Integrated Use of Phosphorous in Bt-cotton

All of we know, cultivation of a crop requires nutrients, of which Nitrogen, Phosphorus and Potassium are more important. These nutrients will be supplied in the form of fertilizers which are to be purchased. This comes under part of cultivation cost. These nutrient reserves are also present in our soil but in unavailable form to plants.Therefore if we convert the unavailable form of nutrients to available form by using cheaper sources such as microorganisms it decreases the cost of cultivation and also improves the soil health by reducing the chemical application to soil. Phosphorus is the nutrient which gets fixed in the soil in large quantity at faster rate. Therefore by applying the phosphorus solubilising bacteria to soil converts the fixed unavailable phosphorus in the soil to easily available phosphorus. This book contains experiment conducted in open field on cotton by decreasing the quantity of phosphorus fertilizer which is substituted by Farm Yard manure and Phosphorus solubilising bacteria. This book will be useful to the researchers who are working on fertilizer doses to cotton and any other crop.
