Abstract

Garden pea Pisum sativum L. var. Avola inoculated with bacterial suspension of Rhizobium leguminosarum bv. Vicae strain D 293 were grown in the greenhouse until the 15 th day on liquid half strength nutrient solutions of Hellriegel, contained 0,5 mM NO3 - in the all experimental variants. The complementation of nutrients with micronutrients was done according to Hoagland and Arnon excluding Mo from the nutrient medium. The following variants were tested: (1) control plants with root nutrition only and presense of Mo; (2) control plants with root nutrition only without Mo (3) plants with combined root and foliar nutrition (0,1%Agroleaf); (4) plants with combined root and foliar nutrition (0,3%Agroleaf); (5) plants with combined root and foliar nutrition (0,5%Agroleaf). Application of foliar fertilizer in elevated concentrations had a positive effect on the Mo deficient pea plants. An increase of nodule number, plant dry weight, total shoot nitrogen and leaf soluble sugars have been found. The highest nodule number and leaf soluble sugar content was observed at spraying with 0.3% concentration of Agroleaf.
