Question

Given below are two statements
Statement I: According to Willcox's agrobiology, amount of nitrogen absorbed by all kind of plant is 318 pounds/acre in single crop cycle.
Statement II: Willcox's inverse yield nitrogen law still hold good.
In light of the above statements, choose the correct answer from the options given below

• A. Both Statement I and Statement II are true
• B. Both Statement I and Statement II are false
• C. Statement I is true but Statement II is false
• D. Statement I is false but Statement II is true

Hint:

Willcox's "318 lbs N/acre" is a famous constant in classical agrobiology (Statement I). However, his "inverse yield" law has been disproven by modern crop physiology (Statement II).

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
O. W. Willcox formulated laws of agrobiology that define the relationship between plant nutrients, crop genetics, and maximum potential yield.

Step 2: Detailed Explanation:
Let us analyze both statements:
- Statement I: Willcox proposed that the maximum quantity of nitrogen that can be absorbed by any crop species during a single growing season is a constant, equal to $318\text{ pounds per acre}$ (which corresponds to 100 units of growth, or "Baule units" of nitrogen).
This is a core tenet of Willcox's quantitative agrobiology. Therefore, Statement I is true.
- Statement II: Willcox's "inverse yield nitrogen law" states that the yield of a crop is inversely proportional to the nitrogen percentage in its dry matter.
Modern agricultural science and extensive empirical testing have demonstrated that this law does not hold true under diverse field conditions.
Genetic improvements, modern fertilization methods, and physiological variations have disproven this inverse relationship.
Therefore, Statement II is false.
Consequently, Statement I is true but Statement II is false.

Step 3: Final Answer:
Statement I is true but Statement II is false.
