“…N release from SCU and RCU was studied in a pool under the same conditions as the lotus planting. Nitrogen release after fertilization was studied by soil embedding [ 63 ]. The fertilizer weighing 10 g was placed into a nylon gauze bag (120 mm × 60 mm) with a hole diameter of 0.15 mm.…”

Slow-release fertilizer is an environmentally friendly fertilizer that is widely used in crop cultivation instead of traditional nitrogen fertilizer. However, the optimal application time of slow-release fertilizer and its effect on starch accumulation and rhizome quality of lotus remains unclear. In this study, two slow-release fertilizer applications (sulfur-coated compound fertilizer, SCU, and resin-coated urea, RCU) were fertilized under three fertilization periods (the erect leaf stage, SCU1 and RCU1; the erect leaf completely covering the water stage, SCU2 and RCU2; and the swelling stage of lotus rhizomes, SCU3 and RCU3) to study the effects of different application periods. Compared with CK (0 kg∙ha−1 nitrogen fertilizer), leaf relative chlorophyll content (SPAD) and net photosynthetic rate (Pn) remained at higher levels under SCU1 and RCU1. Further studies showed that SCU1 and RCU1 increased yield, amylose content, amylopectin and total starch, and the number of starch particles in lotus, and also significantly reduced peak viscosity, final viscosity and setback viscosity of lotus rhizome starch. To account for these changes, we measured the activity of key enzymes in starch synthesis and the relative expression levels of related genes. Through analysis, we found that these parameters increased significantly under SCU and RCU treatment, especially under SCU1 and RCU1 treatment. The results of this study showed that the one-time application at the erect leaf stage (SCU1 and RCU1) could improve the physicochemical properties of starch by regulating the key enzymes and related genes of starch synthesis, thus improving the nutritional quality of lotus rhizome. These results provide a technical choice for the one-time application of slow-release fertilizer in lotus rhizome production and cultivation.

“…The development of a slow-release fertilizer (SRF) fulfills the above goal and provides a new direction for more efficient and simplified fertilization of wheat [16]. By employing different coating materials or adding inhibitors, SRF can release N into the soil solution at a rate matching the plant demand, thereby reducing excess inorganic N accumulation and N loss from the soil profile [17,18].…”

Environmental conditions (precipitation, temperature and soil properties) differ greatly in different regions and have dual effects on the wheat growth and nutrient release of slow-release fertilizer (SRF). Conventional fertilization methods such as the multiple-split application of urea and the one-time application of SRF may have difficulty achieving a stable and high wheat yield and nitrogen (N) efficiency in various environments. Therefore, the exploration of a rational application strategy of SRF is needed for improving wheat yield and its stability in different regions. A two-year field experiment was conducted in different regions (eight test sites per year) with five patterns: 100% N (270 kg ha−1) SRF applied pre-sowing (M1); 60% N SRF applied pre-sowing and 40% N urea applied at jointing (M2); 60% N SRF applied pre-sowing and 40% N SRF applied at re-greening (M3); M2 reducing the N rate by 15% (M4); M3 reducing the N rate by 15% (M5). The fourth-split application of urea was taken as the control (CK, 270 kg N ha−1). The results suggested that the average yield in M1 decreased by 3.65% of the CK, and the yield stability was poor. Both M2 and M3 significantly increased N efficiency, grain yield and benefit, but the stability of M3 was higher than that of M2 in different environments. Considering further improvements in wheat yield, N efficiency and profit, our results suggested that the twice-split application of SRF, which also improved the adaptability of wheat in different environments, could be recommended for wheat cultivation.

“…Many studies have demonstrated that CRNF significantly increases rice yield (Wu et al, 2021; Ye et al, 2013) and N‐use efficiency (NUE) (Geng et al, 2015; Ni et al, 2011) in comparison to conventional urea. The use of CRNFs could promote the reduction of the emission of greenhouse gases (Wang et al, 2016).…”

Limited information is available on the influence of a one-time application of controlled-release nitrogen fertilizer (CRNF) in improving both yield and quality of rice. In this study, two rice cultivars, Jia58 (J58) and Jia67(J67), were used to study the effects of six combinations of short-acting (40-60-day release periods) and a long-acting (80-120-day release periods) CRNF. The six combinations were as follows: A1, 40-day + 80-day CRNFs; A2, 40-day + 100-day CRNFs; A3, 40-day + 120-day CRNFs; B1, 60-day + 80-day CRNFs; B2, 60-day + 100-day CRNFs; and B3, 60-day + 120-day CRNFs. Each combination of CRNFs was mixed with common urea (CU) to apply as basal fertilizer to rice crops to assess grain yield and quality. In addition, CU without CRNFs was applied as the control (CK). The results showed that the release of nitrogen from A2 and B2 were most matched with nitrogen accumulation by rice resulting in a higher yield (B2 treatment) or the same yield (A2 treatment) as CK. The average yield of 2 years of J58 in B2 was 7.38% higher than that of the CK. Similarly, the average yield of J67 in B2 was 6.46% higher than CK for both years. Milling quality, appearance quality, milled rice starch content, and taste value of rice in CRNF treatments were significantly higher than CK. In contrast, protein, gliadin, and glutenin contents and hardness of rice in the CRNF treatments were lower than CK. The higher protein content of rice in the CK resulted in higher gelatinization temperature and harder rice, which may explain why the eating and cooking qualities of rice in the CK were lower than those of rice in the CRNF treatment. These results demonstrate that the A2 and B2 treatments can produce improvements in both yield and quality of rice.
