Practices of Farmers in Production and Marketing of Tomato in Nsukka Local Government Area of Enugu State, Nigeria

The study described socio-economic characteristics, production, consumption and marketing patterns of tomato farmers as well as constraints they encounter in tomato production in Nsukka Local Government Area of Enugu State, Nigeria. One hundred and twenty tomato farmers randomly selected form twelve villages in the area constituted sample for the study. Data were collected with interview schedule and questionnaire and were presented with frequency, percentage and mean scores. Findings show that the respondents were mainly married (71%) women (72.5%) who were literate with mean age and mean farming experience of 42.22 years and 17.21years respectively. Greater proportion of the respondents grew tomatoes on communal land (31.7%) with personal savings (42.5%) and hired labour (45%). They grew tomatoes during rainy season (54.1%) using personal reserved seeds (53.3%). Lack/poor storage facility (M=2.00) and fluctuation in price of tomato (M = 2.13) were some of the serious constraints to production and marketing of tomatoes respectively in the area. The study recommends that government, non-governmental organisations, self help development organisations/agencies as well as philanthropists should assist in provision of storage facilities for tomatoes so as to reduce losses and ensure preservation and availability of the product all year round at reasonable and stable price

Short-term aerobic exercise does not change kidney function in students of Nnamdi Azikiwe University, Nigeria

Background Exercise has been known to have beneficial effects on human health. The kidneys play an important role in regulating acid-base and water-electrolyte balance disturbances induced by exercise. The objective of this study was to investigate the effect of short term aerobic exercise (volleyball training) on the kidney function of apparently healthy individuals. Methods An experimental study of pre-post test design was conducted involving 41 amateur volleyball players, comprising 22 males and 19 females. They were randomly divided into seven different teams. Each team trained for at least 45 minutes for four consecutive days for two weeks. Both pre-and post-exercise blood pressure (BP) was measured using an automatic blood pressure measuring device OMRON 907 (OMRON, Hoofddorp, Netherlands). Likewise, both pre- and post-exercise blood samples were collected into lithium heparin tubes and centrifuged at 3000 rpm for 10 minutes and the plasma separated into plain tubes. Electrolytes were analysed using ion selective electrode machine (SFRI 4000, Germany), urea using modified Berthelot method, creatinine using Jaffe-Slot method and uric acid using the uricase method and estimated glomerular filtration state (eGFR) was calculated using the Modification of Diet in Renal Disease (MDRD) formula. Results The mean levels of pre- and post-exercise systolic blood pressure, creatinine, urea, sodium, potassium, chloride, bicarbonate and eGFR did not differ significantly (p>0.05). However, serum uric acid was significantly increased (p<0.05), while diastolic BP significantly decreased after exercise (p<0.05). Conclusion The study showed that short-term moderate intensity aerobic exercise does not have any significant effect on the renal functions
