ber in different varieties

[Cranky]

I had a fairly successful season growing about a dozen varieties. All the plants received the same amount of water throughout the season. There was a minimum amount of ber on most of the non plum/paste varieties. I grew opalka, gilbertie and orange banana plum tomatoes and all three had over half the fruit with ber.

Do different varieties require more or less watering and or calcium?

Any help would be appreciated.
