Table 1.  Analysis of variance of contrasting seeding rates and hard red spring cultivars across conventional-, reduced-, and no-tillage environments in a wheat-fallow rotation experiment located at Dickinson, ND, during 1995, 1996, and 1997.

Table 2.  Plant height, grain yield, kernel weight and crude protein concentration of five semidwarf and five conventional-height hard red spring wheat cultivars across wheat-corn, wheat-black fallow, and wheat-wheat rotations during 1994, 1995, 1996, and 1997.

Figure 1.  Grain yield of five hard red spring wheat cultivars at three seeding rates across conventional-, reduced-, and no-tillage environments in 1996 at Dickinson, North Dakota.  Differences in yield were detected between the 500 000 and 1 000 000 PLS/acre seeding rates for the cultivar Bergen at the P <0.05 level of significance.

Figure 2.  Grain yield of hard red spring wheat following wheat, corn, and fallow during 1994, 1995, 1996, and 1997 at Dickinson, North Dakota.  Differences in yield were not detected at the P <0.05 level of significance.

Figure 3.  Grain yield of two hard red spring wheat cultivars after wheat, corn, and fallow during 1994 at Dickinson, North Dakota. Differences in yield were not detected at the P<0.05 level of significance.

Figure 4.  Grain yield of two hard red spring wheat cultivars after wheat, corn, and fallow during 1995 at Dickinson, North Dakota.  Differences in yield were not detected at the P<0.05 level of significance.
