“…Small amounts of phytohormones like auxins that are present in the seaweed extracts and numerous stimulatory mechanisms that are activated in the plant system as a result of treatment with these extracts may explain the better rooting architecture ( Ali et al., 2021b ). Besides the presence of hormones, the seaweed extracts in the present study also contained polyphenols and flavonoids which also has known positive effect on plants ( Vaghela et al., 2022 ). One of the constituents of the present formulation used is an extract from the seaweed Kappaphycus alvarezii , which has been found to modulate a number of genes and transcription factors towards favourably increasing biomass and yield in maize upon foliar application or drenching ( Kumar et al., 2020a ; Trivedi et al., 2021b ).…”

“…Seaweed extract based biostimulants also contain quaternary ammonium compounds ( Trivedi et al., 2018 ) and several other metabolites ( Vaghela et al., 2022 ) which have been found to be associated with several plant physiological processes including that of tolerance to drought stress. Seaweed extracts have been reported to cause alterations in the physiological/biochemical processes involved in nutrient intake and plant development such as early seed germination and establishment ( Calvo et al., 2014 ), accelerated root growth, increased leaf chlorophyll ( Jannin et al., 2013 ; Kumar et al., 2020a ), better production and greater tolerance to environmental stress ( Yao et al., 2020 ).…”

The usage of seaweed extracts in cropping systems is gaining attention nowadays due to their distinct bioactive properties. This study aims to assess how saffron (Crocus sativus L.) corm production was affected by seaweed extract through different application modes. The study was conducted at the CSIR-Institute of Himalayan Bioresource Technology, Palampur, HP, India, during the autumn-winter agricultural cycle. Five treatments using a combination of Kappaphycus and Sargassum seaweed extracts were replicated five times in a randomized block design. Treatments that were examined include T1: Control, T2: Corm dipping @ 5% seaweed extract, T3: Foliar spray @ 5% seaweed extract, T4: Drenching @ 5% seaweed extract, and T5: Corm dipping + foliar spray @ 5% seaweed extract. Seaweed extract, when applied to saffron plants (T5: Corm dipping + foliar spray @ 5% seaweed extract) resulted in significantly higher growth parameters along with the higher dry weight of stem, leaves, corms, and total roots per corm. Corm production, viz., the number of daughter corms and corm weight per m2 was significantly affected by seaweed extract application, with the maximum value recorded with treatment T5. Biochemical parameters chlorophyll, carotenoids, and photosynthetic rate were higher in T5, while nutrient concentration was lowest in this treatment. Seaweed extracts improved corm production, making it a feasible alternative to limiting the application of conventional fertilizers, attenuating the effects on the environment, and enhancing corm number and weight.

“…Through genome sequencing, we can discover changes or mutations in gene sequences and their regulatory elements that may arise due to stress responses. Vaghela et al (2022) attempted to characterize and execute metabolomics profiling of Kappaphycus alvarezii SWE and comprehend its linkage with recognized bioactivities. From the above study, kinetin, dodecanamide, 1-phosphatidyl-1Dmyoinositol, sulfabenzamide, and several other compounds have prominent bioactivities like plant growth promotion, photo-protection, hormone signaling, disease resistance, antimicrobial, antioxidant and anti-herbivory properties.…”

Role of biostimulants in mitigating the effects of climate change on crop performance

et al. 2022

Climate change is a critical yield–limiting factor that has threatened the entire global crop production system in the present scenario. The use of biostimulants in agriculture has shown tremendous potential in combating climate change–induced stresses such as drought, salinity, temperature stress, etc. Biostimulants are organic compounds, microbes, or amalgamation of both that could regulate plant growth behavior through molecular alteration and physiological, biochemical, and anatomical modulations. Their nature is diverse due to the varying composition of bioactive compounds, and they function through various modes of action. To generate a successful biostimulatory action on crops under different parameters, a multi–omics approach would be beneficial to identify or predict its outcome comprehensively. The ‘omics’ approach has greatly helped us to understand the mode of action of biostimulants on plants at cellular levels. Biostimulants acting as a messenger in signal transduction resembling phytohormones and other chemical compounds and their cross–talk in various abiotic stresses help us design future crop management under changing climate, thus, sustaining food security with finite natural resources. This review article elucidates the strategic potential and prospects of biostimulants in mitigating the adverse impacts of harsh environmental conditions on plants.

“…Additionally, the seaweed extracts possess macro and micronutrients including some PGRs such as IAA, CK, abscisic acid, amino acids, and vitamins which can improve plant growth, soil microecology, and fertilizer use efficiency indicating it as a potential fertilizer/biostimulant ( Jung and Kim, 2020 ). Besides these, a recent study claimed that the presence of some secondary metabolites in seaweed extracts like sulfabenzamide, 1-phosphatidyl-1D-myoinositol, and dodecanamide has proven bioactivities related to plant growth promotion and disease resilience ( Vaghela et al., 2022 ). Also, the presence of quaternary ammonium compounds like glycine, betaine, and choline chloride in seaweed extracts may impart resilience to crops against various stressors, especially under rainfed conditions because of their osmolytic properties ( Singh et al., 2016b ).…”

Cleaner production technologies for the amelioration of soil health, biomass and secondary metabolites in Ocimum basilicum L. under Indian Western Himalaya

et al. 2022

Ocimum basilicum L. and its derived products are primarily consumed by humans; hence, agrochemical use seems inappropriate for its cultivation. However, farmers are accustomed to using rampant inorganic fertilizers to augment crop productivity, which has unintendedly engendered severe environmental perturbations. Concomitantly, farmers will soon have to confront the challenges of growing crops under suboptimal conditions driven by global climate change. Consequently, to develop a clean, sustainable, and resilient production technology, field experiments spanning over two years (2020 and 2021) were conducted, comprising three biostimulants, viz., vermicompost (0, 4, and 8 Mg ha−1), biofertilizer (uninoculated and inoculated), and liquid seaweed extract (without and at 7 ml L−1) in the Indian western Himalaya for the first time. Soil health indicators, leaf photosynthetic pigments, gaseous exchange, mineral contents, essential oil (EO) quantity, and composition were evaluated. Soil microbial respiration (SMR), microbial biomass carbon (MBC), organic carbon (OC), dehydrogenase (DHA), alkaline phosphatase (ALP), and β-glucosidase activities were increased by 36.23, 83.98, 30.61, 42.69, 34.00, and 40.57%, respectively, when compared with the initial soil status. The net photosynthetic rate (Pn) was significantly increased with the highest (8 Mg ha−1) and moderate (4 Mg ha−1) vermicompost dosages by 13.96% and 4.56%, respectively, as compared with the unfertilized control (0 Mg ha−1). Likewise, the biofertilizer and seaweed extract also enhanced Pn by 15.09% and 10.09%, respectively. The crop’s key EO constituents, viz., methyl chavicol and linalool, were significantly improved with the highest and moderate vermicompost rates of 2.71, 9.85%, and 1.18, 5.03%, respectively. Similarly, biofertilization and seaweed application also boosted methyl chavicol and linalool by 3.29, 8.67%, and 1.93, 3.66%, respectively. In both years, significantly higher herbage (8.86 and 11.25 Mg ha−1) and EO yield (113.78 and 154.87 kg ha−1) were recorded with a congregate treatment of the highest vermicompost dose, biofertilizer, and liquid seaweed extract. In conclusion, the integrated use of biostimulants having complementary properties can sustainably maximize the quantity and quality of O. basilicum and concomitantly ameliorate soil health. This study can inspire scientific communities and industries to develop second-generation biostimulant products, delivering better sustainability and resilience for a renaissance in agriculture.
