Question

Which of the following should be used by a farmer with a large farm to harvest his crops quickly and efficiently.
a) winnowing
b) sickle
c) combine
d) seed drill ​

Answer 1

Answer:

combine.

because it reduces the labour cost very much and do the same work in very less time

Answer 2

The farmer should use the technique of combination to harvest crops quickly and efficiently.

• Harvesting is the cutting of the abundant crop close to the fertile ground after it is ripe. Employing specific instruments like a sickle, farmers with small farms gather their crops manually.  
• Nevertheless, they need to manually perform threshing and winnowing after harvesting.  
• Whereas, as it is more time consuming, farmers with extensive farms can not deploy manual labour for harvesting and threshing.
• Instead, using equipment such as a mixer is more effective for them. An ideal mixture efficiently carries out both the harvester and the thresher role. It saves both time and labour.
