The botanical name combines the Latin word tuberosa, which means “swollen root,” or tuber, with the Greek word polianthes, which means “multi-flowered”. The flowers are important in the flower market because they keep their freshness for a long time and endure long distance transportation. In light of all these, the present study was undertaken to investigate the response of plant height of tuberose, spike length, rachis
length and number of flowers per spike. The results demonstrated that the time of planting had a substantial
influence on the plant height and spike length of tuberose plants i.e. every delay in planting reduced plant
height, regardless of genotype. During both the years, the greatest plant height was seen in March planting
(84.48 and 76.20 cm), while the shortest was reported in May planting (76.64 and 68.32 cm). The results also
showed a considerable impact of different genotypes and planting time on rachis length, with different genotypes and planting time delayed greatly increasing rachis length in tuberose throughout the years 2019-
20 and 2020-21. During both the years, the Mexican Single (46.96 and 42.47) genotype had the most florets
per spike, while the Hyderabad Double (22.11 and 16.22) had the fewest.
