The Influence of Different Fertilization Strategies on the Grain Yield of Field Peas (Pisum sativum L.) under Conventional and Conservation Tillage

Abstract

Weather, tillage, and fertilization are the major factors affecting the grain yield of field peas (Pisum sativum L.). However, the impact of tillage and fertilization on yield is not well understood. Therefore, this experiment was initiated in 1999. In this manuscript, we report the data recorded during the period of 2011–2015 to quantify the impacts on yield. Field peas were planted in seedbeds prepared through conventional tillage (CT)—moldboard ploughing to the depth of 0.22 m; and minimum tillage (MT)—disking to the depth of 0.12 m. The crop received three fertilization treatments, including zero fertilization (control); nitrogen, phosphorus and potassium (NPK) mineral fertilization treatment; and NPK mineral fertilization plus the incorporation of pre-crop biomass. Five years’ average data indicated the highest yield on fertilized treatments (2.85–2.98 t ha−1 vs. 2.66 t ha−1) regardless of the tillage. When comparing the yield of fertilized treatments, the yield under CT (2.98 t ha−1) was significantly higher than that of MT (2.85 t ha−1). However, on non-fertilized treatments (less fertile plots), a higher yield was recorded under MT (2.71 t ha−1) compared with CT (2.40 t ha−1). Overall, the results of this study suggest that fertilizer application together with incorporation of the above-ground biomass of the previous crop may help sustain pea grain yield.

Effects of Fertigation Management on the Quality of Organic Legumes Grown in Protected Cultivation

“…In addition, the fertilizer requirements in legumes are low, particularly nitrogen fertilization, which is not generally required or is required in small amounts, although the application of "starter" nitrogen fertilization at a low dose rate seems to enhance the nodulation process and onset of nitrogen fixation in most of the legume crops [37], including peas [38] and French beans [39]. Thus, normally, peas grown in fertile soils are not very dependent on fertilization, particularly on N doses, except during the initial stage of development [40], while in French bean an increase in fertilization, up to a threshold, significantly augmented green pod yield [41]. Therefore, the differences in yield responses between species to different fertilizer amounts applied could be due to higher fertilizer requirements of French beans with respect to pea varieties.…”

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

“…However, other studies have shown that in soil with a high nitrate–nitrogen content, starter N application had a detrimental effect on pea germination, and nodulation and seed yield [ 17 ]. The efficiency of fertilizers is governed by meteorological conditions and the nutrient content in the soil [ 18 , 19 ]; therefore, recommended NPK rates can vary widely [ 20 , 21 ]. The phosphorus and potassium requirements of peas vary depending on the growing conditions [ 20 ].…”

Effects of Variety, Spacing and Nitrogen Application on Chickpea (Cicer arietinum) Growth and Yield in Embu County, Kenya

“…In the current study, plant biomass reflects the amount of sunlight, water, and mineral resources that a plant can capture and turn into plant mass (Sims et al, 2012;Macák et al 2020). The spacing of 50x10cm had significantly higher biomass compared to the other wider spacing.…”
