|Title:||Production relations and technical inefficiency in pistachio farming systems in Kerman Province of Iran||Contributor(s):||Boshrabadi, Hossein Mehrabi (author); Villano, Renato (author) ; Fleming, Euan (author)||Publication Date:||2007||Handle Link:||https://hdl.handle.net/1959.11/4116||Abstract:||This paper reports on an analysis of production and technical inefficiency in pistachio farming systems in Iran. A random sample of 233 farmers was selected from the province of Kerman during 2003 and 2004, which is a larger data set with a wider spatial coverage compared with the previous studies on pistachio production. Technical inefficiency indices are computed using a stochastic frontier production function assuming a translog form. The study also reports on productivity and efficiency differences between varieties of pistachio trees and provides estimates of age-yield and density-yield functions. Estimates of mean technical efficiency in 2003 and 2004 are 65.2 and 63.7%, which are not significantly different. The mean technical efficiency scores across both years for plantations of the Kalleh-Ghuchi, Akbari, Fandoghi varieties and for plantations containing a mixture of all three varieties are 65.8, 59.4, 62.4 and 78.7%, respectively. Farmers cultivating the more traditional mixed-variety plantation are more technically efficient than those specializing in one of the three tree varieties. We found a positive relation between technical efficiency and experience, and suggest that extension programmes should be aimed at the less experienced farmers.||Publication Type:||Journal Article||Source of Publication:||Forests, Trees and Livelihoods, 17(2), p. 141-155||Publisher:||AB Academic Publishers||Place of Publication:||United Kingdom||ISSN:||1472-8028||Field of Research (FOR):||140201 Agricultural Economics||Peer Reviewed:||Yes||HERDC Category Description:||C1 Refereed Article in a Scholarly Journal||Other Links:||http://www.foreststreesandlivelihoods.co.uk/index.htm
