We compared the effect of biotisation techniques on growth and mineral uptake in nursery-grown micropropagated Myrobolan 29C plants, against conventional techniques. Biotisation techniques consisted of inoculation of mycorrhizas (Glomus intraradices) and bioagents (Trichoderma harzianum), moreover, the soil borne pathogens were controlled through antagonist microorganisms. Nutrients (N, P, K) were supplied based on plant demand for biotised plants whilst they were empirically supplied for the conventionally managed block. Biotised plants showed a double growth (total dry matter) compared to control plants (34 g/plant against 18 g/plant) despite a significant reduction of the amounts of nutrients supplied. A fertigation plan is proposed to reduce undue mineral elements application by matching the plant demand for nutrients.

Abstract

We compared the effect of biotisation techniques on growth and mineral uptake in nursery-grown micropropagated Myrobolan 29C plants, against conventional techniques. Biotisation techniques consisted of inoculation of mycorrhizas (Glomus intraradices) and bioagents (Trichoderma harzianum), moreover, the soil borne pathogens were controlled through antagonist microorganisms. Nutrients (N, P, K) were supplied based on plant demand for biotised plants whilst they were empirically supplied for the conventionally managed block. Biotised plants showed a double growth (total dry matter) compared to control plants (34 g/plant against 18 g/plant) despite a significant reduction of the amounts of nutrients supplied. A fertigation plan is proposed to reduce undue mineral elements application by matching the plant demand for nutrients.
