Enhancing rice yield, quality and nitrogen utilization through side-deep placement of nitrogen and zinc fertilizers
Nitrogen (N) surface-broadcasting often leads to N loss, reducing N utilization and harming the environment. Side-deep fertilization can mitigate N loss and fertilizer use but may occasionally compromise rice yields due to variable N availability. Integrating zinc (Zn) with N fertilization enhances both N utilization and rice yields through synergistic N-Zn interactions. However, the combined effects of side-deep placement of N with Zn on rice grain yield, quality, and N utilization remain underexplored. Therefore, a two-year field trial was conducted in the Yangzhou district of Jiangsu province, China, with five treatments: control with no N input (CK), surface-broadcast N fertilizer (T1), surface-broadcast combined N and Zn fertilizer (T2), side-deep N fertilizer (T3), and side-deep combined N and Zn fertilizer (T4). Compared with T1, T2-T4 significantly increased rice yield by 4.6 %-7.1 %, driven by higher panicle numbers, spikelets per panicle, seed-setting rate, and 1000-grain weight. T2 and T4 also promoted greater biomass accumulation, increased leaf area index, and delayed leaf senescence during grain filling, boosting yield formation. Moreover, T4 significantly enhanced the activities of key photosynthetic enzymes (RubisCO, RuBPcase, GoGAT, GS, NR, and POD) by 23.2 %-54.0 % compared with T1. These increases were closely associated with improved N and Zn uptake, leading to higher photosynthetic efficiency. T4 also improved grain quality by increasing brown rice rate, milled rice rate, head rice rate, and taste value by 1.5 %-8.0 %, while reducing chalky grain percentage and chalkiness degree by 6.5 % and 15.9 %, respectively. Additionally, N recovery efficiency (NRE) and aboveground Zn accumulation increased by 19.7 % and 46.0 %, respectively. In conclusion, side-deep placement of N with Zn supplementation is a powerful agronomic strategy that enhances rice yield, improves grain quality, and optimizes N utilization. This practice is crucial for advancing high-quality, high-yield rice cultivation.
