Corn growth and development responds to temperature and is not controlled by day length. Thus, the calendar date is not as important as soil and air temperature when considering optimum timing to plant corn. Good germination and emergence are expected when the soil temperature at a 2-inch depth...
The N applied by pre-planting and side-dressing at the critical growth stages can increase the corn yield38,39. In this study and similar to some of the other researchers' split application, N fertilizer was applied twice (at jointing stage and heading stage), as in the typical N ...
However, large composite time intervals may smooth critical crop growth stages over, thus making the 16-day composites imperfect for yield forecasting (Labus et al., 2002). Previous studies have shown different impacts of composite time interval on crop yield forecast. Johnson et al. (2016) ...

These results suggest that PPO, a fundamental enzyme involved in defense response in mature plants, is inactive at the early plant growth stages. Moreover, the PPO expression may be induced by specific factors such as exposure to certain pathogens (Gul et al., 2016; Hedin et al., 1984). ...

agree that counting leaf collars is the most consistent and accurate means of determining corn leaf stages. The collar is a visible, light colored band at the base of the leaf blade, separating the blade from the leaf sheath 3 . Leaf stages are designated using a “V” (vegetative) to ...
