(PEANUT)
26 April: After 1 week of seed sowed.
- Each
pot of the plant was put outside the lab every day so that the plants have
enough sunlight uptakes.
- Each
of the pot is watered everyday with water volume: 560 ml at 10:00am.
·
Pot 3 of peanut plants shows the best growth as
can be seen on the picture below where the plant in the pot has the highest
germination rate.
1. Pot A
·
Soil pH value : 5 or 5.71
·
Average plants’ height : 0 cm
2. Pot B
·
Soil pH value : 5 or 5.69
·
Germination rate: 50%
·
Average plants’ height : 6.88cm
3. Pot C
Soil pH value: 7 or 7.79
Germination rate : 80%
Average plants’ height : 7.62cm
4. Pot D
·
Soil pH value : 5 or 5.71
·
Germination rate : 50%
·
Average plants’ height : 6.27cm
5. Pot E

Revise:
ReplyDelete(1) Separate soil pH according to method, which is which.
(a)pH paper
(2)pH meter
(2) Determine the soil texture type.
Show the layer difference from the jar test.
Texture by feel.
Show how the calculation is done to draw the line on the textural triangulation diagram.
Post on the blog.
Assign this task to Ong Li Ching.
(3) On 9th May 2017, carefully dug out 3 plants from each pots with root perfectly attached.
Measure the weight of the plant, without soil attached.
Measure the length of the whole seedlings/plants from the root tips to green shoots.
Measure the length of the root plant only.
Measure the length of the plant green shoot.
Air dry the plant.
Question:
Why after several weeks now, the colour/hue of green leaves on the plants differs between pots or soil texture? try to associate it with soil nutrient, texture and pH.

2nd week report supposedly on 3rd May 2017.
3rd Week report is due on 10th May 2017.
