To assess the effect of tilling and fertilization practices in the wheat-maize cropping systems, we carried out a three-year field experiment designed to quantify the carbon footprint (CF), and energy efficiency of the cropping systems in the North China Plain. As the study parameters, we used four tillage practices (no tillage (NT), conventional tillage (CT), rotary tillage (RT) and subsoiling rotary tillage (SRT)), and two fertilizer regimes (inorganic fertilizer (IF), and hybrid fertilizer with organic and inorganic components (HF)). Our results indicated that the most prominent energy inputs and greenhouse gas (GHG) emissions could be ascribed to the use of fertilizers and fuel consumption. Assuming the same fertilization regime, ranking the tillage patterns with respect to the value of the crop yield, the profit, the CF, the energy use efficiency (EUE) or the energy productivity (EP) for either wheat or maize always gave the following result: SRT>RT>CT>NT. For the same tillage, the energy consumption associated with HF was higher than IF, but its GHG emissions and CF were lower while the yield and profit were better. In terms of the overall performance, tilling is more beneficial than NT, and reduced tillage (RT and SRT) are more beneficial than CT. The fertilization regime with the best overall performance was HF. Combining SRT with HF has significant potential for reducing CF and increasing EUE, improving the sustainability. Adopting measures promoting these optimizations can help overcome the challenges posed by lack of food security, energy crises and ecological stress.","PeriodicalId":16305,"journal":{"name":"Journal of Integrative Agriculture","volume":"20 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140056857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the impact of delayed sowing date (DS) on rice quality may vary by variety and ecological conditions. In this study, we conducted experiments using different sowing dates, that is, conventional sowing date 1 (CS1), CS2 (10 d later than CS1), DS1 (30 d later than CS1), and DS2 (30 d later than CS2), and three rice varieties, i.e., “Yixiangyou 2115,” “Fyou 498,” and “Chuanyou 6203.” This experiment was conducted at four sites in the Sichuan basin in 2018 and 2019 to evaluate the influence of DS on the pasting properties of rice, which are a proxy for eating and cooking quality (ECQ). In DS1 and DS2, rice had a significantly greater amylose content (AC) but a lower protein content (PC), peak viscosity (PKV), cool paste viscosity (CPV), and hot paste viscosity (HPV) than in CS1 and CS2. Moreover, with the exception of CS2 and DS1 in 2018, DS1 and DS2 led to a 2.15–11.19% reduction in breakdown viscosity (BDV) and a 23.46–108.47% increase in setback viscosity (SBV). However, the influence of DS on rice pasting properties varied by study site and rice variety. In 2019, DS1 and DS2 led to a BDV reduction of 2.35–9.33, 2.61–8.61, 10.03–17.78, and 2.06–8.93%, and a SBV increase of 2.32–60.93, 63.74–144.24, 55.46–91.63, and -8.28–65.37% at the Dayi, Anzhou, Nanbu, and Shehong, respectively. DS resulted in a greater decrease in PKV, HPV, CPV, and BDV and a greater increase in the AC and SBV for Yixiangyou 2115 than for Chuanyou 6203 and Fyou 498. Correlation analysis indicated that PKV and HPV were significantly and positively related to the mean, maximum, and minimum temperatures after heading. These temperatures have to be greater than 25.9, 31.2, and 22.3℃ to increase the relative BDV and decrease the relative SBV of rice, thereby enhancing ECQ. In conclusion, DS might contribute to a significant deterioration in ECQ in machine-transplanted rice in the Sichuan basin. A mean temperature above 25.9℃ after heading is required to improve the ECQ of rice.","PeriodicalId":16305,"journal":{"name":"Journal of Integrative Agriculture","volume":"125 20 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140057081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key volatile compound responsible for the fragrance in fragrant rice is 2-acetyl-1-pyrroline (2-AP), which is significantly affected by field management measures. The purpose of this study was to investigate the impact of tillage management and straw returning on the grain yield and biosynthesis of 2-AP in fragrant rice. This study was conducted over two years in 2016 and 2017 and utilized two fragrant rice cultivars (Meixiangzhan 2 and Xiangyaxiangzhan) as materials. It consisted of different tillage managements and straw returning treatments, which included three tillage managements: rotary tillage (T0), minimum tillage (T1), and no tillage (T2), and two straw returning treatments: without straw returning (S0) and straw returning (S1). The straw used for the experiment was sourced from the residue of the early season harvested corresponding fragrant rice cultivar. Tillage management and straw returning substantially affected the grain yield, grain quality, and 2-AP content of both fragrant rice cultivars. Compared with the T0S0 treatment, tillage management and straw returning resulted in an improvement in the 2-AP content in 2016 (12.41-116.85%) and 2017 (34.85-103.89%) on average. A higher content of 2-AP was detected in both fragrant rice cultivars in the T2S1 and T1S1 treatments. A structural equation model (SEM) demonstrated that the enzyme activities of fragrance metabolism in the leaves and grain jointly regulated the biosynthesis of precursors of fragrance metabolism in the grain, which further promoted the accumulation of 2-AP. In addition, a principal component analysis indicated that the T1S1 treatment positively correlated with both 2-AP and grain yield. The SEM demonstrated that the enzymes related to nitrogen metabolism, parameters related to photosynthesis, and yield component contributed to the grain yield. The T1S1 treatment resulted in the highest average grain yield of 760.75 g m, which can be attributed to an increase in various attributes, such as the leaf area index, SPAD value, nitrogen metabolism, panicle number per m, and grain number per panicle. The minimum tillage and straw returning (T1S1) treatment is more effective at simultaneously improving both the grain yield and 2-AP content in fragrant rice.","PeriodicalId":16305,"journal":{"name":"Journal of Integrative Agriculture","volume":"49 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140056856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Organic fertilizer plays a key role in improving soil quality and stabilizing maize yields, but studies that refine different substitution rates remain poorly documented.

The experiment included five organic fertilizer N substitution rates with equal input of 200 kg N ha: 0% organic fertilizer (T1, 100% inorganic fertilizer), 50.0% organic+50.0% inorganic fertilizer (T2), 37.5% organic+62.5% inorganic fertilizer (T3), 25.0% organic+75.0% inorganic fertilizer (T4), 12.5% organic+87.5% inorganic fertilizer (T5), and no fertilizer control (T6).

Kernel traits, such as grain length, grain width, and thousand grain weight, are crucial for barley yield and quality. Cloning kernel traits related genes and identifying superior alleles for them are essential for marker-assisted selection in barley breeding. In the present study, was cloned from barley according to the known rice gene. Functional validation of based on the EMS mutants of barley landrace “Hatiexi” proved that it played an important role in grain length. Using a panel consisting of 363 barley accessions, candidate gene-based association analysis was explored to identify superior haplotypes for . The results showed that Hap3 was the superior haplotype for both grain length and thousand grain weight, and Hap4 was also the superior haplotype for thousand grain weight. In conclusion, the genotypes carrying the superior allele are important gene donators, and the molecular markers identified in this study will be helpful for grain size and yield improvement in barley breeding.","PeriodicalId":16305,"journal":{"name":"Journal of Integrative Agriculture","volume":"274 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140056858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
