Response of Normal and Low-Phytate Genotypes of Pea (Pisum sativum L.) on Phosphorus Foliar Fertilization

Abstract

Phosphorus (P) is an important nutrient in plant nutrition. Its absorption by plants from the soil is influenced by many factors. Therefore, a foliar application of this nutrient could be utilized for the optimal nutrition state of plants. The premise of the study is that foliar application of phosphorus will increase the yield of normal-phytate (npa) cultivars (CDC Bronco a Cutlass) and low-phytate (lpa) lines (1-2347-144, 1-150-81) grown in soils with low phosphorus supply and affect seed quality depending on the ability of the pea to produce phytate. A graded application of phosphorus (H₃PO₄) in four doses: without P (P0), 27.3 mg P (P1), 54.5 mg P (P2), and 81.8 mg P/pot (P3) realized at the development stages of the 6th true leaf led to a significant increase of chlorophyll contents, and fluorescence parameters of chlorophyll expressing the CO2 assimilation velocity. The P fertilization increased the yield of seeds significantly, except the highest dose of phosphorus (P3) at which the yield of the npa cultivars was reduced. The line 1-2347-144 was the most sensible to the P application when the dose P3 increased the seed production by 42.1%. Only the lpa line 1-150-81 showed a decreased tendency in the phytate content at the stepped application of the P nutrition. Foliar application of phosphorus significantly increased ash material in seed, but did not tend to affect the protein and mineral content of seeds. Only the zinc content in seeds was significantly reduced by foliar application of P in npa and lpa pea genotypes. It is concluded from the present study that foliar phosphorus application could be an effective way to enhance the pea growth in P-deficient condition with a direct effect on seed yield and quality.

Phosphorus and naphthalene acetic acid increased the seed yield by regulating carbon and nitrogen assimilation of flax

“…Moreover, this study found that P application improved flax seed yield, which is consistent with previous reports ( Muhammad et al., 2020 ; Xie et al., 2020 ; Xie et al., 2022 ). Similar results have been observed in other species, such as soybean ( Yin et al., 2016 ; Taliman et al., 2019 ), pea, canola ( Yin et al., 2016 ), wheat ( Škarpa et al., 2021 ), maize ( Škarpa et al., 2021 ), and rice ( Škarpa et al., 2021 ). In this study, the application of P fertilizer had a significant influence on both 1000-seed weight and the number of capsules per plant in flax, which is consistent with previous research findings ( Hocking and Pinkerton, 1993 ; Xie et al., 2016 ).…”

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

“…Pea varieties respond differently to fertilization [ 23 , 28 ] and environmental conditions [ 2 ]. The main traits that determine the level of adaptability in peas are a high harvest index, good ripening, disease resistance, resistance to shatter, high potential yield, seed weight, and seed number per pod [ 25 , 29 ]. In this study, the variety Ieva DS demonstrated the greatest adaptability and the ability to produce the highest seed yield of all studied varieties, regardless of the weather conditions.…”

Bionanotechnology in Agriculture: A One Health Approach

“…Phosphorus, for example, is a vital element for all plants, as it is essential for growth, photosynthesis, protein structure, and the formation of nodules for flow formation, among others. [ 87 ]. In cereals and legumes, the primary storage form of phosphorus is in the form of phytic acid.…”
