A Media and Fertilizer Study in Anthurium1

Abstract

Abstract A study was conducted on Anthurium andreanum Lind, cv Ozaki Red testing sugarcane bagasse, wood shavings, black cinder, black cinder base with bagasse mulch, and tree fern chips, media and fertilizer levels of 448, 196, and 370 kg N-P-K/ha per yr at 1, 2, and 3 × rates. Media ranking from best to poorest for flower production, flower stem length, and flower size were: sugarcane bagasse, wood shavings, black cinder base with bagasse mulch, tree fern chips and black cinder. The low fertilizer rate gave as good or better results in flower production as the high rates. The 2 × rate produced slightly longer flower stems and larger flowers than 1 × or 3 × rate. Flower production decreased with age of plant, but both stem length and flower size increased.
