    Growth and Yield of Sesame (Sesamum Indicum L.) as Influenced by Combinations of Varying Levels of Nitrogen and Foliar Fertilizers
    (2020-11) A.I. Afe; S.K. Ogundare; K. Fasakin
    Purpose: Various foliar fertilizers are used alone or in combination with soil-applied inorganic fertilizers in Nigeria to increase crop growth and yield. Information on the mixture of foliar fertilizers and soil-applied nitrogen on sesame is scanty. This study investigated the growth parameters of sesame under the various combination of foliar fertilizer with nitrogen. Materials and methods: Five levels (0, 20, 40, 60, and 80 kg N/ha) of nitrogen were combined with three foliar fertilizers (Maxiforce, Supergrow, and Plantzyme) using a 3 x 5 factorial in a complete randomized block design and replicated three times. Results: The nitrogen levels significantly influenced the number of leaves produced, leaf area, number of pods per plant, and seed yield. There were no significant effects among the foliar fertilizers on the growth and yield of sesame. Application of super grow in combination with 60kgN was appeared promising. The results of the study showed that mixing foliar fertilizer with nitrogen was found to improve the growth and yield of sesame

    LEAF YIELD AND NUTRITIVE VALUE OF BUNGU (Ceratotheca sesamoides Endl.) and BLACK SESAME (Sesamum radiatum Linn.) AS INFLUENCED BY AGE AT HARVEST IN THE SOUTHERN GUINEA SAVANNA ECOLOGICAL ZONE OF NIGERIA
    (2018) K. Fasakin; J.A. Olofintoye; A.I. Afe
    Overall yield and the nutritive value of harvested leaves of bungu and black sesame at weekly interval were determined. The objective was to provide useful information for market gardeners and consumers. Field experimental plots, each 1 x 2 m in size, were laid out using 2 x 4 factorial structure in split-plot design with four replications and data collected at 7, 8, 9, and 10 weeks after planting (WAP). Detached plant leaves were subjected to proximate analysis in the laboratory. Means of two years’ results indicated that leaf and shoot yields per plant, and leaf-to-shoot ratio in the crop species were similar, but leaf and shoot yields per unit area of land were higher in black sesame (1.64kg and 5.35kg, respectively) than in bungu (0.97kg and 3.38kg, respectively). Generally, as age increased from 7 to 9 weeks, number and total length of branches, as well as number of leaves per plant also increased, and thereafter the increases were no longer significant. Leaf area per plant and leaf area index in the two crop species were similar between 7 and 9 weeks of age and thereafter declined. Based on the average of two years’ results, the highest leaf and shoot yields per plant (5.48g and 18.73g, respectively) and per m2 of land (1.49kg and 5.16kg, respectively) were obtained at 9 weeks of age. In terms of the nutritive value of the leaves, the levels of crude protein and total ash in black sesame and bungu leaves, respectively, were significantly higher at 7 weeks after planting (protein: 33.68%, 34.65%; ash: 10.75%, 13.00%) than at 8 weeks (protein: 28.55%, 28.50%; ash: 8.88%, 10.88%), 9 weeks (protein: 28.33%, 28.18%; ash: 8.88%, 10.00%), and 10 weeks (protein: 28.83%, 26.08%; ash: 9.00%, 10.63%). Considering both the quantity and nutritive value of leaf yield, 8 - 9 weeks after planting the crop appears to be the optimum age to harvest the leaves of the crop species for culinary use.
