So one cup of tomatoes has about 30 calories in it.

The good: This food is low in Sodium, and very low in Saturated Fat and Cholesterol. It is also a good source of Vitamin E (Alpha Tocopherol), Thiamin, Niacin, Vitamin B6, Folate, Magnesium, Phosphorus and Copper, and a very good source of Dietary Fiber, Vitamin A, Vitamin C, Vitamin K, Potassium and Manganese.

The bad: A large portion of the calories in this food come from sugars.

Because the seeds are grown on the inside, the tomato is actually a fruit, but most people call it a vegetable.

Eating tomatoes is good for heart health. Fresh tomatoes and tomato extracts help lower total cholesterol, LDL cholesterol, and triglycerides.

In addition, tomato extracts have helped prevent unwanted clumping together (aggregation) of platelet cells in the blood - a factor that is especially important in lowering risk of heart problems like atherosclerosis.

Tomatoes can be eaten fresh or as part of a recipe.  A favorite is ketchup.

There are tons of recipes for tomatoes but they are especially great in salads.  A salad with fresh cucumbers, tomatoes and lettuce is a nice refresher on a hot afternoon.

Tomatoes cannot be frozen like some fruits and vegetables can be.  They have to be process first before they can be frozen, usually as an ingredient in a recipe.

Red tomatoes will continue to turn red after they are picked.  What you are eating on your hamburger and buying at the store have been picked about three weeks before they are really ready for harvesting so they get to us without being spoiled. 

But a tomato that has been left to ripen on the vine, has much more taste in it.  Don't be fooled by the "vine left on" gimmick the stores like to use.  These are still harvested about 3 weeks early and leaving them attached to the vine does not make them any taste any better. 

When talking about what kind of tomato to grow, one has many choices to make.

Do I grow indeterminate or determinate?

Indeterminate is a vine type plant.  It will keep growing and producing right up until the first frost.  And if it never froze, it would keep producing.

Determinate tomato plants are a bush type plant.  They will grow to about 4 feet tall, put out all their tomatoes and then they are done for the season.

With the indeterminate type tomato, over a long season, one would expect to get more tomatoes.

If I had the space, I would plant both.

More on Doomsday Tomato

The next decision one has to make is what size of tomato to grow.

There are seven types of tomatoes to grow.  They are:

Beefsteak Tomato

Cherry Tomato

Paste Tomato

Plum Tomato

Slicing Tomato

While beefsteak and slicing will probably give you a cup's worth of tomatoes, it will also take them longer to grow. 

Another advantage to growing beefsteak is you will also get more seeds from one tomato than about 50 cherry tomatoes.

How Many Seeds Does it Produce

I am going to list each type of tomato and give "about" how many seeds one can expect to get from that particular type of tomato:

Beefsteak:  75-100

Cherry: 10-20

Currant: 5-10

Grape: 10-15

Paste: 10-15

Plum: 10-15

Slicing: 50-75

These are by no means 100% accurate but they give us something to work with.

How Many Tomatoes

The next thing we needed to know is, "How many tomatoes" will each type of plant produce?

This will be dependent on the type of plant, the growing conditions, insects, animals, rain and so forth.

But lets start with an average of what we can expect from a determinate plant (indeterminate plants can produce more):

Beefsteak:  25-50

Cherry: 500 to 1000

Currant: 200 to 500

Grape: 250 to 500

Paste: 250 to 500

Plum: 250 to 500

Slicing: 50-75

Once again this is by no means 100% accurate, but gives us someplace to start.

How Many Plants

I am just going to give the figures for the slicing tomato only.  I have chosen the slicing tomato, determinate, as our example.

We can get about 50 tomatoes (we will stick with the low side) from one plant.

One cup is about 30 calories. 

One slicing tomato is about one cup's worth.

One person for one day would need, on a 2000 calorie diet, would need about 70 tomatoes a day.

In 365 days that would be 25,500 tomatoes.

This would mean they would need about 60 tomato plants a year if all one had to eat were tomatoes.  Of course, we are hoping they have other things to eat as well.

So I would keep 300 tomato seeds on hand, hidden in 3 different caches.

Follow the 1/3 rule: 1/3 for growing this year, 1/3 for next year and 1/3 for emergencies.

Color of Tomato

Tomatoes come in a variety of colors.

They can mature green, purple, black, orange, yellow and the favorite red. 

The disadvantage to red tomatoes is birds and other animals are always looking for them.  Scavengers also may be looking for a red tomato.

These are grown above ground so they are susceptible to a number of dangers.

I may want to grow a purple or black tomato in hopes of protecting my crop from some of the above ground dangers.  A person who does not know that tomatoes can come in a number of colors, may pass on a black or purple tomato, thinking that there is something wrong with it.

There is a lot to think about when considering tomatoes.

They do not keep for very long so they would need to be turned into some sort of sauce.

There are several videos on youtube that explain how to save the seeds.

Families of Tomatoes

Tomatoes come as:

Open Pollinated



You want to make sure you use open pollinated or heirloom seeds.  These produce seeds that can be used for propagating.

You do not want to plant hybrids for seed production.  Hybrids do not do well for seed production.  You never know what you are going to get.

But for the first couple of years, you may want to grow some hybrids since that are more disease resistant.  If you do, make sure you separate them from your open pollinates by at least 100 feet to prevent cross pollination.
