The effect of different phosphorus doses on seed yield and some quali̇ty trai̇ts of camelina (Camelina sativa (L.) Crantz)

This study, which was carried out to determine the effects of different phosphorus doses on the seed yield and some quality characteristics of camelina, was carried out in the experimental fields of Agriculture Faculty of Tekirdağ Namık Kemal University, located within the borders of the central Süleymanpaşa district of Tekirdağ province, in the south of the Thrace section in the north of the Marmara region. The study, was carried out in the Split Plots in Random Blocks Design with 3 replications. Three camelina genotypes (Ames 31224, PI 258366, PI 304268) from the Black Sea Agricultural Research Institute were used as plant material and 5 phosphorus doses and control (0, 2, 4, 6, 8, and 10 kg/da) were applicated to genotpes. In the experiment some morphological parameters such as plant height, number of branches, number of capsules, number of seeds per capsule, capsule diameter, days to maturity, seed yield, 1000 seed weight, and protein content, oil content and oil yield characteristics were investigated. According to the information obtained as a result of the research, the differences between genotypes and doses were found to be significant. When evaluated in general in the experiment, the effect on genotypes with the increase of phosphorus dose was observed to positive effect in plant height, number of seeds per capsule, oil yield, protein content, oil content, seed yield values, while number of branches, number of capsules, capsule diameter, days to maturity and 1000 seed weight negative effects were observed. In the study, it was concluded that the most optimal phosphorus dose for Tekirdağ ecological conditions is 6 kg/da and that increasing doses can have positive effects on quality traits
