I want to fertilize enough for the most production.

Did you have a good reliable soil test done?
Rabbit manure has a fair amount of Nitrogen, 2.4 percent, which may promote lush green growth at the expense of fruits.
Epsom Salts do little for your tomatoes even if your Calcium/Magnesium ratios are out of whack.
If the soil these tomatoes are growing in is a good healthy soil well endowed with organic matter and it drains well but retains moisture well the tomatoes will grow and produce good fruits.

Couldn't agree more..

Me too! Agree with other two posters. Rabbit manure is great if you need nitrogen. If you already have enough though, it could definitely result in bushier rather than fruitier plants.

I always add a bit of nitrogen like that mid-season after the first set of tomatoes comes. I know how I compost during the winter though, so I have a good idea of my carbon vs. nitrogen levels.

Hope this helps.

You can easily add too much Nitrogen which will cause those plants to grow nice and lush and green and be more atractive to insect pests and not produce more fruits. Too much Nitrogen can also inhibit a plants ability to utilize other nutrients.

I grow my tomatoes with several cups of rabbit poo each and I have small plants with TONS of fruit. I thought that the high nitrogen would make big plants and few fruit. Boy, was I wrong. It's the " magic bean" of the gardening world. I can't say enough good things about it.
