One of the greatest challenges in recent years is providing enough food to feed the increasing world population, with limited freshwater resources. However, effective fertiliser management also has a fundamental role to improve yield quality and quantity. Organic fertiliser not only supplements nutrients but also improves physicochemical and biological soil properties. A 2-year field experiment was conducted to examine the influence of urea and vermicompost fertiliser on oil phytochemical properties of peppermint pH, soil cation exchange capacity (CEC) and organic carbon of experimental site under three irrigation regimes in 2018 and 2019. The experiments had three water deficit regimes (no stress, moderate, and severe drought stress) as a main plot. The subplot division consisted of six fertiliser treatments: unfertilised (control); 140 kg urea ha−1; 105 kg urea ha−1 + 3.3 ton vermicompost ha−1; 70 kg urea ha−1 + 6.6 ton vermicompost ha−1; 35 kg urea ha−1 + 10 ton vermicompost ha−1; and 13.5 ton vermicompost ha−1. The maximum leaf area index (4.29) and dry matter weight (3,803 kg ha−1) were observed in control irrigation, while the highest essential oil content (0.97%) could be seen under mild water deficit stress. Additionally, the highest organic carbon and CEC were obtained under well-watered conditions at 1.20% and 6.41 (meq 100 g soil−1), respectively. Dry matter weight and essential oil content increased considerably in response to increasing vermicompost in fertiliser treatments, and the highest content of these traits were observed in 2019 and with 13.5 ton vermicompost ha−1. The menthol content increases in response to deficit irrigation and integrated fertiliser. These data indicate that mild drought stress can increase the synthesis of medical compounds and vermicomposting can alleviate the impact of drought by conserving soil moisture as an acclimation mechanism to improve nutrient uptake and avoid yield losses.

施肥处理和灌溉制度处理的薄荷 (Mentha piperita L.) 的农艺性状、土壤特性和精油成分之间是否有任何关系?

近年来最大的挑战之一是在淡水资源有限的情况下提供足够的食物来养活不断增长的世界人口。然而,有效的肥料管理对于提高产量质量和数量也具有根本性的作用。有机肥不仅可以补充养分,还可以改善土壤的理化和生物性质。2018 年和 2019 年,进行了为期 2 年的田间试验,研究了尿素和蚯蚓粪肥对 2018 年和 2019 年三种灌溉制度下试验地薄荷油 pH 值、土壤阳离子交换能力(CEC)和有机碳的影响。三个缺水状态(无压力、中度和严重干旱压力)作为主要情节。次小区划分由六种肥料处理组成:未施肥(对照);140公斤尿素公顷-1 ; 105 kg 尿素 ha -1  + 3.3 吨蚯蚓粪 ha -1;70 kg 尿素 ha -1  + 6.6 吨蚯蚓粪 ha -1;35 kg 尿素 ha -1  + 10 吨蚯蚓粪 ha -1;和 13.5 吨蚯蚓粪 ha -1。在对照灌溉中观察到最大叶面积指数 (4.29) 和干物质重量 (3,803 kg ha -1 ),而在轻度缺水胁迫下可以看到最高的精油含量 (0.97%)。此外,在充分浇水的条件下获得了最高的有机碳和 CEC,分别为 1.20% 和 6.41(meq 100 g 土壤-1), 分别。干物质重量和精油含量随着肥料处理中蚯蚓粪的增加而显着增加,这些性状的含量最高出现在 2019 年,13.5 吨蚯蚓粪 ha -1。薄荷醇含量会随着灌溉不足和综合施肥而增加。这些数据表明,轻度干旱胁迫可以增加药物化合物的合成,而蚯蚓堆肥可以通过保持土壤水分作为一种适应机制来提高养分吸收和避免产量损失,从而减轻干旱的影响。
