The paper examines effects of agricultural extension on crop yields in Kenya controlling for other determinants of yields, notably the schooling of farmers and agro-ecological characteristics of arable land. The data we use were collected by the Government of Kenya in 1982 and 1990, but the estimation results reported in the paper are based primarily on the 1982 data set. The sample used for es...

An attempt was made to determine the overall farm-specific technical efficiency or inefficiency of onion farms of Bangladesh. Farm-level data were used for the estimation of the parameters of Cobb-Douglas stochastic frontier production function. The model for technical inefficiency effects in the stochastic frontier included age, experience, education, and farm size. The elasticity of output wi...

More recently, areas have emerged where swine production is concentrated and where it is no longer possible to simply handle manure as a raw crop fertiliser. Some of the factors responsible for that concentration include a decrease in the number of farms, increasing average farm size, access to feed, labour, packing plants, etc. Consequently, it is crucial to develop new production practices or...

In this paper some concept of fuzzy set have discussed and one fuzzy model have applied on agricultural farm for optimal allocation of different crops by considering maximization of net benefit, production and utilization of labour . Crisp values of the objective functions obtained from selected nondominated solutions are converted into triangular fuzzy numbers and ranking of those fuzzy number...

The socio-economic development of largely subsistence-oriented rural areas is a prominent policy objective in Laos. Whereas in the surrounds of major urban centres and regions with favourable infrastructure and market access a dynamic industrial and service sector have emerged, most of the countryside remains economically undeveloped. Cultivation of commercial tree species is acknowledged as a ...

Abstract We examine the informal exchange of labour in farming villages with successful adoption labour-intensive practices. Previous studies have characterised network pattern to relate such cooperative behaviour community’s social structure. use patterns from literature and recreate internal structure selected Bhutanese determine type enforcement mechanisms used. Results show that networks th...

  T he purpose of this study was to examine farm operations cooperation groups in Central Agricultural Zone of Delta State, Nigeria. All the members of the six  selected groups were used for the study. The data which were collected with the use of questionnaire and interview schedule were analyzed with the use of frequency counts, percentages and Tobit regression model. Most of the members we...

Between 1700 and 1850, English grain yields were substantially higher than those attained in other countries. It is widely believed that yields were constrained by the availability of nitrogen, and that supplies of nitrogen were effectively limited to animal dung produced on the farm. This paper presents the first systematic analysis of off-farm sources of nitrogen, such as urban and industrial...

Land use and management change is a feature of New Zealand farm systems, driven by a range of factors including volatile markets and exchange rates, variable weather and climate patterns, continuous policy evolution and the inherent innovation of New Zealand farmers. Yet the common indicators used to evaluate the impact of change appear to be limited to the link between productivity (of land/la...
