What is plant husbandry?

I have bo idea

OR

Animal husbandry is the method of taking care of the animal using scientific methods. For example, many farmers do not know how to organize their farm so that the animals are comfortable, and it is possible to rear a large number of them. In animal husbandry there are many techniques of taking care of animals. Grass is cut and then provided to cattle, horses, etc… this is because during grazing the grass is pulled out with its roots. This causes the top soil to loosen and erode; also, it takes longer for the grass to re grow if it is pulled out from its roots.
