Abstract
The present investigation entitled “Response of chrysanthemum (Chrysanthemum morifolium
Ramat.) varieties to different covering material for off season flower production” was carried
out at Research Farm, Department of Floriculture and Landscaping, Punjab Agriculture
University Ludhiana during the year 2019-20 with the purpose to find out the suitable
covering material for off-season flower production in chrysanthemum. Five different varieties
namely Banglori Local, Yellow Delight, Reagan Emperor, Regan White and Nanako and four
covering material (viz. Tarpaulin, High Density Polyethylene, Black Satin Cloth, and 50%
Green Shade Net) along with natural photoperiod (control) were selected and the trial was
replicated thrice using Factorial Completely Randomized Design (FCRD). The results
revealed that among the different covering materials, the optimum plant height (47.05 cm),
plant spread (15.36 cm), number of flowers per plant (32.35), number of flower per shoot
(9.75), with least number of days required for peak flowering (140.13days), was recorded
under the treatment where plants were covered with HDPE (High density polyethylene)
which was found to be at par with covering material i.e. tarpaulin under which the number of
days to bud appearance (109.40 days), days to colour break stage (132.60 days), branches per
plant (3.40) and stem girth (5.42 mm) were recorded. Flowering was earliest in plants under
controlled photoperiod as compared to natural photoperiod which took (172.80 days) days for
peak flowering. Based on the study it can be concluded that HDPE was found to be the most
suitable covering material for off season flower production and among the varieties ‘Yellow
Delight’ performed better under controlled photoperiod conditions as compared to other
varieties and resulted in off season flower production in chrysanthemum.
