Agricultural production continues to be limited by a number of biotic and abiotic factors that reduce crop yield and quality. Potassium (K) is an essential nutrient that affects most biochemical and physiological processes that influence plant growth and metabolism. It also contributes to the survival of plants exposed to various biotic stresses. The following review is about diseases, Pests drought saltiness Emphasizes the emerging role of K in defense against biotic and abiotic stresses, including cold and frost and waterlogging. K availability and plant growth; anatomy Morphology and its effects on plant metabolism are discussed. Physiological and molecular mechanisms of K function in plant stress tolerance are reviewed. This article highlights the future needs for research on the role of K in agriculture to improve plant stress tolerance by modifying K fertilizer inputs.
The world population is growing rapidly and will exceed its current number of 7.0 billion to 9.4 billion by 2050. to provide enough food for the growing world population; To meet the food needs of future generations while conserving our planet’s ecosystems and energy resources, a massive increase in crop production is needed. However, abiotic (e.g., pests and weeds) and abiotic (e.g., drought, salinity, cold, frost, and runoff) factors that can significantly reduce the quantity and quality of crop production continue to limit agricultural production. 28.2% wheat yield due to biological stress; rice loss 37.4%; corn 31.2%; potato loss 40.3%; Evidence indicates that it causes 26.3% soybean and 28.8% cotton losses. At the same time, Yield loss due to biological stress was 65.8% for corn; 82.1% for wheat; 69.3% for soybean and 54.1% for potato [3].
During their evolution, plants have developed a wide range of mechanisms to resist various stress conditions. A growing body of evidence demonstrates that minerals play an important role in plant stress tolerance [4–8]. Among all minerals, potassium (K) plays a particularly important role in plant growth and metabolism, and it greatly contributes to the survival of plants under various biotic stresses. We know the importance of K fertilizer for crop production and its quality. As a consequence, potash consumption has increased significantly in most regions of the world. A strong positive relationship between K fertilizer input and grain yield was shown. [10]
Pdf) Potassium Substitution By Sodium In Plants
K is an essential nutrient and the most abundant cation in plants. The concentration of K
Apoplastic K, which is always found to be between 100 and 200 mM in the cytoplasm.
The concentration can vary between 10 and 200 mM or can reach up to 500 mM [12]. K is enzyme activity; protein synthesis; combination of light, osmoregulation; Stomach movement energy transfer; phloem transport; It plays an essential role in cation-anion balance and stress resistance [4].
This review focuses on various biotic (pathogens and insects) and abiotic (drought, salinity, cold and frost, and runoff) impacts. availability of K for plant growth; anatomy and morphology; Plant metabolism is discussed. This review discusses the roles of K in stress tolerance mechanisms and evaluates the potential for improving plant tolerance by modifying K fertilizer input and selecting appropriate plant species or cultivars.
The 6 Essential Nutrients For Healthy Plants
Growing evidence shows that crop production is significantly limited by biotic stresses. Oerke and Dehne [13] reported that between 1996 and 1998, insects (32%) and animal pests (18%). It is estimated that fungi and bacteria (15%) and viruses (3%). Total available production for eight major crops (wheat, rice, maize, barley, potato, soybean, sugar beet and cotton). In many cases, K-deficient plants are more susceptible to infection than those with adequate K supply. For example, in the absence of K supply, the rate of symbiont germination is greatest, but in the presence of K, the rate decreases rapidly. [14] (Table 1) increased. Similar results were observed with infection of Discula destructiva Redlin in Cornus florida L. [15]. Williams and Smith [16] also reported that K fertilization significantly reduced stem rot incidence and AgSS, and found negative correlations between leaf K percentage and disease severity. K fertilization has been widely reported to reduce insect infestation and disease incidence in many host plants. Perrenoud [17] reviewed 2449 references and found that application of K significantly reduced the incidence of fungal diseases by 70%, bacteria by 69%, insects and mites by 63%, viruses by 41% and nematodes by 33%. Meanwhile, K increased the yield of plants infected with fungal diseases by 42%, bacteria by 57%, insects and mites by 36%, viruses by 78% and nematodes by 19%.
Application of K fertilizer reduces the incidence of most diseases, but sometimes has no effect or even the opposite effect. Prabhu et al[18] noted that the effect of K on disease incidence can be classified as “increased”, “decreased” and “no effect” or “variable effect” (Table 2). Variable effects of K on pathogenesis include K amount and source; It can be affected by plant and pathogen species and the type of experiment. Nam et al[19] found that strawberries with K excess were susceptible to infection by the anthracnose pathogen Colletotrichum gloeosporioides, but its resistance was greatly improved when K was not supplied. Low plant K status increases reactive oxygen species (ROS) and auxin; This result was observed because reactive oxygen species (ROS) such as ethylene and jasmonic acid (JA) stimulate the synthesis of molecules including phytohormones [5, 20].
It reduces the internal competition of microbes for nutrient resources [15]. This nutrient status allows plants to allocate more resources to building strong cell walls to protect against infection and insect attack, allowing more nutrients to be used for plant defense and damage repair. [21] DeDatta and Mikkelson [22] reported that tillering and tillering rates increased in the presence of adequate K concentration due to increased plant resistance. When airborne pathogens (especially from bacteria and viruses) are present in sufficient K levels, the mouth functions well and is prevented by rapid closure of pathogen entry.
K is essential for the function of various plant enzymes, and it regulates the metabolic pattern of higher plants and ultimately alters the metabolic rate [4, 21]. In K sufficient plants, proteins, It significantly increases the synthesis of high molecular weight compounds such as starch and cellulose, and soluble sugars such as organic acids, Reduces the content of low molecular weight compounds such as amino acids. amides in plant tissues. These low-molecular-weight compounds are important for infection and insect attack development, and low concentrations make plants less susceptible to disease and insect attack in K-sufficient plants. Adequate K increases phenol content, which plays an important role in plant resistance. Also, Sarwar [14] concluded that the low pest damage in plants with high K was due to low pest preference under adequate nutrients.
