Accumulation of excess starch in leaves

Inhibition of root growth

Question 2: What is the impact of excessive irrigation on soil fertility in horticultural crops?

Which action should you take?

Choose only one option

It reduces soil erosion by promoting better root growth

It improves soil structure by enhancing organic matter decomposition

It increases the cation exchange capacity of the soil

It can lead to leaching of essential nutrients

Question 3: How does the application of plant growth regulators (PGRs) affect the growth cycle of a plant?

Which action should you take?

Choose only one option

It prevents root initiation

It can alter the timing of flowering, fruiting, and dormancy
