The higher level of N (80 g/m2) significantly increased number of leaves/plant, leaf biomass, leaf area, height of plant, number of flowers/plant, during various months and weight of flowers/m2/year, which were at par with 60 g N/m2 treatment. Plants receiving lower dose of N (20 g/m2) gave poor growth and lower yield of flowers. The split application of nitrogen failed to exert any striking effect on various growth and flowering attributes except number of leaves/plant and leaf area index on which three split application of nitrogen doses gave higher value which were at par with two split application of nitrogen. Therefore, it may be concluded that 60 g N/m2 and its two split application can be followed in rose cv. Gruss-an-Teplitz cultivation under tarai condition of Uttranchal.
