Other claims from this paper (7)

Intervention effect Fertigation raised petiole sap nitrate except early in the season.
Intervention effect Fertigation raised leaf chlorophyll except early in the season.
Intervention effect Plant dry matter was much larger with fertigation.
Intervention effect Total nitrogen accumulation was much larger with fertigation.
Intervention effect Early nitrate leaching was greater with preplant nitrogen.
Intervention effect Later nitrate leaching was greater with fertigation.
Recommendation Authors suggest fertigation at reduced nitrogen rates could sustain adequate nitrogen and equivalent yields while reducing leaching.

Observation Seedling emergence was 44.1 percent in 1994.
Association Seedling emergence increased proportionately with increasing seed rate.
Association Panicle weight decreased at higher seed rates.
Association The number of tillers and panicles increased at higher seed rates.
Association Each increase of 100 panicles m−2 decreased panicle weight by 0.91–1.28 g.
