Answer:- (Ancient) 1️⃣BROADCASTING= The traditional tool comprises of a funnel connected to 2-3 tubes that have sharp ends.Seeds put into the funnel travel into the tubes whose sharp ends penetrate into the soil and place seeds at proper depths.
2️⃣IRRIGATION= Traditional irrigation involves drawing water from wells,lakes, and canals by using cattle or human labour. The lifted water is then taken to the fields for irrigation.
(Modern):- 1️⃣BROADCASTING=Seed drill- The mechanism involved in seed drill is very similar to a traditional tool, but the efficiency is higher. The seed drill is connected to a tractor and has many tubes leading to the plough. This method saves time and labor and is more efficient than a traditional tool.
2️⃣IRRIGATION= SPRINKLER SYSTEM:- This system is used in places where the land is uneven or the soil is sandy. The sprinkler system involves a network of vertical pipes that have rotating nozzles on top. The pipes are joined to the main pipeline at regular intervals. When the main pipe is turned on, pressurized water flows out through the rotating nozzles. The nozzle sprinkle water on crops evenly.
