Item Diallel Analysis of Sweet Potato [Ipomoea batatas (L.) Lam] Genotypes for Combined Beta Carotene and Dry Matter Content in Southern Guinea Savanna, Nigeria(Journal of Agriculture and Ecology Research International, 2019-07-26) Afolabi, M. S.; Bello, O. B.; Agbowuro, G. O.; Aremu, C. O.; Akoroda, M. O.Roots of orange-fleshed sweet potato varieties currently available in Nigeria contain high quantities of β-carotene or pro-vitamin A but have high moisture content. These varieties have been found to be a cheap and crucially important remedy for vitamin A deficiency. The cream or white-fleshed varieties, on the other hand, have a sweet taste with high dry matter content, giving a dry texture, a quality trait preferred in Nigeria. Development of sweet potato genotypes that can combine these two important quality traits is the objective of this breeding work. A diallel experiment using six parental sweet potato genotypes crossed in all possible combinations were carried out and thirty progenies were evaluated for beta carotene (β-carotene) and dry matter content in Landmark University, Omu Aran, Kwara State, Nigeria. The 30 F1 progenies along with their parental lines were planted in the same field trial. The trial was laid out in 6 x 6 triple lattice in two replications. Highly significant (P≤ 0.01) differences were observed among the genotypes for the traits. The average β-carotene content among the progenies was 2.86 (mg/100g.f.w) while the dry matter cttgontent had a mean value of 31.89%. The cross progenies 199024.2 x Excel had the highest beta carotene (14.37mg/100g.f.w) content with the highest dry matter content (40.10%) and are therefore recommended for further evaluation.Item Ethnoveterinary practice used for treating ruminant diseases in Ilara-mokin, Ondo State(Journal of Animal Science and Veterinary Medicine, 2020-12) Bada, A. A.; Adewole, S. O.; Agbowuro, G. O.The study investigated ethno-veterinary practice being used in treating small ruminants’ diseases in Ilara-mokin area of Ondo State. Structured questionnaires were used in the study area to collect primary data. Twenty-one people were randomly selected from different areas of Ilara-mokin which included Golf community, central market, central health centre, Iloro, petrol station and Baale central and Abbattoir. Different medicinal plants which include Ocimum gratissimum, Crested Cockscomb, Chromolaena odorata, Elaeis guinensis, Momordica charantia, Vernonia amygdalina, Nicotiana tabacum and Zingiber officinale were identified to treat ruminant diseases. The diseases were categorized based on environmental or microbial diseases. Pest identified in the study area was mite that caused mange. Indigenous knowledge was been practiced in the village and there is need for conservation of the specie of ruminant that is going into extinction and medicinal plants used within the town.Item PHENOTYPIC VARIABILITY AMONG AFRICAN YAM BEAN LANDRACE ACCESSIONS FROM DIFFERENT AGRO-ECOLOGIES OF NIGERIA(Nigerian Agricultural Journal, 2021-04) Agbowuro, G. O.; Salami, A. E; Aluko, M.; Olajide, O. O.The aim of this research work was to estimate the genetic variability and magnitude of the genetic components of some phenotypic traits among twenty African yam bean landraces collected from three agro-ecological zones of Nigeria. The accessions constituted the treatment which was laid out in a Randomized Complete Block Design with three replications. Accession seven performed best across the three locations in terms of grain yield, while accession ten had the least performance in term of grain yield. Levels of accessions and locations were significantly different (P<0.05) from one another for the studied traits except hypocotyl length, while accession x location interaction differed significantly (though at different levels) in all the traits except hypocotyl length, number of leaves per plant and pod length. The results revealed that phenotypic coefficient of variation were higher than genotypic coefficient of variation for the traits studied. Broad sense heritability estimates were high in all the studied traits. Genetic advance as percentage values were moderate to high for all the traits. High heritability estimate values coupled with high genetic advance in the research work depicts that improvement can be made on the crop through simple selection. This study provides baseline information for improving African yam bean landrace.Item Rice Blast Disease (Magnaporthe oryzae): A Menace to Rice Production and Humanity(International Journal of Pathogen Research, 2020-06-22) Agbowuro, G. O.; Afolabi, M. S.; Olamiriki, E. F.; Awoyemi, S. O.Rice blast disease is one of the major constraints to rice production, threatening food security globally. Rice grain production losses due to the disease leads economic losses to the farmers, and to an increase in global rice price as a result of the supply that is far below the consumer demand. The losses from the disease annually was estimated to feed over 60 million individual. The disease has been studied comprehensively by researchers due to the importance attached to rice and its vast spread and destructiveness across the globe. A good understanding of the pathogen causing the disease, its life cycle and development, epidemiology, symptoms, management strategy will offer a good insight into the disease incidence and give an appropriate and effective decision-making in its management. Different control measures have been adopted managing the disease, including the use of resistant varieties. Integrated disease management strategies coupled with good agronomy practices are required for successful control of rice blast for food security. This review, therefore, examined the fundamentals of rice blast disease (Magnaporthe oryzae) and offered strategies to minimize the disease activities to ensure proper production and increase the supply of rice grains.
