Abstract

                                Investigations were carried out on spacing and optimum nutrition required for rose cv.Charisma at GKVK, Bangalore, in a factorial randomized complete block design with 12 treatment combinations comprising of three different plant densities viz., S1 (0.75 x 0.75 m), S2 (1.50 × 1.00 m) and S3 (1.80 × 1.00 m) and four levels of nutrients viz., N1 (202030 g NPK/plant), N2 (303045 g NPK/plant), N3 (404060 g NPK/plant) and N4 (505075 g NPK/plant). It was found that plant density S2 (1.50 × 1.00 m) and nutrient level N2 (303045 g NPK/plant) had showed superiorityin the flowering and yield attributes viz., early flowering (45.67 days), maximum number of flowers per plant (123.78), the highest yield per plant (0.83 kg), and maximum shelf life (39.72 hr). While, plant density S1(0.75 × 0.75 m) and nutrient level N1 (202030 g NPK/plant) recorded late flowering (50.67), minimum number of flowers per plant (85.92), the lowest total yield per plant (0.39 kg) and minimum shelf life (31.47 hr). Whereas, plant density S1 (0.75 × 0.75 m) and nutrient levels N4 (505075 g NPK/plant) recorded higher yield per hectare (10.83).
