Compare the effects of increasing crop density versus increasing plant spacing on crop yield and resource competition.

Increasing crop density always increases yield without affecting resource competition.

Increasing plant spacing reduces resource competition but may decrease total yield per area.

Increasing crop density reduces resource competition among plants.

Increasing plant spacing always increases yield by improving resource use.

What is the primary purpose of optimizing crop density in agricultural fields?

To ensure maximum light interception and yield

To reduce the need for irrigation

To increase the use of chemical fertilizers

Which of the following best defines the scope of agronomy?

Study of soil formation and classification only

Science of crop production and soil management for sustainable agriculture

Focus on animal husbandry and livestock management

Study of agricultural machinery and equipment

Consider two crops: Crop A has a longer vegetative phase but shorter reproductive phase, while Crop B has a shorter vegetative phase but longer reproductive phase. Which crop is likely to produce high

Crop A, because longer vegetative growth increases biomass and photosynthetic capacity.

Crop B, because longer reproductive phase allows more grain filling time.

Both will produce equal yield as phases balance out.

Yield depends only on soil fertility, not growth phases.

Question 1 of 15

A wheat crop has a leaf area index (LAI) of 3.5 during its peak vegetative growth. If the leaf area per plant is 350 cm² and the plant density is 10 plants/m², calculate the ground area covered by leaves per plant.
