Midrasz do Psalmów 111:4

3) "and the earth shall yield its produce": Not as it does now, but as it did in the days of Adam. And whence is it derived that the earth is destined to be sown and to give fruit on the same day? From (Tehillim 111:4) "A portent (in the days of Adam) He made for His (future) wonders," and (Bereshith 1:11) "Let the earth sprout vegetation, grass, etc." — whereby we are taught that on the same day that it was sown, it gave forth fruit.
