Which design is mostly preferred for green house experiment of agroforestry species?
Show Hint
- Controlled environment (Greenhouse/Lab) \(\rightarrow\) Completely Randomized Design (CRD)
- Field trials with a single gradient (Slope/Water) \(\rightarrow\) Randomized Block Design (RBD)
- Field trials with a single gradient (Slope/Water) \(\rightarrow\) Randomized Block Design (RBD)
Updated On: Jul 10, 2026
- RBD
- CRD
- Split-plot design
- Latin square design
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Experimental design selection in forestry research depends on the homogeneity of the environmental factors in the testing area.
Step 2: Detailed Explanation:
- In greenhouse environments, factors like temperature, humidity, lighting, and soil substrate are highly controlled and uniform across the space.
- When the experimental units are homogeneous (having no directional fertility or environmental gradients), the Completely Randomized Design (CRD) is the most efficient and preferred statistical design.
- Randomized Block Design (RBD) and Latin Square Design are used when there are one or two known gradients of environmental variation (such as in field trials).
- Split-plot design is used when treatments require different sizes of experimental plots.
Step 3: Final Answer:
The design mostly preferred for homogeneous greenhouse experiments is CRD.

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.
