He unferti-and fruitsAgronomy 2021, 11,eight of3.four.1. Leaves Arbuscular mycorrhizal fungi (AMFs) and plant-growth-promoting rhizobacteria (PGPR) contributed to higher phosphorus concentration in leaves, which we also confirmed with regards to nutrient ratios (Figure 2). Beneath AMF + PGPR inoculation versus the uninoculated handle, the ratios of P to Ca and Mg GS-626510 site within the leaves that we observed were significantly higher. This partnership also concerned the P/N ratio, except for the 9 of 16 Agronomy 2021, 11, x FOR PEER Evaluation unfertilized handle, where the mycorrhizal remedy had no impact around the P content material. The AMFs contributed to significantly higher P/K ratios when the N-100 and N-50h doses have been applied.P:K0.30 0.P:Ca0.Ab AbAb AbAbBb Bab Aab Aa0.14 0.12 0.ten 0.08 0.06 0.Ac Ab Aab Aab AaBb BabBb BaBab0.Aa0.15 0.ten 0.05 0.0.02 0.non-inoculatedN-0 N-50 N-inoculatedN-50+50 N-50hnon-inoculatedN-0 N-50 N-inoculatedN-50+50 N-50hP:Mg1.20 1.P:N0.Ac0.80 0.60 0.40 0.20 0.BbcBb Bb BaBc0.10 0.08 0.06 0.04 0.02 0.Ac Ab AbAb AaAbBa Ba BaBbAab Ab Aab Aanon-inoculatedN-0 N-50 N-inoculatedN-50+50 N-50hnon-inoculatedN-0 N-50 N-inoculatedN-50+50 N-50hFigure 2.

Fruits Microbial inoculation decreased the K/Ca ratio within the fruit from the unfertilized control trees and improved it when the N-50h dose was applied (Figure three). Mycorrhizal inoculation influenced the P/K ratio in fruits according to the N fertilization therapy. AMFsAgronomy 2021, 11,9 of3.4.2. Fruits Microbial inoculation decreased the K/Ca ratio in the fruit from the unfertilized Etiocholanolone manufacturer handle trees and elevated it when the N-50h dose was applied (Figure 3). Mycorrhizal inoculation influenced the P/K ratio in fruits based on the N fertilization remedy. AMFs improved the provision of P in the absence of N fertilization and with all the N-100 dose, and decreased P when the N-50+50 and N-50h therapies have been applied. Working with AMF inoculum impacted the P/Mg ratios in the fruits (Figure three). Higher values of this parameter have been Agronomy 2021, 11, x FOR PEER REVIEWnoted for plants treated with AMF + PGPR inoculum. AMF + PGPR enhanced the K/Ca ratio in fruits using the N-50h treatment and lowered the ratio for the N-0 remedy in comparison towards the uninoculated handle (Figure 3).10 ofP:K0.14 0.12 0.ten 0.08 0.06 0.04 0.02 0.P:Ca2.Ab Bb Bb Ab AaBbAbBb Ba AaAa2.00 1.50 1.00 0.50 0.Aab Aab Aab AaAaAa AaAa Aanon-inoculatedN-0 N-50 N-inoculatedN-50+50 N-50hnon-inoculatedN-0 N-50 N-inoculatedN-50+50 N-50hP:Mg1.20 1.00 0.80 0.60 0.40 0.20 0.K:CaAc Aab Ab Aab AaBbcBb Bb BaBcBb20 15 ten 5Aab Aa Aa AaAaAaAaAa Banon-inoculatedN-0 N-50 N-inoculatedN-50+50 N-50hnon-inoculatedN-0 N-50 N-inoculatedN-50+50 N-50hand lowercase letters indicate significa.
