“…Various parts of these plants, including the seeds, roots, stems, leaves, bark, and flowers, are used [221]. The plants used for biostimulants are rich in phytohormones, antioxidants, minerals, amino acids, and many other bioactive compounds with nutritional and growth-promoting potential [222]. Their mechanism of action involves releasing phosphorus (P) from soils, triggering the metabolism of nitrogen (N), promoting root growth, regulating hormones, and enhancing soil microbial activity [223].…”

In recent years, the progressive escalation of climate change scenarios has emerged as a significant global concern. The threat to global food security posed by abiotic stresses such as drought, salinity, waterlogging, temperature stress (heat stress, freezing, and chilling), and high heavy metal accumulation is substantial. The implementation of any of these stresses on agricultural land induces modifications in the morphological, biochemical, and physiological processes of plants, leading to diminished rates of germination, growth, photosynthesis, respiration, hormone and enzyme activity disruption, heightened oxidative stress, and ultimately, a reduction in crop productivity. It is anticipated that the frequency of these stresses will progressively escalate in the future as a result of a rise in climate change events. Therefore, it is crucial to develop productive strategies to mitigate the adverse effects of these challenges on the agriculture industry and improve crop resilience and yield. Diverse strategies have been implemented, including the development of cultivars that are resistant to climate change through the application of both conventional and modern breeding techniques. An additional application of the prospective and emerging technology of speed breeding is the acceleration of tolerance cultivar development. Additionally, plant growth regulators, osmoprotectants, nutrient and water management, planting time, seed priming, microbial seed treatment, and arbuscular mycorrhiza are regarded as effective methods for mitigating abiotic stresses. The application of biochar, kaolin, chitosan, superabsorbent, yeast extract, and seaweed extract are examples of promising and environmentally benign agronomic techniques that have been shown to mitigate the effects of abiotic stresses on crops; however, their exact mechanisms are still not yet fully understood. Hence, collaboration among researchers should be intensified to fully elucidate the mechanisms involved in the action of the emerging technologies. This review provides a comprehensive and current compilation of scientific information on emerging and current trends, along with innovative strategies to enhance agricultural productivity under abiotic stress conditions.

“…Moringa leaf extract contains bioactive compounds, including phytohormones such as cytokinins and gibberellins (Yuniati et al, 2022). Foliar application of the moringa leaf extract can lead to the plant's uptake and assimilation of these phytohormones (Irshad etal., 2022;Islam et al, 2022). 3.…”

A field trial was conducted during the summer of 2021 at the Agronomy Research Farm, The University of Agriculture Peshawar, to investigate the impact of seed priming with different concentrations of moringa leaf extract on sweet corn landraces. The experiment used a randomized complete block design with three replications to assess various phenological, growth, and yield parameters. Results showed that seed priming with a 10% moringa leaf extract solution significantly influenced sweet corn phenology. The primed seeds exhibited earlier emergence (7.5 days), tasseling (55.9 days), silking (62.6 days), and physiological maturity (88.3 days) compared to the unprimed seeds (emergence: 9.2 days, tasseling: 59.4 days, silking: 66.5 days, physiological maturity: 90.9 days). Furthermore, the 10% moringa leaf extract priming treatment resulted in superior growth and yield parameters. It led to maximum plant height (181.9 cm), number of ears (10 m-2), number of grains per ear (372), thousand-grain weight (174.2 g), biological yield (9912 kg ha-1), grain yield (2985 kg ha-1), and harvest index (30.1%). Conversely, the unprimed seeds had lower values for these parameters (plant height: 172.7 cm, number of ears: 8 m-2, number of grains per ear: 354, thousand-grain weight: 167.1 g, biological yield: 9423 kg ha-1, grain yield). Among the sweet corn landraces tested, the Kashmir variety exhibited earlier phenological stages (emergence: 7.8 days, tasseling: 56.2 days, silking: 63.2 days, physiological maturity: 88.6 days) compared to the Kunarh landrace (emergence: 8.6 days; tasseling: 58.6 days, silking: 65.3 days, physiological maturity: 90.1 days). Additionally, the Kashmir landrace demonstrated higher values for plant height (180.0 cm), number of ears (10 m-2), number of grains per ear (368), thousand-grain weight (173.0 g), biological yield (9923 kg ha-1), grain yield (3008 kg ha-1), and harvest index (30.3%) compared to the Kunarh landrace (plant height: 175.8 cm, number of ears: 9 m-2, number of grains per ear: 360, thousandgrain weight: 168.4 g, biological yield: 9540 kg ha-1, grain yield: 2782 kg ha-1, harvest index: 29.2%). It was concluded that pre-sowing seed treatments could improve seed quality, yield, and growth performance of sweet corn landraces and that landraces have the potential for cultivation and improvement.

Increasing the productivity of cereals such as maize while protecting the environment remains a fundamental impetus of healthy food production systems. The use of biostimulants is one of the sustainable strategies to achieve this balance, although the ability of biostimulants to enhance maize productivity varies. Moreover, research on the efficacy of biostimulants is ubiquitous with limited comprehensive global analysis. In this context, this systematic review evaluated the sole and interactive effects of biostimulants on the yield and quality of maize grain from a global perspective. Changes in yield (t ha-1), protein content (%), starch content (%) and oil content (%) of maize grain were assessed. Results revealed that sole and combined application of biostimulants significantly improved grain yield. Irrespective of the region, the highest and the lowest grain yields ranged between 16-20 t ha-1 and 1-5 t ha-1, respectively. In sole application, the promising biostimulants were chicken feather (16.5 t ha-1), and endophyte Colletotrichum tofieldiae (14.5 t ha-1). Sewage sludge × NPK (15.4 t ha-1), humic acid × control release urea (12.4 t ha-1), Azospirillum brasilense or Bradyrhizobium japonicum × maize hybrids (11.6 t ha-1), and Rhizophagus intraradices × earthworms (10.0 t ha-1) had higher yield for the interactive effects. The effects of biostimulants on grain quality were minimal, and all attributes improved in the range from 0.1 to 3.7%. Overall, biostimulants had a distinct improvement effect on yield, rather than on the quality of grain. As one way of maximising maize productivity, soil health, and the overall functioning of crop agroecosystems, the integrated application of synergistic microbial and non-microbial biostimulants could provide a viable option. However, the ability to produce consistent yield and quality of grain improvement remains a major concern.
