Effect of Rhizobium inoculation and foliar spray with salicylic and ascorbic acids on growth, yield and seed quality of pea plant (Pisum sativum L.) grown on a salt affected soil, New Valley-Egypt

Abstract

A field study was carried out to investigate the effects of seed inoculation with bio-fertilizer (Rhizobium), foliar spray with antioxidants i.e., salicylic acid (SA), ascorbic acid (AA) and SA+AA at 250 mg L -1 of each and their interactions on growth, yield components and some seed bioconstituents of pea plant (Pisum sativum L.) cv. Master-B grown on a salt affected sandy loam soil (EC=9.65 ds m -1 ), New Valley-Egypt during seasons of 2015/2016 and 2016/2017 towards maximizing its productivity under salt stress conditions. Pea seeds were inoculated with Rhizobium as a bio-fertilizer source before planting. Pea seeds were inoculated at sowing with N fixing bacteria (Rhizobium leguminosarum). The application of antioxidants to plants was done as foliar spraying after twenty days after planting and repeated three times a ten days interval. The following data were recorded, vegetative growth parameters, root nodule characteristics, leaves photosynthetic pigments content, fresh as well as dry yield characteristics and seed chemical compositions. Inoculation significantly increased all the studied traits of pea plant grown under salinity conditions compared with un-inoculation. Foliar spraying of pea plants with antioxidants also, significantly increased all the studied aspects of pea plant, SA+AA was more efficient than spraying either solely. Inoculation seeds with Rhizobium and foliar spray of SA+AA significantly increased all the studied characteristics. SA+AA along with inoculation was more effective in increasing all the studied characteristics. Inoculation with Rhizobium along with foliar spraying with SA+AA could be recommended for growing pea under saline conditions.

Effect of some Treatments Stimulating Growth and Yield on Pea Plants Grown under High Temperature Conditions

“…By enhancing the performance of the photosynthetic system, it has the capacity to improve carbon assimilation, enhance biomass generation, and ultimately increase crop yield. The obtained results are in harmony with those of Noufal (2018). The same trend was found for both studied seasons.…”

“…Also, certain growth regulators, such as cytokinins can stimulate plant growth and yield even under high-temperature conditions (Abd El-Hady et al, 2016;Mok, 2019), as this hormone promotes cell division, elongation, and flowering, which can enhance the overall productivity of pea plants. On the other hand, the application of antioxidants, such as ascorbic acid (Hamail et al, 2015;Noufal, 2018) or melatonin (Yusuf et al, 2020;EL-Bauome et al, 2022;El-Beltagi et al, 2023), can help scavenge ROS and protect pea plants from oxidative stress. Also, the application of chemical compounds such as potassium citrate, a combination of potassium and citric acid, can improve nutrient uptake, root growth, and stress tolerance in pea plants (Gebaly et al, 2013).…”

Berseem Clover Productivity in the Presence of a Combination of Biofertilizers, Organic Fertilizer and Biochar Under Sandy Soil Conditions

“…Biofertilizers are products applied on the surface of a plant or in soil and contain live microorganisms that promote plant growth and development. These products may include bacterial species such as Rhizobium, Azotobacter, and Azospirilium as well as blue green algae (BGA) (Kumar et al, 2017 andNoufal et al, 2018). The need for N fertilizers could be reduced by biological nitrogen fixation (Nicolás et al, 2006) in other mean bio-fertilizers (Ewees and Abdel Hafeez, 2010).…”
