Phosphate Solubilizing

Phosphorus is usually a limiting factor of acidic tropical soil and limited by the low availability and high cost. The present study aimed to evaluate the interaction of Hangloa vivianite (as phosphorus supply), the selected Mycorrhizal fungi strains (M) and Phosphate Solubilizing Microorganisms (PSM) on maize production in the Adamawa Region of Cameroon. An experimental design with 15 combinations of bacteria strains (B), ( BGL12 as B1, SSL9 as B2, BNBL17 as B3, RBNBL5 as B4, and the combinations of these singles strains, namely B1B2, B1B3, B1B4, B2B3, B2B4, B3B4, B1B2B3, B1B2B4, B1B3B4, B2B3B4, B1B2B3B4) and 05 inputs (mycorrhiza (M), Rock Phosphate (RP) and mixture of M with RP (RP+M)), negative control (C-) and positive control (C+)) was used. After four months of growth, nutrients (Phosphorus and Nitrogen) content and grain yield were assessed. Results indicated that total phosphorus content of M, RP and RP+M plants were 2.42, 2.11 and 4.00 fold higher than that of unfertilized plants. M, RP and RP+M increased maize seeds yield by 26.20%, 26.89% and 165.51% relative to negative control. The benefit of the selected PSM with Mycorrhizal fungi strains (246.76% for N; 216.34% for P) and with the Rock Phosphate (314.23% for N; 167.26% for P) was more pronounced with the combination of RP+M (1030.45% for N and 967.31% for P). These results showed that PSM associated with Mycorrhiza can be used as inoculants to improve the efficiency of vivianite as phosphate fertilizer for sustainable maize production under Sudano-Guinean Climate of Adamawa Cameroon region.

Difference Effect

<p>Rice production in Indonesia can not cover the national needs. The low productivity caused by the decline in soil fertility. One way to increase the phosphorus content in the soil is to provide natural phosphate fertilizer and Azolla inoculum. This study was conducted to determine the proper dose of Azolla inoculum and rock phosphate to increase the availability of phosphate and increase the yield of rice plants on land Alfisol. This study uses the two-factor factorial CRD comparative treatment of manure and fertilizer N, P, K. Analysis of the observed data using analysis of variance at 5% level and if there is a significant difference effect followed by DMRT 5% level to compare between treatments. The results showed that treatment of Azolla inoculum and phosphate can increase the availability of phosphate in the Alfisol soil and can increase rice yield. On the parameters available P showed the highest results in the treatment of Azolla 2.5 tons / ha without natural phosphate and Azolla 5 tons / ha of natural phosphate 350 kg / ha which is 10.81 ppm. In addition, administration of Azolla inoculum and phosphate levels give rise to CEC, organic matter, total N in the soil and soil pH.</p>

A greenhouse experiment was designed to determine the mycorrhizal symbiotic effectiveness in native mycorrhizal fungi population associated with different soil coverage in the Cesar department. The experimental design was completely randomized with nine treatments and six variations per treatment, 54 experimental units in all. Treatments consisted of combination of soils which contained a substrate from different mulches or soil coal mining (soil-coverage): natural forest (NF), transition soil (TS), a horizon (AH), mining waste (MW), palm (PM), pastures (PT), undisturbed soil (US), with its respective controls, positive Glomus mosseae (GM) and negative sterile substrate without inoculum (WI). The variables studied were foliar P content was monitored as a function of time; at harvest, shoot dry weight, shoot P content, and mycorrhizal colonization represented the time increments. The higher contents of P foliar obtained in the sampling period were for the positive control (GM) showing significant differences between soil-coverage, except for ST and US assessed on the sampling day 74. Shoot dry weight had a significant difference in GM, NF, TS, AH, PM and US treatments compared to the remaining three. Treatments with the most weight were US and GM (positive control). Mining waste (MW), PT and WI (negative control) had the lowest values in mass. As expected, shoot P content in the GM samples was higher and had significant differences compared to the other treatments. Soil-coverage closest to the positive control were NF, US, and TS. All assessed treatments showed mycorrhizal colonization except the negative control (WI). Three soil-coverages PM, PT, and US were similar to the positive control, with colonization percentages of 29, 24 and 48 respectively. In conclusion, this kind of research suggests that symbiotic effectiveness experiments are an excellent tool for the selection of native arbuscular mycorrhizal fungi. Besides, and as evidenced, soil-coverage NIT was statistically similar to the positive control (GM), which makes it a candidate for mass crude inoculum production for restoration purposes.

The Impact

AbstractSoil fertility in the Lubumbashi region often proves to be limiting factor for crop production due to their low nutrient reserves. The objective of this work was to evaluate the impact of arbuscular mycorrhizae on phosphorus uptake by maize on Ferralsol. The trial was conducted in pots with 30 kg or 60 kg of P2O5 ha−1 and a control. These three levels of phosphorus were combined or not with arbuscular mycorrhizae. The combinations of 30 kg or 60 kg of phosphorus with the inoculum led to a male flowering of maize at 63 days after semi. Maize treated with 60 kg of phosphorus ha−1 formed very few or almost no blisters in the roots. Cob weight, length, diameter, number of rows and kernel weight varied significantly with phosphorus on both inoculated and uninoculated pots. The inoculated plants had high averages for these yield parameters. Due to the lack of phosphate fertilizer, inoculum alone can be an alternative to phosphorus provided that nitrogen and potassium are added, resulting in small but seed-filled ears compared to the phosphorus-free control without mycorrhizae, which resulted in empty ears. Yield varied significantly with the addition of phosphorus (0.3 to 6.1 tons ha−1) and less significantly with inoculum (3 to 3.7 t ha−1). The combination of treatments showed a significant difference in favour of the 60 kg of phosphorus or 60 kg of phosphorus associated with the inoculum. The highest phosphorus content was obtained on the inoculum treatment alone, which provided 1.4 mg phosphorus g−1 maize compared to other treatments, which provided 0.69 to 0.71 mg phosphorus g−1 maize.
