Question

Given below is a set of statements about 'Field counts' conducted during the inspection of the seed production field. Select the group of the most appropriate statements -
(A) It is necessary to take a minimum of 5 counts for up to 2 ha seed production field and one additional count for every additional area of 2 ha or part there.
(B) For a seed production area of 6 to 8 ha, the minimum number of counts to be made is 8.
(C) Number of plants or heads per count in sunflowers is 1100.
(D) Number of plants or heads per count in soybean is 1000.
Choose the correct answer from the options given below :

• A. (A), (B) and (C) only.
• B. (A), (B) and (D) only.
• C. (A), (C) and (D) only.
• D. (B), (C) and (D) only.

Hint:

Remember the seed certification standard rules for field counts:
- Plot size count increments: 5 counts for up to 2 ha, plus 1 count for every additional 2 ha.
- Plants per count: 100 plants for low-density/wide-spaced crops (Sunflower), and 1000 plants for high-density/close-planted crops (Soybean, wheat).

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Field inspection is a critical step in certified seed production to evaluate the seed crop's genetic purity, disease incidence, and physical contamination.
Inspectors take a series of random, representative "field counts" throughout the plot to assess these parameters objectively under the Indian Minimum Seed Certification Standards (IMSCS).

Step 2: Detailed Explanation:
Let us evaluate each technical statement regarding field counts:
- (A) Minimum of 5 counts for up to 2 ha and one additional count for every additional 2 ha: This is correct.
Under IMSCS rules, for any seed crop field measuring up to 2 hectares (5 acres), a minimum of 5 random counts must be taken.
For every additional 2 hectares or part thereof, 1 additional count must be added.
- (B) For a seed production area of 6 to 8 ha, the minimum number of counts is 8: This is correct.
Using the formula from Statement (A):
- Up to 2 ha = 5 counts.
- 2 to 4 ha = 6 counts.
- 4 to 6 ha = 7 counts.
- 6 to 8 ha = 8 counts.
- (D) Number of plants per count in soybean is 1000: This is correct.
For close-planted, high-density crops like soybean, each random count must encompass a minimum of 1000 plants to be statistically representative.
- (C) Number of plants per count in sunflowers is 1100: This is incorrect.
Sunflower is a wide-spaced, low-density crop.
Under certification standards, each random count in a sunflower field requires evaluating only 100 plants/heads (not 1100).
Therefore, only statements (A), (B), and (D) are correct, which corresponds to Option (B).

Step 3: Final Answer:
The group of most appropriate statements is (A), (B) and (D) only.
