 ABSTRACT

The present investigation on “Effect of plant growth enhancers on growth, flowering and yield of tuberose cv. Prajwal” was carried out at Floriculture Research Farm, ACHF, NAU, Navsari, Gujarat during the year 2017-2018. The experiment was laid out in a Randomized block design with three replication and thirteen treatments comprising four growth enhancers viz., enriched sap of banana pseudostem (@ 5000, 10000 and 15000 ppm), brassinosteroid (@ 0.25, 0.50 and 0.75 ppm), GA3 (@ 50, 100 and 150 ppm), BA (@ 50, 100 and 150 ppm) along with control (no spray).The treatments were applied as foliar spray at 60, 90 and 120 days after sprouting of bulbs.
The experimental results revealed that foliar spray of enriched sap of banana pseudostem at 15,000 ppm (T4) was found best with respect to all the growth & flowering parameters in terms of maximum plant height (74.8 cm), more number of leaves (70.20), greater leaf area (65.20 cm2), minimum days to both rachis emergence (37.53 days) and floret opening (7 days), maximum length of spike (103 cm) and rachis (27.2 cm), more number of florets per plant (42.93), longevity of spike (12.73 days) and vase life (11.20 days). Similarly, yield attributes viz. number of spikes per plant (2.67) and per hectare (2.77 lakh), bulbs per plant (2.60) and per hectare (2.70 lakh were also found higher in T4. In case of chemical attributes, maximum chlorophyll content (1.09 %) and essential oil (0.23 %) were also recorded in the same treatment.
Keywords: Tuberose, banana pseudostem sap, brassinosteroid & BA.
