- 1Catch CropA fast growing crop grown between two main crops e.g. kale
- 2Crop RotationThe growing of crops in a definite sequence
- 3Biological ControlThe introduction of a predator,parasite or infectious agent
Eg; Ladybirds could be introduced to kill greenfly - 4What guarantees come with certified seedGuarantees 85% germination, minimum 98% purity, free from wild oats and treated with an insecticide and fungicide
- 5Soil type and Climate for barley-Brown earth soils
-deep sandy loams
-Ph 6.5
-requires a steady supply of moisture while growing and dry weather for ripening and harvest - 6Seedbed prep for barley-plough in autumn
-harrow in spring to produce a fine seedbed - 73 modes of HerbicidesContact
Translocated
Residual - 8Powdery mildewFungal disease which forms grey-White patches. Dust like particles in the air are spores created by the fungus
- 93 modes of FungicidesEradicant
Protective
Systemic - 10How do you prevent or eradicate pesticides?-Usually sprayed on crops
-kills pest on contact
-or by eating leaf sprayed by herbicide
-eg. Slug pellets - 11Characteristics Winter variety Barley seed-frost resistant
-sown September to Novemeber
-harvested mid-July
-higher yield due to longer growing season - 12Characteristics Spring variety Barley seed-non frost resistand
-sown February to April
-harvested August
Lower yield due to shorter growing season - 13Sowing-sow as early as weather permits
-sowing rate of 150kg per ha
-roll seedbed - 14What causes failure of seeds to germinate-not certified
-soil waterlogged/cold
-attacked by disease or pest
-soil to dry
-soil compacted(low air content) - 15Indirect Control (Definition)Aim is not to kill pest,disease or pest but to reduce the problem.
- 16Direct Control(Definition)Use of chemicals to directly kill the problem.
- 17Indirect Control MethodsCrop Rotation
Growth Encouragement
Sowing Resistant Varieties
Harvesting Without Delay
Stubble Cleaning - 18Method of Weed ControlUse Crop Rotation and Stubble Cleaning
Identify and use selective Herbicide
Spray early when weed is soft - 19Tram LinesParallel lines left unsown in crop.
Used for spraying crops and spreading fertiliser - 20Barley yield7-8 tonnes p/ha
3-4 tonnes p/a - 21StorageDry to 14% moisture or use acid treatment.
- 22When do you harvest Barley? Judging the plant not time of year?Grain is dry and hard and moisture content is low as possible.
