Effect of staggered planting date on growth, floral, bulb and economic parameters in Phule Rajani tuberose under subhumid southern plains of Rajasthan

Abstract

An investigation was carried out during 2013 and 2014 to find out an effect of staggered planting date on growth, floral, bulb and economic parameters in tuberose cv. Phule Rajani. The treatment comprised with various staggered planting dates viz. 15th April, 30th April, 15th May, 30th May, 15th June and 30th June at 15 days interval. Out of six staggered planting treatment P1- 15th April were found significantly superior for leaves plant-1 (31.09), plant height (66.81 cm), spike length (59.94 cm), days to spike emergence (111.03), days to flower bud break (122.03), floret spike-1 (35.72), durability of spike (9.36 days), spike plant-1 (3.78), spike weight (72.12 g), bulb weight plant-1 (173.89 g), bulbs plant-1 (6.87, 16.43), gross return (` 680539 ha-1), net return rupees (` 469506 ha-1) and benefit / cost ratio (3.01) with highest trends in this planting which was found better over other staggered planting dates. Therefore, on the basis of two year study, it may be concluded that staggered planting from 15th April to 30th May can provide continuous supply of cut spike to market from tuberose planted field and resulted in ensure return to farmers.
