Question

Maximum yield of maize is abtained with a population of 4oooo plants per hactare. The rows are 100 cm apart and an average emergence is 90 % expected. What would be seed spacing?

Answer 1

Explanation:

Area = No. of plant X Spacing (Row to Row distance X Plant to Plant distance)

So here,

10000 = 32000 X 0.91m X Plant to Plant distance

or, Plant to Plant distance = 10000/(32000 X 0.91)

or. Plant to Plant distance = 0.343m
