Influence of Azotobacter chroococcum, Azospirillum brasilense, Trichoderma harzianum and Tri-calcium phosphate on hydroponically-grown barley grains

Abstract

This study investigated to evaluate the effect of Azotobacter chroococcum, Azospirillum brasilense, Trichoderma harzianum and Tri-calcium phosphate on sprouted barley grains under hydroponic culture conditions. The results showed that increase of a total weight of sprouted barley grains in treatments of A. chroococcum 257.3 g, Tri-calcium phosphate (TCP) 255.6 g and A. brasilense 254.3 g, whereas T. harzianum + TCP, A. brasilense + TCP and TCP recorded highest height of sprouted barley 25.8, 25.7 and 25.6 cm respectively, the protein ratio in the roots of sprouted barley was increased in A. chroococcum 19.8% followed by T. harzianum 18.4%, while the protein ratio in the vegetative portion was increased in T. harzianum + TCP, A. brasilense + TCP, A. chroococcum and A. chroococcum + TCP which reached 36.4, 32.7, 32.5 and 31.0 % respectively.

Ectomycorrhizal Fungi as Biofertilizers in Forestry

“…Though targeted on exact targets, they constrain nontarget organisms including the soil mycoflora, which eases the growth of plants. Research shows how agricultural sustainability and economic stability depend on fungal biofertilizers [9].…”

The Interaction Effect Between PGPR Bacteria, Mycorrhizae, and Oyster Mushroom Residues on Soil Biological Traits, Yield, and Quantity of Coriander Oil (Coriandrum sativum L.)

“…Microorganisms in the soil rhizosphere play a major role in maintaining soil fertility, and it is essential for the success of crop production due to the growing global demand for food, so the selection of microorganisms is crucial for field application to maintain crop quality, where it is advisable to add nitrogen-fixing bacteria along with bacteria or fungi that dissolve phosphate [1], thus the harmful effects of chemical fertilizers and pesticides can be easily eliminated by adopting biofertilizer strategies in sustainable farming practices [2], [3], in addition to that mycorrhizae fungi increase phosphorus nutrition and micronutrient readiness, and their secretion of glomalin, which increases soil quality, porosity, soil water-holding capacity, and protects plants from pathogens [4]. The performance of these fertilizers is better when used with organic waste, as the effective recycling of mushroom residues and the use of PGPR bacteria improve the utilization of nutrients in sustainable agriculture, which is positively related to growth and yield [5].…”
