“…(including T. harzianum and T. viride) are the most abundantly reported fungi, and has been widely used as a source of different commercial biostimulants and biofungicides (Mahanty et al, 2017). Sureshrao et al (2016) showed that rice seedlings treated with T. viride had more lateral roots and better seed germination compared to the control plants. Similar outputs were also recorded by Lalitha and Arunalakshmi (2012) in mustard crops.…”

Environmental stressors such as salinity, drought, high temperature, high rainfall, etc. have already demonstrated the negative impacts on plant growth and development and thereby limiting productivity of the crops. Therefore, in the time to come, more sustainable efforts are required in agricultural practices to ensure food production and security under such adverse environmental conditions. A most promising and eco-friendly way to achieve this goal would be to apply biostimulants to address the environmental concerns. Non-microbial biostimulants such as humic substances (HA), protein hydrolysate, plant-based products and seaweed extracts (SWE), etc. and/or microbial inoculants comprising of plant growth-promoting microbes such as arbuscular mycorrhizal fungi (AMF), fluorescent and non-fluorescent Pseudomonas, Trichoderma spp., Bacillus spp. etc. have tremendous potentiality to enhance plant growth, flowering, crop productivity, nutrient use efficiency (NUE) and translocation, as well as enhancing tolerance to a wide range of abiotic stresses by modifying physiological, biological and biochemical processes of the crop-plants. Similarly, application techniques and timing are also important to achieve the desired results. In this article we discussed the prospects of using seaweed, microbial, and plant-based biostimulants either individually or in combination for managing environmental stresses to achieve food security in a sustainable way. Particular attention was given to the modifications that take place in plant's physiology under adverse environmental conditions and how different biostimulants re-program the host's physiology to withstand such stresses. Additionally, we also discussed how application of biostimulants can overcome the issue of nutrient deficiency in agricultural lands and improve their use efficiency by crop plants.

Crop performance is seriously affected by high salt concentrations in soils. To develop more new seed pre-sowing treatment technologies it is crucial to improve the salt tolerance of seed germination. Here we isolated and identified the strain Bacillus sp. MGW9 and developed the seed biostimulant MGW9 (SB-MGW9) by the strain. Effect of seed biopriming with SB-MGW9 in maize (Zea mays L.) under saline condition were studied. The results showed that the Bacillus sp. MGW9 has the characteristics of salt tolerance, nitrogen fixation, phosphorus dissolution, indole-3-acetic acid production and the like. Seed biopriming with SB-MGW9 enhanced the performance of maize during seed germination under salinity stress to improve the germination energy, germination percentage, shoot/seedling length, primary root length, shoot/seedling fresh weight, shoot/seedling dry weight, root fresh weight and root dry weight. SB-MGW9 biopriming also alleviates the salinity damage to maize by improving relative water content, chlorophyll content, proline content, soluble sugar content, root activity, activities of superoxide dismutase, catalase, peroxidase and ascorbate peroxidase, decreasing the malondialdehyde content. Especially, the field seedling emergence of maize seeds in saline-alkali soil can be improved by SB-MGW9 biopriming. Therefore, maize seed biopriming with SB-MGW9 can be an effective approach to resist the inhibitory effects of salinity stress and promote seed germination and seedling growth.

“…For example, Trichoderma viride and T. harzianum improved the seed germination and vigour of radish (Mukhopadhyay and Pan 2012 ). Seed biopriming with T. viride enhanced root growth in rice (Sureshrao et al 2016 ). Seeds inoculated with Bacillus subtilis and Pseudomonas fluorescens produced a significantly increased in the fresh weight, dry weight, photosynthetic pigments, proline, total free amino acids and crude protein content in radish roots and leaves under salt stress (Mohamed and Gomaa 2012 ).…”
