Question

how is seed drill is better than broadcasting

Answer 1

The data indicate that the cultivator and rototiller are preferable implements to incorporate broadcast seed on beds, but that 50% to 100% higher seeding rates for broad casting than drilling are needed. The practical implications for weed and soil management, and planting costs are discussed.

Answer 2

Answer:

Seed drill sows the seeds uniformly at proper distances and depths, whereas broadcasting of seeds scatter them non-uniformly on the ground surface which are susceptible to be picked up by birds.
