Potassium in soil exists in several forms like solution, exchangeable, non-exchangeable and lattice K. These potassium forms are in equilibrium with each other. However, plant takes up K mostly from exchangeable and solution form. The present study was conducted on farmers’ field at Khamkheda (Dist. Bhopal) under the project initiated by Indian Institute of Soil Science (ICAR), Bhopal. The experiment was laid out in a Randomized Block Design (RBD). The entire experimental area at the farmers’ field was divided into five sampling blocks representing the replications to reduce soil heterogeneity. Each block was divided into 4 unit plots with raised bunds as per treatments. | Effect of different doses of potassium on growth, yield attributing characters of rice in vertisol soil of Madhya Pradesh, India
