Task:
Growing a home vegetable garden is your New Year Resolution. In order to have that super fresh crunchy salad, tomatoes are on the list to be planted. All is going well when it is noticed that some of the tomato plant leaves are yellowing. Some leaves are even turning brown as they die and fall off the plant.
What's could be the cause? An investigation is needed. Look up the causes of yellowing leaves. Here is some handy information for the home gardener on tomato plants.Why Do My Young Tomato Plants Have Light Green Leaves Instead of https://homeguides.sfgate.com › Garden › GardeningThe most cost-effective way to grow your annual crop of tomatoes (Solanum lycopersicum) is to start them from seed. While the little seedlings can start out well, they are heavy feeders and need an ample supply of nutrients. The leaves on the plants may turn pale green if the soil is lacking in vital nutrients.
Tomato Soil Requirements
Tomatoes do best when they are grown in a good garden soil that is rich in organic matter because this helps meet the nutritional needs of the young plants. You'll need to plan ahead for the best results. Two or more weeks before planting, spread 1 to 2 inches of compost or well-rotted manure onto the plantingarea, and dig it into the soil. In addition, spread a slow-release fertilizer, with a 8-32-16 or 6-24-24 formula, at a rate of 1 pound per 100 square feet over the future planting area.
 Draw a graph of time in days on the X axis and
stem height on the Y axis on graph paper.
How to do the graph: Take the average* of control measurements in centimeters for each week and plot that point each week 0, 1, 2 & 3 (7 days apart). Take the average for the experimental measurements for each week and plot that point for each week 0, 1, 2 & 3. Compare the control line with the experimental line. Is there a pattern or difference between the control and the experimental data on stem height?
To calculate the average stem height in centimeters (cm) for each week of the control set and the experimental set, add up the height numbers and divide by the number of height numbers for each column.
What about the blanks in the data? Is there anything to be done about them?What do the results mean for the tomato plants? Does the data support the hypothesis? If not, then suggest another hypothesis to test.What can be done for the tomato plants in the garden?Note: We will not be publishing our work even though sharing is part of step 7.
