This review focuses on the mechanisms determining yield in maize, sunflower and soybean,
the three major summer crops of the Argentinean Pampas. Emphasis is given to the capture …

Continued genetic improvement in the ability of hybrid corn (Zea mays L.) to withstand high
plant density stress requires agronomists to periodically reassess optimal plant density and …

Most crop sowing methods result in a highly clumped two-dimensional spatial pattern of
individual crop plants. Ecological theory predicts that increasing the spatial uniformity of crop …

Potential yield benefits from improving within‐row plant spacing variability and plant
emergence variability in corn (Zea mays L.) production are often questioned by growers …

Nonuniform plant spacing within the row in corn (Zea mays L.) may reduce grain yield. To
investigate the response of corn to plant spacing variability, experiments were conducted at …

The literature indicates variable results in response to uneven stands. We tested the
hypothesis that the effect of uneven stands on grain yield varies depending on the …

Planter type, maintenance, and operation play an important role in uniform stand
establishment in corn (Zea mays L.). Research was conducted to determine if planter type …

Improving crop management inputs with remote sensing devices is an emerging technology.
This study documented the progression of the normalized difference vegetative index (NDVI) …

Recent interest in establishing uniform spacing of corn (Zea mays L.) plants in the field has
prompted many seed companies to offer planter‐tuning services. Experiments were …

Seed vigor is defined as those “seed properties that determine the potential for rapid,
uniform emergence and development of seedlings under a wide range of field conditions.” …
