Abstract

Different growing conditions with temperature and sunlight variation could vary in flower growth and quality of marigold. Plant growth and flowering characteristics are compared in three different conditions viz. plastic house, shade house and open field. Three varieties of marigold viz. Marvel Yellow, Marvel Orange and Marvel Garland with similar cultural practices were grown and observed. Each variety with 6 replications was grown in three different growing conditions. Plant height, leaves formation, length of leaves, number of days to flower, number of flowers per plant and post harvest analysis were recorded. Plant growth characteristics followed by flowering behavior were found significantly better in plants grown under plastic house. During post harvest experiment Marvel Garland variety grown under plastic house with wet post harvest treatment was found significantly better compared to other conditions.

Highlights

Different growing conditions result in varied climatic attributes in flower cultivation
The increment in plant height per week was significantly higher (p ≤ 0.05) in the plants growing inside the plastic house compared to the plants grown in shade house and open field (Figure 1)
Number of leaves formation per week was found significantly (p ≤ 0.05) higher in plants grown in plastic house and shade house compared to the open field in case of Marvel Yellow and Marvel Orange

Summary

Introduction

Different growing conditions result in varied climatic attributes in flower cultivation. The growing conditions followed by the commercial flower producers depend upon various factors including temperature and daylight. (2014) Effects of Growing Conditions of Marigold in Ilam District, Nepal. With increased growing day temperature higher leaf area along with earlier rate of flowering was observed in some earlier research [6]. Reduction of daylight duration is found to increase the flowering days of some species of ornamental plants [7]. Marigold is one of the most important flowers in the context of Nepal It has religious as well as cultural importance. To promote the growth of the marigold cultivation and production in Ilam, this research is conducted to find out the growing condition of marigold varieties which are commercially grown in Nepal
