why is vegetative propagation practiced for growing some vegetables
Yeah, really don't show off.
Especially when you use words that aren't correct. Like fastly. That's not even a word. And check your grammar. I don't know who teaches you English but you're pathetic at it.
If you don't know what pathetic is, let me explain. It means really really bad.
dont show off
vegetative propagation is used in some type of plants because it is a faster method of growing new offsprings. The seedless plants can be reproducted by vegetative propagation. Even if the plants have the seed then also reproduction in that plant can be easily and fastly done by vegetative propagation.
Please don't ask this simple questions . Ask some questions about your level.
