All the voltammograms show rectangular curves, which are typical characteristics of capacitors. The calculated average electric-double layer capacities in this potential range are 0.15 mAh g −1 for HC-Mg, 0.12 mAh g −1 for HC-Zn, and 0.97 mAh g −1 for HC-Ca (corresponding to 0.90, 0.72, and 5.8 F g −1, respectively).
Additionally, the duration of the filling peak, active filling period, and maximum and average filling rate were decreased ; the grain plumpness was insufficient; and the grain weight was significantly reduced . In summary, shading stress reduced the photosynthesis of maize, resulting in a lack of energy and material supply in a series of ...

Introduction. Nitrogen (N) is a major nutrient for maize (Zea mays L.) production and also takes part in the plant physiological process as a significant component, such as enzymes, hormones, and amino acids (Thind et al., 2011; Ciampitti and Vyn, 2012).Therefore, to get a higher yield, high N application is the most common practice for …
