Title: Effect of Bed type and Spacing on Growth Characteristicsand Oil content of Basil Plant ( Ocimum basilicum L.)
Author: Azza Osman Kobur
Abstract: This experiment was conducted to study the effects of using different bed types and plant spacing on growth characteristics and oil content of Ocimium basilcum (Basil) plant. Two bed types (flat & ridge), and three different spacing (30, 45 and 60cm.) were used. Growth characteristics were evaluated in terms of plant height, number of branches, fresh and dry weights of leaves and root length. Leaf samples were collected for determination of oil content. All these parameters were recorded after 45, 60, 75 and 90 days from planting. Results revealed that plant height measurements tended to vary depending on the time in which these measurements were recorded. Greater values of plant height were associated with plants grown on flat than those grown on ridge. Closer spacing (30cm.) was noted to result in greater values of plant height compared to the rest of the spacing. The combination of closer spacing and flat bed or ridge resulted in greater values of plant height than the other combinations. Similar pattern was noted with the measurements of root length. Planting basil plants on ridges at wider spacing (45 or 60cm.) resulted in greater values of number of branches compared to the other combinations. The differences in the values of both fresh and dry weights of leaves were not significant among combinations: however, growing plants on ridge at a wider spacing (60cm.) gave greater values compared to the rest of the combinations. The differences in the oil content between growing plants on flat bed and ridges were not significant; however, greater values were associated with ridge method of planting. Significantly greater oil content was detected in plants grown at spacing of 45 cm compared to the other two spacing. No clear trend was noted on the values of oil contents using different combinations. Generally, the greater oil content was detected in leaf samples collected after 75 days from planting compared to the other times of sampling.
