Opis:
This study estimated the profitability and the level of technical efficiency of the onion farms. It also identified factors that contribute to technical efficiency in onion production. Data were collected from 180 randomly selected onion farms using a pretested interview schedule. Partial budgeting techniques and the stochastic production frontier were modeled for data analysis. Profitability indices revealed a value of 0.771 and 0.280 for operating ratio and return to capital invested respectively. The mean technical efficiency score for the farms was 88.35%. Quantities of water and onion seedlings, farm size, household size, and farming experience significantly affected the technical efficiency of the farms. The study concluded that onion production was profitable in the study area.  The government should look into the possibility of providing an alternative source of irrigation for the farmers to conserve water and lower the cost of irrigation.

Opis:
The paper undertakes an assessment of the economics of environmental pollution on cassava-based farmers’ health and production efficiency within the Lafarge cement concession area in Mfamosing, Akamkpa Local Government Area, Cross River State. Data for the study were sourced from 60 cassava-based farmers drawn from neighbourhood and non-neighbourhood locations and analyzed using descriptive statistics and stochastic production frontier techniques. The result showed that farming activities in the area have been dominated by females with an average age of 43 and 35 years of age and household size between 4 and 6 persons. Clearly, the results indicate that cement plant activities have reduced farm productivity over the last 5 years, and has affected the livelihood of the farmers. The study also averred that respiratory diseases, diarrhea, skin rashes, heart disease, asthma, coughs and skin cancer have been the various health challenges suffered by the farmers. According to the study results, farmers lost 44 days due to heart disease, 33 days due to respiratory diseases, and 7 days due to diarrhea. The result of the maximum likelihood estimates (MLEs) of the stochastic frontier production function indicate that hired labour, quantity of fertilizer used and quantity of cassava stem cuttings were the significant variables that influenced cassava yield. The estimated technical efficiency (TE) ranged from 0.45 - 0.99, with a mean index of 0.67 (target group) and 0.57 – 0.99, with a mean of 0.82 (control group). The number of days lost due to illness was the most significant variable influencing inefficiency levels in the study area. It was, therefore, recommended that policies aimed at increasing efficiency should focus on improving health care services in the farming communities, while encouraging efficient level of pollution control by the prescribed cement factory, ab initio.

Opis:
Estimation of the technical efficiency which measures the ability of a company to obtain the maximum output from given inputs or to use the minimum input to achieve given outputs has been considered. Stochastic methods were chosen because of their wide application in research in the whole world. The Translog and Cobb-Douglas stochastic frontiers were fitted in order to estimate the efficiency of milling companies in Poland.
