Nitrogen fertilization is commonly used by growers in these regions to obtain optimal wheat yields, but it is unclear how various methods may affect CH₄ absorption. Therefore, we conducted two years of field studies in the rain-fed agricultural experimental station in the semi-arid Loess Plateau in northwest China to test how four fertilization methods altered different crop and soil characteristics. Plots consisted of a popular spring wheat variety treated with either no fertilizer (CK), nitrogen fertilizer (N), organic manure (M), or a combination of nitrogen and organic manure (NM). We analyzed the effects each fertilization methods had on both yield and soil CH₄ flux. The results indicated that these soils act as a net sink of CH₄. The NM treatment significantly increased wheat yield, while the N treatment significantly reduced CH₄ absorption. Furthermore, soil CH₄ absorption under each treatment had a clear temporal pattern, which peaked during the flowering stage. Our principal component analysis and linear regression analysis illustrated how CH₄ fluxes were significantly positively or negatively correlated with soil total nitrogen, nitrate nitrogen, and temperature (<i>P</i> &lt; 0.05), potentially explaining 40% of the CH₄ variability. In conclusion, our results indicate that the co-application of nitrogen and organic manure can both support optimal wheat yield and effectively reduce the risk of CH₄ emissions.</p>","PeriodicalId":54947,"journal":{"name":"International Journal of Plant Production","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2024-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139759936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In sorghum, the biochemical traits, such as the proline content, may play a more critical role in withstanding water-limited conditions than in maize in our experiment. Under the same water restriction period, sorghum showed higher RWC levels. Sorghum plants reduced stomatal density under more water-limited conditions, which proves its plasticity. Additionally, early maturation played a crucial role in both species. The early sorghum variety KWS Kallisto and maize variety Walterinio KWS had a more stable yield at both sites.

Therefore, the aim of this study is to characterize the morphological and physiological traits of underutilized crops under different nutrient amendments towards the dry conditions.

It is of great significance to quantify crop water stress severity by using the response characteristics of leaf gas exchange to drought. However, it is currently unclear whether leaf gas exchange serve as a reliable indicator for predicting crop final yield in response to drought, which affects the accuracy of monitoring agricultural drought using physiological indicators during the crop growing season. This study determined the response threshold of leaf gas exchange to drought for spring wheat through a serials of soil dry-down experiments and used the threshold characteristics to construct and parameterize a spring wheat growth model. Spring wheat were designed to be irrigated with five treatments (with supplementary irrigation at 230 mm, 165 mm, 115 mm, 50 mm and 0 mm). Crop model were used to simulate and analyze the threshold response characteristics of grain yield to drought and compare them to the thresholds of leaf gas exchange indices for spring wheat. The results showed that the response threshold of stomatal conductance of spring wheat to fraction of transpirable soil water was 0.5, which was greater than that of transpiration rate and net photosynthetic rate, 0.4. The parameterized spring wheat growth model with the response threshold of net photosynthetic rate to fraction of transpirable soil water accurately simulated the aboveground biomass and final yield of spring wheat. The response threshold of spring wheat final yield to fraction of transpirable soil water was significantly smaller than that of leaf gas exchange parameters to fraction of transpirable soil water (0.18 versus 0.4). This indicates that there are certain problems in using physiological indicator such as leaf gas exchange indices during crop growing season to determine the agricultural drought severity and reflect the reduction of final crop yields due to drought.</p>","PeriodicalId":54947,"journal":{"name":"International Journal of Plant Production","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2024-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139459344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The response of various nitrogen (N) levels (0, 25, 50, 75, and 100 kg ha^− 1) was studied on the growth and yield of three rice cultivars (Guard Lp-02, Guard Lp-18, and Super Fine) grown as ratoon rice.

The soybean sowing in soil containing high amounts of grass straw can lead to mineral N temporary immobilization at the beginning of the crop cycle. Some farmers apply N fertilizers at soybean sowing, often combined with seed inoculation with <i>Bradyrhizobium</i> spp. to circumvent that limitation. The objective of this work was to evaluate the effects of N fertilization at soybean sowing cultivated after different off-season crops or after fallow on soybean yield and grain protein and oil concentrations. The field experiment installed in Londrina, Paraná, Brazil, lasted seven years. The treatments were plots unfertilized or fertilized with 30 kg ha⁻¹ N at soybean sowing with five land uses in the off-season: (i) corn for grain production with N (80 kg ha⁻¹) broadcasted, (ii) corn for grain production without N fertilization, (iii) wheat for grain production without N fertilization, (iv) ruzigrass (<i>Urochoa ruziziensis</i>) as a cover crop, and (v) unplanted fallow. Results showed no interaction between soybean N fertilization and off-season crops on any variable. Soybean N fertilization did not affect grain yield (mean of 4064 kg ha⁻¹ without N and 4136 kg ha⁻¹ with N fertilization) in any of the seven seasons, including when the yield average was higher than 4500 kg ha⁻¹, which implies a high N demand for grain production. N applied at soybean sowing did not influence grain protein or oil concentration. Off-season cultivation of ruzigrass and wheat resulted in higher soybean yields (4354 and 4304 kg ha⁻¹, respectively) than off-season cultivation of corn with or without N and fallow (4058, 3942, and 3843 kg ha⁻¹, respectively). Soybean protein concentration (367 g kg⁻¹) was highest after ruzigrass and lowest (354 g kg⁻¹) after fallow. Soybean cultivated after N-fertilized corn yielded the maximum oil concentration (222 g kg⁻¹) and rendered the minimum (216 g kg⁻¹) after wheat.

The morphological indicators, photosynthetic characteristics, and the nutrient contents were determined at the stages of the leafage growing period (V1), sugar increase period of taproot (V2), sugar accumulation period I of taproot (V3), and sugar accumulation period II of taproot (V4), and the root yield and quality parameters were measured at the harvest. The results showed that in the plant spacing treatments of 11 and 14 cm, sugar beet had a suitable canopy structure and space for taproot growing. The canopy photosynthetic activity was higher, which provided sufficient photosynthetic products for root growth, and appropriate root size could balance root growth and sucrose accumulation. The highest root yield and sugar content were also obtained in the treatment of 14 cm plant spacing. With the increase of plant spacing, the yield of sugar beet decreased, and the content of α-amino N, K⁺, and Na⁺ in the root increased, which had a disadvantageous influence on the processing quality of the root. It was found that the number of cambial rings and the average distance between cambial rings could be used as qualitative indicators of the sugar content of taproot and the processing quality.
