Final answer:
Jethro Tull, an English agricultural innovator, promoted the seed-drill in the 18th century, which greatly improved seed germination and farming efficiency.
Step-by-step explanation:
The person who promoted the seed-drill in the 18th century was Jethro Tull. Tull was an English agricultural pioneer from Berkshire who perfected the horse-drawn seed drill in 1701. This invention sowed seeds in neat rows and at a specific depth, which significantly improved the germination of seeds and the efficiency of farming. Jethro Tull's seed drill is often cited as a key development in the Agricultural Revolution, which greatly enhanced crop productivity and paved the way for more advanced agricultural practices. Although the technological advancements and entrepreneurs of the 19th century, such as Eli Whitney and Cyrus McCormick, are often remembered for devices like the cotton gin and the reaper, it was Tull's seed drill that helped transform farming methods a century earlier.
