Abstract
Phosphorus availability from rock phosphate (RP) can be improved through composting with organic manure and phosphate-solubilizing microorganisms in the soil to enhance phosphorus status and plant growth in alkaline and calcareous soils of Pakistan. An experiment was designed to determine the impact of arbuscular mycorrhizal fungi on Mentha arvensis with varying doses (0%, 50%, and 100%) of rock phosphate and organic manure (FYM). When compared to non-inoculated plants, the growth responses of M. arvensis to AM inoculation with rock phosphate and organic manure were pronounced. Mycorrhizal dependencies increased with increasing rock phosphate and organic manure levels, which were 40.82% and 46.92%, respectively. The results showed that M. arvensis produced a higher percentage of essential oil for AMF inoculation at higher and lower rock phosphate and organic manure levels. In terms of nutrient uptake by mycorrhizal plants, there was a significant improvement in macro and micronutrients in all tested mycorrhizal plants compared to non-treated plants. The nutritional value of M. arvensis rises with the amount of fertilizer added. Results proved that as fertility levels rise, the number of spores (150 to 190/100 g of soil) and the percentage of infection (70.51 to 95.23%) also increase. The findings imply that inoculating plants with AMF might increase phosphorus solubility from rock phosphate and organic manure. Local rock phosphate and organic manure may reduce reliance on expensive commercial synthetic fertilizers and increase crop yields.
