The main objective of this research was to study the educational impacts of the project of integrating population and environment education in agricultural extension in the field of sustainable agriculture in Ariamon village, Kafr El-Sheikh Governorate, through achievement the following specific objectives: (1) Determining knowledge levels of respondents related to sustainable agriculture practices, (2) Determining the respondents implementation level of sustainable agriculture practices, (3) identifying the obstacles facing respondents regarding implementation sustainable agriculture practices, (4) Studying the correlation and regression relationships between knowledge degree of the respondents and the studied independent variables, (5) Studying the correlation and regression relationships between the respondents implementation degree and the studied independent variables.           A well prepared and pretested questionnaire was used to collect data of this research through personal interviews from two systematic random samples, one of them amounted to 120 respondents from Ariamon village (the project was implemented in) and the other amounted to 96 respondents from Taifa village (outside the project). Percentages, frequencies, arithmetic mean, standard deviation, simple correlation coefficient, multiple correlation and regression analysis (step-wise) were used to analyze data statistically. The most important findings of this research were as follows:           The knowledge level of respondents in the project was higher than the knowledge level of respondents outside the project. There were significant differences between the two samples under study (in the project & outside the project) at 0.01 level of significance which reflect the knowledge effect of the project.           The implementation level of respondents in the project was higher than the implementation level of respondent outside the project.           There were significant differences between the two samples under study (in the project & outside the project) at 0.01 level of significance. Which reflect the implementation effect of the project.           The main obstacles facing the respondents regarding implementation of sustainable agricultural practices were: lack of knowledge about the practice, lack of requirement, and lack of extension information about practices.                     All the independent variables of this research explained about 23.2% of the variation in the knowledge degree about sustainable agriculture.           The results indicated the importance of sources of information, and attitude towards barriers of using pesticides as the more effective variables in the knowledge degree about sustainable agriculture       The main objective of this research was to study the educational impacts of the project of integrating population and environment education in agricultural extension in the field of sustainable agriculture in Ariamon village, Kafr El-Sheikh Governorate, through achievement the following specific objectives: (1) Determining knowledge levels of respondents related to sustainable agriculture practices, (2) Determining the respondents implementation level of sustainable agriculture practices, (3) identifying the obstacles facing respondents regarding implementation sustainable agriculture practices, (4) Studying the correlation and regression relationships between knowledge degree of the respondents and the studied independent variables, (5) Studying the correlation and regression relationships between the respondents implementation degree and the studied independent variables.           A well prepared and pretested questionnaire was used to collect data of this research through personal interviews from two systematic random samples, one of them amounted to 120 respondents from Ariamon village (the project was implemented in) and the other amounted to 96 respondents from Taifa village (outside the project).
