Improving yield of Barley using bio and nano fertilizers under saline conditions

Abstract

The use of nano-fertilizers is an effective alternative to traditional fertilizers, as it achieves many advantages due to its use in smaller quantities, play an important role in plant nutrition and increase the ability of crops to stress through the use of plant growth-promoting (PGP) and phosphates solubilizing bacteria (PSB). A field experiment was carried out at Ras Sudr Research Station of the Desert Research Center. The experiments were conducted to study the effect of nano phosphozink at (50, 100 and 200 ppm) and some phosphate solubilizing bacteria on growth, chemical composition and productivity of Barley in calcareous soil, Treatments were arranged in split plot design with three replicates. The result revealed that, foliar application of Nanophosphozink fertilizer, showed a significantly higher increase of yield parameters of Barley (dry weights of biological yields, straw, grain and plant height) and nutrient contents. Phosphate solubilizing bacteriaas soil drench application (Brevundimonasolei and Acinetobacter baumannii) a repositive to produce proline, organic acids, phosphatase enzymes, catalease enzyme, peroxidase enzyme. They produced higher yields compared with other treatments. The most effective treatment was 200 ppm of Nano phosphozink with Acinetobacter baumannii resulted significant and higher values in this respect compared with other treatments. It could be recommended that Nano phosphozink and the biofertilizer alleviate the hazardous effects of either soil or water salinity, which negatively affect barley seed yield and quality.

The Co-Addition of Soil Organic Amendments and Natural Bio-Stimulants Improves the Production and Defenses of the Wheat Plant Grown under the Dual stress of Salinity and Alkalinity

“…Soil salinity is one of the main factors hindering agricultural development due to the negative impact of soil salinity on production of most agricultural crops (El-Ramady et al, 2018 andAbou Hussien et al, 2020). The high osmotic pressure in the soil solution leads to the plant's inability to absorb the water necessary for its activities, vitality and transpiration (Abdelrahman et al, 2021 andIbrahim et al, 2022). Increasing the soil salinity causes a negative effect on the hormonal balance in the plant, where it causes a decrease in the transfers from roots to leaves and the accumulation of some acids in the leaves (Abo El-Ezz et al (2020).…”

Role of Bio and Nano Fertilization in Increasing Growth and Productivity of Spinach in Sandy Soil

“…In the Central Lab of the Desert Research Center, the samples discreted in water and the size measurements were done at 25°C and a scattering angle of 90 o /173 o . Nano-phosphozinc (contains 18% P from phosphoric acid and 10% Zn from zinc sulphate where solvent in glycerin) was obtained according to Ibrahim and Hegab (2022).…”

“…According to the average data on particle size distribution, nanophosphorus particles have a size of 19.2 nm (Ibrahim and Hegab, 2022).…”

“…The most common nanoparticles in the nature are clay particles, which have the colloidal properties as well. Nowadays, nano-agriculture has penetrated different branches of agriculture including plant nutrition (El-Ramady et al 2018;Rajput et al 2022), nano-enabled agriculture (Wu and Li 2022), nanofertilizers (Ibrahim and Hegab 2022;Shalaby et al 2022), nano-pesticides (Dangi andVerma 2021;Raj et al 2021;Singh et al 2022), nanosensors or nano-biosensors (Saravanakumar et al 2022), nano-food industries (Muthukrishnan 2022), nano-remediation of soil and water (Fei et al 2022), nanoparticles/nanomaterials for ameliorating stress on cultivated plants (Ghosh et al 2022), nanobiofortification for human health (El-Ramady et al 2021a, b), nano-farming (Behl et al 2022, and for sustainable agriculture (Hazarika et al 2022). Recently, many photographic reviews or minireviews have been published such as about smart farming (Fawzy and El-Ramady 2022), soil and humans , management of salt-affected soils (El-Ramady et al 2022b), a comparative review on higher plants and mushrooms (El-Ramady et al 2022c).…”
