Description:
Experiments with various cultural and fertilizer treatments on stubble land were conducted at five locations on the prairies from 1955 to 1961 to determine their effect on yields of wheat.Significant yield differences between treatments ranged from 4 to 8 bu of wheat per acre at all stations. At Lacombe, Alta., Melfort and Regina, Sask., the highest average yields were obtained from fall or spring burning of the crop residue followed by normal spring operations. At Lacombe and Melfort, alternative methods gave results which were not significantly different from the burn treatments. These included fall plowing or disking at Lacombe and fall cultivating at Melfort. At Indian Head, Sask., plots which were not tilled in the fall but disked the following spring yielded 5 bu per acre more than those that were fall plowed and 2 bu per acre more than those where burning and tillage was employed. The yields from plots at Melita, Man., which were plowed or one-way disked in the fall produced 7 bu per acre more than those which were not fall tilled and only disked prior to seeding.Fertilizer increased yields of wheat significantly at all stations. Nitrogen at 50 lb with phosphate at 20 lb per acre produced the greatest 5-year average yield at Lacombe and Indian Head. At Melfort, Regina, and Melita, similar returns were obtained with applications of 16 to 50 lb of nitrogen plus 20 lb of phosphate per acre.
