Potash nutrition of tapioca (Manihot esculenta Crantz.)

Abstract

An investigation was undertaken at the College of Agriculture, Vellayani and Rice Research Station, Kayamkulam for two years during 1977-79 to study the performance of tapioca (Var. Sree Sahya) under two different agroclimatic conditions. The treatments consisted of three levels of nitrogen (50, 125 and 200 kg N/ha) and three levels of potassium (50,125 and 200 kg K2O/ha) at three times of application. The experiment was laid out in a 3 partially confounded factorial design with two replications.
