- ItemEFFECT OF PRILLED AND GRANULAR UREA ON THE GROWTH AND YIELD ON CUCUMBER (Cucumis sativus. L) CULTIVARS IN SOUTHERN GUINEA SAVANNAH, NIGERIA(2022) A.I. Afe; A.I. Ayodeji; T.O. Ajiboye; U.Y. IbrahimA pot experiment was conducted between March and July 2021 at the screen house of the Department of Crop Production, Kwara State University, Malete in the Southern Guinea Savannah agro-ecology, Nigeria to evaluate the response of cucumber cultivars to prilled and granular urea. The study consists of three cucumber cultivars (Basma, Pico and Pointset) and two forms of urea (prilled and granular urea) and the control laid out in a 3×3 factorial combinations in a completely randomized design replicated three times. Data were collected on the following variables: number of leaves, vine length, leaf area, days to 50% flowering and fruiting, fruit length and fruit circumference, and fruit yield/ha. Data were subjected to Analysis of variance (ANOVA) and treatment means where significant difference exist, were separated using Duncan Multiple Range Test at 5% level of probability. The control treatment significantly had shorter vine length at 4 and 6 weeks after sowing (WAS) compared to the granular and prilled urea application. Application of prilled urea was superior to granular urea on the vine length at 4 and 6 WAS. All the cultivars had similar leaf area at 8 WAS. There were no significant differences on days to 50% fruiting and fruit circumference among the three cultivars. The control treatment, however, took longer days to attain 50% flowering in Poinsett cultivar compared to other treatments. In addition, the control treatment also significantly had shorter fruit length, poor fruit yield compared to application of granular and prilled urea fertilizers. Application of prilled urea significantly produced higher fruit yield/hectare than granular urea in Basma and Pico cultivars. The least fruit yield/plant 5.00, 4.62, and 3.92 t ha1 respectively for Basma, Pico and Poinsett were obtained at the control treatment. Basma cultivar recorded the highest fruit yield (17.36 t ha-1 ) with application of prilled urea fertilizer and hence, recommended.
- ItemEffects of dietary Jatropha gossypiifolia leaves extract on growth performance, antioxidant capacity, immune response, and disease resistance of African sharptooth catfish (Clarias gariepinus) infected with Aeromonas hydrophila(Taylor and Francis, 2024-08-19) O.V. Adeniyi; M.R. Adedayo; A.I. AfeThis study investigated the effects of Jatropha gossypiifolia leaf extract (JGE) on the performance and immune response of African sharptooth catfish. Fish (6.43 ± 0.26 g, n = 450, 30/repli cate) were fed diets supplemented with 0, 0.5, 1.0, 1.5, or 2.0 g JGE/kg in triplicate for 84 days. Thereafter, the fish were injected with Aeromonas hydrophila and observed for 14 days. Fish fed 1.0–1.5 g JGE had higher (P < 0.05) weight gain, protein effi ciency ratio, and villi absorption area, with highest performance at 1.0 g JGE. All the fish fed JGE-supplemented diets had enhanced (P < 0.05) activities of glutathione-s-transferase and glutathione peroxidase, compared to fish fed control diet, while the variations in erythrocyte and leucocyte counts were insig nificant (P > 0.05). The post-challenge fish fed JGE- supplemented diets had higher lysozyme, phagocytic, and respiratory burst activities and survival than the control treatment
- ItemGrowth 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. FasakinPurpose: 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
