Effect of Lime and Potassium on Uptake of Nutrients by Soil and Tubers in Acid Soils

S.M.A.T. Khandakhar, M.M. Rahman, M.J. Uddin, S.A.K.U. Khan and K.G. Quddus


An experiment was conducted in strongly acidic sandy loam soil (pH: 4.5-5.2) to investigate the effect of lime and potassium on nutrient uptake by soil and tuber. Lime was applied at the rate of 0, 0.5, 1.0 and 2.0 t ha-1 and potassium at the rate of 0, 60, 80 and 100 K, kg ha-1. The treatment combinations were allocated to the experimental plots in randomized complete block design. Application of lime and potassium significantly increased total dry matter yield as well as total uptake of nutrients by soil and plant. Lime slightly decreased Mg concentration in haulms and had no effect on tubers.
