“…K-solubilizing bacteria (KSB) can make K associated with mineral available for plant uptake via converting the insoluble or mineral structural K compounds into soluble forms in soil as soil solutions (Zeng et al 2012). Currently, such bacteria are extensively used in biological K-fertilizers (Nath et al 2017;Sarkar et al 2017). It has been shown that KSB, such as Bacillus mucilaginosus and Bacillus edaphicus NBT increased K availability in soils and K content in the plant (Sheng et al 2002;Sheng 2005).…”

This study aimed to investigate the effect of some plant growth promoting rhizobacteria with potassium dissolution ability on different forms of potassium in soil under the cultivation of wheat. The factorial experiment was conducted as a randomized complete design with three replications in greenhouse conditions. The treatments consisted of bacterium inoculation (without inoculation, Enterobacter cloacae Rhizo_33, Pseudomonas sp. Rhizo_9, consortium of Enterobacter cloacae Rhizo_33 and Pseudomonas sp. Rhizo_9), potassium application (2·87 mg K kg−1 of soil and without potassium application).The results indicated that soils treated with Enterobacter cloacae Rhizo_33, either receiving potassium or not, maintain a higher amount of exchangeable K (337 mg kg−1) and water‐soluble K (1·25 and 1·31 meq L−1 with and without K application respectively). The nonexchangeable K and nitric acid‐extractable K values were decreased by inoculating bacterial strains. The grain yield was significantly enhanced by the inoculation of bacterial strains irrespective of rates of potassium application. About 19·16% increase of grain yield was recorded by inoculation of Enterobacter cloacae Rhizo_33 and without potassium application. A significantly greater amount of K uptake in grain was obtained in soils treated with Enterobacter cloacae Rhizo_33, with and without the application of potassium (28·7 and 30·7 mg per pot respectively). There was a significant (P < 0·01) and positive correlation between grain yield and grain, shoot and root K uptake. Potassium uptake had a positive significant correlation with water‐soluble K and exchangeable K; it was negatively correlated with K (HNO3). The data suggested that inoculation of soil with mentioned bacteria can improve plant growth and potassium uptake. Significance and Impact of the Study As one of the macronutrients, Potassium is the most abundant absorbed cation in most plants and exists in soil in different forms. Soluble and exchangeable forms of potassium (K) are important with regard to plant uptake. K‐solubilizing bacteria can convert insoluble potassium to soluble forms; therefore using K‐solubilizing bacteria as biofertilizers is a sustainable solution for the improvement of plant growth, nutrition, root growth, plant competitiveness and reducing the use of potassium chemical fertilizer.

Present irrational crop and nutrient management practices have raised several concerns of high merit. The concerns include low factor productivity or nutrient use efficiency (NUE), declining crop productivity, farmer’s profitability, impaired soil health and ecological contamination. Site-specific nutrient management (SSNM), after considering indigenous nutrient supplying capacity of soil using plant and soil analysis, can feed the crop in synchrony with its nutrient requirement in different physiological growth stages. Besides, several modern geospatial techniques viz. remote sensing techniques, geographic information system (GIS), global positioning system (GPS), proximal sensing; information and communication technologies (ICTs) including decision support system, smartphone apps and web services can also assist in diagnosis of soil and crop nutrient status, fertilizer recommendation and its dissemination to users. Optical and thermal remote sensing can effectively detect crop stress including nitrogen (N) deficiency through several vegetation indices especially normalized difference vegetation index (NDVI). GIS techniques with spatial data acquired by GPS, can create spatial variability map and management zone (MZ) for precise farm operations including variable rate fertilization. Proximal crop sensors viz. chlorophyll meter and Green Seeker can also recognize crop nitrogen status and promote fertilizer N use efficiency by synchronizing fertilizer N supply with crop requirement. Even proximal soil sensing using electromagnetic radiation and contact electrode can estimate soil properties like soil pH, electrical conductivity, major and micronutrient content. Several decision support systems such as QUEFTS based model, crop manager, nutrient expert® and smartphone apps like ‘crop doctor’ can suggest for precise application of agro-inputs to rural youths and farmers. Yield monitoring and mapping tool can generate historical GIS database for spatial variability of crop yield under farmers’ crop management practices and assessment of nutrient uptake. Variable rate machinery based on variability map and sensor technologies can also be used for fertilization under different management zones. Therefore, SSNM technologies can enhance NUE; improve and sustain crop productivity, profitability; avoid nutrient wastage; maintain good soil health and environmental safety.

“…Peanut as a potential oilseed crop requires an adequate amount of nutrients especially phosphorus (P) and potassium (K). Proper nutrient management is the key factor among the best agronomic practices, supporting sustainable crop production for longer run without disturbing soil fertility and health (Sarkar et al 2017;Kumar et al 2018). There is a direct relation between Co-addition of Organic and Inorganic Fertilizers Improves Peanut Production / Intl J Agric Biol, Vol 26, No 2, 2021 the crop productivity and fertilizer usage.…”

Peanut (Arachis hypogaea L.) is the common cash crop of the rainfed areas. Appropriate management practices are very important to get better yield of peanut in sandy loam soil. A field study was carried out during the growing seasons of 2018 and 2019 to evaluate the effect of poultry manure (PM) (37.1 t ha-1), farmyard manure (FYM) (49.4 t ha-1), gypsum (GYP) (2.5 t ha-1), liquid humic acid (HA) (49.4 L ha-1) and co-application of GYP (1.2 t ha-1) and FYM (24.7 t ha-1) on peanut yield, quality and soil physical properties. Application of FYM, PM, HA and GYP (alone or in combination) significantly improved peanut yield, quality and soil physical properties. The combined application of GYP and FYM proved most effective (P ≤ 0.05) in improving the peanut yield (no. of pods per plant, 100 seed weight etc), quality (crude protein and oil content) and soil physical properties (moisture percentage, infiltration rate and bulk density). The combined application of GYP and FYM increased the pods yield by 67 and 65% during 2018 and 2019, respectively than control. Crude proteins (21%) and oil contents (9.0%) were also substantially increased in the combined application. Moreover, the combined application of GYP and FYM significantly retained the soil moisture and reduced bulk density of soil. Present findings suggest that integrated use of FYM and GYP under field conditions could improve the crop productivity, crude protein, oil contents, moisture percentage, and reduce the bulk density of soil thus improving overall soil health. © 2021 Friends Science Publishers
