Field performance of tuberose cultivars for growth, floral and economic characters under sub-humid southern plains and Aravalli hills of Rajasthan

摘要

The present investigation was carried out at AICRP on Floriculture, Horticulture Farm, RCA Campus, MPUAT, Udaipur to find outfield performance 13 tuberose cultivars with respect to growth, floral and economic parameters. The maximum values for plant height (91.67 cm), leaves plant~(-1)(43.50), bulbs plant~(-1) (50.0), bulb weight plant~(-1) (727.50 g), spike length (74.90 cm), peak flowering duration (21.83 days), vase-life in plain water (7.83 days), spikes plant~(-1) (3.02), florets spike~(-1) (53.17), florets remaining open at a time (6.17), floret size (4.73 cm), spike weight (118.30 g), net returns (Rs. 5,60,514/-) I ha and benefit: cost ratio (Rs. 2.69) were recorded in cv. Prajwal followed by Phule Rajani in single type cultivars. However, indouble type tuberose cultivars tallest plant (85.67 cm), leaves plant~(-1) (42.33), bulbs plant'1 (48.67), bulb weight plant~(-1) (739.50 g), spike length (75.62 cm), peak flowering duration (32.92 days), vase life in plain water (7.57 days), spikes plant~(-1) (2.90), florets spike~(-1) (49.83), florets remaining open at a time (6.83), floret size (4.58 cm), spike weight (109.33 g), net returns (Rs. 5,21,292/-) I ha and benefit: cost ratio (2.52) were obtained in cv. Suvasini followed by Vaibhav. On the basis of observations recorded for growth, floral and economics parameters cv. Prajwal in single and Suvasini in double type of tuberose recommended for cut flowers and exhibition purposes under Udaipur conditions.
