Abstract Moringa oleifera Lam . is a common edible plant, famous for several nutritional and therapeutic benefits. This study investigates the salt -induced modulations in plant growth, physio-biochemical responses, antioxidant performance of M. grown under 0, 50, 100 mM NaCl concentrations. Results showed that effectively managed moderate salinity (50 NaCl) by maintaining succulence, weight ratios, biomass allocation patterns both shoot root with minimal reduction dry biomass. However, high (100 remarkably declined all growth parameters. The accumulated more Na + Cl − , while less K as compared to control. Consequently, osmotic potentials leaf decreased salinity, which was corroborated amount proline soluble sugars. Increased level H 2 O significantly unchanged membrane fluidity indicating its role perceiving managing stress at salinity. In addition, increased activities superoxide dismutase, catalase, glutathione flavonoid contents suggest an integrated participation enzymatic non-enzymatic components regulating ROS. On other hand, caused outburst ROS indicated MDA, electrolyte leakage. As response, moringa drastically enzymes molecules including ascorbic acid, glutathione, total phenols, flavonoids radical scavenging reducing power capacities. considerable energy used such management resulting significant NaCl. suggests resisted modulating attributes ion toxicity oxidative stress. Salt also enhanced medicinal increasing compounds their activities. It can be on degraded/ saline lands this purposes, besides providing benefits global climate change scenario.

Biochar (BC) properties and its influences within agricultural soil health environmental ecosystems largely depend on feedstock, residence time pyrolysis conditions. The organic inorganic contaminants from can be removed using BC as an adsorbent. Additionally, amendment with is known to improve overall quality, microbial enzymatic activities carbon content nutrient retention availability. Moreover, one of the great impacts capability capture nutrients sequestrate carbon. physicochemical biochar could affected by feedstocks conditions (temperature, duration, activation method, etc.). This review paper summarizes recent research studies composition that controls presence in soil, well BCs role improving fertility sequestration, which has not been reported detail yet. main finding present work revealed high pyrolytic temperatures production may have negative phyto-availability essential nutrients. Depending feedstock raw material process used for producing BC, it different capacities releasing soil. An economically feasible method newly engineered biochar, more controlled C-based materials, suitable agriculture needs developed. Further investigation should carried out optimize procedure application local farming community sustainable agriculture.

Biochemical Response of Okra (Abelmoschus esculentus L.) to Selenium (Se) under Drought Stress

Sustainability, Год журнала: 2023, Номер 15(7), С. 5694 - 5694

Опубликована: Март 24, 2023

Drought stress restricts the growth of okra (Abelmoschus esculentus L.) by disrupting its biochemical and physiological functions. The current study was conducted to evaluate role selenium (0, 1, 2, 3 mg Se L−1 as a foliar application) in improving tolerance drought (control (100% field capacity-FC), mild (70% FC), severe (35% FC)) imposed 30 days after sowing (DAS). (severe) markedly decreased chlorophyll (32.21%) carotenoid (39.6%) contents but increased anthocyanin (40%), proline (46.8%), peroxidase (POD 12.5%), ascorbate (APX 11.9%), catalase (CAT 14%) activities. Overall, application significantly alleviated stress-related disturbances okra. Mainly, (21%) well (15.14%), (18.16%), antioxidant activities both under control conditions. Selenium played beneficial reducing damage caused oxidative stress, enhancing antioxidants contents, improved plant stress. Therefore, crops including especially, must be supplemented with for obtaining optimum yield arid semiarid drought-affected areas.

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. Similarly, antioxidant response was enhanced plants conclusion, BR significant growth, attributes stress.

ACS Omega, Год журнала: 2023, Номер 8(23), С. 20471 - 20487

Опубликована: Май 26, 2023

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. PM31 on growth, physiological, responses maize stress. 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). Our found has crucial substantial role reducing through processes, which may be used an alternative approach boost production yield.

Agricultural production is severely limited by an iron deficiency. Alkaline soils increase deficiency in rice crops, consequently leading to nutrient deficiencies humans. Adding enhances both its elemental composition and the nutritional value it offers humans through food chain. The purpose of current pot experiment was investigate impact Fe treatment alkaline (pH 7.5) acidic 5.5) introduce iron-rich rice. Iron applied plants soil form aqueous solution FeSO4 with five different concentrations (100, 200, 300, 400, 500 mM). results obtained from study demonstrated a significant content Oryza sativa application pH soils. Specifically, Basmati-515, one cultivars tested, exhibited notable 13% total accumulation per plant 11% root-to-shoot ratio soil. In contrast Basmati-198, which maximum response soil, Basmati-515 increases all parameters, including 31% dry weight, 16% chlorophyll content, CAT (catalase) activity, 7% APX (ascorbate peroxidase) 26% POD (peroxidase) remarkable 92% SOD (superoxide dismutase) Basmati-198 respective decreases 40% 39% MDA H2O2 whereas more decrease 50% 67% These emphasize potential for targeted management strategies improve nutrition address agricultural systems. By considering conditions, possible enhance promote availability soils, ultimately contributing improved crop human health.
