Question

Rahim removed weeds in this crop field, but David did not. Guess who get more yield and why?

Answer 1

Rahim will get more yield. Weeds are undesirable plants which grow in an agricultural area. They compete with the crop for water and soil nutrients. Some weeds produce toxic substances which damage neighboring crops. They also provide shelter for insects that may decrease crop yield. Hence it is necessary to remove weeds before cropping.
