Title

Studies in crop variation. I. An examination of the yield of dressed grain from Broadbalk

R. A. Fisher The Journal of Agricultural Science 1921. doi:10.1017/s0021859600003750

Other claims from this paper (8)

Observation Plots 2 b and 8 had slower yield decrements than plot 7.
Intervention effect Potassium sulphate and substitutes influenced wheat yield.
Observation All plots underwent similar slow changes in mean yield.
Method / resource Three types of variation were distinguished.
Method / resource Long series of average wheat yields from different fields or seasons cannot match same-field same-season plot comparisons in accuracy.
Method / resource Slow changes in mean yield make even long series of different years from one field inaccurate to compare.
Observation Changes in mean yield sensibly affect average comparisons for plots 17 and 18.
Recommendation The authors advise comparing plots 17 and 18 with other plots during high yielding periods.

Other claims from this paper (10)

Association Harvest speed varied with crop maturity and weather.
Association Earlier-season ginning amounts depended principally on maturity timing.
Association Later-season harvest speed was determined by prevailing weather.
Observation On November 1, an average 37 per cent of the matured cotton crop remained to be ginned.
Observation An average 57 per cent of the cotton remaining unginned on November 1 was ginned during November.
Association November weather produced substantial year-to-year variation in the November ginned percentage.
Association Rainy and cloudy days had a close negative association with the November ginned percentage, with correlation −0.91 ±0.03.

Other claims from this paper (13)

Association The viable planting period generally decreases with increasing latitude.
Observation Most staple spring planted crops need very similar accumulated heat to mature when average corn variety is considered.
Recommendation The authors recommend crop-specific planting temperature as the base for temperature summation.
Observation Spring wheat seeding begins at a lower mean temperature than other major spring crops.
Observation Spring wheat seeding begins at 37°F in the Dakotas and Nebraska.
Observation Spring oats seeding begins at a normal daily temperature of −13°F.
Observation Early potato planting generally begins at 45°F.
Observation Corn planting begins at 55°F.
Observation Cotton planting generally begins at about 62°F.
Observation The available thermal constant for corn is about 1,600°F.
Observation The available thermal constant for cotton is about 2,000°F.
Association Lowering cotton planting temperature to the corn threshold would materially enlarge the cotton production area.
Observation Corn and cotton need a comparatively warm spring for best germination and early growth.
