ABSTRACT
Nitrogen is an essential element for maize growth. The crude protein produced by maize is related to the amount of nitrogen within the tissue. Different amounts of nitrogen could generate different amounts of crude proteins in maize plants. This study focuses on the determination of the crude protein production from different amounts of nitrogen composition in the fertilizers. A total of sixty maize seeds (GWG 888) were planted at Universiti Sultan Zainal Abidin (UniSZA) Kampus Besut Farm. Four different fertilizer treatments were used for the plant species, including control, NovaTec, foliar, and urea. The data for morphological and physiological characteristics, including plant height, the distance of nodes, leaf width, and leaf length, were taken every two weeks. The physiological parameters, including chlorophyll content and stomatal conductance, were recorded during plant growth. The results showed that there is an increase in crude protein content from the difference in nitrogen fertilizer treatment compared to control. The NovaTec fertilizer treatment produces the highest crude protein in the kernel and leaf in maize, followed by urea and foliar. It can be concluded that a higher amount of nitrogen can induce higher production of crude protein in maize.
