Impact of N Supply on Some Leaf Characteristics of Maize Crop

Nitrogen (N) is an essential nutrient widely used in maize crop production. The application of a high N rate commonly practiced by growers as "guarantee" optimal growth and yield. However, excessive nitrogen consumption can cause wastage, negatively impact plants, adversely affects the environment. This paper reports on supply leaf characteristics maize. Maize was grown experimental plot Department Agronomy, Hungarian University Agriculture Life Sciences, Hungary, during spring summer 2021 (May - October). Four observation plots consisting ​​102 m area size were evaluated for various levels (0, 50, 100, 150 kg ha-1 a.i) with marked plants sampling four replications. Data collection traits viz. number plant-1 (B), (S), temperature 0C (leaf surface), SPAD, length (cm), width (cm2) measured one week after weekly sequences until eighth week. results showed that fertilizer increased temperature, while contrasting (S). there no difference all treatments studied. Although increase occurred up to use 100 N. Whereas, treatment low performance exhibited negative correlation except leaves suggest produced best most Furthermore, detailed research study needed confirm findings, many other environmental factors influence plant growth.
