Reducing Corn Yield Variability and Enhancing Yield Increases Through the Use of Corn-Specific Growth Models
… plants m-2); subplots were hybrids of differing relative maturity (RM) [early = Pioneer® Brand "34B97" (108 day RM); medium = Pioneer® Brand "33M54" (114 day RM); and late = Pioneer® Brand "31G66" (118 day RM)]. Model validation was generated from large scale, replicated strip plot trials …

Genetic improvement for nitrogen utilization in maize
… N utilization as the ratio of total biomass relative to total plant N, which effectively controls for the significant impacts of N-level, relative maturity, and heterosis on this trait. Using this measure of total N utilization, we identified the allelic genotypes associated with enhanced N …

Measurements and modelling of eutrophication processes in Lake Rotoiti, New Zealand
… variations in nutrient concentration showed relatively low correlation coefficient values, in particular at a station located in a shallow embayment. An examination of the behaviour of a conservative tracer introduced into the major inflow of Lake Rotoiti, the Ohau Channel, confirmed previous …

The study and learning strategies of students in a New Zealand tertiary institution
… difference in the two populations was due to the relative maturity of the cross-sectional population or to a change in the college programme which was instituted between the two phases could not be determined. It is probable that both these actors were involved. Interviews with students revealed …

Genomic improvement of nitrogen utilization efficiency in maize
… parents effectively controls for the impacts of relative maturity and heterosis on this trait. The results of this research indicate that available soil N in this geographical region is typically sufficient for inbreds to reach sink capacity, thereby limiting nitrogen response to supplemental N …

Innovations in fertilizer use and agronomic management for greater productivity of corn and soybean
… (corn only), plant population (corn only), relative maturity (soybean only), seed treatment (soybean only) and row spacing. Individual agronomic factors such as narrower row spacing or P and K fertilizer applications resulted in the largest yield increases of all management practices; …
