Differential response of flooded rice to potassium chloride on two clay mineralogically different soils

Differential response of flooded rice to potassium chloride on two clay mineralogically different soils

Zeitschrift fur Acker und Pflanzenbau 154(2): 101-103

In pot experiments at IRRI, Philippines, grain yield of rice grown on (a) a Laguna clay soil in which amorphous material dominated the clay fraction and given 0 or 75 kg K/ha was 51 and 80 g/pot and straw yield was 74 and 117 g/pot for the 2 K rates, resp. When grown on (b) a Cabantuan clay soil dominated by vermiculite corresponding yields were 65 and 67 and 113 and 88 g/pot.
