Análise do potencial produtivo da mamona no estado do Ceará

Abstract

The general objective of this work is to analyze the productive potential of the castor oil in the state of Ceará from a technical, social and economic approach. To obtaining the results, the research followed the following steps: initially, a study took place to tabulate and describe primary data collected through the application of 118 questionnaires to the growers and 120 to the not growers of the castor oil plant in the districts of Boa Viagem, Canindé, Itatira, Pedra Branca, Quixadá, Quixeramobim, Quiterianópolis and Tauá. Secondly, a binary probit regression was made to verify wheter the farmer is a castor oil plant grower or not. Thirdly, a multiple lineal regression of the equation of castor oil plant offer inthe state of Ceará was made concerning the period from 1980 to 2007 and this was possible due the secondary data collected in IBGE and IPECE. The analysis of the data allowed to identify the profile of the growers of castor oil plant and of the techniques used in the production. Thus, one can conclude that the farmer's propensity to plant castor oil plant is being influenced by the area, agricultural income, family total income, financing, participation in association and in the credibility of the program. Finnaly, it was verified that the castor oil plant offer is strongly related with the planted area and with its own price, being necessary investiments in technologies and fairer prices.
