Effect of rainfall and temperature distribution in Yewa North savannah and Onigambari rainforest zones of Nigeria on maize and cassava intercrop
(2006) Ndubuaku, U. M.,; Adejonwo, K. O.; Sosanya, O. S.; Fayinminnu, O. O.
This study was carried out in the savannah region of Ayetoro in Yewa North and the rainforest region of Onigambari in Ibadan North to determine the effects of rainfalland temperature distributions on the growth and yield of tropical Zea mays resistant variety with yellow flint (TZSR-Y) in the two ecological zones. The meteorological results showed even distributions of rainfall and temperature at Onigambari rainforest zone in 2004 and 2005 while those of Ayetoro savannah vegetation followed an irregular pattern. There was higher vegetative growth of the maize plants in terms of number of leaves, leaf area, stem height, number and length of internodes. The yield values such as the number and weight of grains per hectare were higher in Ayetoro than Onigambari. There were no significant differences in the moisture contents of the grains in both ecological zones.
Effects of dichlorvos (DDV P) on the haematological properties of wistar rats
(2015) Olaoye, S. O; Fadina, O.O; Fayinminnu, O. O.; Adedire, O. M.; Ogundipe, W. F; Fajobi, A. K.; Farinu, A. O
The potential sub-chronic toxicological effects of oral administration of Dichlorvos (DDVP) on wistar rats was investigated for a period of 6 weeks. Thirty-two (32) wistar rats (equal number of both sexes) were uniformly divided into two groups while each comprised of 4 divisions with four rats each, At the end of experiment, animals were sacrificed and heamatogical test was carried out to investigate the possible toxicological effects of the oral administration of the pesticide on the rats. Results generally showed a dose-pendant response with PCV, Kb, RBC and Plan values that are significantly different from each (P<0.05) among the male rats while PCV and RBC values are significantly different from each other (P<0.05) while all other heamatological parameters in both sexes showed no significantly difference from each other at P<0.05. This result suggests that ingestion of the pesticides (Dichlorvos) may not be toxic at the doses investigated
Efficacy and Gross margin analysis of carbofuran on nematode management in three cultivars of cowpea (Vigna unguiculata (L) Walp)
(Faman: farm management association of Nigeria, 2007) Sosanya, O. S.; Afolami, C. A.; Fayinminnu, O. O.
Field trials were carried out in 2000, 2001 and 2002 to study the efficacy of applying carbofuran at 0 kg a.iЛha; 2.4 kg a.i/ha; 3.0 kg aiha and 3.6 kg a.i/ha in the management of nematode populations in the production of three cowpea cultivars: Ife Brown, JT90K- 277-2 and a local premium 'Oloyin'. The 4x3 field trials were laid out in a randomized complete block design replicated three times at the Institute of Agricultural Research and Training sub-station, Ikenne and University of Agriculture (UNAAB) Teaching and Research Farm Abeokuta. Soil nematode population densities were assayed using the Whitehead and Hemming tray method prior to planting and at the end of each experiment. Data collected on number of days to 50% flowering, number of seeds/pods, 100- seed weight, nematode populations and grain yield were subjected to analysis of variance, correlation, and cost-benefit analysis with means separated using Duncan Multiple Range Test. Results obtained revealed the presence of economically important plant parasitic tematodes in the two locations, Meloidogyne juveniles, Pratylenchus, Rotylenchulus reniformis and Helicotylenchus species being the host common. Application of carbofuran significantly reduced number of days to 50% flowering by 2-5 days. The relationship between treatment and nematode population was inversely proportional such that the lower the nematode population density the higher the grain yield and vice versa. Nematode population densities were significantly reduced at the lowest 2.4 kg a.i/ha rate of arbofuran with further significant reduction at 3.0kg a.i/ha. The least nematode infested variety was the IT90K-277-2 which recorded te lowest number of days to 50% flowering, highest number of seeds/pods and consequently yielded more grains than Ife-Brown and Oloyin varieties. Cost- benefit analysis indicated higher monetary returns of N 3.851.00kN 21,512.50k difference in profit tributable to carbofuran treatments compared to the control at all levels of application.

Sub-chronic toxicity study of synthetic Pyrethroids (Lambda-cyhalothrin) on reproductive organs of male Wistar rats
(2016) Oshoke, F. I; Fadina, O.O; Fayinminnu, O. O.
Pesticides constitute the most widespread environmental contaminants due to their ubiquitous use in all aspect of human endeavors. Lambda-cyhalothrin (LTC), a synthetic pyrethroid has widely been used for pest control. Human and animals are occasionally and unintentionally exposed to lethal and sub-lethal doses of pesticides stemming from its various uses to control pests both in agriculture and public health. The objective of the study was to evaluate the toxicity of LTC in male reproductivity through testicular tests. The study also investigated the haematological, serum biochemistry and histological effects of sub-chronic concentrations of LTC on male rats. Twenty-five 7-weeks-old male Wistar rats (Rattus norvegicus) were randomly assigned to five groups. Group 1 was the control group, which received distilled water. Experimental groups 2, 3, 4 and 5 received by gavage 25, 50, 75 and 100 mg/kg LTC body weight, respectively, of LTC over a period of five weeks. Histopathological studies were carried out on the testes and seminal vesicles at the end of the experiment. A significant decrease in the absolute weight of testes and seminal vesicles, sperm count, sperm motility and L-D ratio was observed. The results obtained also show marked degeneration of spermatogenic cells associated with interstitial necrosis and congestion with interstitial diffuse edema in the testis of the rat treated with LTC. A typical dose-dependent hyperplasia and degeneration of the seminal vesicles was found in all LTC treated rats with 100 mg/kg body weight and 25 mg/kg body weight having the highest and lowest toxicity level respectively, when compared with that of Group 1. It can be concluded that LTC is highly toxic and may induce poor fertility, cell damage and anaemic conditions in exposed rats.
Utilization of whole cassava plant (TMS 0581) by West African Dwarf Goats.
(College of Agricultural sciences: Olabisi Onabanjo University, 2008) Fasina, O. E.; Ijaduola, O. O.; Bello, A. I.; Fayinminnu, O. O.
Growth and metabolic studies were conducted with twenty four goats (12 males and 12 females). They were fed on ration consisting of basal fresh P. maximum and cassava chips alone or in combination with cassava hay (T1, T2, T3 and T4). Cassava supplements were offered at 1% liveweight (DM). Supplementation with cassava chips, with or without cassava hay decreased (P<0.0001) P. maximum DM intake. However, total DMI of the animals fed cassava- based diets was significantly (P<0.0001) higher than DMI of animals fed T1. Digestibilities of DM, CP and CF were also significant (P<0.0001). Although N intake values were not significant (P>0.0001), animals fed T1 recorded the least N retention value (0.03g/day/W).
