We
remained water the plants 500ml twice a day in the morning and in the evening.
We played music each day after water the plants twice a day for 20 minutes. We started to cover the pot with a box and bring the plant to a non windy place whenever
played the music to avoid confuse either wind is making it moves or the plant
itself.

(1) Why
was the soil weight reduce after 1 week?
When
the soil was taken from its place of origin, there is a lot of content in the soil
such as water, roots, stones and so on. The content of this soil have been
carried along in the soil. And it also affects the weight of the land. The
content of the soil as the water has made it damp and heavy. The water from
rain and the soil absorb the water. When this soil was weighed for the first
time, the weight of this soil is 500 grams. The soil is not exposed to the rain
and dried outside of the laboratory. After drying for one week, the weight of
the soil has been reduced. This is because the water has been evaporated so
that it lead the moisture content decreases .This is why this soil is reduced
weight.
(2) What
is the optimum soil pH for butterfly pea growth?
Adapted to pH 4.5-8.7 but prefers medium to high pH
(3)What
kind of soil does butterfly pea grows well?
Butterfly
pea is Adapted to a wide range of soil types provided fertility and
water-holding capacity is high. Prefers medium to high pH and is well adapted to alkaline heavy clay soils and it is adapted to shallow, heavy clay and
sodic soils (by a disproportionately high concentration of sodium (Na) in their
cation exchange complex). Peas do not like to plant in wet soil. Butterfly pea
grows well with clay loamy soil. It contains a balance of all three soil
materials that are silt, sand and clay includes humus. Adapted to a wide range
of soil types provided fertility and water-holding capacity is high.
Prefers medium to high pH and is well adapted to alkaline heavy clay soils.
(4) How
does the amount of macro nutrients in the current soil use for growing butterfly
affect their growth?
The three major plant macronutrient are Nitrogen (N), phosphorus (P) and Potassium (K). The nitrogen available to plants as a nitrate nitrogen is biologically combined with C, H, O and S to create amino acids, which help in building block of proteins. amino acids are used in forming protoplasm, the site for cell division and thus help in plant growth and development of butterfly pea. phosphorus available to plants as orthophosphate ions or phosphate in phothosynthesis and respiration of butterfly pea, P plays a role in energy storage and trasfer as ADP or ATP. P are aids in the root development, flower initiation and seed development. Pottasium available to plants as K ion. Presence of K is vital for butterfly pea growth because K is an enzyme activator that promotes metabolism. in Phothosynthesis, K will maintain the balance of electrical charges at site of metabolism. In phothosynthesis, K will maintain the balance of electrical charges at site of ATP production. K also will promote the translocation of phothosysnthesis for butterfly pea growth or storage in roots. Another macronutrient which is sulfur available in plants as sulfate ion which is essential in forming protein of buttefly pea because it is constituent of certain amino acids. S aids in seed production, chorophyll formation and stabilizing protein structure in development of growth in butterfly pea.
The group has ascertained that the soil pH property is suitable for the growth of the plant.
ReplyDeleteLater in the overall summary report how will the group conclude the soil use to grow butterfly pea for this mini project by analysing results related to soil pH,soil texture, soil moisture, soil aeration, particle size and water holding capacity for this experiment can make butterfly pea grow happy or not.
Observation from week 1 to week 4, does this group think that exposure of music is influencing the germination rate of the seeds? and plant/shoot/root growth?
Suggestion: If you make a graph that can show the difference of germination and plant/shoot/root growth according to week and music might make it more clearer to interpret the data.
Next week the group members can dug out 5 seedlings from each pot.
Measure the length of the plant/shoot/root growth.
Count the nodules from each plant.
Compare the average no. of nodules/plant/shoot/root growth length for each music genre and control.
How do you relate the nutrient absorption and the number or nodule for different pot.
Discuss what is nodule, its function and benefit.
Don't forget to address research questions of this mini project.
I see an improvement of how the group analyse their results.
