Tiller Contributions to Low-Density Corn Biomass and Yield

Effect of leaf orientation and density on yield of corn

Effects on Yield and Plant and Tiller Density in Mixtures of Ryegrass Cultivars

The rycgrass cultivars, Grasslands Manawa and Grasslands Ruanui, were grown in simulated swards in replacement series under systems involving a 2X2 arrangement c.f height and frequency of cutting. Estimates of plant survival at two dates indicate greater overall mortality in the Manawa population. In the earlier part of the experiment the death of Manawa, and of Ruanui plants particularly when ...

Corn grain yield responses to tillage systems and plant densities

Ozone and density affect the response of biomass and seed yield to elevated CO2 in rice

Tropospheric O3 reduces growth and yield of many crop species, whereas CO2 ameliorates the negative effects of O3. Thus, in a combined elevated CO2 and O3 atmosphere, seed yield is at least restored to that of charcoal-filtered (CF) air at ambient CO2. The CO2induced yield increase in CF air is highly variable, suggesting other potential resource limitations. To understand such variability in r...

Responses of soybean yield and yield components to light enrichment and planting density

Light intensity intercepted by the soybean canopy during the reproductive period is an important environmental factor determining soybean yield components and grain yield. A 2-year field experiment was conducted to investigate the effects of light enrichment and its interaction with planting density on yield formation of soybean cultivars. Light enrichment increased seed yield per plant and yie...
