Introduction The increasing population growth and the need for more agricultural products on the one hand, and on the other hand, the limitations of agricultural development are problems that human beings have always tried to solve. Due to the limited resources and inputs of production, it seems that further production growth is possible through advanced technologies. In fact, technology is so...

alcohol in iran is produced mainly from molasses of sugar cane and sugar beet. other sources of alcohol production like wheat and barley exist, but because of some cultural and political reasons, they cannot be legally used for producing alcohol in iran. twenty-six manufacturers in 18 provinces are officially active. the actual capacity of ethanol production with medical purity is about 100mill...

The aim of this paper is to use the concept of the metafrontier function to study the determination of efficiency differentials and Technological Gap Ratio (TGR) on wheat production in Khorasan Razavi province. In this study, we used the metafrontier function and group frontier based on the concept of Stochastic Nonparametric Envelopment of Data analysis (StoNED). The data used in this stud...

The paper presents a metafrontier production function model for farm’s different groups having different technologies. The metafrontier model enables the computation of comparable technical efficiencies for farms operating under different technologies. The model also enables the technology gaps to be estimated for wheat farms under different technologies relative to the potential technology ava...

This study is aimed at evaluating and measuring the factors affecting the Dezful wheat farmers` attitude toward the extension of wheat waste reduction. The method of research was correlative- descriptive. The population of this study is all farmers cultivated wheat in Dezful from 2011 to 2012 (n=5291). The Number of samples size was 360 based on Krejcie and Morgan table. Panel of experts and Al...

the technical, allocative and economic efficiency of wheat growers in baft, kerman province were studied to analyze the degree of farmers success in the optimun allocation of their resources and the possibilities of increasing the production based on the available resources and factors of production. sampling was based on random method, so 75 farmers were selected. the stochastic frontier produ...
