The influence of mycorrhizal fungi (Glomus sp.) on field pea plant survival and growthin drought caused stress conditions

Abstract

The influence of mycorrhizal fungi on field pea green mass yield, dry matter yield, grain yield, number of pods per plant, number of grains per pod, average number of plants per m2, grain concentration of nitrogen, phosphorus and potassium were studied in the greenhouse during two investigative years. The best results with all parameters were obtained in both investigative years by seed inoculation with the mycorrhizal species G. mossae. The exceptions were mean green mass yield, dry matter yield and the number of grains per pod in the second investigation year (irrigation rate - 240 mm/m2) where better results were achieved by seed inoculation with species G. intraradices. The highest green mass yield obtained by seed inoculation with mycorrhizal species Glomus mossae was 671.45 g/m2, dry matter yield 59.40 g/m2, grain yield 346.20 g/m2 whereas grain nitrogen concentration was 4.08%. Far better results of all yield and quality indicators of this plant compared to non-mychorrized variants were accomplished by mycorrized variants in water lacking conditions.
