Abstract
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.
Highlights
Bay leaf is a high valued spices having valuable aroma, higher nutritive and medicinal value widely used in Bangladesh for preparation of many kinds of foods, beverage, cosmetics and medicines

Summary
Bay leaf is a high valued spices having valuable aroma, higher nutritive and medicinal value widely used in Bangladesh for preparation of many kinds of foods, beverage, cosmetics and medicines. The quality of imported bay leaf is poor due to admixture, sub-standard processing and long storage and transport duration. Standard vegetative propagation technology of Bay leaf has not yet been standardized in Bangladesh. Effect of time and iba concentration on the performance of bay leaf layering. Effect of time and iba concentration on the performance of bay leaf layering of appropriate vegetative propagation techniques of Bay leaf for rapid dissemination of high yielding varieties (BARI Bay leaf-1) is essential to ensure quality bay leaf production. To increase bay leaf production, intensive research on propagation is very much essential in our country. The study is undertaken to standardize the propagation techniques using optimum strength of rooting hormone (IBA) concentration and layering time for rapid multiplication of bay leaf to ensure quality sapling production
