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

Abstract

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

Effect of Mineral Fertilization and Seed Inoculation with Microbial Preparation on Seed and Protein Yield of Pea (Pisum sativum L.)

“…This variant had the highest seed yield (3.66 t ha −1 ). The results of our study are consistent with an earlier study by Janusauskaite [20], in which pea seed yield increased with increasing NPK dose. The positive effect of mineral fertilization on pea seed yields is also confirmed by the studies of Lalito et al, and Chandel et al [42,43].…”

“…On the other hand, the efficiency of N and P uptake by plants is strongly related to K availability in the soil [19]. A balanced plant nutrient supply can therefore improve conditions for the formation of pea productivity and seed quality, with the effectiveness of mineral fertilization varying according to the soil and climatic conditions of the growing area and the weather conditions prevailing during the growing season [20].…”

Spatial Distribution of Soil Macroelements, Their Uptake by Plants, and Green Pea Yield under Strip-Till Technology

“…One of the most important legumes is the pea (Pisum sativum L.) due to its ability to grow in various weather conditions, its high yield and protein content, and its suitability to many cultivation purposes (dry or green seeds, feed and food) [12,13]. P. sativum has the potential to provide 50 to 80% of N necessary for its growth and development through symbiosis, leaving 60-100 kg N for subsequent plants [14,15]. Moreover, it prefers lower temperatures during the growing season and can withstand periodic frosts [16], making it suitable for cultivation in climatic conditions that are less favorable for soybeans.…”

Garden Pea Yield Depends on Sowing Time and Application of Water-Retaining Granules in the Right-Bank Forest-Steppe

“…The widespread use of peas is attributed to their high yield capacity, excellent biological properties, and nutritional value for the human body. Pea seeds are of high nutritional value, they are rich in protein, carbohydrates, phosphorus, vitamins A and B, iron, and calcium, and are easily absorbed (Janusauskaite D., 2023).…”
