刺槐(L.)Skeels是摩洛哥的特有物种,具有多种用途。它在植物学方面发挥着多重重要作用,生态,和经济属性。然而,该物种的驯化将为摩洛哥带来可观的经济机会。这里,第一次,我们评估了不同剂量的堆肥和NPK肥料对营养生长参数的影响,刺槐植物的生化和抗氧化潜力,和土壤性质。在两年期间(2022-2023年),在两个实验地点应用了八种不同的处理方法。这些治疗包括:T0(对照),T1(F1-80.50.70gNPK/植物),T2(F1-125.75.100克NPK/植物),T3(F2-160.100.140gNPK/植物),T4(F2-250.150.200gNPK/植物),T5(F1-2.5公斤/植物堆肥),T6(F1-5公斤/植物堆肥),T7(F2-5公斤/植物堆肥),和T8(F2-10公斤/植物堆肥),F1和F2是应用的频率。我们比较了几种没有施肥的肥料作为对照。结果表明,堆肥和NPK肥料对营养生长参数有显着影响。对于Tamjlojt网站,第一年很重要,因为治疗T3和T4显着增加身高71.94±21.15%和74.31±12.31%,分别。对于周长,结果表明,T4和T3处理显着改善,T1表现出最高的增益。对于套环直径,所有处理均表现出显著差异。处理T3和T7的差异最显著,分别为115.63±33.88%和101.09±20.84%,分别。对于Rasmouka网站,第二年是最重要的。身高增加最重要的处理是T7和T8,分别为43.14±10.06%和36.44±9.95%;领口直径也是如此,因为在T8和T7中发现了显着增加,分别为55.05±15.7%和54.08±9.64%。对于周长参数,显着增加该参数的治疗方法是T8和T7,在2023年分别为53.36±15.11%和50.34±11.29%。此外,处理T3的碳水化合物含量最高,为148.89±8.11(mgEG/g).对于酚类测定,最高值为2532±457.13(µgGAE/mL),显示治疗T1。对于类黄酮,表现出显着效果的处理是T1和T6,值为2261.98±184.61和1237.70±95.65(µgQE/mL),分别。对于土壤特性的影响,导电性,在Tamjlojt现场,治疗T1显着增加至1139.00±241.30(ms/cm),在Rasmouka现场,处理T8显示显着增加至303.33±9.33(ms/cm)。关于有机碳,所有处理都导致该参数在土壤中的百分比增加。对于Tamjlojt网站,T7治疗对该参数具有显著的正效应,值为0.87±0.12%。对于Rasmouka网站,T3处理使有机碳的百分比增加了1.17±0.07%。此外,有机质含量有所改善,为2.02±0.12%。由于以前没有关于刺鼻阿甘受精的研究,这项研究大大有助于我们理解使用不同剂量的不同肥料的好处,特别是T8和T7作为有机肥料,T3,T4作为化学肥料,关于摩洛哥的增长,叶子的生化和抗氧化特性,和它的土壤性质。
Argania spinosa (L.) Skeels is an endemic species to Morocco that has multiple uses. It plays multiple important roles in terms of its botanical, ecological, and economic properties. However, the domestication of this species will open up considerable economic opportunities for Morocco. Here, for the first time, we assessed the effect of different doses of
compost and NPK fertilizers on the vegetative growth parameters, biochemical and antioxidant potential of the Argania spinosa plant, and soil properties. Over a two-year period (2022-2023), eight different treatments were applied across two experimental sites. These treatments included the following: T0 (Control), T1 (F1-80.50.70 g NPK/plant), T2 (F1-125.75.100 g NPK/plant), T3 (F2-160.100.140 g NPK/plant), T4 (F2-250.150.200 g NPK/plant), T5 (F1-2.5 kg/plant
compost), T6 (F1-5 kg/plant
compost), T7 (F2-5 kg/plant
compost), and T8 (F2-10 kg/plant
compost), with F1 and F2 being the frequencies of application. We compared several doses of fertilizers with no fertilization as a control. The results showed a significant influence of the
compost and NPK fertilizer on the vegetative growth parameters. For the Tamjlojt site, the first year is important because treatments T3 and T4 significantly increased height by 71.94 ± 21.15% and 74.31 ± 12.31%, respectively. For the circumference, the results showed a significant improvement by the treatments T4 and T3, and T1 demonstrated the highest gain. For the collar diameter, all treatments showed a significant difference. The most notable difference was observed with treatments T3 and T7 with 115.63 ± 33.88% and 101.09 ± 20.84%, respectively. For the Rasmouka site, the second year was the most important. The treatments with the most important height increase were T7 and T8, with a value of 43.14 ± 10.06% and 36.44 ± 9.95%; the same was observed for collar diameter as a significant increase was found in T8 and T7 with a value of 55.05 ± 15.7% and 54.08 ± 9.64%. For the circumference parameter, the treatments that increased significantly this parameter were T8 and T7 with a value of 53.36 ± 15.11% and 50.34 ± 11.29% in 2023. In addition, the highest content of carbohydrates was recorded for the treatment T3 with a value of 148.89 ± 8.11 (mg EG/g). For phenolic determination, the highest value was 2532 ± 457.13 (µg GAE/mL), shown for treatment T1. For flavonoids, the treatments that showed a significant effect were T1 and T6 with a value of 2261.98 ± 184.61 and 1237.70 ± 95.65 (µg QE/mL), respectively. For the impact on soil properties, the electrical conductivity, at the Tamjlojt site, treatment T1 showed a significant increase to 1139.00 ± 241.30 (ms/cm), while at the Rasmouka site, treatment T8 showed a significant increase to 303.33 ± 9.33 (ms/cm). Concerning organic carbon, all treatments resulted in increased percentages of this parameter in the soil. For the Tamjlojt site, the T7 treatment had a significant positive effect on this parameter with a value of 0.87 ± 0.12%. For the Rasmouka site, the T3 treatment increased the percentage of organic carbon with a value of 1.17 ± 0.07%. In addition, the organic matter content showed an improvement with a value of 2.02 ± 0.12%. As there are no previous studies in Argania spinosa fertilization, this study greatly contributes to our understanding of the benefits of using different fertilizers at different doses, in particular T8 and T7 as organic fertilizers and T3, T4 as chemical ones, on argan growth, the biochemical and antioxidant properties of leaves, and its soil properties.
