Show Hint
Hundeshogen = Ratio of actual/normal. Von Mantel = Simple Volume/Rotation. These are the two "Grandfathers" of yield math.

The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
The question asks for the originator of a yield regulation formula that relies on the ratio between actual volume and increment. This is a classic concept in forest management and sustainability.
Detailed Explanation:
• Concept: Yield regulation aims to ensure that the amount of wood harvested does not exceed the forest's ability to regenerate. One way to do this is by assuming that the yield should be proportional to the increment.
• Hundeshogen's Formula (1826): Hundeshogen proposed that the yield ($Y$) of an actual forest should bear the same proportion to its actual volume ($V$) as the increment ($i$) of a normal forest bears to its normal volume ($V_n$). \[ Y = \frac{i}{V_n} \times V \] This was one of the earliest mathematical approaches to sustainability.
• Comparison: - Von Mantel (1852) introduced a simpler formula based on volume and rotation ($Y = 2V/R$), assuming a normal distribution of age classes. - Brandis is famous for the Brandis Method used in teak forests of Burma (Myanmar). - Champion and Seth are famous for forest type classification, not yield formulas.
Step 2: Final Answer:
The formula based on the relationship between volume and increment was introduced by Hundeshogen in 18

Statement (I): Anogeissus latifolia is worked only as a component species of mixed forests as coppice-with-standards.
Statement (II): Terminalia arjuna tree is not a regular component of forest stand and is usually worked under selection and coppice with standards.
Choose the correct answer from the options given below: - The most important single factor affecting natural regeneration of Shorea robusta is the time lag between the falling of seed and the commencement of the ________.
- Read the following statements and choose the correct answer about silvicultural system/s adopted for the management of Shorea robusta:
Statement (I): Under clear felling system, a rotation age is fixed and the entire area clear felled and the crop is of uniform age.
Statement (II): Selection system is adopted for areas which are badly eroded and where regeneration is problem and regeneration is obtained by natural means, which may be supplemented by planting.
Statement (III): In coppice with standards system, a few standards are retained and the other trees above the exploitable diameter are clear felled and regeneration is obtained by means of coppice.
