Question

Growth factor necessary to produce yield that is 50% of the difference between maximum possible yield and yield before that unit was applied was given by ------
(A).Mitscherlich & Bray
(B).Mitscherlich & Baule
(C).Baule only
(D). Baule, Arnon & Bray
Choose the correct answer from the options given below:

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

Hint:

The Baule unit represents a 50% yield increment.
- 1 Baule unit = 50% yield.
- 2 Baule units = 75% yield.
- 3 Baule units = 87.5% yield.
This logarithmic progression is a key concept in soil fertility exams.
