Effect of Fertigation, Micronutrients and Bacillus sp for Maximizing the Yield, Quality and Disease Management of Rose (Rosa hybrida var., Tajmahal) under Greenhouse Conditions

An experiment was conducted to study the effect of fertigation, micronutrients and bacillus sp to maximize the yield and quality of rose variety Tajmahal under naturally ventilated polyhouse. It consists of 22 treatments for the study, highly significant results were observed with respect to various plant parameters. Among the treatments, the plants of T₁₉ significantly recorded highest plant height (167.26 cm), plant spread (47.82 cm²), early flower bud appearance (26.93 days), minimum duration for harvest (49.08 days), increased stem length (83.77 cm), increased flower bud circumference (12.81 cm), flower stem girth (0.83 cm), increased number of cut flowers per plant (27.07) and extended vase life of 11.50 days inthe vase solution containing 100ppm Al₂SO₄ +1% sucrose. It is clear from the study that plant growth parameters, yield and quality of flowers were found to be superior in T₁₉ (125% of RDF @ 208:104:104 g NPK/m²/year + foliar application of 0.5% EDTA+ soil and foliar application of B. megaterium and B. amyloliqufaciens each@ 10 ml/m²) for the var. Tajmahal.
