Vermi-composting is an environmental friendly and economic process to decompose organic waste. The objective of this study was to produce vermi-compost using and to investigate the impact of vermi-compost (VC) and organic manure (cow dung) on seed germination, seedlings, and growth parameters of . Physio-chemical parameters of vermi-compost and organic manure were recorded. A potting experiment was designed, germination medium containing soil, sand, and various concentrations of vermi-composts. The composition of germinating media was: TO (Sand + Soil), TCC (Sand + Soil + Cow dung), 10% VC (Sand + Soil + 0.1 kg VC), 15% VC (Sand + Soil + 0.15 kg VC), 20% VC (Sand + Soil + 0.2 kg VC), 25% VC (Sand + Soil + 0.25 kg VC), 30% VC (Sand + Soil + 0.3 kg VC), and 35% VC (Sand + Soil + 0.35 kg VC). Seed germination, seedling, vegetative plant growth, and flowering parameters were evaluated in different germinating media. Pre and post-physio-chemical parameters of germination media were also recorded to check their stability and quality. Results showed that 20% VC was effective for the early initiation of seed germination (2.0 ± 0.0 days) and all growth parameters of marigold seedlings. The germination percentage at 20% VC was recorded as 87.5 ± 1.40 %. The best vegetative plant growth and flowering parameters of marigold plants were observed with 35% VC after transplantation. Findings showed that vermi-compost is the best-suited germination and growing media, which not only improved the soil health but also promoted seed germination and plant growth. Our study undoubtedly indicates that vermi-compost is a more encouraging and advantageous bio-fertilizer and can be used as a powerful and effective for immediate marigold production.
蚯蚓堆肥是一种环保且经济的有机废物分解过程。本研究的目的是利用[具体内容缺失]生产蚯蚓堆肥，并研究蚯蚓堆肥（VC）和有机肥料（牛粪）对[植物名称缺失]种子萌发、幼苗及生长参数的影响。记录了蚯蚓堆肥和有机肥料的理化参数。设计了一个盆栽实验，发芽培养基包含土壤、沙子和不同浓度的蚯蚓堆肥。发芽培养基的组成如下：TO（沙子+土壤）、TCC（沙子+土壤+牛粪）、10% VC（沙子+土壤+0.1千克VC）、15% VC（沙子+土壤+0.15千克VC）、20% VC（沙子+土壤+0.2千克VC）、25% VC（沙子+土壤+0.25千克VC）、30% VC（沙子+土壤+0.3千克VC）和35% VC（沙子+土壤+0.35千克VC）。在不同的发芽培养基中评估种子萌发、幼苗、植物营养生长和开花参数。还记录了发芽培养基的前后理化参数，以检查其稳定性和质量。结果表明，20% VC对万寿菊种子萌发的早期启动（2.0±0.0天）和万寿菊幼苗的所有生长参数均有效。20% VC时的发芽率记录为87.5±1.40%。移植后，35% VC的万寿菊植株营养生长和开花参数最佳。研究结果表明，蚯蚓堆肥是最适合发芽和生长的培养基，不仅改善了土壤健康状况，还促进了种子萌发和植物生长。我们的研究无疑表明，蚯蚓堆肥是一种更具吸引力和优势的生物肥料，可作为万寿菊即时生产的强效有效肥料。
