In this study the treatments consisted of NPK (50, 40 and 30 g/m2), half dose of chemical fertilizers (25, 20, 15 g NPK/m2) with various manures i.e., FYM (4 kg/m2), mushroom spent (4 kg/m2), poultry manure (4 kg/m2), FYM (4 kg/m2) + Azotobactor, FYM (4 kg/m2) + VAM, mushroom spent (4 kg/m2) + Azotobactor, mushroom spent (4 kg/m2) + VAM, poultry manure (4 kg/m2) + Azotobactor, poultry manure (4 kg/m2) + VAM and control (without application of manure and fertilizer). Bushes of rose cv. Gruss-an-Teplitz of five-year-old, having uniform growth and vigour were selected for study. Pruning was done on 15 October 2003, followed by wintering and manuring. Manures and bio-fertilizers were applied during pit filling except nitrogen. Half dose of nitrogen was applied at the time of pit filling and remaining dose was given after 30 day of pruning. Experiment was laid out in a randomized block design and replicated thrice. All the growth and flowering parameters except days taken to flowering after pruning were found statistically significant due to various treatments. Maximum diameter of shoot was observed with application of FYM (4 kg/m2) + NPK 25, 20, 15 g/m2 followed by mushroom spent (4 kg/m2) + NPK 25, 20, 15 g/m2. Maximum number of leaves/plant and leaf area index were exhibited with poultry manure (4 kg/m2 + VAM) followed by poultry manure (4 kg/m2) + NPK 25, 20, 15 g/m2 + Azotobactor application, whereas application of poultry manure (4 kg/m2) + NPK 25, 20, 15 g/m2 resulted in maximum number of IInd order lateral shoots. Maximum fresh weight of leaf was recorded with poultry manure (4 kg/m2) + NPK 25, 20, 15 g/m2 + Azotobactor. Early flowering was noticed in the treatment of farmyard manure (4 kg/m2) + NPK 25, 20, 15 g/m2 + Azotobactor. Same treatment also gave early flowering after first flush. It is interesting to note that maximum number of flowers/m2 during first, second and third flush was recorded with the application of poultry manure (4 kg/m2) + NPK 25, 20, 15 g/m2 + VAM. In general performance of poultry manure 4 kg + NPK 25, 20, 15 g/m2 + VAM was found to be better for plant growth and yield of flower, followed by poultry manure (4 kg/m2) + NPK 25, 20, 15 g/m2 + Azotobactor.
