Abstract

The effect of different levels of N, P, and K with and without Ca, Mg and two levels of calcium silicate, was studied on Kaki pigeonpea in an Oxisol at the Isabela Experiment Substation. The study confirmed previous results showing that fertilizer treatments have no effect on green pod yield, date of flowering, plant height, seed weight or protein content of the dry seed.
