“…However, indiscriminate use of agrochemicals has long lasting consequences on the environment, with some even being prohibited from further use, making agriculture one of the main sources of nonpoint pollution [2]. As the scientific community calls for more sustainability and environmentally friendly systems in agricultural practices, research on natural resources as alternatives to traditional chemical methods, such as plant biostimulants extracts, has been increasing in recent years [3].…”

As the world develops and population increases, so too does the demand for higher agricultural output with lower resources. Plant biostimulants appear to be one of the more prominent sustainable solutions, given their natural origin and their potential to substitute conventional methods in agriculture. Classified based on their source rather than constitution, biostimulants such as humic substances (HS), protein hydrolysates (PHs), seaweed extracts (SWE) and microorganisms have a proven potential in improving plant growth, increasing crop production and quality, as well as ameliorating stress effects. However, the multi-molecular nature and varying composition of commercially available biostimulants presents challenges when attempting to elucidate their underlying mechanisms. While most research has focused on the broad effects of biostimulants in crops, recent studies at the molecular level have started to unravel the pathways triggered by certain products at the cellular and gene level. Understanding the molecular influences involved could lead to further refinement of these treatments. This review comprises the most recent findings regarding the use of biostimulants in plants, with particular focus on reports of their molecular influence.

“…The traditional approach to raise soil productivity is through amending soils with synthetic fertilizers (Verma et al, 2020); however, in light textured ones, considerable losses of the applied nutrients may occur through water leachate (elshony et al, 2018). Moreover, the prices of synthetics fertilizers are growing up continuously (Rouhollahi et al, 2020) and this may threaten the sustainability of growing plants in egypt.…”

“…Accordingly, substituting chemical synthetic fertilizers partially with slow-releaseorganic fertilizers should come to light to sustain development (el-Akhdar et al, 2018 andTang et al 2019). Such a"Green Revolution" may change the country category from food importer to selfsufficient (Verma et al, 2020).…”

A fIelD experiment was conducted at the experimental farm of Soil and Water Research Department, Nuclear Research Centre, Atomic energy Authority, Inshas, egypt to investigate the effects of radiating canola seeds with γ-ray at three doses, i.e. 100, 200 and 300 Gy vs the non-irradiated controlon plant growth performance and yield productivity. Nitrogen fertilization and the source of irrigation water were also matters of concern in this study. All experimental plots received the recommended dose of N-fertilizers (150 kg N ha-1) in either of the following forms:100% mineral-N, 100% organic-N or 50% mineral-N +50% organic-N. Also, a drip irrigation-system was constructed to irrigate canola plants with either freshwater or treated-wastewater. Irradiation, in general, resulted in higher values of canola-dry-weights which were enhanced by increasing gamma ray dose up to 300Gy. Similarly, NPK contents within different plant parts of the irradiated-canola increased in an order coincide with the magnitudes of the used irradiation dose, i.e. 300Gy> 200Gy >100Gy > 0Gy. Moreover, oil yield was significantly increased with increasing gamma dose. On the other hand, the enhancement of NPK uptake was more vigorous in case of combined-fertilization-treatment (50% mineral-N +50% organic-N) than the application of either 100% mineral-N or 100% organic-N. This consequently raised significantly root and shoot dry weights as well as seed yield and canola oil productivity. It seems that irrigation with treated wastewater resulted in higher increases in NPK uptake as well as canola oil yield than irrigation with freshwater. Thus, it can be deduced that the combined-fertilization-treatment and high irradiation dose of gamma-ray had achieved the highest increases in plant DW and productivity (5.3 Mg seed yield ha-1), at the same time these values were higher under irrigation with treated wastewater than those irrigated with fresh water.

“…According to Jaramillo et al (2007), greenhouse cultivation is included within the protected techniques that promote favorable and optimal artif icial or microclimate conditions (as incidental radiation, precipitation, temperature, and humidity) with calidad deseable en las cosechas. En cuanto al uso de fertilizantes químicos y sus altos costos económicos y ecológicos se ref iere, son aspectos que sin duda han provocado la búsqueda de alternativas y nuevas estrategias de manejo que reduzcan el uso y aplicación de insumos contaminantes para las plantas, ser humano, agua, suelo y ambiente (Yuan et al, 2017;Verma et al, 2020). Ante la fertilización de las plantas con productos químicos, el uso de bacterias promotoras del crecimiento vegetal (BPCV) y la aplicación de abonos orgánicos como la lombricomposta, se convierten en una opción para desarrollar sistemas agro-productivos donde la aplicación de fertilizantes químicos se reduzca y se fomente una producción sostenible (Brar et al, 2019;Parastesh et al, 2019).…”

“…the purpose of guaranteeing a desirable quality and production at harvest. With respect to the use of chemical fertilizers and their high economic and ecological costs, they are undoubtedly aspects that have caused the search for alternatives and new management strategies, which may reduce the application and use of contaminant supplies for plants, humans, water, soil, and the environment (Yuan et al, 2017;Verma et al, 2020). Faced with the use of chemical fertilization products on plants, growth promoting bacteria (PGPB) and the application of organic manure, such as vermicompost, have turned out to be options for the development of productive farming systems that promote reducing the use of chemical fertilizer and favoring sustainable production (Brar et al, 2019;Parastesh et al, 2019).…”

El uso de agroquímicos en el cultivo de chile dulce ha originado la búsqueda de alternativas de fertilización como Bacillus subtilis y lombricomposta, los cuales, son una opción para producir alimentos sin afectar al ambiente, salud humana y animal. El objetivo de este estudio fue evaluar el efecto de la incorporación individual y en conjunto de B. subtilis y lombricomposta sobre la respuesta agronómica de chile dulce bajo invernadero. Se utilizó un diseño completamente al azar con 15 repeticiones por cada tratamiento donde; T1 = plantas con fertilizante químico; T2 = B. subtilis; T3 = B. subtilis + fertilizante químico; T4, T5 y T6 = 280, 380 y 570 g de lombricomposta, respectivamente; T7, T8 y T9 = B. subtilis + 280, 380 y 570 g de lombricomposta, respectivamente. A los 90 días después de la siembra se evaluó: altura, diámetro del tallo, número de hojas, número de botones, número de flores, área foliar, producción de fruto y población bacteriana (UFC). Las plantas de chile dulce con la dosis más alta de lombricomposta (570 g) más B. subtilis presentaron los mayores incrementos en todas las variables evaluadas superando signif icativamente a las plantas con fertilizante químico. La aplicación en conjunto de lombricomposta y B. subtilis puede ser una alternativa para la producción de chile dulce sin tener que emplear fertilizantes químicos.
