Describe the mechanical method of protecting crop from birds. |

Answer» 1. Making explosions: Make false gun shots at different time intervals to scare the birds. 2. Using scarecrow: Take a small pitcher, draw human face on it using colour. This pitcher is made to hang on the sticks fixed vertically in the fields. Put on human clothes on this structure. This is known as scarecrow. Birds consider this structure as human being and do not come to the field. 3. Hanging dead crows: Parrot has little communal association with crows. Therefore, to keep the parrots away from the fields, hang 1-2 dead crows/their dumies at sites of frequent bird damage. This way we protect oilseed crops from parrots. 4. Using rope-crackers: Tie fire crackers on a rope at 6-8 inch distance. Ignite the lower end of the rope. Explosions caused by fire crackers at different intervals scare the birds and the birds fly away. Fix the rope in the center at the time of germination and at the boundaries of the field at the time of maturity. |
