“…Potassium helps to maintain the water status of plants under water stress, keeping physiological processes running and thereby increasing the growth and yield in plants like Cicer aritinum L. (Singh & Kuhad, 2005), Triticum aestivum L. (Jatav et al, 2012; Hasanuzzaman et al, 2018) and Zea mays L. (Ul‐Allah et al, 2020). Aksu and Altay (2020) have reported potassium supplementation to increase the relative water content and decrease the MDA content under drought stress in sugar beets, resulting in reduced membrane damage. Potassium application alleviated the drought susceptibility in maize hybrids by improving the water productivity, particularly under water stress (Ul‐Allah et al, 2020).…”

This report discusses water stress-induced changes and their amelioration by added potassium in Sorghum bicolor L. Chlorophylls, carotenoids, and the activity of nitrogen metabolizing enzymes viz., nitrate reductase, alanine aminotransferase and aspartate aminotransferase were adversely affected under water stress and restricted irrigation. Osmotic as well as water stress trigger ROS production while potassium ameliorated these changes to some extent and increased the activity of SOD, CAT, APX, and GR and the contents of GSH and AsA. Water stress-induced changes ultimately reflecting on growth and yield parameters like plant height, biomass yield, grain yield, days to flowering, and days to maturity. Added potassium affected these parameters positively, both under normal and stress conditions, indicating the use of potassium as a tool for mitigating the water stress induced deleterious changes in sorghum to some extent by enhancing the nitrogen use efficiency and strengthening the enzymatic and non-enzymatic antioxidant components. The results obtained here exhibited similar trends in seedlings and plants raised in sand cultures and field conditions, making them more meaningful and comprehensible. | INTRODUCTIONInadequate water supply is one of the important factors that limit crop productivity and grain quality. The severity of water stress depends not only on the magnitude and duration of the stress, but also on the developmental stage of the plant at which the stress is imposed.Water stress not only modifies the morphology of a plant but also severely affects its metabolism (Khan et al., 1993;Ober et al., 1991;Saeed et al., 1997). Altered cellular metabolism in response to water stress results in reduced growth and crop yield because of excess production of ROS and damage to cell membranes, proteins, nucleic acids, and other components of the cell (Gill & Tuteja, 2010;Tambussi et al., 2000). Limited water supply affects physiological and biochemical processes in plants such as photosynthesis, enzyme activities, plant water relations, integrity of membranes, all in all resulting in metabolic dysfunctions (Abid et al., 2018;Gill & Tuteja, 2010). Water deficit induces the oxidative stress in plants by the excess production of reactive oxygen species (ROS), which have the potential to cause membrane dysfunction and the leakage of important cellular components like mineral ions, e.g. K + (Blokhina et al., 2003;Kapoor et al., 2020). Potassium (K) nutrition to plants stimulates root growth, which helps with the efficient absorption of soil water (Saxena, 1985). Potassium treatments improved dry matter and total nitrogen content in faba bean plants subjected to restricted water supply during the post flowering period, probably by promoting growth and not by enhancing the nitrogen fixation efficiency (Kurdali et al., 2002). K availability to plants was reported to be related to soil water content, which highly influenced the mass flow and diffusion rates of K in soils (Doussan et al., 2003).

“…A influência das doses de K na produtividade da beterraba nos experimentos foi bem explícita. Em beterraba o K aumenta o teor de açúcar, melhora a regulação osmótica, reduz as atividades antioxidantes não enzimáticas produzidos pela planta com fins de defesa em situação de estresse, o que gera maior crescimento e produção da planta (Mubarak et al 2016;Aksu & Altay, 2020).…”

“…Na cultura da beterraba a extração pode ultrapassar 90 kg/ha de K para produtividades de 30 t/ha (Grangeiro et al, 2006). Atua na ativação enzimática, síntese de proteínas, turgescência celular e homeostase iônica nas células vegetais, condutância estomática e como importante atenuador do estresse hídrico (Grzebisz et al, 2013;Aksu & Altay, 2020).…”

Objetivou-se com esta pesquisa avaliar a produção da beterraba de mesa (Beta vulgaris) em função da fonte de potássio. O experimento foi conduzido na Universidade Federal de Viçosa -Campus Rio Paranaíba -MG. Dois experimentos, conduzidos nas épocas de verão e de inverno e com a mesma matriz experimental, consistiram da combinação de fontes e de doses de K. As fontes estudadas foram o cloreto de potássio, o sulfato de potássio e o nitrato de potássio. As doses de K foram de 60, 120 e de 240 mg/dm³ de K.

“…One of the main tasks of the state policy in Kazakhstan in the area of healthy nutrition of the population for the period up to 2020 is to increase the share of produced functional foods that contribute to the effective provision of the human body with the required amount of micro-and macronutrients. Work [8] describes the issue related to providing the population with healthy food. Therefore, in the current situation, it is a relevant and expedient task to devise and implement new technologies and an assortment of products of mass consumption, such as bakery, confectionery, dairy products enriched with essential nutrients that compensate for the shortage of essential components in food.…”

The composition of legumes and sugar beet contains a large number of useful mineral and vitamin substances. The use of composite flour from leguminous crops for the preparation of bakery products helps increase food and biochemical properties. The main objects of this research are chickpea flour, bean flour, dry sugar beet powder, and wheat flour of the first grade. The main problem is an insufficient amount of minerals and vitamins, so the purpose of this work is to enrich bakery products and replace sugar in the recipe with sugar beet powder. The results showed that composite flour and sugar beet increased calcium content by 13.54 mg/100 g, iron ‒ by 0.57 mg/100 g, potassium ‒ by 141.03 mg/100 g, phosphorus ‒ by 38.89 mg/100 g, vitamin A ‒ by 0.002 mg/100 g, vitamin B2 ‒ by 0.016 mg/100 g, vitamin E ‒ by 0.32 mg/100 g, and vitamin PP ‒ by 0.405 mg/100 g. Microbiological indicators meet the established norms and requirements; the amount of mesophilic aerobic and facultative-anaerobic microorganisms, yeast, and mold in the test bun was the least compared to the control sample. As a result, it was proved that the use of composite flour of leguminous crops contributes to an increase in the nutritional and biological values of bakery products, and the application of dried sugar beet powder makes it possible to completely exclude sugar from the formulation of the resulting product. Employing this technology and formulations for obtaining bakery products makes it possible to expand the range of bakery products, reduce the duration of the manufacturing process, improve the quality of finished products, increase labor productivity. That also contributes to the improvement of the socio-economic indicators of bakery and confectionery enterprises
