Introduction Agricultural insurance is crucial to reducing financial exposures and vulnerabilities, managing the production risks of poultry farmers while also hunger levels. Unfortunately, it has not been effective in developing countries, like Nigeria. Methods This study examined outcome agricultural use on egg output efficiency Oyo State, The multistage sampling technique was adopted select ...

Viable sweet potato production is hard to achieve with indiscriminate use of farm inputs, resulting to wastage and environmental damages, as consequences are common problems of arable crop farming in Abia State. Issues arising from farm input use and their corresponding implications for environment called for a study on suitable farming practices and farm-specific technical efficiency for optim...

This paper estimates a stochastic production frontier using time-series data for the aggregate Korean economy in 1977-2005 to examine whether public infrastructure stock reduces aggregate technical inefficiency in the gross domestic product. A stochastic production frontier is estimated in first-differenced form, and the one-sided residuals are regressed against the stock of public infrastructu...

Three stages sampling technique applied draw 186 sample farmers randomly. The interview schedule pre-tested before conducting actual data collection; gathered from households with help trained enumerators. In addition, secondary were collected thr...

known as the inverse problem of the calculus of variations for the system (2.1). For historical reasons, we also refer to this problem as the Sonin–Douglas problem; Eq. (2.2) are called theSonin–Douglas equations. Having inmind the correspondence with classicalmechanics,we sometimes call the system F = (F1, . . . , Fm) the force. The functions g jk are called variational multipliers. If the fun...

This study analyzes the factors influencing gambier productivity, technical efficiency of farming, and affecting farming's efficiency. research was conducted in Lima Puluh Kota Regency, a production center West Sumatra. Data were analyzed using Cobb Douglas stochastic frontier function. The results showed that significantly influenced gambier's productivity labor, NPK fertilizer, plant age, num...
