Yep. If you lay down newspapers or other mulch it really cuts down on weeding. Lay the mulch down early before the weeds get ahead of you. And taller or bushier crops naturally choke out weeds.If you can devote yourself to it, 2-3 hours most days, an acre is no problem.
I should have clarified. I don't do row planting because of the weed issues. I lay out 4 foot wide beds, long as the short section of the garden. Cardboard on the paths between the beds. When grown in beds, taller and bushier crops do a very good job of choking out the weeds, once they get established. For me, I have found that planting in beds instead of rows makes the garden easier to maintain. Your mileage may vary.bushier crops choke out the weeds IF the weeds been kept down till the crops GOT bushy. AND even then, they didnt do a thing for what was between the rows.
