Agriculture

What did the ‘Green Revolution’ actually revolutionize?

• Business Culture

• Tissue Culture

• Agriculture

• Tradition and culture

Which of the following was a part of the green revolution strategy?

• High yielding variety seeds

• Chemical fertilizers and pesticides

• Irrigation

• All the above

In Green Revolution the traditional farming techniques were replaced by ______________________ and the farming became more scientific.

• Seeds

• Machineries

• Carts

• Old methods

The success of green revolution depends upon the availability of

• high yielding variety of seeds

• adequate facilities of irrigation

• chemical fertilizer and pesticides

• all of these

Which of the following best describes IPM?

• Spraying broad-spectrum chemical pesticides as the first line of defense 
• Complete elimination of all chemical pesticides
• Implementing a variety of cultivation and biological techniques and only spraying pesticides as a last resort
• Utilizing only trap cropping and crop rotation

Traditional farmers grow several crops on the same plot of land in a practice referred to as

• monoculture
• polyculture
• aquaculture
• slash and burn

Repeated application of irrigated water in dry climates leads to...

• a drop in productivity of the land by more than 10%, leading to desertification
• a build up of nutrients, leading to increased levels of erosion
• a build up of salts in the soil, leading to salinization
• decreased phosphorus and nitrogen, leading to eutrophication

The use of synthetic fertilizers can increase crop yield, but also

• destroy nitrifying bacteria in the soil
• increase nutrient runoff into nearby surface waters
• slow the release of organic nutrients from compost
• increase fish populations in nearby streams

Which of the following best describes a genetically modified organism (GMO)?

• An organism that has been selectively bred for the best traits
• An organism that contains foreign DNA
• An organism that is produced after exposure to a mutagen.
• An organism that has been cloned

Which of the following is NOT a key component of organic agriculture?

• Using genetically modified seeds.
• Applying manure as fertilizer.
• Integrated Pest Management
• Crop Rotation
