Agricultural Systems I. WS 2008/2009 Test A
TEST A
- Main purposes for primary use of plants
- Production of food
- Production of fabrice
- Farming system is defined as
- Horizontal and vertical integration of crop livestock, trees and aquaculture
- Norfolk four-course system is:
- Fallow field was omitted and replaced by fodder crops
- First crop was wheat followed by turnips and third barley with clover understown
- Horticulture Mixed Farming System is represented by:
- Farm size is small and has a diversified production pattern
- Cultivation of fruits, nuts and vegetables, partly irrigated
- Sparse (cold) Farming System is represented by:
- Limited cultivation of rye and oats, as well as for potatoes and some vegetables
- Short growing season, very low temperatures and poor soils
- Main objectioves of organic farming are:
- Production of healhty food under regulated procedure
- Development of soil fertility mechanical weed control
- Main steps of soil development are:
- Weathering of organic materials -možná
- Transition of unstable minerals into more stable ones
- Soil horizon O is described as
- Dark top horizon
- Layer with presence of high organic matter
- Gaseous phase (soil air) contains .... compare to atmospheric air
- Elevated amounts of oxygen and nitrogen
- Mineral solid soil portion consists of:
- Inert silica compounds
- Primary and secondary aluminosicilates
- What does it mean soil fertility:
- Ability of soil to create optimum conditions for plant growth
- Which main factors are required for plant growth
- Water, sun radiation, temperature, nutrients
- Nutriens uptake is caused by:
- Which elements belongs to major (macro) nutriens:
- N, P, K, Ca, Mg
- N, P, K, Ca, S
- Recommended sowing rate of winter wheat is:
- Which components belong among outputs of nutrient cycle
- Washing evaporation, plants uptake
- Which organism belong to pathogens:
- Salmonela, Clostridium, Mycotoxins, Leptospira
- Choose characteristics, which does not belong to the characterizition of the 1st group of cereals
- They create only spring forms
- To the cereals of IInd group belong:
- The average growing area of rye in Czech Republic is about
- The average yield of sugar beet roots in the Czech Republic is about:
- 40-50 t.ha -1 v prezentaci má 50-53
- Potatoes do not prefer
Lower temperatures during vegetation
- Fertile, black and brown soils
- Potatoes of the cooking type D are:
- Ridging of potatoes by the special ploughshare is made several times:
- From germination to the beginning of buds formation
- Average sugar content in the sugar beet root in the conditions of the Czech Republic is about:
- Oilseed rape is not used for production of:
- Winter oilseed rape is usually harvested:
- The best harvest time for the leaf drugs is
- Begining of the buds formation
- To the antidiabetics does not belong:
- Primary tillage is used to:
- Convention tillage comprises all tillage types that:
- Leave less than 15% crops residues on the soil surface after planting the next crop
- Leave less than 1100kg ha-1 of small grain residues through a critical erosion period
- Conversation tillage includes
- Mark shallow rooting crops
- Optimum of C:N ratio lies between
- Conservation methods of biological weed management involve
- Modifying the enviromental to retain or increase population of resident control agents and intesity the damage they inflicts on weeds
- Non-selective herbicide
- UV radiation is the light with wavelenght between:
- Long day plants:
- Require a relatively long day for the formation of infloresence
- Increase in vegetative growth when the days are short
- In the Czech Republic, predominant type of agriculture according to water supply is:
- Which crops can not be succesfully grown in potatoes production area?
- Main vectors for virus-born disceases are:
- Sugar beet does not prefer:
- Which chemicals are used in weed management?
- What does it mean physical weathering
- Use of different forces for rock disintegration
- Use of frost for rock disintegration - možná
- Colorado beetle is very important pest of:
- UV radiation
- Can not be seen (non-visible)
- Can be harmful to plant tissues and eyes
- Urban Based Farming System is represented by:
- Production of vegetables, in particular leafy vegetables
- Small livestock is usually grown there
- Minimum oil content in seed of oilseed rape should be:
- Enviromental importance of plants are:
- Sequestration of CO2
- Water reservoirs protection
- Positive effects of the weeds:
- Weeds can provide food for crop pollinators and pest bioregulators
