Determination of the effect of different nitrogen andphosphorus levels on some agronomic and quality propertiesin linen (Linum usitatissimum L.)

Flax (Linum usitatissimum L.) is a species of the genus Linaceae that contains 13 genera and 300 species. In this study, some yield and quality components of 5 different nitrogen (control, 6.0, 7.5, 10.0 and 12.0 kg / da) and phosphorus doses (control, 3.0, 5.0, 7.5, and 10.0 kg / da) application in Diyarbakır in 2019. In order to determine the optimum nitrogen and phosphorus doses, randomized blocks were carried out in 3 replications according to the experimental design. Sarı-85 cultivar was used as material in the research and plant height, number of branches in the plant, technical stem length, number of capsules in the plant, number of capsules in the plant, biological yield, seed yield, thousand seed weight, constant oil ratio, constant oil yield, fatty acid composition properties were examined. According to fertilizer doses, plant height was between 47.73 cm and 38.90 cm, number of branches per plant between 5.76 (pieces/plant) and 3.86 (pieces/plant), technical stalk length between 30.06 cm and 26.66 cm, number of capsules between 25.67 (pieces/plant) and 13.40 (pieces/plant), number of seeds per capsule between7.16 (pieces/capsule) and 5.86 (pieces/capsule), biological yield from 102.20 (kg/da) to 189.10 (kg/da), seed yield from 24.35 (kg/da) to 46.72 (kg/da), thousand grain weight from 3.91 g to 6.26 g, fatty oil content of between 37.75% and 23.05% fatty oil yield was determined between 17.23 (kg/da) and 5.72 (kg/da).
