“…This method of laser pre-sowing treatment of crop seeds can improve a plant’s physiological activity and increase crop yield ( Kouchebagh et al, 2014b ). Currently, this treatment is generally considered less harmful to the environment than other methods because it only modifies the seed’s physiological and natural biochemical processes ( Hanafiah, Mohamad & Aziz, 2018 ; Harun, Hanafiah & Aziz, 2020 ). In addition, the availability of various laser wavelengths has grown in recent years.…”

Background Laser applications in agriculture have recently gained much interest due to improved plant characteristics following laser treatment before the sowing of seeds. In this study, maize seeds were exposed to different levels of laser treatment prior to sowing to improve their field performance. The aim of this study is to evaluate the impact of pre-sowing laser photobiomodulation on the field emergence and growth of treated maize seeds. Methods The maize seeds were first photobiomodulated with two lasers: 1) a helium-neon (He–Ne) red laser (632.8 nm), and 2) a neodymium-doped yttrium aluminum garnet (Nd:YAG) green laser (532 nm). Following three replications of randomized complete block design (RCBD), four irradiation treatments were applied (45 s, 65 s, 85 s, and 105 s) at two power intensities (2 mW/cm2 and 4 mW/cm2). Results Based on the results, maize seeds pretreated with a green laser and 2 mW/cm2 power intensity for 105 s exhibited the highest rate of seed emergence (96%) compared to the untreated control seeds with a lower seed emergence rate (62.5%). Furthermore, maize seeds treated with a red laser for 45 s showed an increased vigor index compared to the other treatment options and the control (P < 0.01). The treatment groups also showed statistically significant differences in seedling growth characteristics compared to the control group p < 0.01. The green laser produced a significant enhancement of about 24.20 cm in seedling length, 8.2 leaves/plant, and 3.4 cm in stem diameter compared to the untreated seeds. Moreover, the green laser treatment showed 57.4 days to anthesis, which was earlier than the untreated seeds (61.4 days). The results showed that the protein, oil, and starch contents of the seeds irradiated with the green laser were 17.54%, 6.18%, and 73.32%, respectively, compared to the seeds irradiated by the red laser with 16.51%, 6.33%, and 71.05%, respectively. Conclusions The photo biomodulation of maize seeds using a green laser light can improve the field emergence, seedling growth, and seed quality of the treated seed compared to the red laser treatment.

“…These empirical studies have been conducted for individual countries, i.e. Malaysia (Harun et al, 2021;Sarkar et al, 2020), Indonesia (Panuju et al, 2013;Takahashi and Barrett, 2014), and Thailand (Boonwichai et al, 2019;Chiarawipa and SDOODEE, 2020). However, our study focuses on all these 4 countries to see whether climate change causes any disruption in their agricultural production.…”

“…Of these, most come from Asia (52%), especially China (16%), Thailand (8%) and Japan (7%). In most of the studies published in the last six years, conventional rice production was compared with organic rice production, e.g., Nunes et al, 2017 [45]; He et al, 2018 [46]; Harun et al, 2021 [47]. In this regard, He et al, (2018) [46] evaluated through LCA China's conventional and organic rice production, showed that conventional production produces less environmental benefits than organic production, up to ten times more impact due to the use of chemical fertilizers [45,[48][49], as well as on global warming and soil occupation due to organic fermentation.…”

“…The former is produced by methanogenesis and flooding of the paddy field, which produces fermentation of the aerobic matter, while the latter are emitted with the use of nitrogen fertilizers. Climate-changing emission levels are also fueled by the use of diesel-powered machinery during the planting phase, which is the last identified hotspot in rice production [45,47,50].…”

Cereals have been the basis of human and animal nutrition for centuries, and according to the Intergovernmental Panel on Climate Change (IPCC) (2020), between 1961-2019 their global production increased by +240%, reaching about 3 billion tons, accounting for 18% of climate-changing emissions from the agro-food sector. Continued population growth will lead to the need to produce more food, and to keep up it is estimated that cereal production will need to increase by 900 million tons by 2050, posing an inevitable increase in environmental pressures. Therefore, the new challenge will be to reconcile increased production with sustainable agricultural practices, in line with the Sustainable Development Goals (SDGs) and the new Common Agricultural Policy (CAP). Since cereal production is essential to produce globally relevant commodities, it is important to assess and study its associated environmental effects. In this context, the Life Cycle Assessment (LCA) is recognized by the international scientific community as a useful tool for the assessment of environmental impacts caused by products, processes or systems and for the validation of new production paradigms. Therefore, the aim of this research is to carry out an overview of the literature on the most recent applications of LCA related to the production of cereals, in order to highlight the main criticalities, also according to the different production methods of the various Countries. Therefore, the three major cereals (corn, wheat and rice) and five minor ones (barley, sorghum, millet, oats and rye) were considered and the results showed that for all crops the main hotspot is the application and use of fertilizers. However, studies often differed in terms of functional unit, impact assessment methods, and respective environmental indicators. Therefore, a complete comparison was not always possible. Finally, the literature overview did not identify studies in which the social impacts of cereal production were considered, although economic assessments are present in some cases. Therefore, it is believed that consistent with the achievement of the SDGs, it is desirable to apply Social Life Cycle Assessment (S-LCA) in agricultural and development policies to consider not only environmental impacts, but also economic and social impacts, in order to ensure a truly sustainable development and thus on all three dimensions
