Multiple Choice Questions

1. Which one of the following condition is not essential to grow maize?

(a) High temperature

(c) Low temperature

(b) Humidity

(d) Rainfall

Soln:

The answer is (c) Low temperature

Explanation:

Maize is grown in a warm and tropical climate. The optimum temperature for growing maize is between 180c -27 0c in day and 140-150c in the night. Hence a cold climate is not essential to grow maize.

Soln:

The answer is (b) drip system

Explanation:

Pulley system is traditional irrigation methods where water is lifted from wells or other water sources and crops are watered. This is done by using the pulley chain and human labour or animals.

The perpendicular pipes, having rotating nozzles on top, are joined to the main pipeline at regular intervals. When water is allowed to flow through the main pipe under pressure with the help of a pump, it escapes from the rotating nozzles. It gets sprinkled on the crop as if it is raining

Lever system is traditional irrigation methods where human or animals are used to lift the water from its source. This is a less efficient irrigation method.

29. For discussion Despite being one of the growing economies, our country still has a large section of the population going hungry and malnourished. Do you think an efficient crop production mechanism is the only solution to this? Discuss in the class what else needs to be done to root out hunger and malnutrition from our country.

Soln:

India, a growing economy with agriculture is the main contributor to its growth. Agriculture is the science of cultivating plants, animals and other life forms for food and other sources, Despite large production of crops by agricultural practices, people still go hungry and malnourished. This happens because of inefficient crop production and management. In India, an increase in production of food grains has been observed from 1960 to 2004. With efficient management, crop production can be enhanced and improved to feed the country’s poor. A few steps in this direction can be:

1. Selection of high field seeds for planting the seeds with increased yield and reduced growth period.

2. Management of crop production: The financial aspects of agriculture should be made more approachable to farmers at all levels.

3. Information regarding the use of chemicals, manures, cropping patterns, nutrient quality and irrigation facilities should be discussed and propagated among farmers.

4 Protection of crops: The agricultural produce should be shared efficiently to reduce the microbial or other organisms from infesting the produce. Pest and weed control measures should be adopted.

A large number of crops get spoiled during storage by different living and non-living factors. Living factors include rodents, microbes and insects. Non-living factors are moisture, temperature and hygiene of storage place. Keeping these factors in mind, we can reduce the economic losses, increase the marketability and feed the country’s poor.

30. Terms related to the agricultural practice are given below. Rearrange them in the correct sequence.

harvesting, sowing, manuring, tilling and ploughing, irrigation, de-weeding.

Soln:

The correct sequence of agricultural practices are

i) Tilling and Ploughing

ii) Sowing

iii) Manuring

iv) Irrigation

v) Weeding

vi) Harvesting

i) Tilling and ploughing:

One of the most important tasks in agriculture is to turn the soil and loosen it. This allows the roots to penetrate deep into the soil. The loose soil allows the roots to breathe easily even when they go deep into the soil. The process of loosening and turning of the soil is called tilling or ploughing.

ii) Sowing:

After tilling and ploughing healthy seeds are collected and they are sown into considerable depth.

iii) Manuring

Plants are manured with humus which improves the texture of the soil and replenishes nutrients in the soil.

iv) Irrigation

Irrigation helps to water the plants regularly which will help in keeping the moisture of plants.

v) Weeding

Weeds are removed before they get matured as they compete with crops for water, nutrients and sunlight.

vi) Harvesting

Cutting and gathering matured crops is known as harvesting. Harvesting can be done manually as well as by using harvesters.
