The increasing of phosphorus availability and corn growth (Zea mays l.) With the application of phosphate solubilizing microbes and some sources of organic materials on andisol

Abstract

Andisol is a soil that develops from volcanic ash material, dominated by amorphous aluminium silicate and Al-humus complex. This research was carried out at the Greenhouse and Laboratory of Soil Biology, Faculty of Agriculture, University of Sumatera Utara, Medan. This research used a randomized block design with 2 treatment factors and 3 replications. The first factor was Phosphate Solubilizing Microbial (PSM), namely: without application (M0), 5 g of Mycorrhiza (M1), 5 gr of Talaromyces pinophilus Fungi (M2), 5 g of Burkholderia cepacia Bacteria (M3). The second factor was organic matter, namely: without application (K0), 180 g of cow dung (K1), 180 g of chicken manure (K2) and 180 g of OPEFB (Oil Palm Empty Fruit Bunch) compost (K3). The research results showed that the administration of phosphate solubilizing microbes and several sources of organic matter could increase the soil pH by 0.61-29.12%, P-available by 1.46-112.64%, plant height by 5.41-19.25% and canopy dry weight by 11.34-65.57%. In general, the best treatment was the application of Mycorrhiza with OPEFB (Oil Palm Empty Fruit Bunch) compost.

Growth stimulation of two legumes (Vicia faba and Pisum sativum) using phosphate-solubilizing bacteria inoculation

“…The type of soil, the amount of nutrients present, and the species of the host plant are some variables that can influence how bacteria behave in soil. Field tests were conducted to assess different PSB strains that might help in the growth of a variety of crops, including chickpeas, wheat, corn, and barley ( Masdariah Sembiring et al, 2019 ; Elhaissoufi et al, 2020 ). However, few studies have been conducted to evaluate PSB inoculation in Broad Beans and Peas.…”

Isolation and characterization of phosphate solubilizing bacteria naturally colonizing legumes rhizosphere in Morocco

“…On the other hand, as discussed by Khan et al (2010) , although there is a clear potential for the development of inoculants with PSBs, their widespread application remains limited by a poor understanding of microbial ecology, dynamics population in soil, and inconsistent performance in a range of environmental factors. However, although PSBs are present in the majority of soils, their performance is strongly influenced by environmental factors such as soil type, temperature, salinity, cation exchange capacity, pH, organic matter, and availability of substances in soils ( Rfaki et al, 2018 ; Masdariah et al, 2019 ). Similarly, Namli et al (2017) stated that resistance to extreme environmental conditions is an important characteristic that allows inoculant bacteria to survive and maintain optimal population numbers throughout a specific crop life cycle.…”

Effect of soil conditioner enriched with biofertilizers to improve soil fertility and maize (Zea mays L.) growth on andisols Sinabung area

“…The treatment combination of soil conditioner and biological agents can increase soil N content for 40.81 % and P available for 49.36 %. The research results of Sembiring et al, 2017b;Masdariah et al, 2019;Siswana et al, 2019 stated that the application of phosphate solubilizing microbes and organic matter can increase the P availability in andisol. Phosphate solubilizing microbes and organic matter are able to produce organic acids so that the availability of nutrient elements in the soil increases (Richardson, 2001;Gyaneshwar et al, 2002).…”
