a-vi Mixed cropping is practice of growing two or more types of crops simultaneously on the same piece of land. b-v Crop rotation is the growing of different crops on a piece of land in a pre-planned succession. Consider a farmer who has planted a cornfield. He might plant beans after the corn harvest is ended because maize consumes a lot of nitrogen while beans restore the same to the land. c-ii 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. d-iii Sahiwal is a breed of Zebu cattle which primarily is used in dairy production. e-iv The Aseel is a breed of chicken originating from Indian subcontinent. f-i Pisciculture is the rearing of fish for food in enclosures such as ponds or tanks. g-vii Inter-cropping is growing of two or more crops simultaneously in the same field in definite row pattern. h-xi Congress grass is one of the weed which is commonly known as carrot grass. i-viii Linseed is rich in fat which is made of glycerol and fatty acid. j-ix Apiculture is the technical term for beekeeping.

a-iii A working animal or draught (or draft) animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks. b-v The Asil or Aseel is a breed of chicken originating from Indian subcontinent. It is famous in Indian states of Andhra Pradesh and Tamil Nadu. c-iv Sahiwal is a breed of Zebu cattle which primarily is used in dairy production. d-i Milch animals are those animals who give milk. e.g. Cow, Buffalo, etc. e-ii A broiler is a chicken species ( Gallus gallus domesticus ) that is bred and raised specifically for meat production. Broilers are given high protein feed.

Match the following. Column I Column II (a) Catla (i) Bottom feeders (b) Rohu (ii) Surface feeders (c) Mrigal (iii) Middle-zone feeder (d) Fish farming (iv) Culture fishery

(a) - (ii) Catla and silver carp are surface feeders. These are freshwater fishes. (b) - (iii) Rohu feed in the middle-zone of the pond, i.e., column feeder. (c) - (i) Mrigal carps are bottom feeders. (d) - (iv) Culture fishery is one of the ways of obtaining fishes. In this, fishes are obtained from fish farming. A culture fishery is a sort of inland fishery that takes place in tiny bodies of water and involves the rearing and harvesting of desired species. In culture fishery, all indigenous fishes are herbivores.
