Effect of GA3 on Different Varieties of Rose for Growth and Yield

A field investigation entitled “Effect of GA3 on growth, yield and quality of different rose varieties” was carried out during Kharif season of the year 2016-2017 at Horticulture Section, College of Agriculture, Nagpur with the objectives to study the different rose varieties for growth, flower yield and quality parameters and to find out the suitable scented rose variety for commercial cultivation in Nagpur conditions. The experiment was laid out in Factorial Randomized Block Design with four treatments. The treatments were replicated thrice. The treatments are G1-control G2100ppm G3200ppm G4300ppm with varieties V1 Toro, V2 Double delight, V3 -Gladiator. The result of the present investigation indicated that, significantly maximum vegetative growth in respect of height of plant, branches plant -1 leaf area and internodal distance were recorded by variety Gladiator and maximum plant spread were recorded in variety Toro and GA3 200ppm. Similarly yield parameters, maximum yield plot -1 , yield ha -1 were recorded by variety Gladiator and GA3 200ppm.Thus, it can be inferred from the present investigation that, the variety Gladiator and GA3 200ppm was found to be better in respect of vegetative growth and yield and parameters for commercial cultivation under Nagpur conditions.
