the process of separation the seeds from the crop is called
1 sedimentation
2 threshing
3 evaporation
4 decantation​

Answer 1

Answer:

Threshing is the process of separating the chaff from the grains with the help of blowing air. It is either done by hand or done with the help of a thresher. The chaff from grains is separated from the straw with the help of a thresher. So, the correct option is ' Threshing'.

THRESHING

Answer 2

Hand hammering against an item, treading, or holding the crop against a rotating drum with spikes or rasp bars are all typical methods for manual threshing. For threshing rice that easily shatters, hand beating methods are typically used (i.e., at lower moisture content).

Explanation: Threshing is the process of removing grain from its stalk and the chaff or fluff that surrounds it. The edible portion of the crop loosens throughout the process, but not the fibre portion. It's finished after harvesting and before winnowing. In the past, the process was to manually thrash the harvested grain ears with a thrashing. Instead, the grain was squeezed out of the stalks by goats, donkeys, or bulls. After that, the straw was gathered and raked away after the grains were winnowed to eliminate the debris. During winnowing, the air stream blasted away the light-weighted waste particles, leaving just the hard grain particles.
