Theory and Applications

Field experiments were carried out over two growing seasons (2010/11 and 2011/12) to study the effect of potassium (K) fertilization on turmeric (Curcuma longa) on a light textured K deficient soil (Terrace Soil if the Level Barind Tract, AEZ 25) at Shibganj, Bogra, at the Bangladesh Agricultural Research Institute’s (BARI) Spices Research Center (SRC) (Latitude 24°51’0 N, longitude 89°22’0 E, and elevation 23 m). The work was carried out to establish the optimum application rate of K to maximize yield and nutrient uptake of turmeric (var. BARI Holud-3) and to draw up a K balance sheet for K utilization by th
