Effects of different fertilizer combinations on the yield and nitrogen use efficiency of summer maize in Jiangsu Province, China.

ABSTRACT: The rational application of nitrogen (N) fertilizer plays a crucial role in promoting crop growth and increasing yields. The application of slow-release fertilizer has emerged as an important agronomic measure to further increase yield and production efficiency. In this study, a field trial with the maize hybrid Jiangyu877 was conducted to investigate the effects of six fertilizer combinations [no fertilizer (P1), common N application (P2), slow-release N application (P3), common N and slow-release N 1:1 application (P4), 1:2 application (P5), and 2:1 application (P6)] on yield and nitrogen use efficiency (NUE). Fertilization significantly increased maize yield, with the greatest increase occurring in the treatment combining common and slow-release N. Among all the treatments receiving equ
