17. Consider the following statements: [U.P. Lower Sub. (Pre) 2013]

1. Highest production of wheat in India is obtained from the state of U.P.

2. Cropping pattern occupying the highest area it U.P. is rice-wheat.

3. An extension worker does not need political competency.

4. The most critical stage of irrigation in wheat is flowering stage.

Which of these statements are correct?

(a) Only 1 and 2

Correct Answer: (d) Only 1, 2 and 3

Solution:According to Economic Survey 2022-23 in the year 2021-22 (4th A.E.) data, the largest producer of wheat is Uttar Pradesh. Rice and wheat occupy the largest area in cropping pattern in U.P. Irrigations are given at critical stages of growth. These stages include C.R.I. stage (Crown root initiation) in this irrigation is done after 20 to 25 days of sowing to promote tillering. CRI stage is the most critical stage for irrigation in wheat because any shortage of moisture at this stage results in less tillering, formation of small eartheads and great reduction in yield.

18. 'Triticale' is a cross between which of the following? [U.P.P.C.S. (Mains) 2014]

(a) Barley and Rye
(b) Wheat and Oat
(c) Wheat and Barley

It's used to make a variety of food products. It's also grown for its ability to tolerate difficult soils, drought, cold, and disease.

19. The statements are given below, labelled as Assertion (A) and Reason (R). In the context of these two statements, select the correct answer from the codes given below. [M.P.P.C.S. (Pre) 2020]

Assertion (A): Punjab, Haryana, Uttar Pradesh are major wheat producing states of India.

Reason (R): The well drained fertile soil, 10° -15°C temperature during winter and about 75 cm annual average rainfall are necessary for wheat production.

Codes:

(a) Both (A) and (R) are true, and (R) is the correct explanation of (A)
(b) Both (A) and (R) are true, but (R) is not the correct explanation of (A)

(d) Both (A) and (R) are false

Correct Answer: (b) Both (A) and (R) are true, but (R) is not the correct explanation of (A)

Solution:Punjab, Haryana, Uttar Pradesh are major wheat producing states of India. So the assertion is true. The well drained fertile soil, 10º-15°C temperature during winter and about 75cm annual average rainfall are necessary for wheat production. From this point of view the reason is also true. But reason (R) is not the correct explanation of assertion (A).
