“…Hence, clustering the seed nuts with space of 5 cm between them is good enough to save space and other resources. This finding is in line with that of Eufemia andRebecco 1980 andPeries, 1984 which stated that germination rate and cost of raising coconut in the nursery was different at 25 × 25 cm from those planted with spacing of 40 × 40; 60 × 60 and 80 × 80 cm. There was significant difference in the germination parameters between the sorted and unsorted seed nuts.…”

Cultivation of coconut is deterred by unavailability of improved planting material. Reducing the quantity of un-germinated seed nuts will optimize nursery space as well as increase seedling production per cycle. The experimental design was randomized complete block with two treatments at two levels each and four replicates. Four hundred seed nuts were randomly selected while the remaining Four hundred were selected by sorting. The seed nuts were arranged in the seed beds in two treatment pattern “spaced” and “cluster” sowing methods with spacing of 30 cm by 30 cm and 5 cm by 5 cm, respectively. There was no significant difference between the spacing methods tested. As much as spacing is between 5 and 30 cm, the germination rate will be similar in ground bed nursery. There were differences in the germination parameters between the sorted and unsorted seed nuts. Sorting had significant effect on seed nut emergence 59.38A and 42.38B; p<0.05 for the unsorted and sorted, respectively. The number of days to emergence and germination was significant at 10% (84.50A; 72.72B), 25% (101.25A; 90.63B), and 50% (126.50A; 110.38B) for the unsorted and sorted respectively. The significant negative correlation coefficient (–0.56, p<0.05) between 50 and maximum germination (MGP) percentage indicated that sorted seed nuts attained 50% germination earlier than the unsorted ones. This will be effective in determining the duration of MGP percentage in the seed lots. Sorting before sowing is essential to ensure early germination of seed nuts and to achieve high germination percentage. It will as well save resources.

“…The long dry spell experienced during the germination period would have further enhanced the process of drying. In an early experiment where entry of water into husk was facilitated through partial slicing itpromoted the rate of germination (Peries, 1984) which supports this argument.…”

Different combinations of river sand, cow dung and coir dust were compared with the conventional polybag mixtures to study whether seed germination would be affected by the substitution of top soil with river sand. The seed nut germination at 20 weeks was significantly reduced in the sand substituted media, but the difference disappered by 24 weeks from laying. The lower rate of germination was also associated with a reduction of seedling vigour at 30 weeks, probably due to poor seedling nutrition. River sand could be used as an alternative to top soil, provided the nutritive status of the sand is improved and refinements are made to decrease its rate of drying.

“…The seed nuts were dipped in a 10% solution of Aldrin prior to laying to prevent termite attack. The beds were mulched with dry coconut fronds and irrigated once in three days during dry weather (Peries, 1984). Manual weeding was carried out at the onset of the dry weather.…”

“…In the current study, where the management of seed beds was maintained at optimum level, very little difference was obtained between sites except those due to the superiority of the source of nuts. Germination can be adversely affected by lack of water in the seed nut which is very likely to be aggravated in the absence of adequate watering (Wuidart, 1984;Peries, 1984). Remison and Mgbeze (1987) observed that the use of a mulch to conserve water in the coconut seed beds led to increased plant height, plant girth and dry matter yield.…”

Seedlings were raised in three, nurseries representing different agro-ecological regions, to. test whether growing seedlings exhibited adaptation to a particular environment. Seed nuts were also selected from agro-ecologically different regions. The T x T seed nuts from the Isolated coconut seed garden showed a faster rate of germination at all sites compared to Moorock seed nuts (from the North Western region) or Dehigahalande seed nuts (from the Southern region). The vigor of seedlings (a qualitative assessment based on the number of vigorous seedlings selected) was enhanced by a good soil water supply during the early nursery stages combined with a higher level of solar-radiation at the nursery site. There was no interaction between the source of seed nut and site of nursery indicating the absence of manifestation of ecological adaptation at the seedling nursery. The quality of the seedlings was enhanced by adequate soil water and high level of solar radiation on the nursery' beds. The subsequent performance, of these seedlings would have followed up after field planting to confirm the assumptions on adaptation discussed.
