“…It has been reported that significant differences in chlorophyll pigment content occur in plants exposed to drought stress (Güzel, 2006). The decrease in chlorophyll content in plants under drought stress may be due to the degradation of chlorophyll (Christ et al, 2014) or changes in enzymatic activities involved in chlorophyll synthesis that slow or inhibit chlorophyll synthesis (Cotrina Cabello et al, 2023). In our study, drought stress caused a 15.2% decrease in leaf chlorophyll content compared to the control.…”

Drought stress, one of the most important abiotic stresses, severely limits global crop production. To increase tolerance to this stress, environmentally friendly practices are emphasised. Humic acid, one of the most important natural biostimulants, has positive effects on plant growth and yield. Recently, it has also been reported to play an important role in resistance to various abiotic stresses. However, many physiological and molecular mechanisms by which humic acid confers drought resistance have not been fully elucidated. Therefore, the effects of humic acid application on different morphological and physiological stress indicators and some antioxidative enzyme gene expressions of tomato seedlings under drought stress conditions were investigated in this study. It was found that drought stress decreased shoot fresh/dry weight, root fresh/dry weight, shoot and root length, chlorophyll and relative water content of plants by 67%, 56%, 31%, 38%, 22%, 20%, 15% and 25%, respectively. Humic acid application significantly increased these parameters, while reducing ion leakage, MDA and proline levels. The antioxidant enzyme gene expression of tomato seedlings under drought conditions showed no significant difference in SOD and APX gene expression, whereas CAT gene expression increased and GR gene expression decreased with humic acid application. Our results showed that humic acid application interacted with stress-related antioxidant enzyme gene expression and may be effective in reducing drought stress.

“…Similarly, other physiological parameters such as YII, ETR, PSR and Ft were also improved considerably. Improvement in intracellular enzymatic activities due to biostimulants and composting increase the uptake of essential nutrients leading towards the enhancement of chlorophyll production (Hamid et al, 2021;Cotrina Cabello et al, 2023;Younas et al, 2022;Gondal et al, 2023a). Chemical factors like organic carbon, organic matter, N, K, Zn, and P all got better when cytokinin and composting were used as a treatment.…”

Integrated nutrient management is a promising way to avoid plant nutrient shortages because of the positive relationship between the bioavailability of nutrients and greater economic interest in their application through organic amendments and microbial application. To examine how compost, charcoal, and rhizobium influence maize development, an experiment was set up in a container. In addition to the appropriate amounts of nitrogen, phosphorous, and potassium, the soil in the allotted pots was treated with 50 ml of rhizobium, 5 tonnes of compost, and 2.5 tonnes of biochar before maize seeds were planted. A total of nine treatments (with three replicates each) were arranged in a completely randomized design for this experiment. Various agronomic, chemical, and physiological data were measured and recorded after the crop was harvested 110 days after sowing. The results showed that when biochar, compost, and rhizobium were applied together, the root fresh biomass rose by 43.4%, the root dry biomass increased by 38.3%, and the shoot length increased by 61.7%, compared to the control treatment. Chlorophyll content (41.3% higher), photosynthetic rate (58.5% higher), transpiration rate (64.4% higher), quantum yield (32.6% higher), and stomatal conductivity (25.3% higher) were all significantly improved compared to the control. Soil levels of nitrogen, phosphorus, and potassium were also improved with this treatment compared to the control. The combined use of biochar, compost, and rhizobium was more successful than any of the components used individually in boosting maize yields. Based on the findings of our study, the integration of rhizobium, biochar, and compost within a unified treatment shown a substantial enhancement in both the growth and yield of maize.

“…Priming, achieved through pre-exposure of plants to an elicitor or mild stress, induces a stress memory in plants and prepares them to be more effective in responding to subsequent stress events (Yuan, et al 2023). Priming is a promising strategy to enhance crop tolerance to different abiotic and biotic stress under climate change (Awaad and Awaad 2022;Cotrina Cabello, et al 2023). ABA has been for priming for enhanced drought tolerance in different plant species including Arabidopsis, pepper, tomato, apple, crab apple, and olive trees (Ban, et al 2017;Jakab, et al 2005 Small RNAs (sRNAs) are short non-coding RNAs with a length ranging between 20 and 24 nucleotides.…”

Previously we showed that a single exogenous application of Abscisic acid (ABA) on Arabidopsis in early developmental stages results in enhanced plant biomass and drought tolerance in the adult plants. Here we tested the hypothesis that small RNAs (sRNAs), including micro RNAs (miRNAs) and small interfering RNAs (siRNAs), contribute to the observed ABA effects. We sequenced sRNA populations in Arabidopsis plants that were sprayed with ABA or water at the cotyledonary stage at two time-points, 4 hours and 14 days after spraying. Analyses of the sRNAs revealed that at 4 hours, four miRNA families, miR408, miR398, miR397, and miR393, were significantly down-regulated by the ABA application. These miRNAs are all copper-induced miRNAs, which are known to be involved in the regulation of antioxidant enzymes and lignification metabolic pathways. After 14 days, miR395 and miR169 families were up-regulated, while miR399 and miR827 families were down-regulated in ABA-treated plants. These miRNAs are mostly characterized as regulators of macronutrient uptake. We identified 77 and 30 differentially expressed siRNA loci in the first and second time-points respectively. Interestingly, a majority of these ABA-responsive siRNAs were found to be mainly associated with the non-coding regions of the genome, as well as with genes related to photosynthesis, particularly those encoding light-harvesting complex proteins. In summary, our data suggest that ABA-responsive miRNAs contribute to the positive effects of ABA by increasing plant antioxidant capacity and lignification in the short-term while increasing nutrient uptake in the long term.
