“…The application of KMB and FYM recorded significantly the highest plant height at harvest over respective control. The results were conformity with finding of Chaudhary et al [10] and Jha [11] Crop fertilized with K2O @ 60 kg ha -1 , potassium mobilizing bacteria and FYM @ 10 t ha -1 gave significantly the highest green forage (354, 330 and 326g pot -1 ), respectively.Similarly, the application of K2O @ 60 kg ha -1 and KMB recorded significantly the highest dry matteryield (69.95 and 64.29 g pot -1 ) of maize (Table 2). The findings corroborate the reports of Yadav et al [12][13] and Jha [11].…”

A pot experiment was conducted during kharif season of 2019 to carry out the study on “Interactive effect of potash (K2O), potassium mobilizing bacteria (KMB) and FYM on forage yield, nutrient uptake by forage maize and soil fertility in a loamy sand soil of middle Gujarat”. Application of K2O @ 60 kg ha-1, KMB and FYM recorded significantly the highest plant height of forage maize at harvest over respective control. Crop fertilized with K2O @ 60 kg ha-1 and KMB gave significantly the highest green forage and dry matter yield. The results indicated that application of K2O @ 60 kg ha-1, potassium mobilizing bacteria recorded significantly the highest uptake of N, P, K, Fe and Zn by crop at harvest. Significantly the highest uptake of N, K and Cu were found with application of FYM @10 t ha-1. Significantly the highest K uptake by maize as well as higher P and Zn uptake by maize were observed due to interaction effect of K × KMB (60 kg K2O ha-1 with KMB). In case of N and Cu uptake by maize were noted the Significantly higher due to interaction effect of K × KMB (30 kg K2O ha-1 with KMB) and K × KMB × FYM (60 kg K2O ha-1 with KMB and FYM), respectively. The integrated use of potassium fertilizers along with KBM or in combination with FYM significantly improved the maize grain and nutrient uptake.

“…It is required for a plant’s mechanical stability, nutrition, development, reproduction, and resistance to pathogens [ 15 ]. Applying potassium can help to alleviate abiotic stress by increasing photosynthate translocation and enhancing gas exchange, protein synthesis, enzyme activity, and stomatal conductance [ 16 , 17 ].…”

Effect of potassium fertilizer on the growth, physiological parameters, and water status of Brassica juncea cultivars under different irrigation regimes

Abiotic stress, especially a lack of water, can significantly reduce crop yields. In this study, we evaluated the physiological and biochemical effects of potassium sulfate (K2SO4) fertilizer and varied irrigation regimes on the economically significant oilseed crop, Brassica juncea L, under open field conditions. Two cultivars (RH-725 and RH-749) of B. juncea were used in a randomized complete block design experiment with three replicates. Irrigation regimes consisted of a control (double irrigation: once at the 50% flowering and another at 50% fruiting stages), early irrigation (at 50% flowering only), late irrigation (at 50% fruiting only) and stress (no irrigation). The K2SO4 applications were: control (K0, no fertilization); K1, 10 kg ha−1; and K2, 20 kg ha−1. We measured growth via fresh and dry plant weight, plant height, root length, and leaf area. All the growth parameters were higher in RH-749. The physiological attributes, including the membrane stability index and relative water content, were higher at the 50% flowering stage in RH-749. The amount of antioxidant enzymes (catalase (CAT), guaiacol peroxidase (POX), ascorbate peroxidase (APX), and superoxide dismutase (SOD)) was enhanced when both plants were fertilized during water stress. All of these enzymes had higher activity in RH-749. The total chlorophyll content and photosynthesis rate were considerably higher in RH-749, which leaked fewer electrolytes and maintained a less destructive osmotic potential under limited water conditions. The results indicated that it is water-stress tolerant when given a high concentration of K2SO4, which alleviated the adverse effects of water stress on growth and physiology.

“…Phytates represent the most important pool of organic P in soil, but they are poorly available to plants; therefore, phytase/phosphatase enzymes play an important role in increasing P availability (Ramesh et al 2011). Microorganisms are the main source of phytase activity in rhizosphere and bulk soil (Gaind and Nain 2015), and several bacterial and fungal species such as Sporotrichum (Etesami et al 2017;Jha, 2017), through acid and polysaccharides secretion and biofilm formation on mineral surfaces (see Sattar et al 2019). Although these microorganisms are ubiquitous in soil, their activity is influenced by soil properties such as structure, texture, and organic matter content.…”

Smart fertilizers: What should we mean and where should we go?

Highlights- A smart fertilizer allows to control the rate, timing and duration of nutrients release.- Nanofertilizers are powder or liquid formulations which involve the synthesis, design and use of materials at the nanoscale level.- Composite fertilizers are formulations containing nutrients mixed or coated with one or more materials that exploit synergy among materials.- Bioformulations are fertilizers containing active or dormant microorganisms capable to trigger physiological growth responses in plants.- Limited information is available for smart fertilizers on herbaceous crops in open field conditions. Abstract The current agricultural system faces several challenges, the most important being the ability to feed the increasing world population and mitigate climate change. In this context, the improvement of fertilizers’ agronomic efficiency while reducing their cost and environmental impact is one of the biggest tasks. Available literature shows that many efforts have been made to develop innovative fertilizers defined as "smart fertilizers", for which, different interpretations and definitions have been used. This paper aims to define, classify, and describe the new frontier of the so-called smart fertilizers with a particular focus on field-scale studies on herbaceous species. Most of the analyzed papers associate the "smart" concept to the controlled and/or slow release of nutrients, using both terms as synonymous. Some others broadened the concept, including the controlled release of nutrients to reduce the environmental impact. Based on our critical analysis of the available literature, we conclude that a fertilizer can be considered "smart" whenapplied to the soil, it allows control over the rate, timing, and duration of nutrients release. Our new definition is: ‘Smart fertilizer is any single or composed (sub)nanomaterial, multi-component, and/or bioformulation containing one or more nutrients that, through physical, chemical, and/or biological processes, can adapt the timing of nutrient release to the plant nutrient demand, enhancing the agronomic yields and reducing the environmental impact at sustainable costs when compared to conventional fertilizers’.
