Effect of amino acid biostimulant on the yield and nutraceutical potential of soybean

Abstract

Advancement in crop cultivation technologies strives to increase the yield and improve the quality of crops under minimized threats posed to the natural environment. Application of biostimulants is a treatment which increases crop yield and quality particularly after plants exposure to stress conditions. The objective of the work was to determine changes in yield and nutraceutical potential of soybean (Glycine max [L.] Merr.) 'Atlanta' after application of biostimulant. A field experiment was conducted in three growing seasons (2014-2016). Terra Sorb Complex biostimulant was applied in the growing season in the form of single or double spraying in two concentrations (0.3% and 0.5%). Number of biostimulant applications and its concentration modified yield and quality of crop and also the nutraceutical and antioxidative potential of soybean. Foliar application of biostimulant improved yield of soybean (increased by 25% compared to the control) without any negative effect on the nutritive value of seeds. The application of biostimulant increased (compared to the control) number of pods and seeds (32%), plant height (38%), phenolic content (34%), flavonoids content (74%), and reducing power (210%). Taking into account biometric traits of soybean plants, positive effects were observed in the case of single biostimulant applications with lower concentration. The conducted study demonstrated a significant increase in the soybean yield and antioxidant potential after double application of the tested biostimulant at higher concentration. On the other hand, total fat and protein content was higher in plants treated once with a lower product concentration.

Pure Organic Active Compounds Against Abiotic Stress: A Biostimulant Overview

“…Their exogenous application allows the plant to save energy in their synthesis, thus increasing its capacity to use its resources for growth or to cope with stresses ( Popko et al, 2018 ). The positive effects of amino acid-based BSs are well known, and these products are widely marketed ( Botta, 2013 ; Cerdán et al, 2013 ; Popko et al, 2018 ; Kocira, 2019 ; Tadros et al, 2019 ). Most of the amino acids used are the 20 proteinogenic ones, but non-proteinogenic amino acids (npaa) can also be found.…”

Biochemical and economical effect of application biostimulants containing seaweed extracts and amino acids as an element of agroecological management of bean cultivation

“…Biostimulants were used in terms when the foliar application of microelements is recommended. Their doses were established based on the authors' experience from previous investigations 35,38 .…”

“…Although current predictions indicate a continuous increase in the use of biostimulants in both organic and sustainable agriculture, still little information can be found on the implementation of this agrotechnical treatment in bean cultivation. Our team has already conducted research on the influence of biostimulants on the yield and chemical composition of bean 14 , 19 , 35 – 37 and soybeans seeds 7 , 9 , 38 . The results clearly showed that the plant response depended on the composition and doses of the preparations.…”

Morphological and Biochemical Responses of Glycine max (L.) Merr. to the Use of Seaweed Extract

“…Soya (Glycine max (L.) Merrill.) is one of the most important leguminous plants that are cultivated around the world because it is a precious source of both protein and fat [1,2]. Its use for production of food, oil, and fodder means that the demand for this plant is continuously growing [3].…”
