Abstract
An attempt has been made to study the effect of vitalizer (GA3) and nitrogenous fertilizer (urea) on growth and floral parameters in tuberose cv. Pearl Double. The experiment was conducted at Horticultral Research Farm, Department of Horticulture, C.C.S. University Campus, Meerut, consisting two levels of GA3 (100 ppm and 200 ppm) and two levels of urea (55 and 110 g/m2). There were 9 treatment combinations, replicated three times and laid out in factorial randomized block design. The results reveal that combined application of gibberellic acid and nitrogeneous fertilizer (urea) at different doses showed the beneficial effect in different growth and flowering attributes viz., days taken for bulb sprouting, plant height, number of leaves/plant, number of floret/spike, rachis length, spike length and floret length but delay in appearance of initial spike and opening of first florets. Earliest appearance of initial spike and opening of first florets was recoreded by the individual application of gibberellic acid at higher concentration(GA3 @ 200 ppm).
