HAND OPERATED SEED BROADCASTING DEVICE

• The main disadvantage of broadcasting by hand is the non-uniformity of distribution. This causes uneven crop growth which results in poor yield.
• The hand operated broadcasting device consists of a plastic hopper with agitator, a rotating disc made of aluminium sheet with projections and a handle. By rotating the handle the disc is made to rotate at a speed of 500 rev/min.
• The hand operated broadcasting device spreads the seeds 50 per cent more uniformity with respect to hand broadcasting. The device is hung infront of the operator. The material is spread, over a width of 3.5 to 10 metre. The unit weighs only 3.6 kg and costs about Rs.1500/-.
• The seed rate can be varied by changing the opening area at the hopper bottom. The device is capable of covering one hectare per hour.
