Published: Jan. 1, 2025

Abiotic stresses such as drought, heat, salinity, and heavy metal contamination severely affect global agricultural productivity.Between 2005 2015, droughts caused losses of approximately USD 29 billion in developing countries, from 2008 to 2018, accounted for over 34% crop livestock yield losses, totaling about 37 billion.To support the growing human population, output must increase substantially, necessitating a 60%-100% rise productivity meet escalating demand.To address environmental challenges, organic, inorganic, microbial biostimulants are increasingly employed enhance plant resilience through various morphological, physiological, biochemical modifications.Plant under abiotic stress mechanisms abscisic acid signaling modulation, which regulates stomatal closure reduce water loss during drought heat stress.Additionally, they aid scavenging reactive oxygen species stabilizing ion channels, mitigating oxidative damage, maintaining ionic balance conditions salinity.This review summarizes recent advancements applying these biostimulants, focusing on their roles triggering biochemical, molecular changes that collectively conditions.It also includes bibliometric analysis all articles published 2019 2024 explores future research directions.Emphasis was placed optimizing biostimulant formulations understanding synergistic effects maximize efficacy conditions.By integrating into practices, we can adopt sustainable strategy safeguard face climate change stressors.

Foliar application of Verticillium dahliae Aspf2‐like protein improved the heat tolerance of creeping bentgrass by regulating photosynthetic and antioxidant capabilities

Crop Science, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 11, 2024

Abstract Continuous high ambient temperature in hot summer months leads to a sharp decline turf quality of cool‐season turfgrass. Verticillium dahliae Aspf2‐like protein (VDAL) is secretory V. that can improve crop yield and resistance disease, but its role improving heat tolerance turfgrass has not been reported so far. The objectives this study were explore the effect mechanism foliar application VDAL on creeping bentgrass ( Agrostis stolonifera ) further examine advantage spraying with mitigating (SBD) US transition zone or other regions similar climate. results demonstrated optimal dose for thermotolerance two cultivars (heat‐tolerant 13 M heat‐sensitive Seaside II) was screened as 0.2 g L −1 based analyses chlorophyll content, photochemical efficiency PSII, cell membrane stability under controlled stress conditions. Foliar significantly restricted loss also alleviated heat‐induced declines net photosynthetic rate, transpiration stomatal conductance, water use efficiency. In addition, overaccumulations superoxide anion radical hydrogen peroxide could be by exogenous through activity antioxidant enzymes including dismutase, peroxidase, catalase, ascorbate peroxidase cultivars. A 2‐year field trial showed improved quality, efficiency, during 2022 2023. indicate appropriate plays positive performance capacity bentgrass, considered an effective approach alleviating SBD.

Demonstrating Agroecological Practices in Potato Production with Conservation Tillage and Pseudomonas spp., Azotobacter spp., Bacillus spp. Bacterial Inoculants—Evidence from Hungary

Agronomy, Journal Year: 2024, Volume and Issue: 14(12), P. 2979 - 2979

Published: Dec. 14, 2024

This study explores agroecological practices designed to improve soil quality and crop yield in small-scale agriculture, focusing on inoculation with beneficial bacteria over conventional fertilizers. Conducted at the SZIA Agroecological Garden MATE Gödöllő, Hungary, research utilizes 12 plots evaluate different conservation tillage methods, including minimum no-tillage, without microbial inoculation. Commenced 2022, this centers potato cultivation (Solanum tuberosum L.) includes comprehensive chemical physical analyses of harvested potatoes, alongside continuous monitoring growth. Statistical analysis using One-way Anova R revealed p-values predominantly above 0.05, indicating no significant differences across most parameters, though variations plasticity pH (KCl) were noted. Results suggest that substantial treatmeent may require a longer observation period. Notably, exhibited higher harvest weights tuber sizes compared control plots. Additionally, trends interactions found between weed abundance, total harvest, plant height. The findings indicate benefits integrated practices, tillage, take time materialize, emphasizing necessity for extended observation. lays groundwork future studies, underscoring importance patience achieving improvements health through sustainable agricultural methods.
