ABSTRACT
The experiment was conducted to study the effect of cocopeat and sphagnum moss on rooting, survival and growth characters of rooted air layer plantlets under open and polyhouse nursery in guava during 2008-09. It was found that Coco peat + sphagnum moss recorded maximum rooting percentage (85.00), number of primary (10.80) and secondary (22.44) roots, length of longest (10.78 cm), fresh (2.72 g) and dry (0.51 g) root weight, establishment percentage (83.33), number of leaves (6.67) at 45 days after transplanting (DAT) and (13.83) at 60 DAT and minimum (8.67) number of days for buds sprouts. Polyhouse nursery performed better than open field nursery in all the parameters irrespective of methods of layering with minimum (8.83) number of days for sprouting, maximum establishment percentage (82.22), number of leaves (7.89) at 45 days after transplanting (DAT) and (13.08) at 60 DAT .
