Studies were conducted to standardize the agronomic practices for the production of quality roses under naturally ventilated polyhouse in the mid hills of Himachal Pradesh. Thirteen combinations of agro-techniques viz., growing media combinations (Soil: FYM: Sand/Cocopeat/Sawdust,); soil moisture regimes (20 kPa and 40 kPa); nutrient sources (Soluble/Straight/biofertilizers), growth regulators (GA3 and BAP) and plant architecture management ( pruning and bending ) were tested and replicated thrice. Result of the study revealed that growing media containing Soil: FYM: Sawdust (2:1:1 v/v) fertilized with water soluble fertilizer (150 ppm N and 200 ppm K), spraying of polyfeed (2g/l) at monthly interval from September-January and plant bending 6 weeks after planting was found to be the best treatment to enhance the floral quality parameters under protected conditions.
