ABSTRACT
The present investigation entitled, “Effect of planting dates on growth and
flowering of China aster” was carried out at the experimental farm of Department of
Floriculture and Landscaping, Dr. Y. S. Parmar University of Horticulture and Forestry,
Nauni, Solan (H.P) during 2012. The experiment was laid out in a Randomized Block Design
(factorial) consisting of 21 treatment combinations of seven planting dates viz., 6th April, 16th
April, 26th April, 6th May, 16th May, 26th May, 5th June and three varieties namely ‘Kamini’,
‘Shashank’ and ‘Violet Cushion’. Among different planting dates, D1 i.e. 6th April gave best
results for plant height (88.10 cm), plant spread (47.44 cm), number of flowering stems per
plant (7.91), number of flowers per plant (37.58), yield of flower cut stems per plot (158.10).
However, D7 i.e. 5th June gave best results for days taken to first flower bud formation
(94.49), days taken to first flowering (105.80), flower size (5.51 cm) and vase life (10.12
days). Among the varieties, ‘Kamini’ gave best results for plant height (83.87 cm), plant
spread (46.07 cm), number of flowering stems per plant (8.17), number of flowers per plant
(41.97), flower size (5.79 cm), yield of cut flower stems per plot (163.20). However
‘Shashank’ took minimum days to first bud formation (91.67) and minimum days to first
flowering (103.70). However ‘Voilet Cushion’ recorded longest vase life (10.14 days).
Hence, it is concluded that planting of China aster on 6th April gave best results for most of
the desirable growth and flowering parameters especially the ‘Kamini’ variety.
