“…Compared with that under N1, the K grain productivity under N2 and N3 was significantly increased by 22.07 and 12.11%, respectively, whereas that under N4 was significantly decreased by 8.23%. Moe, Htwe, Thu, Kajihara, and Yamakawa (2019) found that when sufficient N and P were available, rice plants responded only to K in terms of yield. Our results are in line with those of the abovementioned study, which reported that a higher K uptake was associated with a higher rice yield.…”

Soil salinity and alkalinity are key abiotic stresses that limit crop growth and yield worldwide. Balanced N fertilization is important for improving rice (Oryza sativa L.) yield via efficient utilization of P and K under saline and alkaline soil conditions. In this study, a japonica rice cultivar, Kenjing 8, was used to investigate the effects of N fertilizer on rice yield, as well as N, P, and K status, in a 2‐yr field experiment in saline‐alkaline soil in Heilongjiang Province, northeast China. The plants were assigned to the following five treatment groups: no N fertilizer, or conventional, balanced, reduced, and postponed N fertilizer management. Compared with conventional N management practice, balanced and reduced N management practices increased the concentrations of N, P, and K in the leaves, stem‐sheaths, and panicles at full heading (FH) and maturity; however, postponed N management led to the opposite results. Balanced N management increased N, P, and K mobilization to the leaves (from FH to maturity) by 49, 43, and 67%, respectively, resulting in the highest crop yields among all the N management practices studied. Furthermore, rice yield was positively correlated with N, P, and K accumulation and rates of nutrient mobilization to the leaves, stem‐sheaths, and panicles at maturity. The application of 150 or 135 kg N ha−1, and the proportion of 4:3:1:2 in the pre‐transplanting, mid‐tillering, panicle initiation, and panicle differentiation stages, may increase rice yield and facilitate efficient utilization of nutrients in saline‐alkaline soil.

“…Summarizing, the results of the study indicated that the application of the proposed compost at the rate of 6 Mg ha −1 can be considered sufficient for the rice crop nutrient requirements even from the first year of application. In contrast, Moe et al [36] refer that organic fertilizers (like compost made from kitchen waste and bamboo) with total N < 4% were only effective at improving rice growth and yield in the second year, after being continuously applied for 2 years. In order to understand the socio-economic implications of the use of the novel compost, a cost analysis for its production was performed in 2016, during the preliminary phase of our study [37].…”

Rice is the major staple crop worldwide, whereas fertilization practices include mainly the application of synthetic fertilizers. A novel compost was developed using 74% of rice industrial by-products (rice bran and husks) and tested in rice cultivation in Greece’s main rice producing area. Field experimentation was conducted in two consecutive growing seasons (2017 and 2018) and comprised six fertilization treatments, including four compost rates (C1: 80, C2: 160, C3: 320 kg ha−1 of nitrogen all in split application, C4: 160 kg ha−1 of nitrogen in single application), a conventional treatment, as well as an untreated control. A total of 21 morpho-physiological and quality traits were evaluated during the experimentation. The results indicated that rice plants in all compost treatments had greater height (8%–64%) and biomass (32%–113%) compared to the untreated control. In most cases, chlorophyll content index (CCI) and quantum yield (QY) were similar or higher in C3 compared to the conventional treatment. C2 and C3 exhibited similar or greater yields, 7.5–8.7 Mg ha−1 in 2017 and 6.3–6.9 Mg ha−1 in 2018, whereas the conventional treatment resulted in 7.3 Mg ha−1 and 6.8 Mg ha−1 in the two years, respectively. No differences were observed in most quality traits that affect the rice commodity. The current study reveals that in sustainable farming systems based on circular economy, such as organic ones, the application of the proposed compost at the rate of 6 Mg ha−1 can be considered sufficient for the rice crop nutrient requirements.

“…Statistical analyses were done using the Statistical Tool for Agricultural Research (STAR) software for the analysis of variance (ANOVA). Tukey's honestly significant difference (HSD) test was used at P < 0.05 level of significance to test the differences among treatment means in each parameter (Moe et al 2019).…”

Background Hardsetting soils are considered problem soils due to its behavior of becoming hard and unbearable to cultivate not until rewetted. Few investigations were conducted in this kind of problem soil; hence, information about biomass yield and nutrient uptake is still elusive. This study investigated the impact of potentially hardsetting soil on the biomass yield and nutrient uptake of sweet corn under no-tillage cultivation system with varying fertilization treatments. Results The application of full NPK + 1 Mg ha−1 VC increased stover and grain yield by 26–106% and 11–135%, respectively. Approximately 64% and 112% of sweet corn stover and grain yield increased when treated with full NPK. Highly significant quadratic relationship (P < 0.001) was revealed between total biomass yield and nutrient uptake of sweet corn, implying that 98–99% of the variation in total biomass could be elucidated by its nutrient uptake. Further, this indicated the suitability of nutrient uptake function that could be used as an estimate in the progression of total biomass accumulation. The application of full NPK showed statistically significant (P < 0.001) nitrogen and phosphorus use efficiency across treatments. The soil in the experimental area was a potentially hardsetting soil due to its rapid soil strength development at least 4 days from wetting. This implies that with continued use, proper soil management must be implemented like reduced tillage and organic matter application to facilitate structure formation and binding of soil particles by labile fraction in organic matter. Conclusion Application of organic amendment in combination with inorganic fertilizer could be a sustainable production strategy on sweet corn production system in potentially hardsetting soil under no tillage through enhanced nutrient uptake and biomass accumulation.
