Productivity of Three Pea (Pisum sativum L.) Varieties as Influenced by Nutrient Supply and Meteorological Conditions in Boreal Environmental Zone

In order to grow crops that reduce the negative impact on environment, as well meet nutritional needs of increasing human population, it is necessary include new and more sustainable production strategies into current agricultural systems. The aim our study was evaluate optimal conditions semi-leafless pea productivity ascertain influence meteorological factors these plants under boreal environmental conditions. test involved three varieties, one which a variety, eight N fertilization treatments were used: (1) without fertilizers (N0), (2) (3) N15, (4) N30, (5) N45, (6) N15+15, (7) N60, (8) N60. Plots second–seventh treatment received base application P40K80; eighth P80K160. Fertilizer efficiency depended Based their productivity, varieties arranged in following descending order: Ieva DS ˃ Respect Simona. Compared with unfertilized peas, NPK enhanced seed yield by 10.6–12.9% average. Splitting N30 rate applying background P40K80, not efficient. N15–45P40K80 for peas determined. Meteorological significantly influenced 75.2%, 44.1%, 79.9% DS, Simona, Respect, respectively.
