“…This corroborates with findings of Guler et al [10] in maize. Similarly, application of B. subtilis reduced catalase activity which is similar to the findings of Saad and Abo-Koura [11] in sorghum and Vardharajula et al [12] in maize.…”

Water-deficit stress is an important concern worldwide that reduces crop yield and quality. Mustard is an important oilseed crop of India which is adversely affected by water-deficit stress in terms of growth and yield. Tolerance to water-deficit stress is correlated with the redox regulatory and antioxidant system. To mitigate negative effect of water-deficit stress, field experiment was conducted at Dholi (Muzaffarpur), Bihar during 2019-20 with an aim to study the effect of microbes on antioxidant systems in mustard grown under water-deficit stress vis-à-vis normal irrigated conditions. Pre-screened contrasting genotypes (tolerant ‘NPJ 214’ and sensitive ‘TM 179’) were sown in the experimental farm using factorial experiment in randomized block design with three replications. The treatments (12) comprised of two factors viz., genotypes (2) and microbial inoculants along with control (3) sown under normal ‘irrigated’ and ‘water-deficit stress’ conditions. Soil inoculation microbes Bacillus subtilis and Trichoderma viride was done 35 days after sowing and was compared with non-inoculated control. Results revealed that the activity of antioxidative enzymes viz., catalase and peroxidase increased under water-deficit stress; the increase was reduced by the application of B. subtilis and T. viride in both tolerant and sensitive genotypes, and more pronounced in the sensitive genotypes. Similar results were recorded with respect to lipid peroxidation and proline content. Increase in concentration of stress-induced metabolites was less in colonized plants of mustard indicating modulation of antioxidant system. The maximum ameliorating effect was observed with application of T. viride which could be an important tool in alleviating the adverse effects of water-deficit stress in mustard.

“…Drought and salinity are the major abiotic stresses that affect crop production especially in sandy soils. Drought is a major constraint to agricultural production which clearly decreases with increasing soil moisture stress (Samson et al 2002;Saad and Abo-Koura (2018) and El-Kallawy and Hefeina, 2019). Deficit irrigation greatly reduced 1000-grain weight (Emam et al 2007), growth and grain yield of wheat (Moghaddam et al 2012), plant height and grain yield of wheat (Akbar et al 2010 andAiad, 2019), while the maximum wheat yield was achieved by 84% of full evapotranspiration (Zhang et al 2008).…”

T HE DROUGHT is one of the most important abiotic stresses limiting the crop productivity especially in sandy soils in arid and semi-arid areas. So, using soil amendments such as vermicompost (VC), biochar (BC), and polymer (PL) are more important in these areas. Lysimeter experiments with sandy soil were carried out at Sakha Agric. Res. Station, Kafr El-Sheikh, Egypt to study the effect of 0.4% PL, 4.0% VC and 1.0% BC (W:W soil) on productivity of wheat (2018/019) and maize (2019) under two irrigation levels (irrigation after depletion of 50% and 75% from soil moisture. The obtained results indicated that irrigation at 75% moisture depletion (irrigation deficit) decreased plant height, 100-grain weight, grain and straw yields, water applied to wheat (-16.8%) and maize (-20%) compared to that with higher irrigation level (50% depletion). Also, water productivity was slightly decreased for wheat, but it slightly increased for maize and ECe values were slightly increased due to irrigation deficit. Also, applications of soil amendments and their combinations significantly increased plant height, 100-grain weight, yield and water productivity of both crops and improved soil porosity and field capacity. The VC was more effective treatment followed by BC and PL treatments, while their interactions were the most effective on these parameters. Moreover, soil amendments alleviated the deleterious effects of irrigation deficit on plant growth and salt accumulation. Finally, applying BC combined with VC and PL could be recommended as a good approach to maintain long-term productivity of sandy soils and mitigate the hazardous effects of drought stresses.

“…The drought tolerance by the isolate was determined according to Saad and Abo-Koura ( 2018 ). The isolate was grown in nutrient broth supplemented with different concentrations of polyethylene glycol 6000 i.e., 0, 10, 20 and 30% at 37 °C with shaking (150 rpm) for 72 h. Then, the optical density was measured by spectrophotometer at 600 nm.…”

Drought severity and duration are expected to increase as a result of ongoing global climate change. Therefore, finding solutions to help plants to deal with drought stress and to improve growth in the face of limited water resources is critical. In this study, a drought tolerant- plant growth promoting endophytic bacterium was isolated from Aloe vera roots. It was identified as Sphingobacterium changzhouense based on 16S rRNA gene sequencing and was deposited into NCBI database with accession number (ON944028). The effect of S. changzhouense inoculation on maize growth under drought stress was investigated. The results revealed that inoculation significantly (p ≤ 0.05) enhanced root and shoot elongation by 205 and 176.19% respectively. Photosynthesis rate, stomatal conductance and water use efficiency were improved in inoculated plants. interestingly, inoculation resulted in significant increase in total chlorophyll, total carbohydrates, proline, total proteins, total phenolics and total flavonoids by 64, 31.5, 25.1, 75.07, 83.7 and 65.4% respectively. Total antioxidant capacity of inoculated plants (51.2 mg/g FW) was higher than that of non-inoculated plants (11.87 mg/g FW), which was found to be positively correlated to the levels of phenolics and flavonoids. Our finding suggests that S. changzhouense could be used to improve crop growth and assist plants to resist drought stress in arid agricultural lands.
