Maize yield increased by 10.9% at the high fertilization level compared to that at the low fertilization level. The maize yield was 10.2% higher in the treatment with one drip line per two rows than that in the treatment with one drip line per row. ![]() The results showed that maize yield was significantly affected by both dripline spacing and fertilization rate. Two dripline spacings (i.e., one drip line per row of maize with a row space of 60 cm and one drip line per two rows of maize) and two fertilization rates (i.e., high fertilization level: N, 180 kg ha −1 P 2O 5, 90 kg ha −1 and K 2O, 90 kg ha −1 and low level: N, 139.5 kg ha −1 P 2O 5, 76.5 kg ha −1 and K 2O, 76.5 kg ha −1) were employed in this research. In this research, we conducted a two-year field experiment to explore whether dripline spacing and fertilization rate would affect maize grain yield. ![]() Maximizing grain yields with effective fertilization technologies and minimizing nitrogen losses is essential in agroecosystems.
