Question

Which of the following should be used by a farmers with a large farm to harvest his crop quickly and affectionately

Answer 1

Answer:

(a) Combine

Explanation:

• "Harvesting" is the 'cutting of the crop" "close to the ground"  once it matures. Small farmers usually harvest their crops "manually" using tools such as a sickle. But, after harvesting, they have to manually undertake winnowing & threshing. Likewise, farmers with big farms cannot employ manual labour for threshing & harvesting, since it is very time consuming.

• Rather, it is more effective for them to utilise machines like a combine or a combine harvester. A combine harvester does the function of both harvester & thresher. Amongst the crops that are harvested with a combine harvester are oats, wheat, barley, rye, maize, corn, soybeans, sorghum, flax (linseed), canola, & sunflowers. A combine harvester is one of the most "economically essential labor saving inventions, considerably "reducing the fraction" of the people needed in agriculture.
