“…Further, this accords with prior studies that have found a negative relationship between farm size and level of technical efficiency in agricultural production (Bravo-Ureta & Evenson, 1994;Ali et al 1994;Hallam & Machado, 1996;Bozoğlu & Ceyhan, 2007). For Greek olive farms, Tzouvelekas et al (2001) suggested that larger farms tend to have lower efficiency than small farms. These results imply that enlarging the irrigated area does not contribute to efficiency increases in Jenin, whereas more intensive cropping with mature olive trees is a positive factor in improving efficiency.…”

“…In addition, and again for olive farms in Greece, Karagiannis and Tzouvelekas (2001) suggested that scale and allocative efficiency played a significant role in explaining output growth during the period 1987-1993. As for the determinants of efficiency, Tzouvelekas, Pantzios and Fotopoulos (2001) found a higher degree of efficiency in organic farming compared with conventional farming in Greece. For olive farms in Turkey, Cukur, Saner, Cukur, Dayan and Adanacioglu (2013) suggested there are huge differences in technical efficiency among olive farms and most olive farms do not operate in their optimal scale.…”

This study examines the firm-level technical efficiency of olive-growing farms in the West Bank of Palestine. Using a sample of 176 olive farms in the Jenin governorate collected during September 2015, we estimated the Cobb-Douglas stochastic frontier production function. The results suggest that higher levels of education of the head of farm households and farms with a higher density of olive trees are associated with higher technical efficiency. The introduction of irrigation had a marginal effect on upgrading efficiency. Enlarging the irrigated area had a negative effect, but increasing the number of years of irrigation had a positive impact on efficiency. While the impact of access to export markets on technical efficiency was negative and farms oriented towards domestic consumption of olive oil showed lower efficiency, access to markets through olive presses and middlemen contributed to improve efficiency. The results of the chosen half-normal model suggest that olive farms in Jenin have the potential to increase production by 51.4% through more efficient use of technology and production inputs. These results imply promotion of intensive farming with mature olive trees and expansion of market access could contribute to improve technical efficiency of olive farms in the West Bank even under severe geographical and geopolitical conditions.

“…So far, other comparisons have been made between conventional and organic farming and Mediterranean cultures, such as Greek olive-growing (Tzouvelekas et al, 2001a) and cotton farms (Tzouvelekas et al, 2001b). These works, though, do not calculate pollution shadow prices and are restricted to the computation of efficiency indexes with no consideration of environmental impacts, as in the aforementioned works by Oude-Lansink et al (2002) and Sipiläinen and Oude-Lansink (2005).…”

Organic farming integrates environmental concerns and criteria within farm management practices in order to reducethe environmental impact of agricultural production. In this paper, the shadow price of two of the main indicators of pollution arising from agricultural practices, nitrogen surplus and impact of pesticides, are calculated and compared in a context of Mediterranean climate and cultures. Results show that it is more costly for organic farms to reduce their levels of pollution emission than for conventional farms. This may be due to the fact that the specific regulations on organic farming restrict agricultural practices to a larger degree than current restrictions affecting conventional farming. These results suggest that organic farming might be an adequate answer to part of the environmental problems provoked by conventional farming.

“…on the other hand, the input-oriented technical efficiency score is 73.12 for the organic olive farms and 54.30% for the conventional olive farms (Tzouvelekas et al 2001). in Tunisia, the average technical efficiency score is 82% for olive farms (Lachael et al 2005).…”

For this reason, there is a strong demand for such studies which search the technical efficiency comparing the conventional and organic production in different products.…”

This paper investigates technical and economically efficiency of 62 organic and 62 conventional olive producing farms in Turkey. According to the study results; by using the crS model which is input and output-oriented, the average technical efficiency of organic olive farms is 67.68%, the average technical efficiency of conventional olive farms is 47.93%. The technical efficiency of the output-oriented VrS model is 74.78%, and the technical efficiency of the input-oriented VrS model is 93.46%. Also, considering the same model, the average efficiency of the conventional olive farms in the input and output are 59.58% and 94.97%, respectively. Therefore, according to the Data Envelopment Analysis, the technical efficiency in conventional olive farms is less than in the organic ones. When the farms have been evaluated one by one in the light of the total potential improvement values, inputs and outputs, improvement is needed in all values.

Podle výsledků studie na základě využití modelu crS orientovaného na input-output je průměrná technická efektivnost konvenčních farem 6,68 % a průměrná technická efektivnost ekologických farem 47,93 %. output-orientovaný VrS model technické efektivnosti vykazuje hodnotu 74,78 % a input-orientovaný VrS model 93,46 %. Uvažujeme-li tentýž typ modelu, je průměrná technická efektivnost konvenčních farem v input-orientovaném modelu 59,58 % a v output-orientovaném modelu 9,97 %. z analýzy dat pak vyplývá, že technická efektivnost konvenčních farem je nižší, než u farem ekologických. Když pak byly farmy analyzovány jednotlivě z hlediska celkových hodnot potenciálního zlepšení efektivnosti, bylo zjištěno, že zlepšení je žádoucí ve všech zkoumaných hodnotách.
