INFLUENCE OF PRE WATER SOAKING OF CORM AND FOLIAR APPLICATION OF MICRONUTRIENTS ON GLADIOLUS PRODUCTION

Abstract

The experiment was conducted in the Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, during October, 2013 to March, 2014. The experiment consisted with two factors. Factor A: Pre soaking of corm with water such as, W 0 ; No pre soaking (control), W ; Pre soaking with normal water and W 2

ii 1 ; Pre soaking with hot water and Factor B: Foliar spray of micronutrient as, F 0 ; No foliar spray (Control), F ; Foliar application with 0.25 % Boron and F 2 1 ; Foliar application with 0.25 % Zinc. The experiment was laid out in Randomized Complete Block Design with three replications. Highest number of floret spike -1 (11.3) and corm yield (8.8 t ha -1 ) was recorded from W 2 and lowest number of floret spike -1 (8.6) and corm yield (5.7 t ha ) from control. For foliar spray of micronutrient, highest no. of floret spike (11.0) and corm yield (8.6 t ha -1 ) was recorded from F 2 -1 -1 and lowest no. of floret spike

(8.8) and corm yield (5.6 t ha -1 ) from control. For interaction effect, highest number of floret spike -1 (12.7) and corm yield (10.6 t ha -1 ) was recorded from W W 2 0 F F 2 0 and lowest no. of floret spike -1 (7.7) and corm yield (4.3 t ha . From the above result it may be concluded that combination of pre soaking of corms with hot water and foliar application of 0.25 % Zinc attribute to more floret and corm yield.
