Other claims from this paper (9)

Observation Colossal was the largest onion grading size at Carrington in 2003.
Intervention effect Reservoir tillage on beds produced the greatest number of colossal onions.
Intervention effect Fall-formed raised beds tended to give greater onion yield than spring-formed beds.
Intervention effect Fall-formed beds tended to produce more marketable onions.
Observation The planting configuration giving the highest total onion yield varied by place and year.
Intervention effect Reservoir tillage generally increased total onion yield.
Observation Early-season soil moisture and temperature differed little among treatments.
