My father had loquat tree that had variable production, which depended a lot on the weather and irrigation. Make sure the soil is loamy, well drained and irrigate modestly. The number of fruit is determined by the number of flowers. I'd recommend following the instructions in the articles regarding fertilizer, but perhaps use slightly less. As Evo and turbo-1 indicated, one wants to avoid over-production, which can be controlled by removing flowers on the outer ends of the branches.
