“…Excessive nutrient supply wastes fertilizer, while insufficient supply decreases yield (Khanal et al ., 2014). The combined application of nitrogen and other fertilizers (especially phosphorus and potassium fertilizers) can effectively increase rice yield and nitrogen fertilizer use efficiency (Sun et al ., 2013). This requires balancing the plant's nutrient demand and nitrogen supply (especially soil nitrogen nutrition and nitrogen fertilizer application) throughout the growth period (Cui et al ., 2008).…”

Overuse of fertilizer is detrimental to the sustainability of crop production from an economic and environmental perspective. While rice side-deep fertilization technology can significantly improve fertilizer utilization efficiency, improve crop yield and reduce environmental pollution caused by improper use of fertilizer compared with conventional fertilization methods. Therefore, side-deep fertilization technology has an important role in the sustainable development of agriculture. This article describes fertilizer selection, side-deep fertilization devices and the effects of side-deep fertilization technology on rice plants and soil. We summarize the types and characteristics of side-deep fertilizers and their ratios and modes. The basic principles and characteristics of the key components of mechanical fertilization devices are described in detail, including fertilizer discharging devices (rotating disc type, outer groove wheel type, screw type), fertilizer conveying devices (pneumatic, mechanical forced type) and sensors. The effects and mechanisms of side-deep fertilization on rice growth, yield, quality, fertilizer utilization efficiency and soil microorganisms are summarized. Finally, based on current research on side-deep fertilization, future directions are identified to aid the development of this promising technology.

“…Among them, nitrogen is the primary limiting factor (Ren et al., 2021). Previous studies have shown that reasonable nitrogen fertilizer management can promote the synergistic absorption of many nutrients by drip‐irrigated rice, and increase the accumulation potential of dry matter and nitrogen, phosphorus, and potassium (Sun et al., 2011; Q. C. Zhu et al., 2013), thereby maintaining plant nutrient balance and ion homeostasis and improving crop productivity (Acharya & Pesacreta, 2023). Tang et al.…”

Improving the management of water and fertilizers is an effective method for enhancing the seed‐setting performance of rice. This study aimed to explore the regulation of optimized water and nitrogen management on the root‐leaf hormone balance and seed‐setting performance of drip‐irrigated rice. In a 2‐year field experiment, T‐43 (a drought‐resistant cultivar) and LX‐3 (a drought‐sensitive cultivar) were cultivated under two drip irrigation treatments (W1, limited, and W2, deficit) and three nitrogen fertilization treatments (N1, seedling:tillering:panicle:grain‐filling, 30%:50%:13%:7%; N2, 20%:40%:30%:10%; and N3, 10%:30%:40%:20%). Compared with other treatments, the W1N2 treatment increased the seed‐setting rate and grain biomass accumulation (2.7‐9.2% and 4.5‐69.8%) of the two cultivars on the basis of producing a higher effective panicle number, and T‐43 had a much higher seed‐setting rate and yield than LX‐3 (6.8‐14.6%). Increased fertilizer applications at the panicle and grain‐filling stages (N2) enhanced the root oxidation activity (ROA) and the zeatin+zeatin riboside (Z + ZR) and gibberellic acid (GA3) contents in the roots in the 0–10 cm layer and in the leaves from the heading stage to 20 d after heading. The grain biomass accumulation of T‐43 was significantly positively correlated with ABA and Z + ZR in the roots and leaves, while the grain biomass accumulation of LX‐3 was significantly positively correlated with IAA, ABA, Z + ZR/ABA and GA3/ABA in the roots in the 10–20 cm layer. Overall, W1N2 promoted grain biomass accumulation by modulating the Z + ZR and ABA balance in roots and leaves, improved the root–shoot ratio, and enhanced ROA, thereby improving the seed‐setting performance of drip‐irrigated T‐43 rice.This article is protected by copyright.

“…Compared with local farmers’ practice (LFP), field-specific nitrogen management and irrigation with alternate wetting and moderate drying not only improved grain yield but also nitrogen and water use efficiency ( Xue et al, 2013 ). Meanwhile, water and nitrogen fertilizer management had altered the magnitude of nitrogen, phosphorus, and potassium uptake in rice; significant synergistic effects of nitrogen, phosphorus, and potassium under the condition of water and nitrogen interaction were even observed ( Sun et al, 2011 ; Yu et al, 2019 ). Although water and nitrogen management measures are important management for fragrant rice production, there is still a lack of specific information in this regard.…”

The present study was conducted to assess the effects of water and nitrogen applications at the booting stage on yield, grain quality, and nutrient use efficiencies in fragrant rice in the early (March–July) and late (July–November) seasons of 2013. The experiment was comprised of two fragrant rice cultivars, i.e., Nongxiang 18 and Basmati; three nitrogen levels, i.e., 0 kg N ha−1 (N0), 30 kg N ha−1 (N1), and 60 kg N ha−1 (N2); and three water levels, i.e., 2–4 cm water layer well-watered (W0), water with a soil water potential of −15 ± 5 kPa (W1), and water with a soil water potential of −25 ± 5 kPa (W2), which were randomized in a split-split plot design. Results showed that Basmati produced a higher grain yield than Nongxiang 18 (16.20 and 9.61% in the early and late season, respectively), whereas the W1 exhibited the maximum grain yield and harvest index. The moderate application of nitrogen (N1) at the booting stage resulted in higher grain yield, nevertheless, cultivar, water, and nitrogen revealed different trends for some of the grain quality attributes, i.e., brown rice rate, milled rice rate, head milled rice rate, protein content, and amylose content as well as nutrient uptake and use efficiencies in the double rice production system. Basmati had a higher nitrogen harvest index (NHI; 18.28–20.23%) and P harvest index (PHI; 3.95–12.42%) but lower physiological P use efficiency for biomass (PPUEB; 7.66–23.66%) and physiological K use efficiency for biomass (PKUEB; 2.53–7.10%) than Nongxiang 18 in both seasons. Furthermore, the grain number per panicle, biomass yield, grain P uptake, and the whole plant P uptake were significantly related to the grain yield of fragrant rice. In both seasons, the interaction of water and nitrogen (W × N) had a significant effect on panicle number, grain quality attributes, and N, P uptake of straw, as well as the physiological N, P use efficiency for grain and the physiological N, K use efficiency for biomass. Overall, results suggest that moderate nitrogen and irrigation input at the booting stage could be feasible to improve the productivity and quality of the double rice production system with improved nutrient use efficiency under the agro-climatic conditions of South China.
