Who planted the Oats?

The thing Adler was showing her was a long big grain, the color of gold. She sent a picture to the underworld forum and it was identified as oats. 

"Oats!!" she gasped and took the grain from his hand. This was food, and it was mature for harvesting. This would relieve the worry she was carrying around about running out of corn and wheat porridge before the newly planted crops could mature for harvesting. 

Even though she was excited, reality quickly put a damper on that excitement because one, she did not know what quantity was available and two, even if she did she had never harvested or processed oats before. 

She put the buddha statue down on the table gently and laid down some incense sticks which were not lit next to it.
