A field experiment was conducted to find out the response of integrated nutrient management on growth and flowering in rose. cv. Gruss-an-Teplitz. Treatment consisted of 50, 40, and 30 g/m2 NPK by chemical fertilizer (C.F.), 4 kg FYM + remaining required dose of NPK by C.F., 4 kg FYM + remaining required dose by C.F. +Azotobacter, 4 kg FYM + remaining required dose NPK by C.F. + Phosphate solubilising bacteria (P.S.B.), 2 kg poultry manure (P.M.) + remaining required dose of NPK by C.F., 2 kg poultry manure (P.M.) + remaining required dose of NPK by C.F. + Azotobacter, 2 kg P.M. + remaining required dose of NPK by C.F. + P.S.B. and control (without application of manure and fertilizers). These doses were applied at the rate of per m2. Experiment was laid out in a randomized block design with three replications. Among growth parameters, maximum leaf biomass and dry weight of leaves were recorded with 4 kg FYM + remaining required dose of NPK by C.F. + P.S.B. which was at par with all the treatment except control. Maximum number of II order lateral shoots/plant was recorded with 4 kg FYM + remaining required dose of NPK by CF. + Azotobacter. However, all the treatments were failed to exert any significant effect on the diameter of I order lateral shoots. Regarding flowering parameters, maximum number and weight of flowers/plant, diameter of flower and number of petals/flower was recorded with NPK (50, 40, and 30 g/m2) by chemical fertilizer. All these parameters were statistically at par with 4 kg FYM + remaining required dose of NPK by CF. + Azotobacter. However, maximum dry weight of flowers/plant was recorded with 4 kg FYM + remaining required NPK by CF. + Azotobacter. Maximum flower yield was recorded with NPK (50, 40, and 30 g/m2) by chemical fertilizers followed by 4 kg FYM + remaining required NPK by CF. + Azotobacter. Non significant difference was observed between these 2 treatments on all flowering and yield attributes. Therefore, half dose of chemical fertilizers can be saved by application of 4 kg FYM + remaining required NPK by CF. + Azotobacter.
