<h1 class="center">Activity: Tomatoes for the Garden</h1>
|
|
<p><span class="larger">How many tomato plants can fit into your garden?</span><br></p>
|
|
<p>And, if all the conditions for growth are right, what is your expected yield?</p>
|
|
|
|
<div class="center80">
|
|
<p><strong>This depends on:</strong></p>
|
|
<ul>
|
|
<li>The size of your garden</li>
|
|
<li>How close together you plant the tomato plants</li>
|
|
</ul>
|
|
</div>
|
|
|
|
<p>Plant them too close and they won't grow well, so you will need to spread them out.</p>
|
|
<p>You could find
|
|
out the best distance between plants from a gardening book, or the internet.</p>
|
|
<p><i>And it may depend on the variety of tomato, so make sure you do your research first.</i></p>
|
|
|
|
<h2>Your first step is to find the shape of your garden and plot it on a sheet of paper.</h2>
|
|
<p>You can do the <a href="garden-area.html">Garden Area</a> activity first if you want</p>
|
|
|
|
|
|
<div class="example">
|
|
<p>As an example, suppose they must be planted 50cm apart,</p>
|
|
<p>How could they best
|
|
fit into the example garden below?</p>
|
|
</div>
|
|
<p class="center"><img src="images/garden-tomato-1.gif" width="223" height="190" alt="garden tomato 1" /></p>
|
|
|
|
<h3>If you plant one tomato plant at random in the garden, say at point X, then where do you plant the next one?</h3>
|
|
<p>It has to be at least 50cm away, so it could be anywhere on the <b>circumference
|
|
of the circle</b> of radius 5ocm, like this:</p>
|
|
<p class="center"><img src="images/garden-tomato-2.gif" width="266" height="175" alt="garden tomato 50cm" /></p>
|
|
|
|
<h3>Choose any spot on the circle, then draw another circle ... like this:</h3>
|
|
<p class="center"><img src="images/garden-tomato-3.gif" width="224" height="188" alt="garden tomato 2" /></p>
|
|
|
|
<p>Continue on like that ...</p>
|
|
<p class="center"><img src="images/garden-tomato-4.gif" width="222" height="188" alt="garden tomato 2 rows" /></p>
|
|
<p>Just make sure each plant is no closer than 50cm to any other one.</p>
|
|
<p><b>That was just one way</b> ... not even a good one, as there is wasted space along the edge of the garden.</p>
|
|
<p>So hopefully you can do better.<br></p>
|
|
<h2>Here are some ideas:<strong></strong></h2>
|
|
<ul>
|
|
<li>Pick a good starting position (in other words, where do you place point X?)</li>
|
|
<li>Is it better to start measuring from one edge of the garden? But then, not all edges are straight, so which edge should I choose?</li>
|
|
<li>Maybe a grid will help, like this one:</li>
|
|
</ul>
|
|
|
|
<p class="center"><img src="images/garden-tomato-5.gif" width="229" height="185" alt="garden on grid" /></p>
|
|
|
|
<p>Keep each of your attempts, it is interesting to see how you can improve on your plan.</p>
|
|
<p>Good Luck!</p>
|
|
|
|
<h2>What is your expected yield?</h2>
|
|
<p>Once you've decided on how many plants you can fit into your garden,
|
|
then you can work out the expected yield of tomatoes from your garden.
|
|
That's a simple multiplication.</p>
|
|
|
|
<div class="example">
|
|
<p>For example, I estimate that I can plant 200 tomato plants in my garden and the expected yield per plant is 5 kg.</p>
|
|
<p>So I expect the total yield to be about
|
|
<strong>200 × 5kg = 1,000kg</strong> or <strong>1 tonne</strong>!</p>
|
|
</div>
|
|
|
|
<p>And, if I sell my tomatoes for $2 a kilogram, then I'm on to a winner.
|
|
Perhaps this is a better choice than having a lawn in my back garden!</p>
|
|
|
|
<h2>But what about the cost of fertiliser and insecticides and all the time
|
|
it takes to nurture those tomatoes?</h2>
|
|
<p>Well, that's another story ... you can work all that out!</p>
|
|
<p> </p>
|
|
|
|
<h2>Follow Up</h2>
|
|
|
|
<p>Instead of planting tomatoes, what about having a
|
|
barbecue party for your friends?</p>
|
|
<p>But how many friends could you invite
|
|
to your party without the garden being overcrowded?</p>
|
|
<p><b>Just use the same method!</b></p>
|
|
<p>Except the plants are replaced by people, and maybe they should be
|
|
two meters apart instead of 50 centimeters. But the idea is the
|
|
same.</p>
