Abstract
ABSTRACT
An experiment was conducted to evaluate the economics and profitability of carnation
(Dianthus caryophyllus L.) production influenced by planting dates and cultivars. Three
commercial carnation cultivars, viz. ‘Dumas’, ‘Kiro’ and ‘Master’ and seven planting dates
starting from 15th October to 15th April at monthly intervals were undertaken in split-plot
design for investigation at the Department of Floriculture and Landscape Architecture, Dr.
Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan. The cultivar
‘Dumas’ was found to be most profitable over ‘Kiro’ and ‘Master’ with maximum plant
height (83.18 cm), stem length (78.70 cm), bud length (34.93 mm), bud width (21.55 mm),
maximum flower diameter (8.29 cm), number of cut flower stems per plant (7.04) and cut
flower stems per meter square (175.87). April 2015 planting showed maximum plant height
(88.57 cm), stem length (84.00 cm), bud length (42.05 mm), number of cut flower stems per
plant (7.19), cut flower stems per meter square (179.74) and duration 34.52 days). Highest
gross returns were obtained from cultivar ‘Dumas’ (Rs. 210856.70/500m2) when planted in
the month of April 2015 followed by March 2015 (Rs. 206801.50/500m2) planting of the
same cultivar. The cultivar ‘Dumas’ resulted in maximum benefit cost ratio of 4.05:1 and
4.16:1 respectively. The March 2015 planting was identified as the best planting time over
other plantings with highest cumulative returns to produce desired quantity and quality
flowers to meet the growing domestic as well as international demand.
