Jap Pumpkin Trial

 

 

 

 

Jap Pumpkin Trial Log (Meringandan)

 

 

 

Day 1

 

The trial commenced on the 23rd October 2003 at Freda Garret’s property at Meringandan in Queensland, Australia.

A fenced area was provided to conduct the trial. The preparation of the seed mounds required the ground to be dug and potting mix applied and mixed in with the soil of each mound.

Prior to the charging session a pH and conductivity test was done on the bore water.

 

Readings

pH:

7.3

Conductivity:

1.8mS/cm

 

8 Jap Pumpkin seeds were placed in a 10 litre container and covered with water.

A 3050 Q Energy Spa and Orb were used to charge the water for a period of 35 minutes on low setting due to the high conductivity of the bore water.

After the charging session the seed was planted into the mounds with 4 seeds per mound and planted at a depth of 40 mm. After planting, each mound was identified according to the type of water treatment it was to receive.

Each mound was watered with 20 litres of water according to its water rating.

31st October 2003

Trial pumpkins monitored and it was observed that seeds in the groups had emerged.

Only one seed had struck in the uncharged seed and charged water group.

Each group was watered according to its treatment.

Readings of pH 7.8 and Conductivity of 1.8 mS/cm were recorded after the water had been charged.

19.03.2004 - Brix test readings and conductivity

Group A - uncharged seed, uncharged water

6.8 flesh

sap 16.5

9.4 mS/cm

Group B - charged seed, uncharged water

5 flesh

sap 10.3

8.1 mS/cm

Group C - uncharged seed, charged water

5.6 flesh

sap 8

6.9 mS/cm

Group D - charged seed, charged water

6.8 flesh

sap 13

6.8 mS/cm

Comparing each of the pumpkins, the riper the pumpkin the darker the colour of the flesh and the higher the brix level.

 

 

 

19.03.04

A Sample from each of the trial pumpkins was taken, cooked and mashed for a taste test.

Each taster was asked to rank the pumpkins in order of sweetness and texture.

The following is the majority preference (1 being the most preferred).

(A)

Uncharged seed, Uncharged water

3

(B)

Charged seed, Uncharged water

5

(C)

Uncharged seed, Charged water

4

(C2)

Uncharged seed, Charged water

2

(D)

Charged seed, Charged water

1

Pumpkins B, C & A were not quite mature.

Pumpkins C2 & D were ripe.

Pumpkin C2 was extra to the trial.

 

        

Note the colour difference between the pumpkins

 

 

 

 

Comparing the protein values of the pumpkins the Charged Seed, Uncharged Water (2) performed the best, followed by the Charged Seed, Charged Water (4).

 

The fat values of the pumpkins (2, 3 &4) which have had some form of charging treatment are lower in fat and much better than the uncharged seed uncharged water pumpkin.
