1. What does the useful water capacity of the soil mean? How is it calculated?
a. Total water content of the soil – water amount taken up by the plants
b. Total water storing capacity – water not available for the plants (dyed water)
c. Water pressure at the wilting point - evapotranspiration
2. What does the wilting point mean?
a. Strongly bound water in the soil, not available by the plants
b. Quantity of water available in the soil during the very hot sunny days
c. Value of the osmotic pressure, at which the capillary elevation of water can not compensate the water lost by transpiration
3. What are the most water demanding periods in the plant cultivation:
a. Germination, emergence
b. Shoot formation
c. Differentiation of flowers
d. Seed setting
e. Seed ripening
f. Re-shooting
4. How does the plant acclimate to the poor water supply?
a. Growth of the root surface for water uptake
b. Growth of the leaf surface for assimilation
c. Thickening of the cuticule
d. Development of less but larger flowers
e. Earlier flowering and ripening
f. Formation of climbing character, weak growth
5. Which species are not suggested to cultivate without irrigation under CE conditions?
a. poppy
b. fennel
c. lovage
d. thyme
e. rosemary
f. lemon balm
6. What are the connections between irrigation and other agricultural procedures? Which is right?
a. Irrigation may influence the use of nutrients
b. A higher number of individuals and a thicker plantation is possible in irrigated plant stand
c. The number of harvest, thus, the costs of cutting and transfer are growing in irrigated fields
d. Irrigation enables a less strict crop rotation
e. Introduction of irrigation technologies is a prerequisite of quality assurance.
f. Due to irrigation an enhanced crop health and drop of costs of plant protection is possible
7. What are the effects of irrigation to the accumulation of active substances?
a. Irrigation would alter the concentration of alkaloids.
b. Glycoside content of foxglove is not significantly influenced by water supply
c. Essential oil of peppermint is optimal if water supply is abundant
d. Essential oil content of hyssop will only be high enough under irrigated condition
e. An appropriate amount of precipitation during fruit formation is necessary for the accumulation of fatty oils
f. There is hardly any general answer for this, it depends on the species and the chemical compound
8. How does the irrigation method influence the quantity and quality of the drugs?
a. Alkaloid content of poppy capsules is growing by rain-type irrigation.
b. Alkaloid content of poppy capsules is dropping by rain-type irrigation.
c. Essential oil content of basil leaves is preserved by dropping irrigation
d. Essential oil content of basil leaves is decreased by dropping irrigation
e. Leaf of marjoram is polluted easily if irrigated by rain-type equipment
f. Leaf of marjoram is washed down if irrigated by rain-type equipment
g. Irrigation enhances formation of flower-heads in chamomile compared to vegetative parts
h. Irrigation may cause diseases in caraway and a negative effect on seed setting
