Abstract
A field experiment was conducted during 1994 at CPCRI, Kasaragod in open field to study the performance of WCT coconut seedlings grown in polybags and cement tanks with different media in comparison of conventional field nursery. The germination was highest in cement tank with coir dust medium (72.50%) as compared to sowing in polybag with soil (58.50%), and conventional method at 5th month (60.75%). The growth characters such as seedling height, number of leaves/seedling, and girth at collar were also superior at 9th and 12th months in cement tank with coir dust, followed by sowing in polybag with coir dust as compared to conventional nursery. Drymatter production above ground was significantly higher in polybag with coir dust (166.18g/seedling), and cement tank with coir dust (150.78 g/ seedling) compared to rest of the treatments. The number of roots/seedling was significantly higher in polybag with coir dust (16.0) compared to conventional nursery (6.75), cement tank with soil (9.25) and germination bed planting in nursery (10.0). The final recovery of vigorous seedlings was significantly higher in cement tank with coir dust (65.0%) followed by polybag with coir dust (58.75%) compared to conventional nursery (42.5%). Considering the advantage of reduced transplanting shock at field, raising coconut seedlings in polybag with coir dust may be preferred.
