Agriculture, 2023 Weeds impose serious problems in maize (corn) production, resulting in reduced crop yields and lower profits for farmers. The adverse effects of weeds have been attributed to the competition with maize plants for light, water, and nutrients, which can ...

Application and Interpretation of Deep Learning for Identifying Pre-emergence Magnetic Field Patterns [PDF]
Astrophysical Journal, 2020 Magnetic flux generated within the solar interior emerges to the surface, forming active regions (ARs) and sunspots. Flux emergence may trigger explosive events—such as flares and coronal mass ejections, and therefore understanding emergence is useful ...

Pre-Emergence Rotting of Peas in South Australia [PDF]
Australian Journal of Biological Sciences, 1964 Laboratory tests have shown that individual wrinkle-seeded pea seeds vary in their ability to continue vigorous growth after germination. After the radicle has broken through the testa, SOme produce normal seedlings, some fail to develop further, while others afe intermediate between these extremes and produce stunted seedlings. Thus some seeds capable

Chemical Control of Morning Glory Species in Sugarcane Harvested in the Dry and Semi-Wet Seasons1 [PDF]
Planta Daninha, 2016 The control of morning glory (Ipomoea spp. and Merremia aegyptia) was evaluated in five commercial sugarcane-production fields receiving applications of the herbicides sulfentrazone (0.9 kg ha-1), amicarbazone (1.4 kg ha-1), imazapic (0.147 kg ha-1), and

HELIOSEISMOLOGY OF PRE-EMERGING ACTIVE REGIONS. III. STATISTICAL ANALYSIS [PDF]
The Astrophysical Journal, 2014 The subsurface properties of active regions prior to their appearance at the solar surface may shed light on the process of active region formation. Helioseismic holography has been applied to samples taken from two populations of regions on the Sun (pre-emergence and without emergence), each sample having over 100 members, that were selected to ...
