Characteristics of communal club members who use input packages are studied using a survey of communal clubs serviced by Africa Co‐operative Action Trust (Acat) in KwaZulu during 1989. Discriminant analysis shows that full input package adopters tend to belong to older clubs, have less formal savings and receive more visits each year from KwaZulu Department of Agriculture (KDA) extension officers. They also have a greater proportion of land under sugar‐cane, larger farm sizes and a higher rand monetary value of livestock.

Members of older clubs benefit from greater club experience in ordering inputs and liquidity for securing discounts on bulk orders. Clubs also enable scarce KDA extension manpower resources to be used more effectively by focusing extension efforts on groups rather than individual farmers. Sugar‐cane production probably indicates member willingness to innovate and the availability of funds to buy complete input packages for other crops. Increased access to land promotes input package adoption which can raise agricultural productivity. Development of institutional arrangements for a land rental market in KwaZulu should be considered. Higher monetary values of livestock reflect Increased ability to bear risk associated with technology adoption and that adopters have the means to purchase input packages  相似文献

There is a sizeable group of self-described Christian companies which have declared their belief in the successful merging of biblical principles with business activities. As these companies have become more visible, an increasing number of anecdotal newspaper and magazine articles about these companies have appeared. Surprisingly, no rigorous research has been conducted prior to our recent study. This article provides national estimates of the size and predominant characteristics of self-identified Christian companies. In addition, the study investigated the types of relationships these companies maintained with their employees, customers, communities, and suppliers.Nabil Ibrahim is an Assistant Professor of Business Administration at Augusta College, Augusta, Georgia.

The increasing number of women in the work force has forced some companies to take a critical look at their maternity policies. Direct costs for these policies are hard to measure. But, demographic, social and legislative pressures may force companies that haven't addressed this issue to do so in the '90s.  相似文献

A basic needs survey was conducted among people living on two agricultural smallholder schemes in Venda. The paper describes the research methodology and assesses the availability of education and the nutritional status of respondents on these two schemes.

Neither the availability of formal schooling nor extension work is satisfactory. The situation regarding primary education has improved over the last few years and almost every child in the survey area goes to school. This seems to be an indication of changing attitudes among parents, increased money available for schooling, as well as greater financial commitments from the Government. However, informal training through extension is carried out only on an irregular basis.

An assessment of the frequency of consumption of various foodstuffs suggests an emphasis on carbohydrates at the expense of proteins, minerals and vitamins. Villagers interviewed indicated that food is in short supply and that allocation of additional land could assist in overcoming these shortages.  相似文献

The aim of the paper is to investigate certain aspects of the post‐adoption behaviour of dryland cotton farmers in the Ubombo and Hlabisa magisterial districts of KwaZulu. Particular attention is paid to the socio‐economic determinants of the success (returns per hectare) of the household cotton enterprise.

Multi‐stage sampling methods were used to draw a random sample of fifty cotton‐farming households from each of the two study districts. The data were collected by interview survey and analysed using principal components and regression techniques.

Results suggest that the success of the household enterprise in both areas is largely determined by the socio‐economic environment under which the producer operates. The most important success‐determining factors are those relating to the human capital endowments and economic status of the household.  相似文献
