Application of Novel Microorganism-Based Formulations as Alternative to the Use of Iron Chelates in Strawberry Cultivation

The strawberry is a low-growing, herbaceous perennial plant, sensitive to iron deficiency. deficiency represents nutritional disorder, leading decreased content of photosynthetic pigments, which determines the yellow color characteristic chlorotic leaves. Therefore, in calcareous soils, use synthetic chelate often mandatory cultivation. employment novel microorganism-based formulations as alternatives chelates, was evaluated during cultivation by monitoring morpho-biometric parameters, chlorophylls, leaves and roots, Fe reductase activity involved absorption chlorosis event plants using strategy I. experimental design envisaged growing seedlings on an inert substrate (pumice), irrigated with Hoagland solution iron-free, 12 h photoperiod. After 42 days, at first appearance symptoms, were transplanted into soil, after seven they treated, single application, (MBF), inoculum (In) Trichoderma spp. Streptomyces spp., or Sequestrene (Sq). Strawberry sampled analyzed 5, 10, 15, 20 days from treatments. results showed that positively affected seedlings, reducing producing comparable effects treatment.
