Question

Match List I with List II:
A. Bray
B. Mitscherlich
C. O.W. Wilcox
D. Parker
Match with the following:
I. Law of diminishing return
II. Per cent yield concept
III. Nutrient Index
IV. Inverse Nitrogen-Yield concept
Choose the correct answer from the options given below:

• A. A-I, B-IV, C-III, D-II
• B. A-III, B-II, C-I, D-IV
• C. A-II, B-I, C-IV, D-III
• D. A-IV, B-III, C-II, D-I

Hint:

Bray: percent yield concept.
Mitscherlich: law of diminishing returns.
Wilcox: inverse N-yield concept.
Parker: nutrient index.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Different scientists contributed to soil fertility concepts.
We need to match each scientist with their contribution.

Step 2: Key Formula or Approach:
No specific formula.
Need to know the contributions of each scientist.

Step 3: Detailed Explanation:
Bray: Per cent yield concept (A-II).
Mitscherlich: Law of diminishing return (B-I).
O.W. Wilcox: Inverse Nitrogen-Yield concept (C-IV).
Parker: Nutrient Index (D-III).
Thus, A-II, B-I, C-IV, D-III is the correct matching.

Step 4: Final Answer:
The correct matching is A-II, B-I, C-IV, D-III.
Hence, the correct option is (C).
