PLANT DENSITIES AND CHLOROCHOLINE CHLORIDE ON GROWTH PRODUCTION AND ShELF LIFE OF GLADIOLUS

Abstract

The study was conducted at the Horticultural Farm of Sher-e-l3angla Agricultural University, Dhaka, Bangladesh during the period from October. 2007 to June. 2008 to find out the effect of spacing and concentration of Chlorocholinc Chloride (CCC) on growth, production and shelf life of gladiolus. The experiment consisted of two factors. Factor A: Three levels of plant densities i.e S,: 25 cm x 15 cm; S2: 25 cm x 20cm and S 3 : 25 cm X 25 cm and Factor B: Four levels of Concentration of CCC i.e C O : 0; C1 : 200; C 2 : 400 and C 3: 600 ppm respectively. The experiment was laid out with Randomized Complete Block Design with three replications. In case of plant densities the highest flowering plant (93.67%), yield of corm (17.06 tilia) and cormel (14.08 tlha) was recorded from S2 and the lowest from S1. In case of CCC the highest flowering plant (93.89%). shelf life (15.78 days), cormel per plant (22.54), yield of corm (16.20 L/ha) and cormel (14.40 t/ha) was recorded from C. and the lowest from C o . For interaction effect, the highest flowering plant (98.33%). shelf life (16.67 days), comicl per plant (25.02), yield of corm (18.21 r/ha) and cormel (16.23 lJha) was recorded from S2C2 and the lowest from SICI). The highest benefit cost ratio (2.21) was obtained from the combination of S 2C2 . So, it may be concluded that 25 cm x 20 cm plant density with 400 ppm CCC is suitable for growth, production and shelf life of gladiolus.
