EFFECT OF TIME AND IBA CONCENTRATION ON THE PERFORMANCE OF BAY LEAF LAYERING

The experiment was conducted in a factorial Complete Randomized Design (CRD) with six levels of IBA viz. 1000, 2000, 3000, 4000, 5000ppm and control (without IBA) with five times of layering in the middle (15th) of each April, May, June, July and August at the Regional Spices Research Centre, BARI, Gazipur during May 2017 to September 2018. Bay leaf layering was found very much unsuccessful with or without IBA treatment. Layering time and IBA concentration significantly influence on the success and rooting of layers under Bangladesh condition. May to July layering with 4000 ppm IBA treatment found better for successful air layering for vegetative propagation of bay leaf in Bangladesh.
