Laboratory and field trials were conducted to determine the extent of the genetic variation among 134 Russian wild ryegrass (Elymus junceus Fisch.) progeny lines for characters related to stand establishment under semiarid conditions. Progenies were evaluated in the laboratory for seedling emergence and subsequent vigor using a 7.6-cm planting depth, seedling emergence under controlled soil moisture stress, and seedling recovery after exposure to drought. Significant genetic variation was detected for emergence, seedling vigor, and stand establishment in the field and for all measurements made in the laboratory except seedling recovery after drought. The genetic variance comprised from 50 to 60% of the total phenotypic variance in most instances. Emergence and subsequent seedling vigor from a 7.6 cm planting depth were the most closely related to data collected in the field (r = 0.17–0.33**). Results from the other laboratory trials were not significantly correlated with field performance.

The objective of this study was to ascertain if stand establishment of sh2 sweet corn (Zea mays L.) would benefit from variable planting depths determined by the use of geographic information systems (GIS). Spring and fall research plots were established in a field [80 × 20 m (262 × 66 ft)] containing Crosby silt loam and Kokomo silty clay loam soil series in Columbus, Ohio. Three sh2 sweet corn cultivars (Starship, Skyline, and Confection) were planted at three depths on the two soil types in the fall study, with an additional transition soil added in the spring. Emergence counts as well as soil moisture and temperature were monitored. In the spring, sites were also sampled for nutrient levels and soil compaction. Significant variability was found within the field with respect to soil moisture, temperature, nutrient levels, and compaction. Seedling emergence fluctuated with average soil moisture increasing in blocks with up to 24% moisture and then leveling off. Daily minimum soil temperatures impacted stand establishment. Although heat units accumulated faster on the Crosby soil, emergence was slower and less complete on these soil series than on Kokomo soil series. Further investigation determined that although temperatures of the Crosby soil were 3 to 4.5 °C (5.4 to 8.1 °F) warmer during the day than the Kokomo soil, temperatures on the Crosby soil averaged 2 °C (3.6 °F) cooler at night. Analysis of emergence patterns and field variability was performed on ArcView mapping software. Although `Skyline' planted at 2 cm (0.8 inches) had the best emergence overall, final stand would have been increased with `Skyline' planted variably at 2 and 4 cm (1.6 inches). Mapping the field under these different scenarios showed that although area with less than 70% stand would exist with a 2-cm uniform planting depth, the entire field would have a stand of 70% or greater with variable planting depth using a high vigor seedlot.
