dc.description.abstractABSTRACT The present investigation entitled, “Effect of planting dates and plant spacing on growth, flowering and seed production of Zinnia hybrida under mid hill conditions of Himachal Pradesh” was carried out at the Research Farm of the Department of Floriculture and Landscape Architecture, Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2018-19. The experiment was laid out in a Randomized Block Design (Factorial) using four planting dates i.e. 25th March 2018, 25th April 2018, 25th May 2018, 25th June 2018 and four levels of spacing viz., 20 x 15cm, 20 x 20cm, 20 x 25cm, and 20 x 30cm. The observations recorded were based on growth, flowering and seed parameters. The plants transplanted on 25th April resulted in maximum duration of flowering (57.29 days), number of seeds per plant (1197.12), seed viability (93.83%), and seed germination (83.73%) and also took minimum number of days (21.22 days) for visible bud formation as well as days taken to flowering (23.86 days). However, plants planted on 25th May resulted in maximum plant spread (30.97 cm), flower diameter (5.04 cm), number of seeds per head (44.71) and weight of seeds per head (104.69 mg). The maximum plant height (22.80 cm) and number of flowers per plant (32.19) was observed when plants are transplanted on 25th March. The plant spaced at 20 x 30 cm recorded maximum plant spread (29.98 cm), flower diameter (4.91 cm), duration of flowering (56.96 days), number of flowers per plant (29.18), number of seeds per head (43.24), number of seeds per plant (1248.09), weight of seeds per head (102.26 mg), seed viability (92.09%), seed germination (83.07%). A plant spacing of 20 x 15 cm resulted in maximum plant height (22.80 cm) and minimum days taken for both visible bud formation (22.23 days) and flowering (25.95 days). The interaction i.e. plants planted on 25th April with spacing 20 x 30 cm resulted in prolonged duration of flowering (61.70 days) and also attained maximum number of seeds per plant (1429.87) with great seed potential viz. viability (94.97%) and germination (85.04%).en_US
