“…However, at KH stage there was no significant difference in plant height owing to different treatment imposition, except T1(0% RDK) and T6 [0% RDK + KSB (ST) +KSB (SD)] treatment. Numerical increment of plant height with increase dose of potassium might be due to proper photosynthesis and cell growth which is in consonance with Swetha et al [14]. On the other hand, after KH stage there was some significant changes in leaf area index (LAI) and drymater due to treatment imposition.…”

An experiment was conducted on potassium sufficient sandy loam soil (Alfisols) to evaluate the impact of potassium solubilizing bacteria (KSB) on the performance of rabi sweet corn. The study consisted of 10 treatments with different doses of potassium with and without KSB treatment [Seed treatment (ST) + Soil drenching (SD) at Knee height (KH) stage]. Result of this experiment indicated that sweet corn yield was gradually reduced with reduction of recommended dose of potassium (RDK) irrespective of KSB treatment. Amongst all treatments, application of 100% RDK in 2 equal splits at sowing and KH stage + KSB (ST + SD) (T10) resulted in highest growth, yield (19.7 t ha-1) and yield attributes. However, T10 was on par with the result of [100% RDK + KSB (ST) + KSB (SD) at KH stage], (50% RDK at basal + 50% RDK at KH stage), [100% RDK+ KSB (ST) +KSB (SD) at KH stage] and [75% RDK at basal + KSB (ST) +KSB (SD) at KH stage] treatments. Whereas, implication of 25% or 50% reduction of RDK was significantly inferior to 100% RDK. The study revealed that KSB could substitute 25% of RDK supplied to nutrient exhaustive crop like rabi sweet corn without compromising the economic yield in potassium rich alfisols of semi-arid tropic.

“…The highest total drymatter was recorded in M 1 (190.79 and 196.96 Potassium promotes photosynthesis by increasing the capturing carbon and enzyme rubisco and encouraging synthesis and assimilates transport in developing plant which helps to increase the dry weight of leaves, shoot, root and total dry weight (Swetha et al, 2017). Swetha et al (2017) reported that application of potassium @ 60 kg K 2 O ha -1 as well as sulphur @ 40 kg S ha -1 increased the dry weight of leaves, shoot, root and total plant at 30, 60 DAS and at harvest in maize. Gheibi et al (2009) observed that shoot and root dry weights were increased in maize seedlings treated with different nickel levels and supplied with urea instead of ammonium nitrate.…”

“…Combination of the farmyard manure with Ksulphate was to most effective to achieve high grain yields with good quality and leads to sustainable food production (Holík et al, 2018). Swetha et al (2017) showed that application of potassium at a rate of 60 kg ha -1 combined with sulphur significantly increased the dry weight of leaves, shoot, root and seed yield of maize plants.…”

A pot experiment was conducted under greenhouse condition at the Experimental Farm, Faculty of Agriculture, Zagazig University, Egypt. The experiment aimed to study the effect of different potassium sources (potassium sulphate and potassium feldspar) at the recommended rate (40 mg K kg-1) either single or in combination with soil amendments i.e., farmyard manure (FYM) and sulfur (S) with or without silicate dissolving bacteria (SDB) on yield and nutrients uptake by wheat through the investigated clayey soil. Soil were taken from the surface layers (0-30 cm) from Hehia District, Sharkia Governorate, Egypt. Application of K-sulphate or K-feldspar as individual application or combined with different soil amendments under SDB gave increase in straw and grain yield, potassium uptake, biological yield, 1000 grain weight and protein content of wheat plants compared to untreated soil. The highest value for each of yield, K-uptake and available K was found in clayey soil treated with K-sulphate combined with FYM plus S in the presences of SDB, while the lowest ones were obtained with untreated soils in absence of soil amendments and SDB. Application of Ksulphate showed greater value in each of yield, protein content, K-uptake by wheat plants and soil available potassium than K-feldspar. Application of SDB to K-sulphate or K-feldspar increased yield, protein content, K-uptake of wheat and available potassium compared to the untreated ones.
