Questions Related to improved methods of agriculture
Fresh crop has more__________________
-
Moisture
-
Impurities
-
Weed
-
Stones
- The fresh crop has more moisture. Hence, they should be dried in the sun to reduce moisture before storage because if freshly harvested grains are stored they may get spoilt or attacked by organisms.
Large scale storage of grains is done in _______________
-
Plastic bags
-
Silos
-
Pouches
-
None of these
- Insects in stored grain can cause much damage. The farmer may lose up to a third of the stored grain.
- Large scale storage of grains is done in silos and granaries to protect them from pests like rats and insects.
Which system is a boon in regions of poor availability of water?
-
Sprinkler system
-
Rahat
-
Drip system
-
Dhekli
- Drip irrigation is an irrigation method that saves water and fertilizer by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters.
The modern method of irrigation is___________
-
Sprinkler system
-
Drip system
-
Both A and B
-
None of these
- The supply of water to the crops at different intervals is called irrigation. Lakes, rivers, dams, canals, etc. are the sources of water for irrigation.
- Various traditional ways of irrigation are pulley system, chain pump, dhekli, and Rahat.
- Traditional methods are cheaper but they are less efficient as compared to modern methods. The modern methods of irrigation include sprinkler systems, drip systems, etc.
- In the sprinkler system, water is sprinkled on the crop by using a pipe and nozzle system. It resembles raining. In the drip system, waterfalls drop by drop just at the position of the root.
Storage of food for longer duration should be prevented from_______________
-
Humans
-
Sand
-
Rats
-
Jute
- The storage of food crops is an important step of agricultural practices. If the crop grains are to be kept for a longer time, they should be prevented from moisture, insects, rats, and microorganisms.
Small scale storage of grains is done in_______________________
-
Silos
-
Granaries
-
Buckets
-
Jute bags
- Storage of food crops is an important step of agricultural practices as harvesting because if the grains are not stored properly it may get spoilt or attacked by insects or rats or microorganisms.
- Large scale storage of grains is done in granaries or silo. Farmers store their dried grains in jute bags or metallic bins.
The heat of dump grain in storage occurs due to .......... content and growth of moulds.
-
High moisture
-
Low moisture
-
Biotic
-
None of the above
Heating of stored grains results due to the high moisture content in the grains. The grains heat up the water content present in the grain due to thier pre existing temperature which attracts more moisture leading to the growth of microbes in the grains or germinate the seeds thus destroying the yield.
Preventive and control measures adopted for the storage of grains include
-
Strict cleaning
-
Proper disjoining
-
Fumigation
-
All of the above
Most important aspect of agriculture is proper storage of harvested
grains and other agricultural produce. Proper storage is necessary to
get seasonal foods regularly throughout the year. The godowns and
stores should be properly clean, storage bags should be fumigated or
treated with insecticides or pesticides. In India, the loss due to
improper storage of grains is about 9% annually. So, the correct answer is 'All of the above'.
The grains are stored mainly for purpose _____
-
To make use of agricultural products as sowing grains for next year
-
To make the food stuff regularly available throughout the year
-
To maintain the price rate of agriculture product
-
All of the above
How temperature causes damage to a food material?
-
It affects the growth of casual organisms
-
Alters the enzyme action
-
Both A and B
-
None of the above
Food can be spoiled when temperatures are not controlled because high temperature give way for the growth of bacteria and excessive heat increases the rate of enzyme reactions. Exposing food to clod temperature also damages the food.
