Abstract – A field experiment was carried out to study the effect of chemical fertilizers and biofertilizers on growth and yield of tomato. Potassium [K] is seventh most common element in the earth s crust. Potassium was isolated in 1807 by Sir Humphry Davy, who obtained it through the electrolysis of very dry molten caustic potash (KOH, potassium hydroxide). Potassium was the first metal isolated by electrolysis and was collected at the cathode (Holmes, 2011). Potassium exists in several forms in the soil, including mineral K, non-exchangeable K, exchangeable K, and dissolved or solution K (K+ ions). Plants can only directly take-up solution K. It exists in exchangeable, non-changeable and in form of soil minerals. Soil inoculation with phosphate solubilizing bacteria (PSB) improves solubilisation of fixed soil phosphorus and of applied phosphates, resulting in higher crop yields. The increase in growth characters might be due to stimulative effect of PSB on P solubilization leading to higher P availability and uptake by plants. Microorganisms enhance the P availability to plants by mineralizing organic P in soil and by solubilizing precipitated phosphates. To enhance the plant’s capacity to utilize such nutrients effectively including in the soil, PSB and VAM inoculation have been considered to be effective. The mycorrhizal fungi mobilize phosphates and other micronutrients like zinc, boron and molybdenum from adjacent soil to the root system through hyphal network. Enhanced uptake of phosphorus and increased plant growth due to inoculation of soil with VAM fungi in horticultural crops.
