Question:
Given below are two statements:
Statement (I) : Nurse crops are perennial crops grown to help early establishment of annual crops for control of weeds.
Statement (II) : Cover crops are grown to protect the soil in order to manage soil erosion and soil fertility.
In light of the above statements, choose the most appropriate answer from the options given below.

In light of the above statements, choose the most appropriate answer from the options given below.
Show Hint
Remember that nurse crops act as temporary "protectors" for slow-growing seedlings, while cover crops act as "blankets" to protect and enrich the soil surface.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
This question tests definitions of supportive crop management systems, specifically comparing "Nurse crops" and "Cover crops."
Step 2: Detailed Explanation:
Let us analyze each statement:
Statement (I): Nurse crops are perennial crops grown to help early establishment of annual crops for control of weeds.
This statement is incorrect.
A nurse crop is typically a fast-growing annual crop planted alongside a slower-growing perennial crop.
The primary role of the nurse crop is to:
- Provide temporary shade and wind protection.
- Suppress weed growth during the early stages of the perennial crop's development.
For example, fast-growing oats are often sown as a nurse crop to protect young, slow-growing alfalfa seedlings.
The statement incorrectly reverses this relationship by stating that perennials are grown to nurse annual crops.
Statement (II): Cover crops are grown to protect the soil in order to manage soil erosion and soil fertility.
This statement is correct.
Cover crops are planted primarily to cover the soil surface rather than for immediate harvest.
They help prevent soil erosion by wind and water, suppress weeds, improve soil structure, and increase soil organic matter and fertility (especially when leguminous cover crops are used).
Step 3: Final Answer:
Statement (I) is incorrect, while Statement (II) is correct.
This corresponds to Option (D).

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.
