What is 'salinization' in agricultural soils?
Answer: The accumulation of soluble salts to harmful levels in soil
Salinization occurs when evaporation leaves behind soluble salts that accumulate to concentrations toxic to most crops.
Which practice is used to reduce soil erosion on sloped farmland by plowing across the slope?
Answer: Contour farming
Contour farming involves tilling and planting across the slope rather than up and down, slowing runoff and reducing erosion.
What does 'germination rate' measure in seed quality testing?
Answer: The percentage of seeds that sprout under standard conditions
Germination rate is the percentage of seeds in a sample that successfully sprout under controlled, optimal conditions.
What is the primary function of potassium (K) in crop plants?
Answer: Regulating stomatal opening and improving disease resistance
Potassium regulates stomata to control water use, activates enzymes, and strengthens cell walls, improving overall stress and disease resistance.
Which of the following is an example of a C4 crop plant?
Answer: Corn (maize)
Corn (maize) is a C4 plant, using a more efficient photosynthetic pathway that reduces photorespiration and performs well in hot, sunny conditions.
What term describes the ability of soil to allow water to move downward through its layers?
Answer: Permeability
Soil permeability (or hydraulic conductivity) refers to how easily water can flow through the pores between soil particles.
In agronomy, what is meant by 'yield potential' of a crop variety?
Answer: The maximum yield achievable under ideal growing conditions with no limiting factors
Yield potential is the theoretical maximum output a crop variety can produce when grown without resource limitations such as water, nutrients, or pests.
