Effects of nitrogen application on yield plant characters and nitrogen levels in grain of 6 spring wheat cultivars



Effects of nitrogen application on yield plant characters and nitrogen levels in grain of 6 spring wheat cultivars



Crop Science 16(6): 877-879



A 3 yr study on the effects of rate and time of N application on 6 cultivars of spring wheat (Triticum aestivum L.) indicated that grain yield, plant characters, and N levels in grain can be modified by N application. Maximum grain yield was achieved at 67.5 kg N/ha (67.5 N) or 90 kg N/ha (90 N). The grain yields of 'Selkirk', 'Streng' and 'Kolibri', increased with increasing rates of N from 45 kg N/ha (45 N) to 90 N; while the yields of the high yielding 'Ankra' and 'Opal', were not significantly higher at 90 N than at 67.5 N. 'Reward', the lowest yielding cultivar, failed to respond to increased rates of N as measured by grain yield. Numbers of spikes per square meter increased, but kernels per spike and kernel weight did not increase with increasing rates of N. Photosynthetic area, as measured by spike extrusion, spike area, flag leaf area and kernel N yield, increased significantly at 90 N. Compared to 90 N at seeding, there was no significant benefit in grain yield or related characters including kernel N yield when application of 90 N was split between seeding and stem elongation.
