Abstract

A pot culture study was carried out to investigate the allelopathic effect of mulching with fresh leaves of eight tree species viz., jack (Artocarpus heterophyllus Lamk.), mango (Mangifera indica L.), tamarind (Tamarindus indica L.), matty (Ailanthus triphysa Dennst.), wild jack (Artocarpus hirsuta Lamk.), teak (Tectona grandis L.f.), rubber (Hevea brasiliensis Mull. Arg.) and panal (Glycosmis pentaphyllus Retz.) on growth and yield of ginger (cv. Karthika). Mulching with mango and tamarind leaves adversely affected growth and yield of ginger. Rhizome yield was significantly less when mulched with mango (521 g plant-1) and tamarind (512 g plant-1) leaves which was a consequence of the significantly lower plant growth, tiller production, leaf production, root length, root spread, rhizome spread, rhizome thickness and stomatal conductance in ginger. However, mulching with all the other tree leaves gave significantly high rhizome yield. An interesting observation was that in the control where newspaper was used as mulch, the yield was high (637 g plant-1) and comparable to mulching with panal, rubber, teak, matty, wild jack and jack leaves.
