Standardization of Different Growing Environment Conditions for Button Rose

An investigation on Standardization of different growing environment conditions for button rose was carried out at Floriculture Research Station, Thovalai, Tamil Nadu during the year 2017-18 in randomized block design with five treatments of growing condition. The result revealed that, the significantly influence in button rose, the treatment T3 (35% shade net only as top cover) recorded the highest plant height (53.38 cm), number of shoots / plant (7.00) and number of flowers in a cluster (9.75). The same treatment exhibited the highest number of leaves (77.75), early flowering (18 days) and early bud initiation after previous flowering (14.75 days) which was on par with the treatment T5 (open condition) which recorded 76.50, 18.75 days and 15.00 days respectively at three months after planting. Among the treatments, the treatment T2 (50% shade net) recorded the lowest plant height (46.63 cm), number of leaves / plant (70.75), number of shoots / plant (3.50), number of flowers in a cluster (6.50) and delayed flowering (20.75 days) and bud initiation after previous flowering (20.00 days). In case of yield parameters T5- Open condition recorded maximum individual flower weight (1.06 g), Number of petals per flower (65.23) and Flower yield per plant / year (125.38g).
