کرنٹ میٹر کس چیز کی پیمائش کے لیے استعمال ہوتا ہے؟
- Discharge
- Velocity of flow of water
- Depth of flow of water
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- A current meter is an instrument used to measure the velocity of flowing water in rivers, canals, and streams.
- The instrument is placed at selected points in the water, and its readings help determine the flow velocity.
- Water discharge can then be calculated using the measured velocity and the cross-sectional area of the channel.

مٹی کے مساموں میں سطحی تناؤ کی وجہ سے رکا ہوا پانی کیا کہلاتا ہے؟
- Capillary water
- Gravitational water
- Hygroscopic water
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- Capillary water is retained in the small pores of soil by capillary forces arising from surface tension and adhesion.
- It is the main form of soil water available for plant absorption.
- Capillary water can move through soil pores in response to differences in water potential.

- Water held at full saturation
- Water held at permanent wilting point
- Water retained after gravitational water has drained
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- Field capacity is the amount of water remaining in soil after excess gravitational water has drained away.
- At this stage, the soil retains water in its pores, making much of it available for plant roots to absorb.
- Field capacity is an important measure for irrigation scheduling and determining the water-holding capacity of soil.

پودوں کے لیے دستیاب پانی بنیادی طور پر کون سا ہوتا ہے؟
- Gravitational water
- Capillary water
- Hygroscopic water
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- Capillary water is held in the small pores of soil.
- It is the main source of water available for plant absorption.
- It is retained by capillary forces, allowing plant roots to absorb it against gravity.

جب زرعی طلب کم ہوتی ہے تو مجموعی پیداوار پر عموماً کیا اثر پڑتا ہے؟
- Increases
- Decreases
- Remains the same
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- When demand for agricultural products decreases, farmers generally have less incentive to produce the same quantity.
- Lower demand can reduce market prices and farmers’ expected income, leading them to reduce production over time.
- The response is not always immediate because agricultural production also depends on weather, input costs, government policies, and existing stocks.

سخت زمین میں استعمال ہونے والے بڑے دندانے والے زرعی آلات کس سے متعلق ہیں؟
- Subsoiler
- Chisel plough
- Disc harrow
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- A chisel plough is a tillage implement with strong.
- It is widely spaced tines used to loosen hard soil and break compacted layers while leaving much of the soil surface relatively undisturbed.
- Its large, rigid shanks can penetrate firm soil and improve water infiltration and root growth.

درجۂ حرارت بڑھنے سے سطحی تناؤ پر کیا اثر پڑتا ہے؟
- Decreases
- Increases
- First increases then decreases
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- Surface tension decreases as temperature increases.
- Higher temperature increases the kinetic energy of liquid molecules, weakening the effect of intermolecular cohesive forces at the surface.
- Surface tension becomes nearly zero at the critical temperature, where the distinction between liquid and gas disappears.
- Water has a surface tension of approximately 72.8 mN/m at 20°C.

گندم کی لوز سمٹ بیماری کس ذریعے سے پھیلتی ہے؟
- Water
- Seed
- Soil
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- Loose smut of wheat is a seed-borne fungal disease caused by Ustilago tritici.
- The fungus infects the developing wheat embryo, and the infected seed may appear healthy externally.
- When infected seeds germinate, the fungus grows with the plant and eventually replaces the grain in the ear with black, powdery spores.

زرعی جنگلات پر مبنی صنعت کون سی ہے؟
- Textile
- Furniture
- Construction
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- Agroforestry is a land-use system that combines trees or shrubs with agricultural crops and/or livestock.
- The furniture industry uses wood obtained from trees grown in forests and agroforestry systems.
- Trees grown on farms can provide timber, reduce pressure on natural forests, and generate additional income for farmers.

ڈینیٹریفیکیشن کس قسم کا عمل ہے؟
- Hydrolysis
- Oxidation
- Reduction
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- Denitrification is a biological reduction process in which microorganisms convert nitrate into gaseous nitrogen compounds, mainly nitrogen gas.
- It usually occurs under anaerobic conditions, when oxygen is limited in the soil.
- This process returns nitrogen to the atmosphere and reduces the amount of nitrogen available to plants.
