More than 400, 000 smallholders.=>Sample=123 each=>Key informants=>Finding the farmer for more than five years=>Personal interview
Constructs are operationalized as latent variables and all variables are measured as reflective scales> Variables were operationalized by question items with 7 points likert scale.
Regression Model (Research Model)
OPPOR = bo +b1REDURA +b2SALESVOL +b3SUDEV+ ԑ
R2adj=.26 F (7, 65) = 4.54 p<.001 Values for REDURA and SATIS are mean centered scores
**p<.05 t- values greater than 1.64 are significant at 0.05 one tail
***p<.01 t-values greater than 2.33 are significant at 0.01 one tail
