The modern agricultural system has issues with the reduction of productivity due to a wide range abiotic and biotic stresses. It is also expected that in future entire world population may rapidly increase will surely demand more food. Farmers now utilize massive quantity synthetic fertilizers pesticides for disease management food production. These badly affect environment, texture soil, plant productivity, human health. However, safety sustainability depend on an ecofriendly inexpensive biological application. In contrast fertilizers, soil inoculation plant-growth-promoting rhizobacteria (PGPR) one excellent alternative options. this regard, we focused best PGPR genera, Pseudomonas, which exists rhizosphere as well inside plant's body plays role sustainable agriculture. Many Pseudomonas spp. control pathogens play effective through direct indirect mechanisms. fix amount atmospheric nitrogen, solubilize phosphorus potassium, produce phytohormones, lytic enzymes, volatile organic compounds, antibiotics, secondary metabolites during stress conditions. compounds stimulate growth by inducing systemic resistance inhibiting pathogens. Furthermore, pseudomonads protect plants different conditions like heavy metal pollution, osmosis, temperature, oxidative stress, etc. Now, several Pseudomonas-based commercial products have been promoted marketed, but there are few limitations hinder development technology extensive usage systems. variability among members draws attention huge research interest genus. There need explore potential native biocontrol agents use them biopesticide support

Abstract Drought stress is a worldwide threat to the productivity of crops, especially in arid and semi-arid zones world. In present study, effect selenium (Se) seed priming on yield quinoa under normal drought conditions was investigated. A pot trial executed enhance tolerance by Se (0, 3, 6, 9 mg L −1 ). The plants were exposed water at three different growth stages quinoa, viz. multiple leaf, flowering, filling. It noticed that significantly affected components however, improved potential maintaining plant status. increased main panicle length (20.29%), weight (26.43%), thousand grain (15.41%) as well gas exchange parameters (transpiration rate (29.74%), stomatal conductance (35.29%), photosynthetic (28.79%), total phenolics (29.36%), leaf chlorophyll contents (35.97%), relations (leaf relative (14.55%), osmotic (10.32%), (38.35%), turgor (31.37%), economic (35.99%) stress.

Drought stress as a result of rapidly changing climatic conditions has direct negative impact on crop production especially wheat which is the 2nd staple food crop. To fulfill nutritional demand under declining water resources, there dire need to adopt precise, and efficient approach in form different amendments. In this regard, present study investigated nano-biochar (NBC) brassinosteroids (BR) enhancing growth productivity drought conditions. The field comprised combinations amendments (control, NBC, BR, NBC + BR) three irrigation levels (D0, D1 D2). Among treatments, synergistic (NBC resulted maximum increase yield parameters normal well With BR), plant height (71.7 cm), spike length (17.1), number fertile tillers m-2 (410), no. spikelets spike-1 (19.1), grains (37.9), 1000 grain weight (37 g), (4079 kg ha-1), biological (10,502 harvest index (43.5). case physiological such leaf area index, relative contents, chlorophyll stomatal conductance were maximally improved with combined application BR. same treatment caused an 54, 10, 7% N, P, K contents grains, respectively compared control treatment.

Sustainable agriculture is threatened by salinity stress because of the low yield quality and crop production. Rhizobacteria that promote plant growth modify physiological molecular pathways to support development reduce abiotic stresses. The recent study aimed assess tolerance capacity impacts Bacillus sp.

In comparison uninoculated plants, inoculation improved agro-morphological traits [shoot length (6%), root (22%), height (16%), fresh weight (39%), dry (29%), leaf area (11%)], chlorophyll [Chl a (17%), Chl b (37%), total chl (22%)], carotenoids (15%), proteins (40%), sugars (43%), relative water (11%), flavonoids phenols (23%), radical scavenging (13%), antioxidants. PM31-inoculated plants showed reduction in oxidative indicators [electrolyte leakage (12%), H2O2 (9%), MDA (32%)] as compared under increased level osmolytes [free amino acids (36%), glycine betaine proline (11%)]. enhancement was further validated profiling PM31. Moreover, these mechanisms were accompanied upregulation stress-related genes (APX SOD).
