The yield increasing impact of fertilisation was relatively moderate in the case of pea (700–1500 kg ha-1 yield surplus) and yield surplus was not affected by the given crop year. Crop year significantly affected the optimum N+PK dose of pea (N140+PK in 2011, N105+PK in 2012, N70+PK in 2014) and the efficiency of fertilisation (yield for 1 kg NPK: 9–12 kg, 17–19 kg and 17–24 kg in 2011, 2012 and 2014, respectively in the Nopt+PK treatments).
The performed research showed that the negative effect of sowing date, the main agrotechnical element, on yield (late sowing date) could be partially compensated with proper nutrient and water supply. With optimised agrotechnics on chernozem soil, pea yields of 4.0–5.0 t ha-1 could be safely obtained in the majority of crop years.
