who developed a seed drill that planted seeds in straight rows
Seed drill The first known European seed drill was attributed to Camillo Torello and patented by the Venetian Senate in 1566. A seed drill was described in detail by Tadeo Cavalina of Bologna in 1602.[4] In England, the seed drill was further refined by Jethro Tull in 1701 in the Agricultural Revolution. However, seed drills of this and successive types were both expensive and unreliable, as well as fragile. Seed drills would not come into widespread use in Europe until the mid to late 19th century, when manufacturing advances such as machine tools, die forging and metal stamping allowed large scale precision manufacturing of metal parts.

Bow drill Bow drills were used in Mehrgarh between the 4th and 5th millennium BC.[4] This bow drill—used to drill holes into lapis lazuli and carnelian—was made of green jasper.[4] Similar drills were found in other parts of the Indus Valley Civilization and Iran one millennium later.[4]
