Item Effect of soil amendments on growth, minerals and proximate composition of Lawmen taraxacifolia (Willd.) Amin Ex C. Jeffrey(2015) Morakinyo, I.; 0lubode, O. S.Launaea taraxacifolia is a rarely consumed vegetable in a few countries of Africa where it is cultivated. It is mostly restricted in range to the wild. It is indigenous and largely uncultivated in Nigeria due to cultural inhibition and lack of information on its dietary benefits. Knowledge of its minerals and proximate contents under various soil amendments would enhance its consumption in southwest Nigeria. Field assessment of response of L. taraxacifolia to soil amendments was carried out at Atiba Local government area (LGA), Oyo State, Nigeria in the rainy season of 2015. Number of leaves produced and mean leaf areas (cm2) of Launaea taraxacifolia to poultry manure, cattle dung at the rate of 2 t/ha and urea (200kg/ha) were assessed in a completely randomized design with five replicates. Data were analysed using analysis of variance. Means that were significant were separated using Duncan’s Multiple Range at ¥=§.05.Launaea taraxacifolia performed better on Urea fertilized plots better than in plots supplied other amendments and control. There was no significant difference in number of leaves and leaf area of Launaea taraxacifolia in plots amended with cattle dung or poultry manure. The vegetable had significantly (P<0.05) highest ash (2.30%), fat (2.10%), carbohydrate (77.62%) and energy content (338.38 Kcal/J) in plots amended with cattle dung. The study indicated that the perforamnee of Launaea taraxacifolia under synthetic and organic soil amendments was comparable.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
