Plant uptake of phosphorus from sparingly available P- sources as affected by Trichoderma asperellum T34

The contribution of Trichoderma asperellum T34 to the plant uptake of phosphorus (P) from sparingly phytoavailable forms such as insoluble calcium (Ca) phosphates and phytates was studied. Two experiments with cucumber ( Cucumis sativus L.) on siliceous sand were performed involving two factors, nam...

Two experiments with cucumber ( Cucumis sativus L.) on siliceous sand were performed involving two factors, namely: (i) P source, viz.

T34 increased the total content in P of cucumber roots irrespective of the particular P form and enhanced total P uptake by plants with P supplied as Ins6P or PR.
