EFFECT OF ORGANIC MANURE, INORGANIC FERTILIZER AND BIO-CONTROL AGENT ON YIELD AND QUALITY OF GLADIOLUS

Abstract

The present investigation was carried out to study the effect of organic manure, inorganic fertilizer and bio-control agent on yield and quality of gladiolus at the Floriculture Research Field, BARI, Gazipur from October, 2014 to May 2015. The single factor experiment consisted of eight treatments namely: T : Control (Recommended dose of fertilizer) (N I 200 P 50 K 150 S 30 B 2 Zn : Tricholeachate (5000 l/ha) + ¼ RDF, T 3 : Bokashi (3 t/ha) + ¼ RDF, T : Mustard oil cake (500 kg/ha) + ¼ RDF, T 5 : Trichocompost (3 t/ha) + ¼ RDF, T : Farmyard manure (5 t/ha) + Trichocompost (3 t/ha) + ¼ RDF, T : Poultry manure (5 t/ha) + Trichocompost (3 t/ha) + ¼ RDF and T 8 7 : Vermicompost (5 t/ha) + Trichocompost (3 t/ha) + ¼ RDF. The experiment was conducted in Randomized Complete Block Design with three replications. Application of organic manure, chemical fertilizer and bio-control agent showed significant variations on most of the parameters. Result revealed that early sprouting of corm (8 days) was recorded from treatment T 6 . The treatment T has taken the minimum period (68 days) for 80% spike initiation. The maximum length of spike (80.0 cm) and rachis (34.0 cm), number of florets/spike (16), number of spikes/ha (200000) was registered with the treatment T 8 7 . However, the highest number (2.5/hill) and weight of corm (60.0 g) and cormel per plant (20.0) was recorded with treatment T . So, application of Vermicompost (5 t/ha) and Trichocompost(3 t/ha) with ¼ RDF showed best result on yield and quality of gladiolus.
