Honey harvest is mainly dependant of 4 things:
1. Strength of colony, the more bees the more honey.
2. Pastures, the more flowering plants in a given area the more the bees can harvest.
3. Duration and timing of honey flow(s). Some areas, like mine, have more than 1 honey flow per season.
4. Weather. Inclimate weather can decrease the amount of time bees have to collect nector, too dry can effect the amount of nector available. Your best harvest will come from years of "normal" weather.
With proper management of bee hives, strong hives, good pastures, long length and/or duration of honey flow, and fair weather a person can get more than 300 lbs per hive.
If starting from a package in the April, I caution not to expect a harvest the first year. The 1st year is the development year, just getting it strong enough to collect enough stores for the winter is a major achievement. A harvest the 1st year is serendipity.
