First, you will need to have your harvest area in front of Yonah's house available. To do that, you must 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 cannot 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 purchase15x rice plant seedlings, then 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. Afterward, save the game. Quit the game and go back to Xbox 360 main menu, go into your clock and time settings, change your system date by one day, then load the game. All your stuff should be grown, you usually make around 90,000-100,000 every time you do this.
