Abstract

Coriander (Coriandrum sativum L.) is a high-value seed spice and medicinal plant, yet its production in semi-arid regions is constrained by low soil fertility and crop lodging. A two-year field experiment (2024–2025) was conducted in Khoy, Iran, to evaluate the effects of foliar-applied vermicompost extract (0, 3000, 6000, and 12,000 ppm) and Nitroxin biofertilizer seed inoculation (with and without) on growth, yield, lodging incidence, and seed essential oil of coriander. Treatments were arranged as a 4 × 2 factorial in a randomized complete block design with three replications, and data from the two seasons were analysed jointly with year included in the model; year × treatment interactions were [not significant for any trait], so treatment responses were consistent across seasons. Vermicompost extract at 6000 ppm produced the greatest root length (12.21–12.50 cm), 1000-grain weight (1.50–1.55 g), and above-ground biomass (4161–4221 kg ha⁻¹) in 2024 and 2025, respectively, whereas grain yield was highest at 3000 ppm (257.0–262.1 kg ha⁻¹), indicating that the optimum concentration differed among traits. Both inputs reduced the lodging index, from 8.50 to 9.20% in the untreated control to 4.87–4.93% at 12,000 ppm vermicompost extract. Harvest index and essential oil content (2.11–2.35%) were not significantly affected by the treatments, and no significant vermicompost × Nitroxin interaction was detected for any trait. Gas chromatography–mass spectrometry of the seed oil identified 33 constituents (99.67–99.78% of the oil), dominated by linalool (73.26–74.10%), camphor (4.57–5.02%), and γ-terpinene (3.98–4.33%). Under the low-input conditions of this study, foliar vermicompost extract at 3000–6000 ppm improved grain yield and biomass and reduced lodging incidence of coriander without altering essential oil content, and the seed oil retained a linalool-rich composition suitable for organic production systems in semi-arid environments.

叶面蚯蚓堆肥提取物和氮素生物肥料对香菜（Coriandrum sativum L.）籽粒产量、倒伏发生率和种子精油特性的影响：在伊朗进行的为期两年的田间研究

芫荽（Coriandrum sativum L.）是一种高价值的种子香料和药用植物，但其在半干旱地区的生产受到土壤肥力低和作物倒伏的限制。在伊朗Khoy进行了为期两年的田间试验（2024-2025），以评估叶面施用蚯蚓堆肥提取物（0,3000,6000和12,000 ppm）和氮素生物肥料种子接种（带和不带）对香菜生长，产量，倒伏发生率和种子精油的影响。采用3个重复的随机完全区组设计，按4 × 2因子进行处理，两个季节的数据与纳入模型的年份联合分析；年×处理的相互作用[对任何性状都不显著]，因此处理反应在各个季节是一致的。蚯蚓堆肥提取液浓度为6000 ppm时，2024年和2025年的根长（12.21 ~ 12.50 cm）、千粒重（1.50 ~ 1.55 g）和地上生物量（4161 ~ 4221 kg ha−1）最大，而籽粒产量在3000 ppm （257.0 ~ 262.1 kg ha−1）时最高，说明不同性状间的最佳提取浓度存在差异。两种投入物均降低了倒伏指数，从未处理对照的8.50 ~ 9.20%降至12,000 ppm蚯蚓堆肥提取物的4.87 ~ 4.93%。各处理对收获指数和挥发油含量（2.11% ~ 2.35%）均无显著影响，且各性状均未检测到蚓粪与氮素的交互作用。气相色谱-质谱联用分析鉴定出33种主要成分，占总含量的99.67 ~ 99.78%，主要成分为芳樟醇（73.26 ~ 74.10%）、樟脑（4.57 ~ 5.02%）和γ-萜烯（3.98 ~ 4.33%）。在本研究的低投入条件下，3000-6000 ppm的叶蚯蚓堆肥提取物在不改变香菜精油含量的情况下提高了香菜的产量和生物量，降低了倒伏发生率，种子油保留了富含芳樟醇的成分，适合半干旱环境下的有机生产系统。
