Other claims from this paper (11)
- Intervention effect Increasing nitrogen increased maximum tillers and effective panicles.
- Intervention effect B 1 had more maximum tillers and effective panicles than B 2.
- Intervention effect B 3 had more maximum tillers and effective panicles than B 2.
- Intervention effect RGR and CGR were higher with middle nitrogen and early, middle and late fertilizer application.
- Intervention effect NAR was higher under low nitrogen.
- Intervention effect Primary branch number basically did not change with nitrogen amount and distribution.
- Intervention effect Low and middle nitrogen gave almost equal secondary branch differentiation, extant and regressive numbers.
- Intervention effect High nitrogen produced 2 3 more secondary retrogressing branches.
- Intervention effect Nitrogen level and collocation had no effect on spikelets per panicle and 1000 grain weight.
- Recommendation The authors considered 135 165kg/ha nitrogen reasonable under the experiment conditions.
- Recommendation Later growth stage top dressing was considered necessary based on mean yield, depending on nitrogen level.
