In order to study the relative efficiency of potassium schoenite as a source of potassium to rice in comparison with potassium sulphate and potassium chloride at different levels, experiments were conducted during 1973-74 and 1974-75. The results of the study revealed that there was no significant influence of potassium on grain and straw yield of rice varieties IR 8, IR 20. Ponni and Karikalan during both the years. Potassium schoenite being an indigenous product may be preferred if potassium application is desired.
