Abstract

Studies were conducted to find out the suitable seednut size, sowing orientation and nursery area for the production of vigourous seedlings in coconut (Cocos nucifera L.) var. East Coast Tall. The results showed that the growth rate and collar girth were higher in larger size seednuts (801-1200 g), when compared with smaller nuts (501-800 g). Seednuts sown vertically with calyx end pointed upward orientation have registered higher germination and seedling vigour. Among the nursery areas, beds raised in mist chamber condition showed higher growth rate (2.20) and plant height (82.6 cm). However, the collar girth (7.8 cm) and number of leaves (3.4) were more in the nursery beds raised under open condition.
