Soybean response (Glycine max L.) under the use of biostimulants: A literature review

Journal of Agricultural Science, 2022

Biostimulants offer a potentially novel approach for the regulation/modification of physiological processes in plants to stimulate growth, to mitigate stress-induced limitations, and to increase yield. The objective of this work was to evaluate the influence of vegetable biostimulants in soybean crop subjected to different soil water conditions. The experiments were carried out in 2017/2018 and 2018/2019, in a completely randomized design (water deficit, combination of biostimulants, and application time). The combinations of biostimulants and time of application were: no combination (control); foliar application at stage V5; foliar application stages V5 and R1; seed treatment; seed treatment and V5 applications; and seed treatment, V5 and R1 applications. All the biostimulant combinations were moreover subject to either the presence or absence of water stress. Evaluations performed were maximum photochemical efficiency, pods per plant, seeds per pod, thousand grain mass, productivi...

The aim of this study was to analyze the effect of biostimulants on the morphological characteristics of soybean seedlings. The testing was conducted in the laboratory of the Faculty of Biofarming in Bačka Topola. The experimental material included three soybean varieties ('Galina', 'Sava' and 'Rubin') selected at the Institute of Field and Vegetable Crops in Novi Sad. The study lasted for two years, 2015-2016, and identical biostimulant treatments were applied in both years. In order to determine the effect of biostimulants on soybean seedling root, hypocotyl and weight, the following commercial biostimulants were applied: EM Aktiv, Terra Green Hobby, Slavol and Bioplant Flora. In addition to the single application of biostimulants, two combinations of Slavol + Bioplant Flora and Slavol + Bioplant Flora + Epin Extra + Slavol S were used as treatments. EM Aktiv showed the greatest effect on root growth. The root was on average 12% longer than the control. Sla...

A three-year study was conducted during 2006-2008 in India (Manipur) to study the response of soybean variety JS 335 to salicylic acid @ 50 ppm, Ethrel @ 200 ppm, Cycocel @ 500 ppm and control (water spray) applied as foliar spray at different stages viz. flower-initiation (40 DAS), pod-initiation (60 DAS) and flower-initiation + pod-initiation. The study revealed that application of Ethrel @ 200 ppm at both flower-initiation (40 DAS) + pod-initiation (60 DAS) gave higher vegetative growth, yield, net returns and B:C ratio as compare to salicylic acid @ 50 ppm, Cycocel @ 500 ppm and control. However, maximum chlorophyll content and carotenoids were obtained from cycocel @ 500 ppm treated plants.

Com o crescente interesse na busca de recursos alimentícios que possam substituir parcialmente o uso de concentrados na alimentação animal, o cultivo da soja para a produção de biomassa e grãos responde como uma alternativa para o setor pecuário. Sendo assim, o objetivo desta pesquisa foi testar doses de fitoestimulante e períodos de corte para avaliar o ganho de fitomassa e a produção de grãos de soja na região do Agreste Meridional do estado de Pernambuco, Brasil. O experimento foi realizado em condições de campo, no município de Garanhuns, avaliando-se quatro doses do fitoestimulante (F1= 0,00; F2 = 3,75; F3 = 7,50 e F4 = 11,25 mL kg-1 de sementes) e quatro períodos de corte (C1= sem corte; C2 = 30 DAE; C3 = 35 DAE e C4 = 40 DAE). A massa seca das plantas foi aumentada com o corte mais tardiamente, o incremento nesse período foi verificado com a aplicação das maiores doses de fitoestimulante, contribuindo na elevação na altura, número de nós e biomassa verde. A dose de fitoestim...

Background: The objective of modern agriculture includes environmental sustainability, low production costs and higher productivity. A biostimulant is a plant material or any other organic compound that not only improves the nutritional aspects also enhances the yield of crops. Black gram and soybean crops of immense economic significance. The growth and yield of these crops are limited by supply of nutrients. Biostimulants consists of amino acids and peptides which helps in growth and development of crops. Methods: The field experiment conducted with randomized complete block design and 4 replications. Effects of different biostimulants at different concentrations as foliar spray and seed treatment for both crops were examined on growth, yield parameters and yield of black gram (TAU-1) and soybean (JS-335) was carried out during kharif 2020. Result: Results showed that foliar application of Quantis biostimulant @ 5 ml L-1 recorded higher growth, yield parameters and seed yield (922 kg ha-1), biological yield (1245 kg ha-1) and production efficiency (13.36 kg day-1 ha-1) in black gram and seed treatment with Epivio energy @ 200 ml 100 kg-1 fetched higher seed yield (1439 kg ha-1), biological yield (1535 kg ha-1) and production efficiency (2974 kg day-1 ha-1) along with higher growth, yield parameters in soybean. It can be concluded that biostimulants will help in achieving higher growth and yield of black gram and soybean.

Castor bean (Ricinus communis L.) is an oil plant of great importance worldwide. It has a very low share in the structure of agricultural crops in Romania, but with a tendency to grow, due to multiple economic advantages. In the context of climate change new approach to cultivation technology is needed. Improving the effects of stressors is the benefit of using biostimulants. Under this circumstances, the aim of this paper is to present the results of the researchers performed in South Romania with respect to the application of biostimulants at castor bean crop.

Soybean (Glycine max) is one of the most important species of the Fabaceae family worldwide, with many and varied uses, such as food, feed and industry sector. The aim of this study was to evaluate the effect of urea fertilizers in comparison with the new types of fertilizers on the agronomic and quality characteristics of soybean. A field experiment was carried out in the experimental field of the Agricultural University of Athens. The experiment was set up in Randomized Complete Block Design, with 4 treatments (control, 100 kg ha-1 urea, 100 kg ha-1 urea with urease and nitrification inhibitors and 75 kg urea with urease and nitrification inhibitors) and 3 replications. There were studied several plant agronomic characteristics such as plant height, leaf area index and seed yield, as well as the seed protein content. According to the results, the agronomic and quality characteristics were affected significantly by treatments. To sum up, soybean is a crop for which there is room in...

Legumes are considered the second most important food source after cereals. One of high protein legume – soybeans is new species for growing in Latvia. Biochemical composition of soybeans is variable dependent on varieties, and highly affected by environmental factors, including fertilisation and the presence of Rhizobium bacteria. Therefore, the present study was conducted to evaluate a chemical composition of soya (Glycine max L) differently fertilized and grown in different places in Latvia. In this study was evaluated protein, fat, fibre content and yield of soybean variety ’Laulema’ grown at different (F1-F6) fertilisation background in Stende and Vilani. Overall results of a three-year analysis (2018-2020) showed that the protein content of soybean ‘Laulema’ ranged from 31.0 to 38.9%, values of total crude fat ranged from 19.4 to 22.4, but crude fibre 10.5-13.7%. Significant difference was observed among fertilisation background, year and climatic conditions. Soybean productiv...
