Other claims from this paper (8)

Association Germination onset follows a thermal-time relationship at 5–20°C.
Intervention effect 15°C hydration was most effective for Tall Utah 52–70 when seeds were surface-dried.
Intervention effect 15°C hydration was most effective for Green Giant Hybrid when seeds were surface-dried.
Intervention effect Air-drying treated seeds at 20°C severely delayed germination.
Intervention effect Air-drying treated seeds at 20°C decreased germination uniformity.
Mechanism Thermodormancy limited germination benefit at higher temperatures, especially 25°C.
Intervention effect Slowing drying through controlled humidity avoided drying-back damage.
Intervention effect Slower drying sometimes enhanced germination further.

Other claims from this paper (3)

Intervention effect Hydrogels produced little to no difference in leaf expansion rate.
Intervention effect Hydrogels enhanced root growth early in production.
Intervention effect Plants grown in hydrogels needed irrigation less often than those without hydrogel, with the difference diminishing over time.

Field trials with the controlled drop application of barban and difenzoquat for the control of wild oats (Avena fatua L.) in spring barley

B. J. WILSON; W. A. TAYLOR Weed Research 1978. doi:10.1111/j.1365-3180.1978.tb01611.x

Other claims from this paper (8)

Intervention effect At 45 l/ha, difenzoquat control of Avena fatua in barley was equal or superior to conventional application.
Intervention effect At 15 l/ha, difenzoquat control of Avena fatua differed little from conventional application.
Intervention effect At 45 l/ha, controlled-drop barban gave slightly poorer wild oat control than conventional application.
Intervention effect At 15 l/ha, controlled-drop barban gave slightly poorer wild oat control than conventional application.
Intervention effect Oil solutions for controlled-drop barban caused slight barley injury.
Intervention effect Wild oat control with both herbicides at 5 l/ha was inferior.
Intervention effect Wild oat control with barban at 10 l/ha in 1974 was inferior.
Recommendation The authors suggest a 15 to 45 l/ha optimum volume for controlled-drop application of these herbicides.

Performance of spring cereal genotypes under defoliation on the Eyre Peninsula, South Australia

R. A. Latta Crop and Pasture Science 2015. doi:10.1071/cp14026

Other claims from this paper (6)

Observation Barley varieties produced up to twice the dry matter of wheat or oats cultivars before defoliation.
Intervention effect Mowing after stem elongation more than halved early maturing grain yield relative to no defoliation.
Intervention effect Later maturing varieties had less grain yield loss from mowing after stem elongation.
Intervention effect Long-season winter wheat grain yield was similar across defoliation timings.
Observation Winter wheat had no yield advantage over defoliated spring cereals.
Recommendation The authors suggest grazing cereals for winter feed in the low rainfall zone.
