update ; vikki

23rd June update :

Today's work
  • Filled up control set up with 150ml each of potassium, nitrate and phosphate as the water was running out.
  • Measured the length of new section and number of shoots for each plant set up.
  • We need to make more liquid fertiliser as its running out.

    Plant [a] - Control setup with all 3 fertilisers.
    Length of new section -> 3.5cm
    Number of shoots -> 4 *one shoot died.
  • Plant [d] - Nitrate + Potassium
    Length of new section -> 1cm
    Number of shoots -> 6
  • Plant [v] - Nitrate + Phosphate
    Length of new section -> 3.5cm
    Number of shoots -> 8 *one shoot died

  • Plant [f] - Potassium + Phosphate
    Length of new section -> 3.3cm
    Number of shoots -> 6 *one shoot died

  • Plant [s] - Control setup with no fertiliser
    Length of new section -> 3cm
    No of shoots -> 9

Signing off,

NEWS FLASH ; farhana

Hey guys!

I've got bad news!
The lab would only be available for us until 26th !
So we'll have to make our conclusion by then.

The lab's not opened on 24th.
But it'll be open 25th from 9am to 11.30am.
We have to meet ASAP!
But I have training during that time.
So how!?

We are Doomed right?
Well but we've done enough observations already.

WE HAVE TO MEET UP, real soon.

Thanks,
FARHANA

update ; Farhana

Hello!

Lately SmallFries have been really busy.
My phone is spoilt and I can't upload pictures but I'll just update first, pictures later.

15TH JUNE 2009

After much thinking, Smallfries decided we would be efficient by counting the amount of new shoots, taking down the length of one new shoot each week and measure the length of the new section. What is a new section? A new section is like a stem but it would end up growing into a new shoot. That way, it would be easier for us to make our conclusion.


Container D (Nitrate & Potassium Only!)

-Added 150ml of Nitrate & Potassium each for the plant

Height of youngest Shoot : 2.2cm
Length of new section (if any) : 1.7cm.
New Shoot(s) : 3.

Container V (Nitrate & Phosphate Only!)
- Added 150 ml of Nitrate & Phosphate each for the plant

Height Of Youngest Shoot: 2cm
Length of new section (if any) : 7mm
New shoot(s): 4 [ One more coming soon! There is actually another new shoot but it is dead due to damage while plantation]

Container F (Potassium & Phosphate Only!)
-Added 150ml Potassium & Phosphate each for the plant

Height of youngest shoot: 3.3cm
Length of new section (if any) : 5mm
New shoots: 2 [ One more coming soon! There is actually another shoot but it's dead due to damage]

Container S ( Water Only! No Fertilisers!)
-Added 150ml of Water

Height of Youngest Shoot: 1.5cm
Length of new section (if any) : 2.9cm
New Shoots : 5

Container A ( With All 3 Fertilisers! Nitrate, Phosphate & Potassium!)
-Did not top up.

Height of youngest shoot: 1cm
Length of new section (if any) : -
New Shoots: 3


16THJUNE2009

We continued with our project.

Container D (Nitrate & Potassium Only!)

Height of youngest shoot: 2.6cm [ grew 4mm! ]
Presence of a new section(if any) : 3.2cm [ grew 15mm! ]
New shoots: 3

Growth > 19mm

Container V (Nitrate & Phosphate Only!)

Height of youngest shoot: 2.4cm [ grew 4mm! ]
Length of new section(if any) : 1.6cm [ grew 9mm! ]
New Shoots : 5 [ additional one more ! ]

Growth > 13mm + new shoot

Container F (Potassium & Phosphate Only!)

Height of youngest shoot: 4.4cm [ grew 11mm! ]
Length of new section (if any) : 1.6cm [ grew 11mm! ]
New Shoots : 3 [ Additional 1 more! ]

Growth > 22mm + new shoot

Container S ( With All 3 Fertilisers! Nitrate, Phosphate & Potassium!)

Height of youngest shoot: 1.7cm [ grew 2mm! ]
Length of new section (if any) : 3.9cm [ grew 10mm]
New Shoots: 5

Growth > 12mm

Container A ( With All 3 Fertilisers! Nitrate, Phosphate & Potassium!)

Height of youngest shoot: 1.3cm [grew 3mm]
Length of new section (if any) : -
New Shoots: 3

Growth > 3mm

Conclusion of the day : F grew the most while A grew the least.

Arrangement from fastest growing to slowest : A,S,V,D,F! [ A & S not really important ]

THUS , Potassium slows down the rate of growth, Phosphate increases growth of plants like Nitrate but Nitrate increases the growth even more.

17THJUNE2009
LEFT THE PLANTS ALONE, EXTREMELY BUSY DAY

18THJUNE2009
Smallfries resumed project.
Container D (Nitrate & Potassium Only!)

Height of youngest shoot: 3.6cm [ grew 10mm! ]

New shoots: 3 (2 more coming soon!)

Growth > 24mm

Container V (Nitrate & Phosphate Only!)

Height of youngest shoot: 3.4cm [ grew 10mm! ]
Length of new section(if any) : 4.5cm [ grew 29mm! ]
New Shoots : 5 [ 2 more coming ! ]

Growth > 39mm

Container F (Potassium & Phosphate Only!)

Height of youngest shoot: 4.6cm [ grew 2mm! ]
Length of new section (if any) : 4.9cm [ grew 33mm! ]
New Shoots : 4 [ Additional 1 more! ]

Growth > 35mm + new shoot

Container S ( With All 3 Fertilisers! Nitrate, Phosphate & Potassium!)

Height of youngest shoot: 2.5cm [ grew 8mm! ]
Length of new section (if any) : Previous Section has grown into a new shoot & there is a new one that is 2cm long.
New Shoots: 6 [ additional 1 more! ]

Growth > 8mm + new shoot + new section

Container A ( With All 3 Fertilisers! Nitrate, Phosphate & Potassium!)

Height of youngest shoot: 2.6cm [grew 13mm]
Length of new section (if any) : 4cm
New Shoots: 4 [additional 1 more! ]

Growth > 17mm + new shoot
Conclusion of the day : F & V grew at about the same rate while S grew the least.

Arrangement from fastest growing to slowest :S, A, D, F, V [ A & S not really important ]

THUS : Phosphate slows down the rate of growing, Nitrate increases the rate of growing but Potassium increases the growth rate even more.

  5. Pour the solution back into the bottle.
  6. Repeat steps 2 to 5 for the other 2 fertilizers.

Hello small fries ! :D
So very sorry I had to leave early just now but really, you all did well though. Farhana's update tells so. If there is a meet-up today, I won't be able to make it cause I'll be visiting my relative who's hospitalized recently. I will be available on friday however.
