Influence of Vermicompost Application on the Growth of Vinca rosea valiant, Pelargonium peltatum L. and Pegasus patio rose

Abstract

Vermicompost (VC) is a nutrient-rich material that is mixed with soil, and it is used in this study. Four different environments were created such as control (Soil:VC:100–0%), mix one (Soil:VC:70–30% w/w), mix two (Soil:VC:50–50% w/w), and mix three (Soil:VC:40:60% w/w), and three well-developed roses (Vinca rosea valiant, Pelargonium peltatum, Pegasus patio) seedlings were transferred to individual pots. Plant growth parameters, i.e., the number of flowers, plant height, stem diameter, chlorophyll reading value, fresh flower weight, and flower dry weight height, were compared with respect to control seedlings. The improvement in the number of flowers, plant height, stem diameter, chlorophyll reading value, fresh flower weight, and flower dry weight height by 264, 71, 58, 255, and 193% for Vinca rosea valiant rosea, 138, 12, 160, 13, 55 and 112% for P. patio rose, and 50, 14, 23, 8, 61, and 41% for P. peltatum, respectively, grown in soil mixed with VC as compared to control. As a result of the research, the optimum growth parameter values and chlorophyll Meter SPAD values were obtained from the mix-three mediums for all three roses species. These results showed that 40% soil and 60% VC application could be proposed as the most effective medium in ornamental plant production.

Do Vermicompost Applications Improve Growth Performance, Pharmaceutically Important Alkaloids, Phenolic Content, Free Radical Scavenging Potency and Defense Enzyme Activities in Summer Snowflake (Leucojum aestivum L.)?

“…Moreover, VC aids in the greater completion of root formation in plants, resulting in plants that take nutrients from the soil more readily and perform better in terms of growth [21] . Due to the presence of humic acid, which is a chemical similar to plant growth hormone, VC treatments have been proven in several studies to be able to improve plant growth parameters such as height, fruit yield, stem width, water content, flower width, leaf length, leaf number, and leaf area [22–30] . Balmori et al.…”

“…[21] Due to the presence of humic acid, which is a chemical similar to plant growth hormone, VC treatments have been proven in several studies to be able to improve plant growth parameters such as height, fruit yield, stem width, water content, flower width, leaf length, leaf number, and leaf area. [22][23][24][25][26][27][28][29][30] Balmori et al explained that the foliar application of humic extract from VC at a 1 : 40 (v:v) on Allium sativum was the best treatment for growth parameters. They found that the humic substance increased the fruit quality and improved the bulb diameter.…”

Organic inputs with reduced chemical fertilizers improve yield, antioxidant components, and defense mechanisms in Tomato (var. Pusa Sheetal)

“…The maximum plant height was recorded in T3, where a combination of organic and inorganic fertilizers was applied with reduced doses of NPK, resulting in a significant increase compared to the control. The study revealed that the application of recommended doses of Farm Yard Manure (FYM) and vermicompost (VC) and reduced doses of NPK significantly enhanced tomato plant growth [24], yield, and physiological attributes [25]. The correlation analysis results show that plant height, number of branches, and number of leaves are perfectly and positively correlated, suggesting that the taller the plant is equal to the larger the canopy size to capture more available resources and nutrients (Sunlight, moisture, nutrients, etc.…”

Ivy Geranium (Pelargonium peltatum (L.) L’Hér.) Plant Growth and Flowering as Affected by Mineral or Biofertilizer with or without Compost Amendment

“…Typically, 60-90% of whole applied fertilizers are mislaid, with only the remaining part (10-40%) being absorbed by plants. Hence, in order to fulfill the growing demand and stop overusing chemical resources, new sustainable and environmentally friendly solutions based on organic and biofertilizer amendments are needed [7,14,15].…”

“…Various agro-waste has long been deliberated as being of little value and is typically discarded. Research has shown, however, the practicability of utilizing this agro-waste, after composting, as a growing substrate for vegetables and ornamental plants for its nutrient-rich fertilization as a soil amendment [14,15,17]. The addition of compost to the soil has valuable impacts on plant establishment and productivity via increasing soil fertility and microbial activities [7,9].…”
