Different Pruning treatments in Rose

1. OUTLINE OF RESEARCH WORK On EFFECT OF PRUNING LEVELS AND GA3 ON GROWTH, YIELD AND QUALITY OF ROSE cv. DIVINE BHUTE PRAVIN NANDKISHOR PHD22-FLA-2620 Ph.D. 2 nd Year (Floriculture & Landscaping) WELCOME

2. ADVISORY COMMITTEE 1. Dr. D. M. Panchbhai Chairman 2. Shri. N. S. Gupta Member 3. Dr. Manisha Deshmukh Member 4. Dr. N. V. Kayande Member 5. Shri. R. D. Walke Member

3. OBJECTIVES To study the effect of different levels of pruning on growth, flowering and yield of Rose cv . Divine. To study the effect of GA3 on growth, yield and quality of Rose cv . Divine. To standardize the pruning level and GA3 concentration for better yield and quality of Rose cv . Divine.

4. EXPERIMENTAL DETAILS Crop : Rose ( Rosa hybrida ) Family : Ros aceae Year : 2024 and 2025 Design : Factorial Randomized Block Design Treatment Combinations : Sixteen ( 16 ) Number of Replications : Three (3 ) No. of Plants Per Treatment : Six (6 ) Total No. of Plants : Two Hundred Eighty Eight (288 ) Date of Pruning : 15 th June 2024
