Time-related changes in magnesium content and magnesium/calcium ratio of Finnish agricultural soil associated inversely with human CHD in 1961-1990

Toysa Timo*, Hanninen Osmo

Because of reported associations of Mg with cardiovascular diseases (CVD), we assessed changes in soil Mg and Mg/Ca ratio with human CHD in order to clarify, whether these soil parameters could be associated with the human CHD epidemic in Finland. Human CHD and soil statistics are based on old data. Soil Mg and Mg/Ca ratio values are assessed by six successive 5 year periods from 1961 to 1990 (1961-1965, 1966-1970, etc). Mg has been included in basic samples (including Ca and K) since 1986, before it the number of Mg samples was lower and its distribution differed from basic samples.

Abundance of Liriomyza trifolii (Diptera: Agromyzidae) and its Parasitoids on Five Vegetable Crops in Southern Florida

S. Devkota, DR. Seal*, OE. Liburd, S. Ferguson, C Waddill, CG. Martin

In southern Florida and elsewhere, the American serpentine leafminer, Liriomyza trifolii (Burgess) (Diptera: Agromyzidae) is one of the most destructive pests of snap beansPhaseolus vulgaris L. (Fabaceae), cucumbers Cucumis sativus L., squash Curcurbita pepo L. (both Cucurbitaceae), and tomatoes Solanum lycopersicum L. (Solanaceae). In tests with these crops and with cabbage, Brassica oleracea L. (Brassicaceae), we determined and compared numbers of individuals in different L. trifolii life stages, proportions of the larvae surviving to adulthood, and numbers of parasitoids.

Compliance of Finnish Male CHD and Total Mortality with Soil Fertilization in 1957-1990

Toysa Timo*, Hanninen Osmo

Magnesium (Mg) tissue content has been associated with vascular pathology and risks of coronary heart disease (CHD). Associations between fertilization, morbidity and mortality have been studied in veterinary, but less in human medicine. In this study we assessed changes in male (M) CHD and total (TOT) (mortality) and their regressions by fertilization parameters: calcium (Ca), Mg, potassium (K), phosphorus (P), nitrogen (N) and carbonate (CO3) (direct or functions of these parameters) in 1957-1990, when medical treatments were less effective than today. Fertilization parameters are given as equivalents/ha.

Socio-Economic Determinants Of Extension Workers’ Job Performance In Abia State, Nigeria

O.O Ekumankama1, U. S Anyanwu2, V.A Chukwu3

This study ascertained the socio-economic determinants of extension workers’ job performance in Abia State, Nigeria. Primary and secondary data were collected with a structured questionnaire; from 86 respondents, which included 56 Extension Agents, 14 Block Extension Agents, 14 Block Extension Supervisors and 2 Zonal Extension Officers; and analyzed using both descriptive and inferential statistics. These include frequency counts, percentages, means, and regression analysis. A null hypothesis was tested at 5% level of significance. The result of the socio-economic characteristics of the respondents shows that majority 50%, 35.7% and 44.6% of BESs, BEAs and EAs fall within active economic and productive age bracket of 35- 44 years; while the ZEOs were between 45-54 years. Most of the ZEOs (100%), BESs (85.7%) and EAs (48.2%) were males; except BEAs who was mainly females (80%).
