MATERIAL PREPARATIONS:
(1) 5 recycle plastic pots that can fit in about 5 litres of soil.
~ Make holes for drainage at the pot bottom.

(2) The team need to collect only one type of soil which is about pH7 (collect about 6 litres of soil).
Jicama grows better on soil contain sandy texture or not so easily compacted like clay.

(3) Conduct soil pH test and soil texture triangulation for soil texture type for the report.
~ Dry at least 500 gram of soil.
~ Before air dry outside the lab, take the wet soil weight measurement for each soil.
~ Measure the dry soil weight after completely dried. Then keep dry for further analysis (nutrient and heavy metal).

(4) Provide the same amount of water for each watering session (tap water).
Example : 500 ml water for each pot/persession or once a day.
Pot 1: Your control for this experiment. Water everyday.
Pot 2: 1st and 2nd week water everyday; 3rd and 4th week water alternate days.
Pot 3: 1st and 2nd week water everyday; 3rd and 4th week water twice perweek.
Pot 4: 1st and 2nd week water every day; 3rd week water twice perweek; 4th week water once only.
Pot 5: 1st and 2nd week water every day; 3rd week & 4th week water once only.

(5) Ruler/measurement tape
~ to record the growth of the plant.

PROCEDURE:

(1) Air dry some of soil samples (about 500gram) for heavy metal and macronutrient analysis.
~ Before soil are dried outside of the lab, take the measurement of wet soil weight.
~ The week after if the soil is totally dried up, take the measurement of dry soil weight.
~ Keep soil dry until further analyse.

(2) Measure the empty pot. Keep record.

(2) Fill up the pot with soil and cover the seed with soil (3cm deep). Measure the weight of the soil and pot. Keep record. 
~ After 3rd week measure each pot and soil each time before you water your plant, so you can estimate the loss rate of water from different type of soil (Create a research question from this and observation data interpretation from this).

(3) For 1 pot sow 10 seeds each and space them apart from each other.

(4) After a month old, dig out 3 whole plant from each pot including the root carefully. Measure the length of the whole plant from root to shoot, root length and shoot length. Weigh the weight of the whole plant clean without soil, plant wet weight (fresh harvested state) and after plant in dried state (plant dry weight).Keep record.

(5) Count the number of nodules form at a month old seedlings. Compare between different watering frequency.

(6) After a month, analyse the nutrient content of the soil.

OBSERVATION RECORD:

(1) Germination rate for each pot.
(2) How long does seeds start to sprout an emerge from the soil for each pot.
(3) Mortality/Survival rate of the plant growth.
(4) Growth of the plant of each plant for every week.
(5) Any deficiency symptoms such as yellowing of the leaves.
(6) Compare the nutrient and heavy metal amount between different soil textures.
(7) Moisture content.
(8) Length of whole plant, root and shoot part separately at a month old. Wet weight and Dry weight of whole plant without any soil attach.
(9) Number of nodules form at a month old seedlings.

RESEARCH QUESTIONS:


(1) Among five frequency of watering which produce more root growth for jicama plant.
(2) How does moisture content of each type of watering frequency affect jicama growth.
(3) How does moisture affect number of nodules form on jicama root.
(4) Nutrient availability for jicama growth from each soil texture.
(5) Is the soil contaminated with heavy metal.
(6) Which soil is most fertile to grow jicama productively.
