The seasonality of Dacryodes edulis limits the availability of propagules. To forestall its extinction, the effects of different temperature regimes on 3 seed sizes of fruit were evaluated to assess the recoverability of seeds in terms of percentage germination and seedling growth. The percentage germination was 97 for fruit softened at 25 and 50 while 87°C for fruits softened at 0°C and 85% for fruits softened at 75°C and least were 35 for fruits softened at 100°C. Plant height was significantly tallest (p<0.05) at 25.8 cm for fruits softened at 50°C, plant girth was largest at 4.0 cm for fruits softened at 0, 25, 50 and 75°C and number of leaves and leaf area were 8.1 and 63 cm3 for fruits softened at 75°C. The seedlings large fruit performed better medium and small. The growth parameters of fruit softened at 100°C were most significantly depressed. It is therefore concluded, that different temperature regimes had effect on different percentage germination and on some growth parameters of the plant. However, it is recommended that fruits of Dacryodes edulis whose seeds are intended for planting should be softened at water temperature of between 50 to 75°C. |

The fruits of Dacryodes edulis are seasonal and the duration of fruit softening and sensory evaluation is unknown. The effect of different temperature regimes on 3 sizes of fruits were evaluated to asses the duration of fruit softening and sensory evaluation. The duration of fruit softened at 50, 75 and 100°C were 1.5±0.5 to 13.5±0.5 min were significantly the same (p = 0.05) and significantly different (p<0.05) from fruit softened at 0 and 25°C which took 900±100 to 1450±50 min to soften. The sensory evaluation was significantly best for fruits softened at 75°C, followed by 50°C. The large fruits performed better than medium and small fruits. The different temperature regimes had effect on duration of fruit softening and sensory evaluation. However, it is recommended that, fruits of Dacryodes edulis, which are intended for eating, should be softened at water temperature regimes of 50 to 75°C. |

The benefit of intercropping in the nursery is yet to receive the necessary research attention. Three experiments were conducted to determine the effect of intercropping watermelon at various spacings with citrus rootstock seedlings in the nursery. The yields of watermelon grown in mixture with the citrus seedlings, where significantly different. Watermelon suppressed the growth of weeds under all the cropping systems involving watermelon and the development of the companion citrus seedlings at very narrow spacing of 1x0.5 m and 1x1 m. The girth of citrus rootstock grown in such narrow spacings, were reduced significantly by about 24%. The intercrop of watermelon at 2 mx1 m consistently produced the best yields in the three trials, followed by 2x2 m and was followed by 4x2 m. Generally, these spacings did not affect the growth of the companion citrus seedlings. The study showed that intercrop at the spacings of 2x1, 2x2 and 4x2 m are beneficial and tolerable range of growing watermelon in association with citrus rootstock seedlings before budding. |

The benefit of intercropping in the nursery is yet to receive the necessary research attention. Two experiments were conducted to assess the effect of intercropping seed melon at various spacings with citrus rootstock seedlings in the nursery. The intercropped seed melon did not affect the growth and development of the companion citrus seedlings at various patterns of planting melon. The citrus rootstock seedlings grown alone or intercropped with melon, produced plant girth, which ranged from 0.53 to 0.57 cm and 0.84 to 0.99 cm at 14 and 28 weeks after planting citrus in the nursery, respectively. The yields of seed melon grown in mixture with the citrus seedlings were significantly different. Melon suppressed weeds more with closer spacings of sowing and produced significantly lower weed spectrum and weed rating than sole crops of citrus seedling. The study showed that intercrop of melon at the spacings of 2x1 m, 2x2 m and 4x2 m used in this study are beneficial and tolerable for growing seed melon in association with citrus rootstock seedlings before budding. |
