  There are many aspects regarding the success of dairy cattle management and productivity. In this study, amount and kinds of feed, costs of veterinary consultancy, herd size, labor and capital were utilized to estimate technical efficiency of dairy cattle management in small scale farms in the east Mediterranean region of Turkey. A non-parametric efficiency analysis was used for the data obtained through face-to-face interviews in 100 small scale farms. We used tobit regression analysis to determine the effectiveness of possible factors affecting production performances of the farms. The results suggested that the average technical efficiency is unsatisfactory since Constant Returns to Scale (CRS) and Variable Returns to Scale (VRS) values are relatively <1 (0.59 and 0.83, respectively). Only 13 and 46% of the farms were found to be efficient in terms of CRS and VRS, respectively. Data Envelopment Analysis (DEA) showed that the farms had excess input usage ranging from 10-22%. To increase efficiency scores in subsidiary profit farms in semi-arid east Mediterranean conditions, farmers should adopt new methodologies, which decrease the costs and excess input usage in such semi-pasture management systems.

  This study analyzes social-economic characteristics of apple farms in Antalya province and reveals economic structure of apple farming. Technical efficiency of apple farming was also analyzed. Data were collected through personal interview from 60 agricultural enterprises during 2001 production year. Average size of the apple orchards in the study area is 12.46 da. Share of the total apple land in total farm land is 28.47%. Annual average gross margin of apple production consists of 67.91% of total gross margin of the farms surveyed. Traditional farming technique is prevailing in the region and farmers interviewed are growing traditional apple varieties. Unit cost of apple produced on the farms surveyed was calculated to be 161.269 TL kg-1. On the other hand, apple is sold at a price of 280.581 TL kg-1. Accordingly, profit margin was calculated to be 119.312 TL kg-1. Technical efficiencies of apple production were estimated with Data Envelopment Analysis (DEA) and found to be 0.69 and 0.92 for constant and variable returns to scale assumptions, respectively. The greatest input slacks were in fertilizer use (K, N and P respectively). Therefore, to achieve a technically efficient apple production, appropriate soil tests should be conducted to determine fertilizer requirements of the soils.
