Efficiency of organic rice farming inputs in the dry season at Purworejo Regency, Central Java, Indonesia

Abstract

Climate change will cause changes to the organic rice production inputs. This research aims to know the factors and season determining the production of organic rice, as well as to know the efficiency level of organic rice farmin, toog. The research was carried out in three villages, namely Bleber, Legetan, and the Ngainan villages in Bener District, Purworejo Regency, Central Java, Indonesia. The samples were taken by a census technique, all were organic farmers which were member of the farmer group. There were total of 92 farmers respondents. The primary data were obtained by interviewing with the questionnaire. Then, the data were analyzed using the production model of Cobb-Douglas. The results showed in general, the land, seed, manure, petroganic fertilizer, labor and season significantly influenced the organic rice production. While in the partial areas, it was only manure, labour and season. The use of the land and labors on the organic rice farm has been efficient, but not with the use of manure, yet. The risk of organic rice in the dry season is higher than the rainy season.
