Answer 1

A) Mari-culture:  Mariculture is a specialized branch of aquaculture involving the cultivation of marine organisms for food and other products in the open ocean, an enclosed section of the ocean, or in tanks, ponds or raceways which are filled with seawater.

B) Mixed cropping: Mixed cropping, also known as inter-cropping or co-cultivation, is a type of agriculture that involves planting two or more of plants simultaneously in the same field. In general, the theory is that planting multiple crops at once will allow the crops to work together.

C) Weed management: It is the process of keeping or minimizing the weed population and their growth below the level of economic injury to the crop with minimum environment pollution.
Weeds can be managed by adopting any suitable method of weed control and if needed by combining two or more methods of weed control.
