Welcome to the forum! I’m going to give you some numbers for Kansas which is a challenging environment to grow fruit. Yield is more complicated than you would think. If i use manure and woodchips on my pears my average yield is a bushel per tree depending on variety and quality of fruit i wish to obtain. Some types like kieffer, duchess d’ angoulme, douglas etc. will easily yield as much as apples. Sunshine and water matter. Some pears like seckel might yield 2 or more 5 gallon buckets. I have pears that you will get only 1 gallon from the entire tree. A full grown apple about 7 -10 years old will yield 4 -8 bushels in my area. Peaches are very heavy producers. My reliance yield about 1 bushel per tree.
This is how i have grown things historically
This is normal reliance peach yield from 1 tree which is 1-2 bushels every other year for me.
