Solution(By Examveda Team)

1. Topping is a process by which the aerial part of a crop is removed to avoid seed formation and distribution onto the soil. It makes the plant more bushy and stout. E.g. gram.

2. Peg, an unusual stalklike structure grows from the base of the flower toward the soil formed after pollination and the withering of the flower. And this phenomenon called geocarpy is the peculiar characteristic of groundnut.

3. Ratooning is an ancient method of propagation in sugarcane in which subterranean buds on the stubble give rise to a new crop stand.

4. Staking is the phenomenon to tie tomatoes to an upward rod-like structure that encourages growth.
