Previous reports on phosphorus solubilizing microorga- nisms have attributed the differences in phosphate solubilization when ammonium and nitrate were used to the use of different mechanisms for the generation of acidity in the culture.
Therefore, more experiments are needed to explore the effects of microorganisms on the growth of kiwifruit, so as to provide theoretical basis for the application of microbial fertilizers in the growth of kiwifruit.
The application of PGP bacteria CI resulted in a fairly strong growth-promoting effect on kiwifruit plantlets. Burkholderia is known as N-fixing bacteria and exhibited antifungal activity Stephen and Jisha, ; Mubarik et al. In recent years, microbial fertilizer has become more and more widely used in agricultural applications.
Microbial fertilizer is used to optimize the microbial in the soil, and to further improve the effect of the beneficial microorganism on the plant. Further, and as described below, the preferred method of can also include controlling for various factors in the biocomposting and bioaugmentation processes After the peer review process for each manuscript, few of them are published.
Yeasts were identified using Biolog Micro station identification system. The skin is thick and easy to fall off, and the endothelium is pink. May 20, ; Accepted: A phosphate containing culture supernatant is estimated using the protocol described by Ryan et al.
Identification of phosphate solubilizing microorganisms Yeast identified by biolog micro station was tested for their phosphate solubilizing ability.
The kiwifruit is rich in mineral elements such as N, P and K, which not only directly affect the nutritional value of the kiwifruit, but also are closely related to its taste and storage.
Quantitative estimation of P solubilized by the selected isolates was conducted by following Lynn et al. June 30, Correspondence: From the previous studies, it can be seen that phosphate solubilization of phosphate-solubilizing bacteria is one of the important mechanisms to promote the growth of plants [ 19 ].
One of the multiple pathways that PGPRs promote plant growth is to manipulate root growth Biswas et al. Effects of the Complex Inoculant on the Availability of Soil Nutrients The level of soil available N Figure 3DP Figure 3Eand K Figure 3F differed significantly between the Control and the CI treatments, indicating that an improvement in soil fertility was achieved through the inoculation of this complex inoculant.
The soil yeasts Candida tropicalis, Geotrichum candidum, Geotrichum capitatum, Rhodotorula minuta and Rhodotorula rubra solubilized insoluble phosphate.
The available P was determined according to the published methods . Phosphate plays an important role for the process of photosynthesis and nutrient uptake Illmer and Schinner,while the potassium plays an important role for the growth and reproduction of plants Badr, and the turgidity of guard cells Shehata and El-Khawas, The US biofertilizers market is segmented by microorganisms into rhizobium, azotobacter, azospirillum, blue-green algae, phosphate solubilizing bacteria, mycorrhiza, and other microorganisms.
The solubilizing index showed that two isolates potentially have the highest capability to solubilize P on Pikovskaya solid medium, i. Fertilizer-dependent efficiency of Pseudomonads for improving growth, yield and nutrient use efficiency of wheat Triticum aestivum L.
D. Piccini and R. Azcon, Effect of phosphate-solubilizing bacteria and vesicular-arbuscular mycorrhizal fungi on the utilization of Bayovar rock phosphate by alfalfa plants using a sand-vermiculite medium, Plant and Soil,1, (45), ().
Screening cabbage rhizosphere as a habitat for isolation of phosphate-solubilizing bacteria Hossein Motamedi1,2*, Sholeh Aalivand1, forms of P that are taken up by plants from soil solution are phosphate anions (mainly H and stored at 4 °C temperature before analysis. phosphate-solubilizing bacteria (PSB) and arbuscular inoculated with AMF, the result of which was an mycorrhizal fungi (AMF).increase concentration of both phosphorus and Application of biological fertilizers such as biological nitrogen in the plant biomass .
The inefficient P and K fertilizer can be solved by using Phosphate Solubilizing Bacteria (PSB) and Potassium Solubilizing Bacteria (KSB), as biological fertilizer.
Most of phosphate and potassium in the soil are bound in the form of rocks P, K-minerals and other deposits (Goldstein, ), which can not be absorbed by plants. ii ABSTRACT Nitrogen and phosphorus are essential macronutrients for plant growth.
The major sources of N and P in agriculture are chemical fertilizers. Many bacteria, fungi and a few actinomycetes are potential solubilizers of bound phosphates in soil thus playing an important role making it available to plants in the soluble form. Solubilization of insoluble phosphorus by microorganisms was reported by Pikovskaya.
