A trial was conducted to observe the effect of various combinations of NPK on the performance of rose, during the year 1996-97. The data was recorded and analyzed for plant growth yield and quality attributes. The data recorded in this trail indicates that days to sprouting, number of branches per bush and days to flowering were non-significant. Whereas, all other parameters remained significant with different doses of NPK fertilizers. Maximum flowers per plant (20 Flowers), longest pedicle length (5.85 cm), largest flower size (8.08 cm) and maximum petals per flower (50.38) were recorded in T6 treatment viz. (20-00-12) gm of NPK per plant. Maximum flower duration (4.45 days) and flower vase life (3.08 days) were also recorded in the same treatment.
