The environmental and health concerns connected with the fly ash dumpsite could be avoided by using non-food crops to phytostabilize the site, keeping pollutants from moving and providing extra economic benefits. Fly ash amendments with nutrient-rich vermicompost have the potential to improve soil quality and availability, leading to increased crop productivity. Given the crop's importance and knowledge of fly ash and vermicomposting, this study aims to enhance commercial rosa grass development while avoiding using chemical fertilizers and low-cost inputs like fly ash and vermicompost. As a result, the current research is intended to identify the best fly ash (FA) and vermicompost (VC) ratios to enhance the commercial development of palmarosa while lowering the use of chemical fertilizers. We evaluated the effects of various fly ash and vermicompost levels on the growth, production, and quality of palmarosa essential oil to find the optimal fly ash dose. The experiment was set up with three replications with a total plot size of 3.8 × 3.8 m (a net plot area of 3.6 × 3.6 m). A space of 60 × 60 cm was used between the rows and plants for all treatments. Table 1 contains treatment information. Porosity varied significantly, with 100 % VC having much higher porosity (52.8 %) than the other treatments. In all five harvests, T3 (20 % FA + 80 % VC) produced significantly more biomass than the treatments T1 and T2 (first harvest = 8.2, second harvest = 9.0, third harvest = 9.4, fourth harvest = 8.9, and fifth harvest = 8.4 t/ha, respectively). Similarly, 20 % FA + 80 % VC produced essential oil yields comparable to T3 (257.6 kg/ha) and much greater than the other treatments (T2, 266.9 kg/ha). T2 and T3, on the other hand, exhibited higher gross returns, net returns, and B: C ratios. In a nutshell, the study provides an amazing novelty or inventory of potential future advantages and shows how fly ash combined with vermicompost can improve the biomass and essential oil production of Rosa grass. T3 biomass yields were significantly greater than T1 and T2 (80 % VC and 20 % fly ash) in all five of the harvests: 8.2 t/ha, 9.0 t/ha, 9.4 t/ha, 8.9 t/ha, and 8.4 t/ha, respectively. T3 (20 % FA + 80 % VC), produced more essential oil than the other treatments (T2, 266.9 kg/ha).

芳香蔷薇草对不同比例粉煤灰和蚯蚓粪的响应


通过使用非粮食作物来稳定垃圾场、防止污染物移动并提供额外的经济效益，可以避免与飞灰垃圾场相关的环境和健康问题。粉煤灰改良剂与营养丰富的蚯蚓堆肥有可能改善土壤质量和可用性，从而提高作物生产力。鉴于该作物的重要性以及粉煤灰和蚯蚓堆肥的知识，本研究旨在促进商业蔷薇草的发展，同时避免使用化肥和低成本投入，如粉煤灰和蚯蚓堆肥。因此，当前的研究旨在确定飞灰（FA）和蚯蚓粪（VC）的最佳比例，以促进棕榈树的商业发展，同时减少化肥的使用。我们评估了不同粉煤灰和蚯蚓堆肥水平对玫瑰草精油生长、产量和质量的影响，以找到最佳粉煤灰剂量。该实验设置了三个重复，总样地大小为 3.8 × 3.8 m（净样地面积为 3.6 × 3.6 m）。所有处理的行和植物之间使用 60 × 60 厘米的空间。表 1 包含治疗信息。孔隙率变化很大，100% VC 的孔隙率 (52.8%) 比其他处理高得多。在所有五次收获中，T3（20% FA + 80% VC）产生的生物量显着高于处理 T1 和 T2（第一次收获 = 8.2，第二次收获 = 9.0，第三次收获 = 9.4，第四次收获 = 8.9，第五次收获 =分别为 8.4 吨/公顷）。同样，20% FA + 80% VC 产生的精油产量与 T3（257.6 kg/ha）相当，并且远高于其他处理（T2，266.9 kg/ha）。 另一方面，T2 和 T3 表现出较高的总回报、净回报和 B:C 比率。简而言之，这项研究提供了令人惊叹的新颖性或未来潜在优势的清单，并展示了粉煤灰与蚯蚓堆肥的结合如何提高罗莎草的生物量和精油产量。在所有五个收获中，T3 生物量产量均显着高于 T1 和 T2（80% VC 和 20% 飞灰）：8.2 吨/公顷、9.0 吨/公顷、9.4 吨/公顷、8.9 吨/公顷和 8.4 吨/ha，分别。 T3（20% FA + 80% VC）比其他处理（T2，266.9 kg/ha）产生更多的精油。
