This research aimed to identify some of the personal and social characteristics of the respondents, and to determine the relationship between the degree of knowledge and implementation of the respondents' technical recommendations for cultivation of the studied crop (cucumber) under tunnels, the studied independent variables, and the degree of the contribution of the independent variables to the knowledge and implementation of the respondents' technical recommendations for agriculture under tunnels for the studied cucumber crop, identifying the services provided by agricultural extension to the surveyed farmers and identifying the relative importance of the problems facing the surveyed farmers. The total number of cucumber growers, which numbered 100, during February and September. The data was analyzed using the tabular display with frequencies, percentages, weighted arithmetic mean, standard deviation and simple correlation coefficient (Pearson), in addition to using multiple stepwise regression analysis. The most important results were that, A there are three independent variables that have a significant contribution of 37.8% in explanation of the total variance in the degree of respondents' knowledge related to the technical recommendations for the cultivation of the cucumber crop, results also showed that there are three independent variables that collectively contributed a significant amount of 25.3% in the interpretation of the total variance in the degree of respondents' implementation of technical recommendations for the cultivation of the cucumber crop.
