Potassium fertilizer promotes the thin-shelled Tartary buckwheat yield by delaying senescence and promoting grain filling

The application rate of potassium fertilizer is closely related to the yield of crops. Thin-shelled Tartary buckwheat is a new variety of Tartary buckwheat with the advantages of thin shell and easy shelling. However, little is known about application rate of potassium fertilizer on the yield formation of thin-shelled Tartary buckwheat. This study aimed to clarify the effect of potassium fertilizer on the growth and yield of thin-shelled Tartary buckwheat. A field experiment to investigate the characteristics was conducted across two years using thin-shelled Tartary buckwheat (Miku 18) with four potassium fertilizer applications including 0 (no potassium fertilizer, CK), 15 (low-concentration potassium fertilizer, LK), 30 (medium-concentration potassium fertilizer, MK), and 45 kg·ha−1 (high-concentration potassium fertilizer, HK). The maximum and average grain filling rates; starch synthase activity; superoxide dismutase and peroxidase activities in leaves; root morphological indices and activities; available nitrogen, phosphorus, and organic matter content in rhizosphere soil; urease and alkaline phosphatase activities in rhizosphere soil; plant height, main stem node number, main stem branch number, leaf number; grain number per plant, grain weight per plant, and 100-grain weight increased first and then decreased with the increase in potassium fertilizer application rate and reached the maximum at MK treatment. The content of malondialdehyde was significantly lower in MK treatment than in other three treatments. The yields of thin-shelled Tartary buckwheat treated with LK, MK, and HK were 1.22, 1.37, and 1.07 times that of CK, respectively. In summary, an appropriate potassium fertilizer treatment (30kg·ha−1) can delay the senescence, promote the grain filling, and increase the grain weight and final yield of thin-shelled Tartary buckwheat. This treatment is recommended to be used in production to achieve high-yield cultivation of thin-shelled Tartary buckwheat.

Foliar applied potassium nanoparticles (K-NPs) and potassium sulfate on growth, physiological, and phytochemical parameters in Melissa officinalis L. under salt stress.

Salinity stress significantly constrains agricultural productivity and vegetation decline worldwide, particularly in Iran. Potassium, the second most prevalent nutrient in plants, is well known to be essential for cell metabolism. Here, the effects of potassium fertilizer in two biogenic nanoparticles (K-NPs) and conventional (potassium sulfate) forms (0.1 mg/ml) on Melissa officinalis L. under salinity (0, 50, 100, and 150 mM) were investigated. The results demonstrated that stress markers (electrolyte leakage, malondialdehyde, and hydrogen peroxide) increased as salinity levels increased. Plant growth parameters (shoot and root length, fresh and dry weight of shoot and root) and physiological and photosynthetic parameters (stomatal conductance, relative water content, chlorophyll fluorescence, and photosynthetic pigments) were reduced in salinized plants. The highest reduction in fresh weight root, dry weight root, fresh weight shoot, dry weight shoot, root length, and shoot length was recorded under 150 mM NaCl by 30.2%, 51.6%, 30.5%, 24.7%, 26.4%, and 21%, respectively. In contrast, bulk potassium sulfate and K-NPs increased these parameters. Furthermore, K-NPs improved M. officinalis tolerance to NaCl toxicity by enhancing the content of osmolytes such as proline, soluble sugars, and antioxidant enzymes, improving antioxidant contents such as phenols, tannins, anthocyanins, and flavonoids; increasing total protein; and lowering stress markers in plant tissues. Given the results of the physiological, biochemical, and phytochemical parameters obtained from this study, it can be stated that K-NPs, in comparison to the conventional form of potassium fertilizer, exhibit a greater potential to mitigate damages caused by salinity stress in M. officinalis plants.

Effects of phosphorus and potassium fertilization and fruit canopy position on sugar accumulation in mangifera indica cv. 'Kent' pulp

Sugar content is the key to mango quality and growers are constantly seeking methods to optimize it. In this study, fructose, glucose, sucrose, and maltose sugars were evaluated to determine how phosphorus and potassium fertilizers in varying amounts could affect these sugar levels and how sunlight exposure effects fruit. The experiments were conducted in the KALRO Orchard of Kiambu County, Kenya. Thirty-five healthy 7- to 8-year-old ‘Kent’ trees were selected and divided into five treatment groups with five replicates each. Treatment with 1 kg, 2 kg P, K and combined PK per tree resulted in a significantly higher fructose content than the control. In contrast, neither 1 kg nor 2 kg P resulted in significantly higher glucose contents than the control. Combined PK fertilizers at 0.5+0.5 kg per tree reduced fructose and increased glucose, sucrose, and maltose. A combination of PK fertilizers at 1.0+1.0 kg significantly increased only fructose, but not other sugars. Even after applying P and K fertilizers, the position of the fruit canopy did not affect fructose, glucose, or maltose contents. However, there was a trend towards a higher sucrose content in fruits exposed to sunlight (5.17 g/100 g) than in canopy fruits (2.29g/100g), although this difference was not statistically significant. The same trend was observed for the other sugars. The t-test revealed no significant differences between the two canopy positions (t = 1.01, p = 0.344). A significant difference in sugar content (p < 0.05) between fruits harvested at different canopy positions suggests that fruits harvested at different canopy positions did not ripen simultaneously. In contrast, neither 1 kg nor 2 kg of P produced a significant difference in the glucose content. Combining PK fertilizers at 0.5+0.5 kg per tree decreased fructose while increasing glucose, sucrose, and maltose. A combination of PK fertilizers at a rate of 1.0+1.0 kg significantly increased only fructose but not other sugars. Even after the application of P and K fertilizers, the position of the fruit canopy did not affect fructose, glucose, and maltose contents. However, there was a trend towards a higher sucrose content in fruits exposed to sunlight (5.17 g/100 g) than in crown fruits (2.29 g/100 g), although this difference was not statistically significant. The same trend was observed for the other sugars. The t-test revealed no significant differences between the two canopy positions (t = 1.01, p = 0.344). A significant difference in sugar content (p< 0.05) between fruits harvested at different canopy positions suggests that fruits harvested at different canopy positions did not ripen simultaneously.

Modeling the effect of fertilizers on cotton yields and cotton fiber quality on saline soils in so uthern Kazakhstan

   Yntymak st.,26, Kazakhstan Cotton in Kazakhstan is one of the strategically important crops and is cultivated in the extreme south of the republic in the Turkestan region, in the northernmost cotton-growing zone on the globe. The aridity of the climate, the shortage of irrigation water and the growing threat of the risk of increasing saline lands in cotton plantations, on the one hand, and the insufficient and unjustified use of minerals, on the other, are the main limiting factors in cotton production. On the industrial plantations of the peasant farm "Sabyr", v. Atakent, Maktaaral district, Turkestan region, field experiments were carried out on serozems of slightly and moderately salinity in 2022. In experiments on two salinity backgrounds, 9 identical treatments of fertilizers with different doses and ratios of nitrogen, phosphorus and potassium were studied. During the phases of budding, flowering and fruit formation of cotton, biometric studies and selection of plant samples were carried out to study photosynthetic and yield indicators depending on fertilizers on 2 salinity backgrounds. The effect and interaction of fertilizers and the amount of salts in the soil on the formation of leaves in various phases of cotton development isquite accurately described (R2 = 0,957-0,972) by regression equations. At the same time, the effect of single action of nitrogen and potassium fertilizers was negative, and that of phosphorus fertilizers was positive. During the growing season, double combinations of all the studied factors, with the exception of nitrogen and potassium, had a negative effect on the dynamics of accumulation of cotton plant biomass. The gross cotton yield is 86% determined by the complex total influence of nitrogen, phosphorus and potassium fertilizers and the degree of soil salinity. At the same time, the unilateral effect of nitrogen and potassium fertilizers and soil salinity on cotton yield was negative, and that of phosphorus fertilizer was positive. There is a high correlation between potassium nutrition and fiber quality indicators (r = 0,38-0,62). Changes in fiber quality indicators generally had a strong relationship with the amount of salts in the topsoil (r = 0,51-0,61).

Comparative analysis of archival data on yields of main field crops from fertilizer experiments on different soil types in Bulgaria

The main aim of the study was to systematize and summarize archival data on yields from main field crops from multiple fertilizer experiments of Nikola Poushkarov ISSAPP on various soil types in Bulgaria. A large set of results from the field fertilizer experiments carried out on four different soil types: Calcareous Chernozem (Trastenik village), Haplic Chernozem (Gorni Dabnik village), Haplic Luvisol (Nikolaevo village) and Planosol (Sekirovo village) in the geographical network of Bulgaria of the Nikola Poushkarov ISSAPP has been accumulated. Eight fertilization variants were tested with annual application of potassium (0, 8, 16 and 32 kg/da K2 O) on two backgrounds of nitrogen (N) and phosphorus (P) fertilization. Crop rotation during the individual years was as follows: wheat (Triticum aestivum L.), maize (Zea mays L.), sunflower (Helianthus annuus L.) and sugar beet (Beta vulgaris L.), grown under non-irrigation conditions. Optimum rates of fertilization with the main nutrients, N, P and K have been established for the different soil types. There are complex interactions between the different rates of fertilization with the main macronutrients and this has a significant impact on the quantity and quality of agricultural crop yields. The difference in yields between the two investigated periods (1963-1970 and 1971-1975), at the same levels of fertilization, shows that the level of yields and accordingly, the use of nutrients are also determined to a significant extent by the climatic conditions. With an increase in the fertilizer rate, the yields also increase, and the rates of 16 kg and 32 kg K2 O remain the most effective, regardless of the occurrence of potassium accumulation in these variants. This was also confirmed by the results of the analysis of variance of the yields of cultivated crops. There was a pronounced increase of the effect of potassium fertilization in soils less supplied with this element, i.e. the Haplic Luvisol (Nikolaevo village) and Planosol (Sekirovo village). The effect of the potassium fertilization increases and expands in well supplied with potassium soils, but possessing unfavorable conditions for nutrition with this element, as in the case with the Calcareous Chernozem (Trastenik village). There was also an effect of potassium fertilization, although inconsistent, in soils well supplied with potassium, such as Haplic Chernozem (Gorni Dabnik village).

Effect of potassium fertilization on storage root number, yield, and appearance quality of sweet potato (Ipomoea batatas L.).

Increasing storage root number is a pivotal approach to enhance both storage root (SR) yield and appearance quality of sweet potato. Here, 2-year field experiments were conducted to investigate the effect of 0 (K0), 120 (K1), 240 (K2), and 360 (K3) kg ha-1 potassium fertilizer (K2O) on lignin metabolism, root growth, storage root yield, and uniformity. The results demonstrated that potassium (K) application led to a decrease in the activities of key enzymes involved in lignin biosynthesis, including phenylalanine deaminase (PAL), 4-coumarate coenzyme A ligase (4-CL), cinnamic acid dehydrogenase (CAD), polyphenol oxidase (PPO), and peroxidase (POD). This resulted in a significant reduction in lignin and G-type lignin contents in potential SRs compared to K0 treatment within 10-30 days after planting (DAP). BJ553 exhibited a significant decrease in PAL activity, as well as lignin and G-type contents at 10 DAP, whereas YS25 showed delayed effects until 20 DAP. However, the number and distribution of secondary xylem conduits as well as the mid-column diameter area in roots were increased in K2 treatment. Interestingly, K2 treatment exhibited significantly larger potential SR diameter than other treatments at 15, 20, and 25 DAP. At harvest, K2 treatment increased the SR number, the single SR weight, and overall yield greatly compared with K0 treatment, with an average increase of 19.12%, 16.54%, and 16.92% respectively. The increase of SR number in BJ553 was higher than that of YS25. Furthermore, K2 treatment exhibited the lowest coefficient of variation for both SR length and diameter, indicating a higher yield of middle-sized SRs. In general, appropriate potassium application could effectively suppress lignin biosynthesis, leading to a reduction in the degree of pericycle lignification in potential SRs. This promotes an increase in the number of storage roots and ultimately enhances both yield and appearance quality of sweet potato. The effect of potassium fertilizer on lignin metabolism in BJ553 roots was earlier and resulted in a greater increase in the SR number compared to YS25.

Effect of potassium fertilizer dose and compost dose of empty palm oil bunches (EFB) on the growth of lemongrass (Cymbopogon nardus L.)

This study aims to determine the effect of potassium fertilizer and compost of Empty Palm Oil Bunches (EFB) on the growth of citronella (Cymbopogon nardus L.). The research was started in February-June 2022 at BPTP Banten, and the Laboratory of the Department of Agroecotechnology, Sultan Ageng Tirtayasa University. This study used a factorial Randomized Block Design (RBD) method which consisted of two factors. The first of potassium fertilizer dose has 4 levels, 0 kg/ha potassium (K0), 15 kg/ha (K1), 30 kg/ha (K2) and 45 kg/ha (K3). The second factor of EFB compost has 4 levels, 0 tons/ha (T0), 20 tons/ha (T1), 30 tons/ha (T2) and 40 tons/ha (T3). The results showed the dose of potassium fertilizer 30 kg/ha gave the best results on plant height parameters at the age of 3, 4, 5, 6 weeks after planting (WAP). Dosage of 40 tons/ha of EFB compost gave the best results on the number of leaves aged 5 and 6 WAP. There was no interaction between the dose of potassium fertilizer and the dose of EFB compost on all.

Potassium fertigation and organic fertilisation in ‘Syrah’ grape in Northeastern Brazil: yield, must characteristics and phenolic compounds

The effect of both potassium and organic fertilisation on grape yield and must composition originating from wine grapevines cultivated in the São Francisco river basin, in the semi-arid region of Northeastern Brazil, is not well known. Since soils from that region usually have low organic matter content, we hypothesise that soil application of organic fertiliser and potassium application through drip irrigation enhances the availability of this nutrient in the soil, and it influences grape yield and quality. Hence, five doses of potassium (0, 20, 40, 80 and 160 kg ha-1) applied through a drip irrigation system and two doses of goat manure as organic fertiliser applied into the soil (0 and 7.5 m3 ha-1) after pruning were evaluated concerning yield and berry quality of grapevine ‘Syrah’ over four growing seasons (April 2013 to July 2015) in Petrolina, state of Pernambuco, Brazil. The experimental design was randomised blocks with 5 replications. We evaluated yield (t ha-1), weight of 100 berries (g), must volume (mL), total soluble solids (°Brix), pH and total titratable acidity (‰), K, Mg and Ca contents and phenolic compounds (total polyphenols, anthocyanins and flavonoids). The increasing application of potassium at the different doses of organic fertiliser did not alter the crop yield, except in the second season. Nonetheless, K concentration in grape must was influenced in the four growing seasons, with higher values at fitted K2O doses by polynomial regression of 83.62 kg ha-1 (first season), 101.25 kg ha-1 (second season), 120.00 kg ha-1 (third season) and 77.99 kg ha-1 (0 m3 ha-1 organic fertiliser) and 96.07 kg ha-1 (7.5 m3 ha-1 organic fertiliser) in the fourth season. The addition of increasing doses of potassium interfered with the wine grape quality, which is an important factor to be considered in relation to its acidity. Organic fertilisation did not affect the most quality characteristics of the grapes.

Effects of potassium fertilization on cesium-133 absorption by persimmon trees

In 2011, the Fukushima Daiichi Nuclear Power Station accident released radioactive materials, such as cesium (Cs), into the atmosphere and dropped onto agricultural land soil. Reducing radioactive Cs absorption from the soil is important for crop production. Therefore, persimmons were cultivated in pots with different amounts of potassium (K) fertilizer (+0 g, +20 g (standard level), and +40 g of K sulfate/pot), and the concentration of 133Cs in leaves and fruits was investigated. Additionally, the effects of phlogopite (materials expected to enhance K availability and radioactive Cs fixation in the soil) were investigated. K fertilization increased the exchangeable K concentration in the soil, and as the investigation continued, a significant difference in the K concentration in the leaves was observed. From the beginning of the 133Cs measurement, the 133Cs concentration in the leaves and fruits was significantly higher in the treatment without K fertilization. When the exchangeable potassium concentration in the soil was approximately 200 mg K2O kg−1 or less, the 133Cs concentration in the leaves tended to increase sharply. This suggests that controlling the Cs concentration in persimmon plants is possible by maintaining the exchangeable K concentration in the soil through K fertilization.

There combination of yield components and nutrient balance of chickpea plants by using DRIS methodology, by using; split split block design with three factors (N, P, and K) 36 treatment with 3 replicates was used. The main results could be summarized as The combination between Nain plot potassium, Sub main plot nitrogen, and Sub sub main plot phosphorus levels affected the yield of the chickpea plant significant also the maximum yield was recorded in treatment combination (K2N1P2) was (1.55Mg ha-1). Whereas the lowest mean value (0.73Mg ha-1) was recorded from the treatment combination (K0N0P0). The combined effect of nitrogen, phosphorus and potassium fertilizer on nutrient balance indices (NBI) and yield in chickpea plants. The lowest nutrient balance index was recorded from the treatment combination (K2N1P2).

Effect of different potassium fertilizers on yield and quality of tomato (Solanum lycopersicum L.) under drought stress conditions

The experiment was carried out in open field conditions in Ciğir village, located in the Idil district of Sirnak province, during 2020 tomato growing season. The aim of the study was to investigate the effect of different potassium (potassium chloride, potassium sulfate and potassium nitrate) fertilizers on yield and quality characteristics of tomato plants (Fereng genotype and Kamenta F1 variety) grown under drought stress. The fertilizers were foliar applied at a dose of 1%. Irrigation treatments of the experiment were full irrigation (control, 100%), 66% of the full irrigation, and 33% of the full irrigation. Leaf temperature, relative water content of leaf, chlorophyll content, fresh and dry weight of green parts, membranes injury index, soluble solid content (SSC) in tomato juice, pH of tomato juice and total yield were determined. The results indicated that drought stress had a significant adverse impacts on yield and quality of both Fereng genotype and Kamenta F1 variety. The application of potassium nitrate and potassium sulfate caused an increase in the chlorophyll and water soluble solid content. Potassium chloride application resulted in a reduction in membrane damage. The effects of potassium sulfate fertilizer on yield was significantly higher than the other two potassium fertilizers.

The Effects of Potassium Fertilizer on the Active Constituents and Metabolites of Bulbs from Lilium davidii var. unicolor

Lilium davidii var. unicolor (Lanzhou lily) is rich in nutrients, making it an important economic plant widely used in the fields of food and medicine. In this study, potted lily bulbs were treated with nutrient solutions containing K+ and nutrient solutions without K+ (CK and KT). The contents of nutrients in lily bulbs at different stages after treatment were compared. It was found that the application of potassium fertilizers increased the content of total phenols, flavonoids, and flavanols in lily bulbs and the antioxidant activity in the bulbs. Simultaneously, the study observed that potassium fertilizers could impact the accumulation of polysaccharides and saponins. Furthermore, employing non-targeted metabolomics, the secondary metabolites of mature Lanzhou lily bulbs were scrutinized both with and without potassium fertilization (KT and CK). A total of 607 metabolites were identified, including 573 in positive ion mode and 34 in negative ion mode. These metabolites were classified into 13 categories at the superclass level, with lipids and lipid molecules (37.93%), organic acids and their derivatives (16.52%), organic oxygen compounds (14.88%), and phenylpropanoids and polyketides (13.61%) being the most prominent. Differential metabolite enrichment analysis between the experimental and control groups showed that the differential metabolites were mainly concentrated in metabolic pathways related to amino acid biosynthesis, such as arginine and proline metabolism, beta-alanine metabolism, alanine, aspartate, and glutamate metabolism. Additionally, it was found that the application of potassium fertilizer increased the accumulation of amino acids in Lanzhou lily bulbs. Overall, this study provides a theoretical reference for the development of nutrients and efficient cultivation techniques for L. davidii var. unicolor bulbs.

Application of potassium fertilizer and plant growth regulators to the growth and productivity of purple sweet potato

The study aimed to determine the effect of plant growth regulators and potassium fertilizer on the growth and productivity of three clones of purple sweet potato. The experiment was conducted at IPB University experimental station in Leuwikopo Dramaga Bogor for seven months. The study used a split-plot design with three factors and three replications. The first factor was as a subplot, namely plant growth regulators (PGR) application which consisted of two levels of without PGR (S0) and with PGR (S1) concentration of 2 cc l-1 of water (2,000 ppm). The second factor was as a subplot, namely rates of potassium chloride fertilizer (60, 120, 180 kg ha-1 K2O). The third factor as the main plot was sweet potato clones of (K1) Ayamurasaki, (K2) RIS-03063-05, and (K3) MSU 03028-10. The concentration of 2,000 ppm PGR did not significantly affect growth and tuber yield components. Potassium chloride K2O of 60 kg ha-1 up to 180 kg ha-1 did not significantly affect growth and tuber yield components. MSU 03028-10 clone had the highest total tuber yield (1537.8), healthy tuber (1529.9), unmarketable tuber (740.3), and small tuber (709.0). MSU 03028-10 clones have the longest stem length and the largest number of leaves 3-12 WAP. This study indicates that the MSU 03028-10 clone produces better growth and productivity than other clones.

The Effect of Various Levels of Nitrogen, Phosphorus and Potassium on Production Of Local Red Onion (Allium Cepa L .)

Fertilization is one of the efforts done by farmers to increase the production and quality of onions. The research aimed to find out the effect of different levels of nitrogen, phosphorus, and potassium fertilizers on the growth and production of onions. The research was conducted in the Grdarash field, the experimental farm of the College of Agriculture, University of Salahaddin. The research used a spilt–spilled design. The first factor was nitrogen (0, 40, 80, 160 Kg .ha1 ). The second factor was phosphorus (0, 80, 160 Kg.ha-1 ), and the third was Potassium (0, 50, 100 Kg .ha-1 ). The results indicated a highly significant interaction between NPK and onion bulb yield. The treatment (K1 P2 N1) has the highest significant yield production (18 .36 Mg. ha-1 ) And the best interaction between the nitrogen, phosphorus and potassium fertilizers; this treatment addition was (K 50, P 160 and N 40 Mg .ha-1 ). K1 P1 was the most significant interaction between Potassium and Phosphorus. K1 N1 was the most significant interaction between Potassium and Nitrogen. Keywords: Nitrogen, Phosphorus, Potassium, Onion, Bulb yield

Effect of phosphorus and potassium fertilization on summer greengram (Vigna radiata) varieties

This experiment suggests that the utilization of the greengram variety IPM 02-3 is advantageous due to its superiority in terms of performance and adaptability over other varieties investigated. Additionally, application of 50 kg/ha P2O5 and K2O demonstrates comparable performance and profitability to application of 60 kg/ha P2O5 and K2O, making it an economically favourable option. Soil fertility analysis revealed P and K's role in enhancing nutrient dynamics. The relation between soil nutrient levels and greengram yield underscores the multifaceted relationship. In summary, genetic factors, coupled with optimal nutrient management, synergistically affect the growth and yield of greengram.
