A farmer has noticed that his soybean plants produce more beans in some years than others. He claims to always apply the same amount of
fertilizer to the plants but he suspects the difference in crop yield may have something to do with the amount of water the crops receive. The
farmer has observed that the soybeans on his farm usually receive between 0 to 0.5 inches of water per day, but he is unsure of the optimal
amount of water with which to irrigate.

Use the scientific method to address the farmer's needs:
а
In Data Table 1, state a research question that will directly address the farmer's problem.
b
Conduct online research on "soybean crop irrigation." Record pertinent information and the web sites you used in Data Table 1.
Do not copy text directly from the sources, as this is considered glagiarism.
С
Construct a testable hypothesis. The hypothesis should be phrased as a complete sentence, able to be supported or refuted by an
investigation. Record the hypothesis in Data Table 1.
d
Design an experiment to test the hypothesis. Be as specific as possible in describing what will be observed or measured. Record
your study design in Data Table 1.

Sagot :

A research question is the central focus of your investigation or study. It should be completely straightforward and contains enough details so that the intended audience may comprehend it without further explanation.

2a.

From the given information, the research question is:

  • Is there a connection between the crop output and the quantity of water that crops receive?
  • If so, how much water should you use to get the best soybean yield?

2b.

Both sources of information used here were adapted from Missouri Edu. and Krugerseed.

Source 1:

  • At different phases of growth, soybeans require varying amounts of water. It ranges from 0.05 - 0.1 inches per day during germination and seedling development is up to 0.25 - 0.35 inches per day during pod development.

Source 2:

  • Water at a rate of 0.20 - 0.30 inches per day is sufficient for the bulk of the soybean's growing cycle.  Soybeans have a decreased water demand (i.e. 0.05 inches per day) as they mature.

However, the amount of irrigated water depends on several parameters including:

  • soybean species,
  • farmland location,
  • rain proportion, and:
  • soil type.

It is critical that the soybean plant get the maximum amount of water possible; thus, irrigation should be used to restore the rainwater deficit.

2c:

A testable hypothesis is a hypothesis that can be confirmed or refuted by testing or collecting data.

From the given information:

The hypothesis is:

  • Soybean produce is not influenced by the quantity of irrigation water applied to the crop.

2d:

The Design experiment for the test hypothesis is as follows:

  1. Use the same soybean species that is widely grown in that farmland area or by farmers for agricultural cultivation.
  2. Fill 16 pots with the farmland soil and the seedlings.
  3. Consider germination, vegetative progression, flower blooming and pod filling, and maturity as four phases of growth. Change the water quantity (inches per day) for each stage to 0.05, 0.1, 0.2, and 0.
  4. Keep track of plant growth, leaf size, chlorophyll content, days till flower blooming, pods number, seeds per pod, and 100-grain weight.
  5. Perform statistical analysis to determine which watering conditions produce the greatest yield of soybean production.

Therefore, we can conclude that from the above concept and explanation, we have understood how to carry out a Research Study, testable hypothesis, and designing a perfect experiment to carry out the hypothesis.
