“…It was also observed that an optimal compost concentration with sufficient nutrient availability ensures an enhanced photosynthetic process, leading to an increase in photosynthates and the accumulation of carbohydrates that ultimately facilitate plant growth (Alidoust, Torkashvand, & Khomami, 2012). Additionally, the maximum length of lateral branches was found under the medium where compost was incorporated (Rakesh Kumar, Singh, Tomar, & Gupta, 2022). These findings correspond with the results documented in prior research that investigated the utilization of compost on calendula plants.…”

Zinnias originates from Mexico and has high demand in the floriculture market. The need to reduce reliance on chemical fertilizers has highlighted the importance of sustainable alternatives like organic manures. Compost application in horticulture is gaining attention as a sustainable alternative to chemical fertilizers, aiming to enhance soil health and plant growth. However, there is a limited understanding of its effects on the growth. This study investigates the effects of compost on the growth, flowering attributes, and vase life of Zinnia elegans to improve cultivation techniques and promote sustainable horticultural practices. The experiment used an RCBD with two factors. When they reached 3-5 true leaves, plantlets were transplanted into 12-inch pots with compost varying concentrations, including Control, 25%, 50%, and 100% with garden soil. Changing compost concentrations and zinnia varieties affected numerous factors strongly. Plant height, for instance, varied significantly, with Benary's Giant cultivar reaching the tallest (72.04 cm) under 50% compost, mirroring the stem diameter's peak at 1.01 cm with the same compost level. Compost levels and zinnia varieties also notably impacted leaf count, lateral branches, leaf area, flower count, and flower attributes like diameter and stalk length. The study also found that 50% of compost extended petal senescence survival. Compost and zinnia interaction affected the flower’s fresh weight and vase life. The interaction cultivar Benary,s Giant with 50% compost in garden soil was optimal for zinnia growth and flowering. This study will provide the basics for floriculture.

Coconut fiber has excellent permeability and water retention properties, making it a popular choice as an organic substrate for cultivation in the field of facility agriculture. To investigate the dielectric properties of coconut fiber and develop an accurate measurement model for dielectric water content, a vector network analyzer was used to measure the relative dielectric permittivity of coconut fiber and study the dielectric properties of coconut fiber under different volumetric water contents, temperatures, and salinities. The results indicated that the relative dielectric permittivity of the coconut fiber increased with increasing volumetric water content. The optimal frequency range for measuring the water content of the coconut fiber was 200 MHz–3 GHz, with an optimal frequency of 210 MHz. The dielectric measurement model for the water content in the coconut fiber established at this frequency demonstrated good applicability, with an R2 of 0.9704 and RMSE of 0.0453 cm3/cm3. At the same moisture level (θV of approximately 30% and 50%), the error in the real part of the dielectric permittivity was less than 1.35 between 15 and 35 °C, and the error in the moisture content was less than 0.0339 cm3/cm3. The error due to the salinity was 0.0750 cm3/cm3. The experimental results showed that the modeling of the water content measurement of coconut fiber at 210 MHz can be applied to general greenhouse environmental conditions. This study serves as a valuable reference for calibrating the moisture monitoring sensors used in greenhouses for coir cultivation substrates, emphasizing the need for non-destructive, real-time monitoring of moisture content.

“…Therefore, the need for a light-weight growing medium has become more desirable due to their portability and display during exhibitions and flower shows [8]. The various light-weight media, viz., cocopeat, farmyard manure, vermicompost, perlite, vermiculite, leaf-mould, etc., altered the physico-chemical characteristics of growing mixtures and affected the growth of potted ornamentals [9,10].…”

The use of different growing media offers a valuable alternative to the conventional use of soil for quality flower production due to their good water holding capacity, aeration and nutrient status. The experiment was conducted in a Completely Randomised Design with three replications in the years 2021–2022 to study the influence of different compositions of growing media [Soil, Sand, Vermicompost, Cocopeat, Vermiculite, Perlite and Leaf mould] in different ratios on the growth and development of pot mum (Chrysanthemum morifolium Ramat.).The growing media compositions of cocopeat, vermicompost and leaf moulds improve the water retention and aeration of media. The results revealed vegetative growth with maximum plant height at first bud appearance, plant height at harvesting stage, number of primary branches per plant, number of secondary branches per plant, number of leaves per plant, leaf biomass, average fresh weight of leaf, dry weight of root and flowering parameters with maximum flower longevity, flower diameter, number of flowers per plant, number of ray florets, average fresh weight of flower, flower yield per plant and vase life of flower in case of media composition of Cocopeat + Vermicompost + Leaf mould (2:1:1) among all the growing media compositions. The combination of cocopeat with vermicompost and leaf mould (2:1:1 v/v/v) was found best for lighter media weight, better plant morphological development and sustained quality flower production of pot mum.
