Item An Assessment of the Use of Agrochemicals among Small-Scale Farmers in Esanland, Nigeria(2014-10-05) Eifediyi, E.K; Omondan, G.O; Takim, F.O; Animashaun, JItem Effects of Transplanting Age on Growth and Yield of Tomato Varieties commonly Brown in South-Western Nigeria(Horticultural Society of Nigeria, 2019) Modupeola, T.O; Takim, F.O; Akintoye, H.A; Olaoye, GItem Impact of Tillage Operation on the Fruit Yield of six Exotic Tomato Varieties on an Alfisol in the Southern Guinea Savanna of Nigeria(Nigerian Branch of International Soil Tillage Research Organisation., 2011-02-21) Olaoye, G.; Takim, F.O; Aduloju, M.OThree separate field experiments were conducted at the Teaching and Research Farm, University of Ilorin, Nigeria on an alfisol with low inherent fertility status to study the effect of two conventional tillage methods on yield of tomato (Lycopersicon esculentum) during 2006 normal and 2007 irrigation growing seasons. The conventional tillage treatments (Ridge: tractor ploughed, harrowed and ridged and Flat: tractor ploughed and harrowed) were used to assess the response of the varieties to four N-Fertilizer regimes (0, 30, 60 and 90 Kg N/ha), two different growing seasons (rainfed versus irrigation) and two moisture regimes (normal watering versus post-anthesis moisture deficit) respectively. Tomato yields were significantly influenced by tillage methods with planting on the flat producing a significantly higher fruit yield than planting on the ridge except under moisture deficient condition. Roma (check variety) significantly yielded higher than other varieties under both N-Fertilizer regimes and growing seasons while Periondonta was superior for fruit yield under moisture regime.Item INFLUENCE OF LAND USE INTENSITY AND WEED MANAGEMENT PRACTICE ON FIELD EMERGENCE, CHARACTERIZATION AND GROWTH OF WEEDS IN SOUTHERN GUINEA SAVANNA OF NIGERIA(Journal of Agricultural Research & Development, 2013-12) Takim, F.O; Fadayomi, O.; Amosun, J.O; Ekeleme, FThe effects of land use intensity and weed management practice on weed seedling emergence, growth and characterization of weed species were examined at Ilorin, in the southern Guinea savanna of Nigeria. The study was conducted on three pieces of land with known cropping history, laid out as randomized complete block design with split-plot arrangement and three replicates. The main plots consisted of two cropping systems (sole maize and no cropping in continuously cultivated maize field, sole cowpea and no cropping in continuously cultivated cowpea field and sole maize, sole cowpea and no cropping in natural fallow field) while the sub plots consisted of three weed control methods (chemical weed control, hand hoeing at 3 and 6 weeks after planting and no weed control). Annual broadleaf weeds were most prevalent across the trial fields and constituted above 60 % of the total weed population. Cleome vicosa L., Euphorbia heterophylla L., Passiflora foetida L., Tridax procumbens L., Fimbristylis littoralis Gaudet and Rottboellia cochinchinensis (Lour.)Clayton were prevalent at continuously cultivated fields, Pycereus lanceolatus (poir) C.B.Cl, Phyllantus amarus Schum & Thonn. and Mariscus alternifolus Vahl had high frequency of occurrence at the natural fallow fields while Cyprus tuberosus Rotth was prevalent in all the sampled fields. In all, the frequency of occurrence of weeds was high at the continuously cultivated fields. Land use showed a pattern of increasing weed density in response to increasing land use intensity. These results show that intensive land use increases weed problems on farmers’ fields. The implication of the result on weed management is discussed.Item Influence of planting date and weed management practice on weed emergence, growth, and yield of maize (Zea mays L.) in southern Guinea savanna of Nigeria(Journal of Agriculture and Biodiversity Research, 2012-05-17) Kolo E., E; Takim, F.O; Fadayomi, O.Field trials were conducted during the 2008 and 2009 growing seasons in Ilorin, southern Guinea savanna zone of Nigeria, to determine the effect of planting date and weed control method on weed infestation, growth, and the development of maize. The experiment was designed as a randomized complete block in a split-plot arrangement. Planting dates (2 July, 16 July, 30 July and 13 August) constituted the main plots, while weed management practices, which included a weedy check, two hoe weedings at 3 and 7 weeks after planting (WAP), one hoe weeding at either 4 or 5 WAP and a preemergence application of Primextra Gold(R) [a proprietory mixture containing 290 g/L of metolachlor (2chloro-N-(2-ethly-6-methly-phenly)-N-(2-methoxyl-1-methly ethyl) acetamide) and 370 g/L of atrazine (6chloro-N-ethyl-N’-(1-methylethyl)-1,3,5-triazine-2,4-diamine)], at 2.5 kg ai/ha were the sub-plot treatments. Weed seedling emergence (infestation) was affected by date of planting in an inconsistent manner, a higher number of weed species were encountered in plots established on the first planting date (2 July) while plots established on the last date of planting (13 August) had the least number of weed species. Date of planting and weed control practice significantly affected maize grain yield and 100-seed weight, grain yield declined with delay in planting date. Maize growth likely contributes to the crop having a distinct competitive advantage over weeds when planted in early July, compared with late July and August plantings.Item Pattern of field emergence of weeds in an arable field in the southern Guinea savanna ecology of Nigeria(Weed Science Society of Nigeria, 2013-11-04) Takim, F.O; Fadayomi, OItem Pattern of field emergence of weeds in an arable field in the southern Guinea savanna ecology of Nigeria(Weed Science Society of Nigeria, 2013-11-04) Takim, F.O; Fadayomi, OItem Physical and Biochemical Attributes of Seeds for Screening Cowpea Genotypes for Resistance to Cowpea Weevil (Callosobruchus maculatus (f.))(Obafemi Awolowo University, Nigeria, 2022) Bankole, F.A; Musa, A.K; Olaoye, G; Takim, F.O; Olajide, O.OCowpea weevil {Callosobruchus maculatus (F.)} is an important field-to-store pest responsible for post-harvest loss of cowpea {Vigna unguiculata (L.) Walp.} seeds. One of the most economical and environment-friendly ways of preventing losses from the beetle is through the use of resistant cowpea genotypes. Physical and biochemical attributes of seeds play a key role in conferring resistance to the pest. Therefore, seeds of twenty-three cowpea genotypes were assessed for resistance to weevil infestation, nutritional and anti-nutritional factors. Relationship between the resistance parameters and the biochemical components of the seeds were also examined with the use of correlation analyses. Results showed that variability existed among the cowpea genotypes for seed physical resistance parameters such as initial seed weight, residual seed weight, seed weight loss, number of damaged seeds and weight of undamaged seeds. Association of reproductive efficiency with carbohydrate content, crude fibre and moisture content in the cowpea was positive and significant (r = 0.43*, 0.45* and 0.73**) while its relationship with protein content was negative and significant (r=-0.46*). The ash content correlated negatively and significantly (r=-0.46*) with the median developmental period. Cowpea genotype IT08K-125-107 exhibited the highest degree of tolerance to C. maculatus infestation, having suffered neither weight loss nor damaged seed and also had very low reproductive efficiency of the C. maculatus. The study concluded that while biochemical components played very little role in conferring resistance to C. maculatus in cowpea, increased carbohydrate content, crude fibre as well as reduced ash and protein content in the cowpea seeds decreased the reproductive efficiency and intensity of the C. maculatus infestation.
