Pepper ( L.) is an important agricultural crop because of the nutritional value of the fruit and its economic importance. Various techniques have been practiced to enhance pepper's productivity and nutritional value. Therefore, this study was conducted to determine the impact of different training methods and biostimulant applications on sweet pepper plants' growth, yield, and chemical composition under greenhouse conditions. For the training method, unpruned plants were compared with one stem and two stem plants. Unpruned plants had the fruit number of 33.98, fruit weight of 2.18 kg·plant, and total marketable yield of 1 090.0 kg·hm. One stem plant gave the best average fruit weight of 86.63 g, vitamin C content of 13.66 mg·kg FW, and TSS content of 7.21%. However, two stem plants had the highest fruit setting of 62.41%, carotenoid content of 0.14 mg·kg FW, and fruit chlorophyll content of 3.57 mg·kg FW. For biostimulant applications, control plants were compared with the Disper Root (DR) and Disper Vital (DV). DR application significantly increased total sugar, carotenoid, fruit chlorophyll, and TSS contents compared to the control and DV applications. While, applying DV increased fruit setting, plant fruit number, weight, and total marketable yield. In addition, integrating one stem plant with the DR application improved fiber, vitamin C, and TSS contents significantly. Two stem plants, and the DV application improved fruit setting and carotenoid content. Thus, one and two stem training methods integrated with the DR and DV biostimulant applications could be considered for developing agricultural practices to obtain commercial yield and improve the nutrition values of sweet peppers, as unpruned plants without biostimulant applications have a negative impact.

训练方法和生物刺激素应用对甜椒（Capsicum annuum）产量和营养价值的影响：温室条件下

胡椒（L.）因其果实的营养价值及其经济重要性而成为一种重要的农作物。人们已经采用了各种技术来提高辣椒的产量和营养价值。因此，本研究旨在确定温室条件下不同培养方法和生物刺激素应用对甜椒植物生长、产量和化学成分的影响。对于训练方法，将未修剪的植物与一茎植物和两茎植物进行比较。未修剪植株的果数为33.98个，单果重2.18 kg·株，商品总产量1 090.0 kg·hm。单株平均单果重最高，为86.63 g，维生素C含量为13.66 mg·kg FW，TSS含量为7.21%。其中两种茎植株的坐果率最高，为62.41%，类胡萝卜素含量为0.14 mg·kg FW，果实叶绿素含量为3.57 mg·kg FW。对于生物刺激剂应用，将对照植物与 Disper Root (DR) 和 Disper Vital (DV) 进行比较。与对照和DV施用相比，DR施用显着增加了总糖、类胡萝卜素、果实叶绿素和TSS含量。同时，施用 DV 可以提高坐果率、果实数量、重量和总销售产量。此外，将一株茎植物与 DR 应用相结合显着提高了纤维、维生素 C 和 TSS 含量。两种茎植物和 DV 施用提高了坐果率和类胡萝卜素含量。因此，可以考虑将一种和两种茎培养方法与 DR 和 DV 生物刺激剂应用相结合来发展农业实践，以获得商业产量并提高甜椒的营养价值，因为未经修剪的植物而不应用生物刺激素会产生负面影响。
