Effect of different GA3 concentration and biofertilizer on growth and flowering parameters of anthurium (Anthurium andreanum Lindex Ex Andre) cv. tropical in soilless culture

Abstract

An investigation was carried out during 2017-2018 to study the effect of GA3 and biofertilizer on growth and flowering parameters of Anthurium (Anthurium andreanum Lindex Ex Andre) in soilless culture in the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat, Assam. As a result, different growth and flowering parameters like the highest plant height (42.78 cm), highest number of leaves (9), highest leaf length (32.26 cm), highest leaf breadth (20.23 cm), highest leaf area (309.37 cm2), highest plant spread (29.23 cm), highest number of sucker per plant (3.67), highest number of flower per plant (14.33), spathe length (18.98cm), spathe breadth (13.43cm) and flower stalk length (42.27cm), highest self-life of spathe (52.20 days) and highest vase life of spathe (32.20 days) were found in treatment T3(Recommended dose of fertilizer i.e. RDF+ Azospirillium+ 100ppm GA3). Hence considering the positive effects on growth, flowering, yield and quality, T3 can be considered for adopting at the field level to reap good economic yield with better quality and high net return.
