Then the results of the study on the second objective showed that the factors significantly influenced the environmental friendly behavior of the women farmer group of the Sustainable Food Yard (P2L) program in Pariaman City with df = 4, X table = 9.49 with the Chi-Square Test, namely age with X2 = 10,09, education with a value of X2 = 12,76, farming experience with a value of X2 = 10,58, land area with a value of X2 = 9,76, availability of facilities and infrastructure with a value of X2 = 10.85, extension materials with a value of X2 = 10,55, extension methods with a value of X2 = 11,77, extension media with a value of X2 = 9,91, field practice with a value of X2 = 13,03, These results provide strong statistical evidence to reject H0 and accept H1. The results of the third objective of the study indicate that the environmental behavior of women's farmer group members demonstrates that the implementation of the Sustainable Food Yard (P2L) program in Pariaman City significantly benefits women's farmer groups (KWT) economically by ensuring family food security, enhancing social relationships among group members, and improving environmental quality.
