Seeding Rate and Cultivar Impacts on Nutrient Uptake of Field Pea under Fertile Soil Condition
Open accessAbstract
Plant density is an important agronomic factor that affects crop growth, development, and yield.The optimum plant density to attain the highest yield can vary with genotype, production and, environmental factors.A field experiment was conducted at Bursa Uludag University Agricultural Area to evaluate the effects of seeding rate and variety on plant nutrient uptake of field pea (Pisum sativum L.) cultivars (Ulubatli, Kirazli, Golyazi, and Urunlu).Some very important factors responsible for low yield are plant density under field conditions and the selection of unsuitable cultivars.The adoption of pea cultivars that are more productive and better adapted to cultivation regions and the increase in plant population per area are important strategies to obtain higher productivity under field conditions.Plant density is one of the most effective agronomic factors for determining optimum plant nutrient uptake.The factorial experiment was arranged in a completely randomized block design with three replicates per treatment.Four cultivars and five seeding rates (75, 100, 125, 150, and 175 g seed m -2 ) were evaluated.Results showed that plant nutrient uptake was affected by seeding rate and pea cultivars.The maximum rate of plant nutrient uptake occurred at a density of 100-125 g seed m -2 and for 'Kirazli', 'Golyazi', and 'Urunlu'.However, 'Ulubatli' showed minimum values of nutrient uptake.Regarding macroand micronutrients, varieties on the average had mean nutrient uptake with the following sequence: N > K > Ca > P > Mg, Na, Fe > Mn > Zn > Cu.Pea varieties and seeding rates should be considered in the fertilization program.

Higher seed densities can lead to increased competition for limited resources, resulting in reduced seedling growth and greater variability in germination outcomes.
“Some studies [32,33] have shown that higher seed densities can lead to increased competition for limited resources, resulting in reduced seedling growth and greater variability in germination outcomes.”
From Optimizing Water, Temperature, and Density Conditions for In Vitro Pea (Pisum sativum L.) Germination (2024) · cites this paper as [32]
The Introduction states that competition for water, light, and nutrients increases with planting density and that plant growth tends to decrease. The Results and Discussion also report reduced shoot and branch numbers at higher seeding rates. The paper does not establish reduced seedling growth specifically or greater variability in germination outcomes; a search for germination, seedling emergence, and variability found no supporting passage.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
