摘要

春季期间研究(2022),以确定早期的影响种植四种植日期(18/1 / 2 17 / 2和4/3/2022),和四个层次的钾肥(30、60、90和120年)公斤农业,向日葵产量和丰满的谷物,品种Shamoos,由安排分割板根据随机完全区组设计有三个复制实验的结果显示重要的种植日期对经济增长的影响,在产量和品质性状方面,由于D4的植树期优于营养生长性状(50%开花和株高),在这两个性状中平均最高,达84.58天,274.30 cm。在产量性状及其组成方面,D1超过了全粒数、千粒重和单株产量的性状,其平均值最高,分别为1281.13粒,128.65 g和165.12 g。试验结果表明,钾水平对营养生长、产量和品质的影响显著,其中K4施肥处理对50%花序和饱满种子数的平均值最高,分别达到84.58 d和1047.30粒盘-1,而K2施肥处理对叶片钾含量和千粒重的平均值最高,分别为4.29%和120.78 gm。

Effect of planting dates and potassium levels on the growth and yield of sunflowers
The study was conducted during spring season (2022), to determine the effect of early planting for four planting dates (18/ 1, 2/ 2, 17/ 2 and 4/3/2022), and four levels of potassium fertilizer (30, 60, 90 and 120) kg ha-1 , on the yield and fullness of sunflower grains, cultivar Shamoos, was carried out by arranging the split panels according to a Randomized Complete Block Design with three replicates The results of the experiment showed significant effects of planting dates on growth, yield and quality traits, as the D4 planting date was superior to vegetative growth traits (50% flowering and plant height) by giving it the highest average of these two traits, which amounted to 84.58 days and 274.30 cm. giving it the highest average for the trait, which reached 4.35% As for the yield traits and its components, the planting date D1 exceeded the characteristics (number of full seeds, weight of 1000 seeds and yield of individual plant) as it gave the highest average of these traits amounted to (1281.13 seeds disc-1 , 128.65 g and 165.12 g) respectively. The results of the experiment showed a significant effect of potassium levels on the characteristics of vegetative growth, yield and quality, as the K4 fertilization treatment gave the highest average for the traits (50% inflorescence and the number of full seeds), which reached (84.58 days and 1047.30 seeds disc-1 ) respectively, while the K2 fertilization treatment gave The highest mean of potassium content in leaves and weight of 1000 seeds was 4.29% and 120.78 gm.
