Abstract: A field experiment was conducted at Regional Sericultural Research Station, Koraput, Orissa to study the effect of graded doses of potassium on mulberry (Morus alba L.). Graded doses of potash (0 to 60 kg K2O ha-1yr-1) alongwith recommended doses of nitrogen and phosphorus were applied to a medium–K sandy loam red soil under rainfed condition. Analysis of three years’ pooled data revealed that the growth attributes, yield, nutrient uptake, net return and benefit: cost ratio were influenced significantly due to potash application up to 60 kg K2O ha-1yr-1.
