Item Performance of senecio biafrae (oliv. & hiern) j. moore under varying light intensities and compost rates in Ibadan, Southwestern Nigeria(2019) Olubode, O.S.; Johnson, A.S.Solanecio biafrae is an underutilized indigenous vegetable in southwest Nigeria. It is usually found in shades of other tree crops. This study investigated growth of S. biafrae as influenced by compost application under different light intensities in Ibadan, Southwest Nigeria. The pot study was conducted twice at the Crop Garden of the Department of Crop Protection and Environmental Biology, University of Ibadan. Four levels of light intensities were examined under multiple layers of nets: Growth under four test light intensities of unshaded natural light (0 net), and three levels of shades (1 net, 2 nets and 3 nets) assessed under four levels (0, 10, 15 and 20 g/pot) of compost (ratio 3:1 Tithonia-Poultry waste) in a randomized complete block design with light intensity as Blocks. Growth and yield data were analysed using analysis of variance and post-hoc tests conducted with Fisher's LSD at 5% probability. Lowest light intensity resulted in increased number of leaves, from 7.75 to 15.50 at 4 WAT and 7.78 to 18.50 at 6 WAT. Application of 20 g/pot compost resulted in higher number of leaves, number of nodes, vine height, vine diameter, root and shoot dry matter of S. biafrae under reduced light intensities. Low light intensity in combination with increased compost rates enhanced growth performance of S. biafrae. Cultivation of S. biafrae is recommended using of Tithonia diversifolia compost at the rate of 20g/5kg soil under low light intensity for optimum yield.Item Phenology and rate of sprouting of launaea taraxacifolia (willd.) amin ex c. jeffrey in Ibadan, Oyo state, Nigeria(2020) Morakinyo I.; Olubode O. S.Launaea taraxacifolia, a locally consumed vegetable in Nigeria is becoming popular due to the medicinal and nutritional potentials. Information about its agronomical properties is scanty. This study aims to determine the phenology and sprouting behaviour in Ibadan, southwest Nigeria. Studies were conducted at the Crop Garden of Department of Crop Protection and Environmental Biology, University of Ibadan, Nigeria in wet and dry seasons of 2019. Eighteen experimental bags, arranged in completely randomized design, filled with 5 kg each of heat-pretreated soil, and 15 field plots (1 m x 1 m each) in randomized complete block design were used for phenology and rate of sprouting (RS) respectively. Cuttings of 10 cm long of wild rhizomes of Launaea taraxacifolia were nursed for two weeks and transplanted uniformly at one seedling per pot. Planting spacing of 0.25 m x 0.25 m, 0.25 m x 0.5 m, 0.5 m x 0.50 m, 0.45 m x 0.75 m, and 0.55 m x 0.90 m and replicated three times were used. Data obtained were analysed using Analysis of Variance. Significant means were separated using Fisher’s LSD at p<0.05.Launaea taraxacifolia attained 67 - 111.4 cm height at 12 weeks after transplanting (WAT), branching and bolting, flowering and seeds matured at 8, 10, 12 WAT respectively. The means dry weight at 12 WAT in dry and wet seasons were 5.82 and 15.59 g/plant/pot respectively. Multiple sprouting commenced at 2 WAT and maximum RS (3.25/week) was attained at 8WAT in both seasons. Spacing at 0.25 m x 0.50 m was the best. Launaea taraxacifolia phenologically established faster as a good biomass accumulator in wet season unlike dry season. Spacing 0.25 m x 0.50 m was more desirable for Launaea taraxacifolia as it allowed better proliferation
