Effect of Different Growing Media on the Growth and Development of Zinnia (Zinnia elegans) under the Agro-Climatic Condition of Jiroft

Abstract

Zinnia elegans, an annual flowering plant of the genus Zinnia, is one of the best known zinnias. Present study was conducted to evaluate the effect of different growing media on the growth and flowering of Zinnia elegans. Seven different growth media including coconut compost, silt, soil loam, leaf manure, (leaf manure+silt; 2:1), (coconut compost+soil loam; 1:1) and (leaf manure+soil loam+silt; 1:1:1) were used for growing Zinnia. The experiment was laid out in Complete Randomized Design (CRD) giving equal importance to treatments. Number of flowers, length of lateral branches, number of lateral branches, stem diameter, plant height (cm), diameter of flower, vase life (day) and fresh and dry root, shoot and total were determined. The present study confirms the fact that selection of the appropriate medium of growth for potted flowering plants in this case Zinnia elegans was very important from aesthetic and marketing point of view. The medium must ensure the production of plants of the required quality on cost effective basis. In the present study, leaf manure produced significantly the maximum vase life and diameter of flower while the maximum vase life and diameter of flower was obtained with mix (coconut compost+soil loam; 1:1).

Impact of Growing Media and Compound Fertilizer Rates on Growth and Flowering of Cocks Comb (Celosia argentea) Plants

“…On the other hand, the lowest number of leaves and branches per plant was found in plants grown in peat + sand (1:2) medium, this result was true in both seasons. Similar results were obtained by Riaz et al, (2014) and Sardoei and Shahdadneghad (2015) on Zinnia. In this respect, Dubey et al, (2013) concluded that soil + sewage sludge as growing media for petunia have high positive effect and significantly improved most vegetative growth character included number of leaves and branches per plant.…”

Standardization of Substrate Composition for Pot Plant Production of Tuberose var. Arka Sugandhi

“…Addition of organic manure to the inert substrate is essential to supply nutrients to the plants (Khan et al, 2006). According to Sardoei et al, (2014) selection of suitable media is essential for the flowering potted plants in order to improve the aesthetic value and marketing potential. Keeping in view the importance of substrates, the present study was conducted to standardize the growth, flowering and suitability of tuberose var.…”

Postharvest Quality of Cut Zinnia Flowers Cultivated Under Different Irrigation Levels and Growing Seasons

“…), species of the Asteraceae family of great potential in Brazil that presents an immense diversity of colors and petal shapes (Franzen et al, 2016), there are few studies about the longevity and postharvest characteristics of its flowers. Parameters such as density, porosity and water retention capacity of the growth substrate are known to influence the initial development of zinnia, and its floral quality (Pê go et al, 2019;Sardoei et al, 2014). As regards the influence of irrigation management, Heidari et al (2016) illustrated that growing plants under low water availability in arid or semi-arid climates leads to a decrease in the postharvest durability of zinnia flowers, cv.…”
