“…Maize (Zea mays L.) is one of the largest food staples worldwide and is one of the most economically important crops in China 1 . Maize yields as high as 260.77 billion kilograms have been attained in China, greatly contributing to ensuring food safety and increasing farmer income [2][3][4] . In China, the maize-sowing area reached approximately 44.96 million hm 2 in 2015, after which it decreased to 42.39 million hm 2 in 2017 5 .…”

To elucidate the symptoms and pathogens diversity of corn Fusarium sheath rot (CFSR), diseased samples were collected from 21 county-level regions in 12 prefecture-level districts of Sichuan Province from 2015 to 2018 in the present study. In the field, two symptom types appeared including small black spots with a linear distribution and wet blotches with a tawny or brown color. One hundred thirty-seven Fusarium isolates were identified based on morphological characteristics and phylogenetic analysis (EF1-α), and Koch’s postulates were also assessed. The results identified the isolates as 8 species in the Fusarium genus, including F. verticillioides, F. proliferatum, F. fujikuroi, F. asiaticum, F. equiseti, F. meridionale, F. graminearum and F. oxysporum, with isolation frequencies of 30.00, 22.67, 15.33, 7.33, 6.00, 5.33, 3.33 and 1.33%, respectively. Fusariumverticillioides and F. proliferatum were the dominant and subdominant species, respectively. Two or more Fusarium species such as F. verticillioides and F. proliferatum were simultaneously identified at a mixed infection rate of 14.67% in the present study. The pathogenicity test results showed that F. proliferatum and F. fujikuroi exhibited the highest virulence, with average disease indices of 30.28 ± 2.87 and 28.06 ± 1.96, followed by F. equiseti and F. verticillioides, with disease indices of 21.48 ± 2.14 and 16.21 ± 1.84, respectively. Fusarium asiaticum, F. graminearum and F. meridonale showed lower virulence, with disease indices of 13.80 ± 2.07, 11.57 ± 2.40 and 13.89 ± 2.49, respectively. Finally, F. orysporum presented the lowest virulence in CFSR, with a disease index of 10.14 ± 1.20. To the best of our knowledge, this is the first report of F. fujikuroi, F. meridionale and F. asiaticum as CFSR pathogens in China.

“…For instance, the origin of maize germ is expected to markedly affect the life cycle performance of the maize refined oil production chain. Even though uncertainties arise from the use of different calculation methods [48], the different agricultural practices adopted for maize germ production significantly affect the environmental performances, by involving the use of different amounts of fertilizers and pesticides [48,49]. Nonetheless, site-specific data are needed to assess these impacts because of the relevant role played by local factors, such as soil characteristics [50] and local yield responses of different maize genotypes to fertilizer applications [51].…”

The need to reduce the environmental impacts of the food industry is increasing together with the dramatic increment of global food demand. Circulation strategies such as the exploitation of self-produced renewable energy sources can improve ecological performances of industrial processes. However, evidence is needed to demonstrate and characterize such environmental benefits. This study assessed the environmental performances of industrial processing of maize edible oil, whose energy provision is guaranteed by residues biomasses. A gate-to-gate Life Cycle Assessment (LCA) approach was applied for a large-size factory of Northern Italy to describe: (i) the environmental impacts related to industrial processing and (ii) the contribution of residue-based bioenergy to their mitigation, through the comparison with a reference system based on conventional energy. The results showed that oil refinement is the most impacting phase for almost all the considered impact categories. The use of residue-based bioenergy was found to drastically reduce the emissions for all the impact categories. Moreover, Cumulative Energy Demand analysis revealed that the use of biomass residues increased energy efficiency through a reduction of the total energy demand of the industrial process. The study demonstrates that the exploitation of residue-based bioenergy can be a sustainable solution to improve environmental performances of the food industry, while supporting circular economy.

“…The study was conducted as a factorial combination of two mulch levels (mulch and no mulch) and three maize cultivars. The three maize cultivars were Dafeng 26 (DF), Xianyu 335 (XY), and Tianci 19 (TC) (Qi et al., 2018). The experimental design was set up according to randomized complete block design (RCBD) with four replications.…”

Millions of small farmers rely on maize (Zea mays L.) produced in the Loess Plateau of China. The purpose of this study was to find a fine maize variety in the Check Dam and to reveal the reasons for the effects of white plastic film mulch and maize varieties on crop yield and photosynthetic characteristics. Three maize cultivars (Dafeng 26 [DF], Xianyu 335 [XY], and Tianci 19 [TC]) were grown with and without plastic mulch in 2016 and 2017 in Ansai County, Shaanxi Province, China. Results showed that mulch increased grain yield by 10.5% in 2016 and 11.3% in 2017 across all cultivars. Among all cultivars, XY had the highest grain yield under both mulch and no mulch. Grain yield was significantly correlated with soil water content in the 0-20 cm layer. Soil temperature under mulch decreased with increasing soil depth. On average, mulch increased soil temperature from 0.2 to 1.9 • C over the entire growing season. Photosynthetic characteristics were directly determined for all tested maize cultivars. Grain yield was more closely related to photosynthetic rate in July (r = .828, P = .001; n = 12) than in August (r = .617, P = .032; n = 12). Moreover, grain yield was correlated with stomatal conductance and transpiration rate in July and August (r = .913-.928, P < .001; n = 12). Our findings suggest that photosynthetic characteristics were an important index affecting maize grain yield for small farmers using check dams in the Loess Plateau.
