Flower quality, yield and bulb production of different varieties of tuberose as affected by different planting time and geometry under Prayagraj agro-climatic conditions

A field trial sponsored by UPCST, Lucknow, with nineteen (19) varieties of tuberose and three (3) spacings were conducted in the Deptt. of Horticulture, SHUATS, Prayagraj, during 2018-2019 to find out the most suitable time of planting and plant geometry for flower quality, yield and bulb production. The experiment was conducted in Factorial Randomized Block Design with three replications. Among March and April planting time, March planting resulted in significantly higher no. of bulbs produced per plant as well as higher bulb yield (quintal) per hectare. Among the different plant geometry (20 x 30 cm2, 25 x 25 cm2, 30 x 30 cm2), spacing of 30cm x 30cm resulted in significant earliness in bud emergence, spike length, no. of florets per spike, floret diameter, floret length, duration of flowering, vase life and no. of bulbs produced per plant. However, spacing of 25cm x 25cm resulted in significantly higher bulb yield per hectare.
