Abstract

A field experiment was carried in a Factorial Randomized Block Design (FRBD) with three replications, comprising of 12 treatment combinations. The results indicated that the important growth characters were significantly influenced by pinching and application of growth retardants than spacing tried under this investigation. The treatment combination S2P1G1 i.e., T11 was found to be superior and recorded more number of flower spikes per plant (11.13) at 75 DAT, maximum length of spike (21.48 cm), maximum florets per spike (82.40), maximum length of florets (1.90cm) and maximum flowering duration (97.06 days). The treatment combination S2P1G1 i.e., T11 (25 cm × 25 cm spacing + pinching + CCC@500ppm) was found to be superior for flowering characters in salvia.

Conclusion

Based on the results obtained spacing did not show significant effect for most of the parameters. However, pinching and application of growth retardants particularly cycocel produced pronounced effect on flowering behavior of salvia plants. Pinching helped increased flower production. Likewise, application of growth retardants resulted in delayed flower bud initiation due to suppression activity of growth retardants. Hence, from the present experiment it can be concluded that the treatment combination S2P1 G1 i.e., T11 of spacing 25 cm × 25 cm + pinching + CCC@500 ppm was found to be best for most of the flowering parameters including number of flower spikes per plant (7.16), length of the spike (21.48), number of florets per spike (82.40) and delayed flowering duration (97.06 days) in salvia.
