Avoiding delay after falling:
To avoid crumpling after hitting the ground after falling, perform a double jump immediately before landing.
First you will need to have your harvest area in front of Yonah's house available. To do that you will have to complete a quest from the first shop area, it's the woman in the blue dress sitting on a bench under a tree on the right hand side. You won't be able to do do the quest right away, I think its a couple hours into the game. After you complete the first quest from her, you should immediately do the second one to unlock the rest of your harvest area.
Once you have your harvest area available, go to the second village (south of the beginning shop and along the path, you should know where it is by now) to buy 15x rice plant seedlings, then buy 15x bounty fertilizer from the item shopkeeper.
Go back to Yonah's house and use the bounty fertilizer on all 15 harvest spots, then plant a rice seedling on every spot, then water every spot. After you've done that, save the game. Quit the game and go back to PS3 main menu, go into your clock and time settings, change your (ps3) date by 1 day, then load the game. All your stuff should be grown, you usually make around 90,000 100,000 every time you do this.
