Agriculture: CUET Mock Test - 3 - Question 5

Which of the following is not a cause of disruption of a pest's life-cycle?

Detailed Solution for Agriculture: CUET Mock Test - 3 - Question 5

Clean cultivation is often recommended as a way to eliminate shelter and/or overwintering sites for pest populations. Simply tilling or ploughing a corn field before winter may disrupt a pest's life-cycle by causing mechanical injury, by increasing exposure to lethal cold temperatures, by intensifying predation by birds or small mammals, or by burying the pests deep beneath the soil surface. Populations of corn earworms and European corn borers have been greatly reduced in recent years by community-wide efforts to plough under corn stubble after harvest.

The practice of growing two or more crops simultaneously in a fixed pattern is known as

Detailed Solution for Agriculture: CUET Mock Test - 3 - Question 12
  • Intercropping - Growing of two or more crops simultaneously in a fixed pattern is known as inter-cropping. A few rows of one crop and then a few rows of another crop are grown.
  • Mixed cropping - It simply means growing two or more crops simultaneously on the same piece of land. Example: Growing a leguminous crop with a non-leguminous crop. Therefore, if the non-leguminous crop cannot take nitrogen from the soil, the other leguminous crop consumes it as it can take nitrogen available in the soil. Example: Wheat (non-leguminous crop) + gram (leguminous crop) or wheat (non-leguminous crop) + mustard (leguminous crop).
  • Crop rotation - This is a practice of growing a series of dissimilar crops in the same area in sequential seasons for various benefits to avoid build up of pathogens or pests that often occurs when one type of species is continuously cropped.

Detailed Solution for Agriculture: CUET Mock Test - 3 - Question 19

Weeds are unwanted plants which grow in gardens, lawns etc. Weeds are undesirable and some weeds create nuisance because they have thorns and prickles while some release chemicals which are toxic and cause skin irritation. If eaten, they can be hazardous. They crowd out and restrict light from reaching more desired crops. They also take away the nutrients available for the desired crops in the soil.
Therefore, weeds should be removed from the crop field as early as possible because weeds compete with the main crop for their survival.

Detailed Solution for Agriculture: CUET Mock Test - 3 - Question 30

In agriculture, broadcast seeding is a method of seeding that involves scattering seed, by hand or mechanically, over a relatively large area. Broadcast seeding is of particular use in establishing dense plant spacing, as for cover crops and lawns. In comparison to traditional drill planting, broadcast seeding will require 10–20% more seed. It's simpler, faster, and easier than traditional row sowing. Broadcast seeding works best for plants that do not require singular spacing or that are more easily thinned later.

Detailed Solution for Agriculture: CUET Mock Test - 3 - Question 35
  • Precipitation includes all water which falls from atmosphere such as rainfall, snow, hail, fog and dew.
  • Following a period of dormancy, germination is the process through which a plant emerges from a seed or spore.
  • The amount of water vapour carried by the atmosphere is known as atmospheric humidity.
  • A water-air mixture's relative humidity is a measurement of the amount of water vapour present in relation to the highest amount possible.
Agriculture: CUET Mock Test - 3 - Question 36

Which of the following options is correct with respect to the statements given below?
Statement A: In all the surface methods of irrigation, water is either ponded on the soil or allowed to flow continuously over the soil surface for the duration of irrigation.
Statement B: Border strip irrigation is a controlled surface flooding method of applying irrigation water.

Detailed Solution for Agriculture: CUET Mock Test - 3 - Question 36
  • In all the surface methods of irrigation, water is either ponded on the soil or allowed to flow continuously over the soil surface for the duration of irrigation. Although surface irrigation is the oldest and most common method of irrigation (90% adopted in worldwide), it does not result in high levels of performance.
  • Border strip irrigation (or simply border irrigation) is a controlled surface flooding method of applying irrigation water. In this method, the farm is divided into a number of strips. These strips are separated by low levees (or borders). Water from the supply ditch is diverted to these strips along which it flows slowly towards the downstream end and in the process it wets and irrigates the soil.

(b) Lowering of the income of the watershed community
(c) Mitigation of droughts and floods

Detailed Solution for Agriculture: CUET Mock Test - 3 - Question 38

Watershed management not only increases the production and income of the watershed community, but also mitigates droughts and floods and increases the life of the downstream dam and reservoirs.

Agriculture: CUET Mock Test - 3 - Question 39

Which of the following statements most accurately describes why regions near the equator are warmer than those far away?

Detailed Solution for Agriculture: CUET Mock Test - 3 - Question 39
  • Locations close to the equator are often warmer than locations farther from it. This is so because sun rays fall vertically on the equator and slant in temperate and polar zones, respectively.
  • Compared to the slanting rays, the vertical rays are more concentrated across a smaller region. Once more, the vertical rays travel through the atmosphere for a shorter distance before touching the surface of the planet. As a result, the temperature increases as latitude decreases and vice versa.
