- A. 20004000 ft
- B. 0008000 ft
- C. 1200014000 ft
- D. 02000 ft
Explanation: Field crops are generally grown in the lower-altitude plains, commonly from sea level up to about 2,000 feet.
Correct answer: 02000 ft- A. Water stress
- B. Wilting
- C. Drought
- D. None of the above
Explanation: Wilting is the visible drooping or drying of plant parts when water loss exceeds water absorption and cell turgor falls.
Correct answer: Wilting- A. Pyrethrum
- B. Cocon
- C. Co see
- D. Tobacco
Explanation: Tobacco is a major narcotic or stimulant crop cultivated in Pakistan, especially for cigarette and other tobacco products.
Correct answer: Tobacco- A. Monocropping
- B. Single cropping
- C. Double, cropping
- D. All the above
Explanation: Monocropping means growing the same crop repeatedly on the same land, often year after year.
Correct answer: Monocropping- A. 30%
- B. 21%
- C. 16%
- D. 45%
Explanation: Oxygen makes up about 21% of atmospheric air by volume, while nitrogen is the dominant gas at about 78%.
Correct answer: 21%- A. 70% nitrogen
- B. 78% nitrogen
- C. 50% nitrogen
- D. None of the above
Explanation: Nitrogen constitutes approximately 78% of atmospheric air by volume, making it the most abundant atmospheric gas.
Correct answer: 78% nitrogen- A. Higher shoot weight
- B. None of the above
- C. Higher root weight
- D. Lower shoot weight
Explanation: Weak or low-vigour seeds have poorer membrane integrity, so they release more electrolytes into the soaking solution and show higher…
Correct answer: Lower shoot weight368. Use of linear measurements of plumule growth as a vigour test was first suggested by_______________?
- A. Germ (1949)
- B. Woodstock (1976)
- C. Baskin (1972)
- D. Maguire (1962)
Explanation: Germ (1949) was associated with using plumule or seedling growth measurements to assess seed vigour.
Correct answer: Germ (1949)- A. Quantity of seeds
- B. Quality of seeds
- C. Seed density
- D. All the above
Explanation: Quality seed improves establishment, uniformity, crop stand and yield potential, whereas simply increasing seed quantity or density can…
Correct answer: Quality of seeds- A. IID grains
- B. Both a & b
- C. LD grains
- D. None of the above
Explanation: Low-density rice grains are commonly less mature or poorly filled, so they have lower vigour and are more associated with abnormal…
Correct answer: LD grains- A. Al the above
- B. Lack of integrity in seed cells
- C. Endogenous inhibitors
- D. Intrinsic Mechanism
Explanation: Abnormal seedling growth can result from internal developmental mechanisms, loss of cellular integrity, or endogenous growth-inhibiting…
Correct answer: Al the above- A. 45°c for 3-8 days
- B. 50°c for 3-7 days
- C. 54°c for 2-6 days
- D. None of the aboveSearch Public Records
Explanation: Rice seed dormancy can be reduced by dry-heat treatment at about 50°C for several days, commonly 3 to 7 days.
Correct answer: 50°c for 3-7 days- A. Foundation seed
- B. Certified seed
- C. Breeder seed
- D. Registered seed
Explanation: Nucleus seed is the genetically pure starting stock maintained by the breeder, and its multiplication produces breeder seed.
Correct answer: Breeder seed- A. Germ (1949)Order Crop Seeds
- B. Baskin (1972)
- C. Moore (1973)
- D. Maguire (1962)
Explanation: Maguire’s formula estimates germination speed by summing the number germinated at each count divided by the days elapsed.
Correct answer: Maguire (1962)375. Who the a method of estimating seed vigour on the basis of color intensity of the stained seeds ?
- A. Nicolls & Hey Decker (1968)
- B. Kittock &. Law (1953)
- C. Moore (1973)
- D. Germ (1949)
Explanation: Kittock and Law are credited in seed-testing references with estimating vigour from the intensity of colour developed in stained seeds.
Correct answer: Kittock &. Law (1953)376. The total dry matter produced by a plant as a resulting photosynthesis is called_______________?
- A. Physical productivity
- B. Mass
- C. Biological yield
- D. None of the aboveOrder DNA Kits
Explanation: Biological yield is the total dry matter accumulated by a plant, including grain and vegetative parts, as a result of photosynthesis.
Correct answer: Biological yield- A. None of the above
- B. Range
- C. Resin
- D. Pioneer
Explanation: A pioneer is the first plant or vegetation type to colonize and occupy a newly exposed or disturbed area.
Correct answer: Pioneer- A. 30°C
- B. 40°C
- C. 50°C
- D. None of the above
Explanation: A hot desert is typically characterized by a very high mean annual temperature, conventionally represented in basic agronomy texts as…
Correct answer: 30°C- A. Litter
- B. Foraging
- C. Lopping
- D. None of the above
Explanation: Lopping means cutting or removing branches, commonly from trees or shrubs, to obtain fodder or forage.
Correct answer: Lopping- A. Dry condition
- B. None of the above
- C. Desert area
- D. Moist places
Explanation: Mesophytes are plants adapted to moderate water availability, so they grow best in moist but not waterlogged places.
Correct answer: Moist places
