View larger version (48K): [in a new window]   Fig. 1. Climatic conditions from April to August during 1999 to 2001 at Swift Current. Daily maximum and minimum temperature (°C) and rainfall (mm) are presented with solid line, dashed line, and solid bars, respectively. Open arrows on the horizontal axis indicates early spring seeding date, while solid arrow for 2001 indicates late spring seeding date.

Arrow and plant population in field trials during 1999 to 2001 early spring (ES) and 2001 late spring (LS) at Swift Current. The dotted line is the mean seed yield of 4 yr normalized to 80 plants m-2.

Effect of uniformly distributed plant population and environment on the number of pods produced on main shoot, primary branches, and secondary branches in canola cv. Arrow during 2000 (solid triangle) and 2001 early spring (open triangle) at Swift Current.

Arrow at different uniform plant populations in 2000 at Swift Current. Whenever the differences among plant populations were significant (P ≤ 0.05) for a yield component at a particular node, LSD values are presented as horizontal bars. For the sake of clarity, data from 40 and 10 plants m-2 are not presented.

Arrow at different uniform plant populations in 2001 (early spring) at Swift Current. Whenever the differences among plant populations were significant (P ≤ 0.05) for a yield component at a particular node, LSD values are presented as horizontal bars. For the sake of clarity, data from 40 and 10 plants m-2 are not presented.
