Abstract
The present study was carried out to study the role of homobrassinolide (HomoBL) and salicylic acid (SA) on vegetative growth of groundnut (Arachis hypogaea., L.) wherein field experiments were conducted with foliar spraying of 2µM and 3µM HomoBL and 1mM and 2mM SA on 20th, 30th, 45th and 60th DAS (Days after sowing). Observations on vegetative parameters like root and shoot length, root and shoot fresh weights, root and shoot dry weights, foliage showed that application of HomoBL and SA were capable of successfully mitigating cadmium stress (100 µM) as well as enhancing the vegetative growth of groundnut.
