A Study in Sampling Technique with Wheat.

R. J. Kalamkar The Journal of Agricultural Science 1932. doi:10.1017/s0021859600054599

Other claims from this paper (7)

Observation Edge rows yielded significantly more than inside rows.
Method / resource Subdividing the sampled area gave a slight advantage without more labor.
Method / resource Four parallel half metre lengths on adjacent rows appeared the most precise sampling unit.
Association Half metre segments in those units appeared negatively correlated.
Method / resource Those sampling units had significantly lower sampling error.
Recommendation The authors advise against using edge rows in yield trials.
Recommendation The authors recommend the four parallel half metre unit for sampling.
