ترجمة الملخص

A field experiment was carried out in one of the fields followed to the Al-Diwaniyah Agriculture Directorate at Al-Nouriah Forest Station, located in Al-Shafi’iya district, 15 km southwest of Al-Diwaniyah city, during the winter seasons 2019-2020 and 2020-2021, with the aim of studying and screening the effect of different levels of the fertilizer combination of NPK and distribution of plants on some characteristics of vegetative growth, yield and its components of safflower (Carthamus tinctoriusL.) to determine the most appropriate fertilizer combination and planting distance between plants, a randomized complete block design (RCBD) was used arranged of split plot design with three replications the main plots included four levels of fertilizer combinations: (N0, P0, K0), (N140, P80, K40), (N160, P100, K60), (N180, P120, K80) and kg h-1which represented (F1, F2, F3and F4) respectively, as for the spilt plots, it included five distance between plant (30 × 30), (40 × 40), (50 × 50) (60×60) and(70×70) which represented (D1, D2, D3, D4 and D5) respectively. The fertilizer combination F4 (N180, P120, K80) recorded the highest averages for the characteristics of the study, including the leaves content of nitrogen, phosphorous, potassium, number of days from planting up to 75% flowering, plant height, number of branches for the first season only, number of plant leaves, petals yield for the first season Only with an average of 2.04 g. The fertilizer mixture F3 recorded superiority for leaf area and without significant differences with F4 for the two seasons in succession As for the yield and its components, the F4 fertilizer combination was also superior in the characteristics of the number of seeds per head for the first season only, the weight of 500 seeds and no significant differences with F3, plant yield, seed yield for the second season only, the total oil yield (52.88 seeds. head-1), (23.95 ,23.12 g), (118.03 ,113.24 g), (4.72th-1) and (1,656 and 1.607 th-1)for the traits and the two seasons sequentially, while the fertilizer F2 combination excelled as a harvest guide with an average of 33.22% for the second season only and without significant differences with F4. As for the effect of plantdistribution, the distance D5(70 x 70 cm) was superior in the characteristics of the number of branches, the number of leaves, the leaf area for the second season only. As for the characteristics of the yield and its components, it also excelled in most of the characteristics of the yield and its components, as it gave the highest average number of heads per plant. It reached (88.63,83.14 heads. plant-1) for the two seasons consecutively, and the number of seeds per head was 49.82 seeds. head-1, in the second season, the distance D4 (60 x 60 cm) was superior in the number of head seeds with an average of 44.88 seeds. The oil content in the seeds with an average of (34.60 and 35.09%) for the two seasons respectively, while the total seed yield and biological yield, the agricultural distance D1 outperformed with averages of (5.93 and 5.52tons.ha-1) and (19.99 and 20.78 t h-1) (1.829 and 1.669t h-1) for two seasons. As for the interaction between fertilizer combinations and planting distances, the interaction (F4×D5) gave the highest average weight of 500 seeds (27.07 and 25.00 g) for the two seasons in succession, and the plant yield was 160.50 for the second season only, and the interaction (F3×D1) gave the highest average seed yield of 6.54 t h-1for the second season only, which did not differ significantly from (F4×D1).
