What are the difference between multiple cropping and modern cropping?

Modern Farming:

Modern farming implies the use of modern agricultural inputs to the production of a particular crop. Different crops are grown during a different period of the year. Farmers can grow different crops in a year with the help of a well-developed irrigation system. Chemical fertilizers, HYV seeds, farm machinery and artificial irrigation are used.

Multiple cropping:

Two or more crops are grown at a same period or season in same piece of land. It is a type of poly-culture. Example: growing tomato + onion + marigold during same season and same land. Also, marigold repels some tomato pests. Different crops require different nutrients, hence the land is better utilized. It also helps to maintain soil's fertility. It does not give space for weds and hamper to grow.
