B Correct answer
Explanation

Keeping the land fallow after harvesting a major crop helps in replenishing lost nutrients of soil naturally.

Multiple choice

What is broadcaster?

  1. It is an instrument to uproot weeds.

  2. It is an instrument to spray pesticide on diseased plants.

  3. It is an instrument to harvest the crop.

  4. It is an instrument to sow seeds in levelled soil.

  5. It is an instrument to irrigate the crop field.

D Correct answer
Explanation

Broadcaster is an instrument to sow seeds in levelled soil.

Multiple choice

Which of the following are not the purposes of ploughing a field? (a) It enhances the fertility of soil. (b) It loosens up the soil. (c) It converts the type of soil into another. (d) It helps the root of the plant breathe easily. (e) It increases moisture in the soil.

  1. Only (a) and (b)

  2. Only (b) and (c)

  3. Only (a) and (d)

  4. Only (d) and (e)

  5. Only (c) and (e)

Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Ploughing of field does not change the type of soil. The moisture in the soil is the result of irrigation.          

Multiple choice

Deep litter and cage systems are associated with

  1. dairy development

  2. pig farming

  3. poultry growing

  4. none of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Deep litter and cage systems are two common housing methods used in poultry farming for egg and meat production. The deep litter system allows birds to move freely on bedding material that accumulates, while cage systems house birds in individual wire compartments for better space utilization and easier management.

Multiple choice

Which of the following is not a feature of intercropping?

  1. Both the crops can be easily harvested and threshed separately.

  2. Pesticides can be easily applied to the individual crop.

  3. It involves set patterns of rows of crops.

  4. Seeds of two crops are mixed before sowing.

  5. It aims to increase productivity per unit area.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

This is the correct option as this is not a feature of intercropping. Seeds of two crops are mixed before sowing in mixed cropping.

Multiple choice

There are different basic practices that a farmer performs while crop production. They are irrigation, storage, harvesting, preparation of soil, application of manures and fertilizers, weeding and sowing of seeds, but not essentially in the same order. Which among the above practices is in general the last step?

  1. Storage

  2. Harvesting

  3. Sowing of seeds

  4. Weeding

  5. Irrigation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Storage is the last step in crop production.

Multiple choice

Which among the following is not a method to conserve land?

  1. Afforestation

  2. Check on overgrazing

  3. Regulated use of fertilizers

  4. Overuse of fertilizers and chemical pesticides
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Overusing fertilizers and chemical pesticides degrades soil quality, reduces fertility, and harms beneficial organisms in the ecosystem. True land conservation methods include afforestation, controlled grazing, and regulated chemical use to maintain long-term land productivity.

Multiple choice

Mulching helps in

  1. moisture conservation

  2. weed control

  3. improvement of soil structure

  4. increasing soil fertility
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mulching helps in moisture conservation. As these mulches slowly decompose, they provide organic matter which helps keep the soil loose.

Multiple choice

What is/are the disadvantage(s) of ploughing in arid and semi arid zones?

  1. There is a loss of soil water.

  2. Soil particles become smaller.

  3. Soil organisms are exposed.

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In arid and semi-arid zones, ploughing exposes moist soil to hot, dry winds causing rapid evaporation and loss of critical soil water. This is the primary disadvantage as water is the limiting factor. While soil organisms are exposed and particles may break down, the water loss is the most significant negative impact in water-scarce regions.

Multiple choice

To prevent the soil from being blown away after harvesting and before raising the next crop, the farmers should

  1. grow cover crops

  2. build embankments

  3. practice contour farming

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

After harvesting and before raising the next crop, the field lies bare. The wind blows off the top soil at that time. Thus, to prevent the soil from being blown away, the farmers grow cover crops such as grass and creepers.

Multiple choice

Which of the following is not efficient in weed control?

  1. Proper seedbed preparation

  2. Untimely sowing of crops

  3. Use of resistant crop varieties

  4. Summer ploughing system
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Timely sowing is crucial for weed control as it allows crops to establish before weeds can compete. Proper seedbed preparation, using resistant varieties, and summer ploughing are all effective weed control methods. Untimely sowing gives weeds a competitive advantage.

Multiple choice

Weeds should be removed from a crop field as early as possible, because

  1. they compete for food, space and light with the main crop.

  2. they take up nutrients from the soil, leaving fewer nutrients for the main crop.

  3. they reduce the yield of the main crop.

  4. all of the of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Weeds are unwanted plants that compete directly with crops for essential resources - nutrients from soil, space for growth, and sunlight for photosynthesis. This competition reduces the main crop's yield. Early removal is critical because weeds grow faster and can establish dominance quickly. All three effects (competition for food/space/light, nutrient depletion, yield reduction) occur simultaneously.
