. In planting densities of 200 and 300 plants per square meter, with increasing nitrogen up to 150 kg.ha-1, the grain yield increased and then decreased, while in planting densities of 400 and 500 plants per square meter, the yield increased linearly with increasing nitrogen application.
Conclusion: Increasing nitrogen application up to 150 kg.ha-1 resulted in increased grain yield of camelina. A planting density of 300 plants per square meter provided favorable conditions for plant growth and development, leading to increased grain and oil yield. Therefore, considering environmental conservation and resource management, a planting density of 300 plants per square meter and the application of 150 kg.ha-1of nitrogen can be utilized to achieve the highest grain and oil yield in camelina.
