Indian economy is largely influenced by agriculture.The present work focuses on evaluation of Plant Growth Promoters (PGPs) and fungicides based products in plant growth and protection. Lab-scale experimental studies were conducted at Green Vision Life Sciences Pvt. Ltd., Pune, India during January to March 2018 to estimate germination rate (by defining physico-chemical parameters like water pH, seed quality, seed conductivity, hollow heart disease test, blotting test for germination, viability, Root growth (ANOVA analysis) andplant growth by using different application methodslike drenching, root dipping and spraying. The degree of rooting and shooting were found to be associated with the applied PGPS type and concentration. Further the project envisages a comparative analysis of agricultural products containing PGPs, where ABI4- 0.1% and ABI4 NEW-0.1% (products with higher concentration of PGPs) showing 100% germination when compared with non-treated plant(control) for plant height, No. of leaves, rootgrowthand grain weight, conductivity test, hollow heart test to calculate EEF(Expected Emergence Field). Results of this study indicates that the PGPS and fungicides either commercially available (procured from market) or lab prepared widens the commercial prospects of PGPSin more concentrationsfor increasing the agricultural productivity of otherdicot plants thereby increasing the agricultural sector’s input to India’s GDP through sustainable agriculture methods(promoting biodiversity, minimizing loss of resources).

<p class="1Body">Free-living diazotrophs play an important role as plant growth promoters by supplementing nitrogen to deficient soils. In this study, six diazotrophic isolates were selected from 36 previously screened diazotrophic isolates for their mode of action to promote plant growth. A nitrogen free medium was used to screen nitrogen fixing diazotrophs. All strains have exhibited some activity of indole-3-acetic acid production. Strain MAF7-1 shown the highest (0.448 mg ml<sup>-1</sup>), while strain NUL3-2 exhibited the least (0.032 mg ml<sup>-1</sup>) production of IAA. Though all isolates were unable to solubilize inorganic phosphate, were able to inhibit the growth of <em>Fusarium oxysporum</em> that causes wilting to plants. There was no significant difference in maize seed germination vigour and rate. However, MAF7-1 had better germination rate and seed vigour (27.5%) when compared to the control (16%). Except strain NUL3-2, all showed significant increase of root length and dry weight of maize seedlings. Therefore, the choice of strain to be used for production of biofertilizer should not only be based on the nitrogenase activity, but also on ability to produce phytohormones.  Strain NUL3-2, MAF7-1 and MAF7-3 are potential strains that can be used in the production of biofertilizer. Further study of these strains in depth as plant growth agents and biofertilizer is commendable for future application.</p>

Plant Growth Promoters

Recently, there have been many exciting new developments relating to the use of Trichoderma spp. as agents for biocontrol of pathogens and as plant growth promoters. Several mechanisms have been proposed to explain the positive effects of these microorganisms on the plant host. One factor that contributes to their beneficial biological activities is related to the wide variety of metabolites that they produce. These metabolites have been found not only to directly inhibit the growth and pathogenic activities of the parasites, but also to increase disease resistance by triggering the system of defence in the plant host. In addition, these metabolites are also capable of enhancing plant growth, which enables the plant to counteract the disease with compensatory vegetative growth by the augmented production of root and shoot systems. This review takes into account the Trichoderma secondary metabolites that affect plant metabolism and that may play an important role in the complex interactions of this biocontrol agent with the plant and pathogens.
