D UE to global warming and climate change, drought is considered one of the major abiotic stressful conditions that causes numerous morphological, physiological, and biochemical changes that limit the plant growth and productivity. The enhancement of drought tolerance by the application of plant growth-promoting rhizobacteria has been progressively documented. Therefore, the present study was carried out to examine the potential role of Rhizobium leguminosarum biovar. Phaseoli in attenuating the adverse effects of water deficiency (80, and 60% of the estimated crop evapotranspiration) on growth, yield and quality and some biochemical and physiological parameters of green bean plants cv. Valentino. The experimental design was a randomized complete block design with three replications. The obtained results revealed that increasing water deficit severity resulted in decreases in plant growth characteristics, leaf nutrient content, SPAD readings, leaf relative water content (LRWC), leaf membrane stability index (LMSI) and yield components, as well as induced increments in proline content, catalase, peroxidase, and superoxide dismutase activities. However, application of Rhizobium leguminosarum considerably improved all growth and yield parameters and enhanced SPAD readings, RWC, MSI, proline content, and antioxidant enzyme activities. It could be concluded that Rhizobium leguminosarum inoculation could be used as a promising and sustainable strategy to cope with the adverse impacts of drought stress on green bean productivity in the forthcoming era of climate change.

T HE experiment was conducted to reduce the buildup of heavy metals in lettuce plants grown in contaminated soil. Lettuce plants cv. Nader were cultivated on polluted soil in black polyethylene bags with or without the addition of biochar, rice straw, Pseudomonas fluorescens bacterial inoculation, biochar + rice straw, biochar + P. fluorescens , rice straw + P. fluorescens , and biochar + rice straw + P. fluorescens , as well as unpolluted soil as a control. The experiments were conducted in the seasons of 2019 and 2020 at the Vegetable Farm of the Faculty of Agriculture, Ain Shams University, Shubra El Kheima, Qalyubia Governorate, Egypt. The experimental treatments were distributed in a completely randomized design with three replicates. The attained results indicated that cultivating lettuce in polluted soil had negative effects on plant growth compared to those cultivated in unpolluted soil. Application of the experimental treatments improved the vegetative growth parameters, including plant length, leaf area, fresh and dry head weight, fresh and dry root weight, and head diameter. The results also showed that lettuce plants grown in heavy metal-polluted soil had lower values of vegetative growth parameters than those grown in polluted soil treated with biochar, rice straw, or P. fluorescens , and the interaction between them. When compared to bacterial inoculation treatment, the application of biochar and/or rice straw on lettuce plants grown in heavy metal-contaminated soil enhanced growth and leaf nutrient contents, while heavy metal contents decreased. The findings demonstrated that heavy metal-contaminated soil treated with biochar alone or in combination with rice straw and/or bacterial inoculation were effective in reducing the content of heavy metals in plant leaves and attenuating the harmful effects of heavy metals on grown lettuce plants
本试验旨在减少在污染土壤中生长的生菜中重金属的积累。在受污染的土壤上，在添加或不添加生物炭、稻草、荧光假单胞菌细菌接种、生物炭+稻草、生物炭+P.fluorescens、稻草+P.fluoroscens和生物炭+水稻秸秆+P.fluoriscens的黑色聚乙烯袋中，以及未受污染的土壤中作为对照，培养了纳德莴苣。实验于2019年和2020年在埃及卡柳比亚省Shubra El Kheima的艾因沙姆斯大学农业学院蔬菜农场进行。实验处理以完全随机的设计进行分配，共有三个重复。结果表明，与未污染土壤相比，在污染土壤中种植生菜对植物生长有负面影响。试验处理的应用改善了营养生长参数，包括株长、叶面积、鲜干茎重、鲜干根重和茎粗。结果还表明，在重金属污染土壤中生长的莴苣植物的营养生长参数值低于在用生物炭、稻草或荧光假单胞菌处理的污染土壤中种植的莴苣植物，以及它们之间的相互作用。与细菌接种处理相比，在重金属污染土壤中生长的莴苣植株上施用生物炭和/或稻草可以提高生长和叶片养分含量，而重金属含量则降低。研究结果表明，单独使用生物炭或与稻草和/或细菌接种相结合处理重金属污染土壤，可以有效降低植物叶片中的重金属含量，减轻重金属对生长的生菜的有害影响

T HE present investigation has been carried out for two consecutive seasons (2020 and 2021) on ‘Early Sweet’ grapevines in the experimental farm located at El-Baramon station, Horticulture Research Institute, Mansoura, Dakahlia Governorate, Egypt in order to enhance the vegetative growth traits, nutritional status, yield, and cluster quality attributes by the applications of arbuscular mycorrhizal fungi, seaweed extract, and Nano-Zinc oxide particles individually or combined. The soil was inoculated with arbuscular mycorrhiza fungi at 250 g inoculum/vine once during winter agricultural management and foliar spray with seaweed extract at 1% and Nano-Zinc oxide particles at 50 ppm at three times: after the bud burst stage, at fruit set stage and two weeks after fruit set stage. The results demonstrated that the used applications either individually or combined among them had a significant effect on all conducted traits compared to the control in both seasons. Also, the combined applications were the most effective than the individual applications, especially the triple application (arbuscular mycorrhiza fungi + seaweed extract + Nano-Zinc oxide particles) which significantly improved the vegetative growth aspects, leaf content of mineral elements, the weight of pruning wood, and cane content of total carbohydrates, as well as increasing yield and enhancing the quality attributes of clusters and berries especially the percentage of shot berries and the compactness coefficient of clusters. Therefore, it is recommended to apply this application for ‘Early Sweet’ grapevines vineyards.

Experimental treatments were spraying at three times at the 1 st weeks of : May, July & September for two seasons. Results indicated that, all the natural sources for Anti-stress compounds positively improved Washington navel orange tree (growth & physiological performance, initial fruit set & retention and yield as :a number & weight & fruit quality. Whereas, Chitosan compound has a superior effect with significant difference on the above parameters, when compared to other treatments under this study for both seasons. Moreover, anti-stresses compounds under study could be arranged Chitosan, Ascorbic acid, Prolin and Vitamin E respect., as for their effetivness.
