Abstract
The aim of this study was to determine the effects of different NPK rates and N application methods and seed inoculation with a microbial preparation on selected elements of plant growth and the productivity parameters seed yield, protein content in seeds and the yield of protein. The research hypothesis suggested that seed inoculation and a split rate of N application with an optimal supply of plants with PK could improve the nutritional status and increase the efficiency of nutrient use in peas. The studies included two factors: the application of NPK at doses of N0P0K0 (control), N15P15K15 (pre-sowing), N15P30K30 + N15 (pre-sowing + N15 at BBCH 22–23), N30P30K30 (pre-sowing), N30P45K45 + N15 (pre-sowing + N15 at BBCH 22–23) and N45P45K45 (pre-sowing), and seed inoculation with the microbial preparation Rhizogumin. The results of the study showed significant effects of seed inoculation and mineral fertilization on pea plant growth and the productivity parameters seed yield, protein content and protein yield. It was concluded that among the studied combinations, seed inoculation and the application of mineral fertilizers with fractional nitrogen fertilization with N30P45K45 + N15 were the most effective. This combination significantly increased seed yield, protein content and protein yield compared to the control
treatment (by 26.2%, 11.1% and 43,5%, respectively).
