The study aimed measuring the efficiency of using the extension methods by researcher, defining the relative importance of well-studied extension methods according to how the researchers use them, explaining the relation between the efficiency of using extension methods and some of variables, defining the rate of changes related to the positive correlation relation in explaining the total difference to the efficiency of researcher use to the studied extension methods and pointing out some troubles that face researchers on using the accurate extension methods and their proposals to some of the problems as they think. These data were collected by a questionnaire through interviewing the researchers. The most important results that could be achieved were: The use of the low or medium extension methods can be arranged according to the public extension methods then to the individual methods and to collective extension methods at last. About the rate of efficiency of using high extensional methods, they were effective as follows the collective then the individual and the public methods at last. The comparative importance of extension methods according to the researchers efficient use. It was clear that field visits came on the first place of importance, while the library visits came the second. That means visit, by all means are the most widely used because it takes place in condition familiar to the farmers. In addition, the extension on meetings and practical explanation meetings were highly used yet, public extension methods came at the end of list of importance. There is a positive and important relation between the use of extension individually methods and degree of training degree of practicing extension activities at the level late of (0.05 %). There is a positive relation at the rate of .01 % between the use of extension methods grouping and job experience and job satisfaction. There is a positive relation between the use of extension massing methods and the degree of job experience and degree of practicing extension activities at percentage of 0.01. |
