As long as the manure is composted go ahead and use it. I wouldn't want fresh manure anywhere near what I plan on eating. And depending on where you are, the first frost could be coming in just a couple months. So there's not much time left to get a fall garden planted (and it might be too late for broccoli but again it depends on where you are).

Sounds like your tomatoes have blossom end rot (BER). I suggest you do a search about it over on the Tomato Forum.

Agree that we need to know where you live as that tells us what your climate is like. That tells you how far ahead of planting you would add the manure.

Also agree that you should never use fresh manure anywhere in a food garden. Use well-aged, composted manures only. This is especially important when growing low level crops like lettuce and other things where the edible parts will come into direct contact with the soil.

Plus community gardens will usually have guidelines for when you can add/use manures.

So could you provide us with more information please?

Assuming you used composted manure, then yes, it wouldn't hurt to add more for a second crop in the same year - if you still have time. . And yes, you can grow those crops in the same place you grew tomatoes previously.
