Which of the following is considered the most significant abiotic stress factor limiting crop production in dryland regions?

Mulching is a widely adopted practice in dryland agriculture primarily to achieve which of the following?

Match the dryland agriculture problem in List I with its description in List II.

List I (Problem)	List II (Description)
1. Soil Erosion	P. Prolonged period of abnormally low rainfall, leading to water deficit.
2. Drought	Q. Loss of fertile topsoil due to the action of wind or water.
3. Low Soil Fertility	R. Accumulation of soluble salts in the upper soil profile, hindering plant growth.
4. Salinity	S. Insufficient essential plant nutrients in the soil, affecting crop vigor.

Contour bunding is a water conservation technique primarily effective in:

Why are crops like millets (e.g., sorghum, pearl millet) often preferred for cultivation in dryland regions?

Consider the following pairs of dryland water conservation techniques and their primary principles:

1. Conservation Tillage: Minimizing soil disturbance to retain crop residues.
2. Rainwater Harvesting: Capturing and storing precipitation for later use.
3. Agroforestry: Integrating trees with crops/livestock to enhance microclimate and soil health.
4. Terracing: Creating level steps on steep slopes to reduce runoff velocity and erosion.

How many of the above pairs are correctly matched?

What does 'in-situ' water harvesting refer to in dryland agriculture?

One of the major socio-economic problems associated with dryland agriculture is:

Which tillage practice is characterized by leaving at least 30% of the soil surface covered with crop residue after planting?

The primary benefit of selecting short-duration crop varieties for dryland farming is to:

Match the water conservation technique in List I with its primary benefit in List II.

List I (Technique)	List II (Benefit)
1. Mulching	P. Reduces soil erosion and retains moisture on slopes by planting different crops in alternating bands.
2. Contour Farming	Q. Breaks hardpan layers in the soil, improving water infiltration and root penetration.
3. Deep Tillage	R. Slows down surface runoff and increases the time for water absorption into the soil.
4. Strip Cropping	S. Minimizes evaporation from the soil surface and suppresses weed growth.

Choose the correct match:

Dry farming is typically practiced in areas receiving an annual rainfall of less than:

The problem of 'hardpan' formation in dryland soils primarily leads to:

Which of the following is an 'ex-situ' water harvesting method?

Arrange the following steps for effective dryland watershed management in a logical sequence:

I. Identification and prioritization of problem areas.
II. Implementation of soil and water conservation measures.
III. Monitoring and evaluation of implemented interventions.
IV. Participatory planning and resource assessment.

What is the primary objective of 'run-off farming' in dryland regions?

In dryland agriculture, the practice of frequent shallow tillage without residue cover can exacerbate which problem?

Which type of mulch is biodegradable and also adds organic matter to the soil as it decomposes?

How does intercropping, particularly with a legume, benefit dryland agriculture?

Consider the following pairs related to dryland agriculture definitions based on rainfall:

1. Dry farming: Annual rainfall < 750 mm, severe moisture stress, crop failure common.
2. Dryland farming: Annual rainfall 750-1150 mm, frequent moisture stress, scope for moisture conservation.
3. Rainfed farming: Annual rainfall > 1150 mm, assured rainfall, no moisture stress.

How many of the above pairs are correctly matched based on conventional definitions?

The practice of planting crops in alternate strips of close-growing crops and row crops, generally perpendicular to the direction of prevailing wind or slope, is known as:

Which of the following is NOT a direct consequence of prolonged drought in dryland agricultural regions?

The selection of appropriate crop varieties for dryland agriculture primarily focuses on which two key traits?

Match the dryland agriculture practice in List I with its primary purpose in List II.

List I (Practice)	List II (Purpose)
1. Zero Tillage	P. To break impermeable layers and improve deep water infiltration.
2. Broad Bed Furrow (BBF)	Q. To reduce soil disturbance and maintain crop residue cover.
3. Deep Plowing	R. To manage excess water during heavy rains and provide better aeration in heavy soils.
4. Windbreaks	S. To reduce wind velocity and minimize wind erosion and evapo-transpiration.
