Nursery managements of in vitro micropropagated rootstocks Myrobolan29C inoculated with biocontrol microorganisms

Two different nursery management processes for in vitro micropropagated rootstock Myrobolan29C were compared over an entire growing season, and during the field research of Sitinplant project. Specifically, the fertilization and soil-born pathogens control techniques routinely adopted by the Small-Medium-Enterprises (SMEs) were examined against those innovated by Sitinplant project. The Sitinplant management process allowed a reduction in the application of nitrogen and potassium by 71 % and 86 %, respectively, and 100 % for phosphorus. Soil-born pathogen control was found to be possible through the inoculation of antagonist microorganisms Bacillus subtilis QST713 and Streptomyces lydicus WYEC108. A substantial increase in plant dry matter accumulation was also observed in the Sitinplant management process plots. Sustainable fertigation plan is proposed to reduce undue mineral elements application by matching the plant demand for nutrients.
