Abstract

---

Potassium (K)-ammonium () interaction for biomass production and K uptake determined by nutrient solution may be modified by soil type due to variable clay content and constituent clay minerals. Rice and wheat response to various combinations of K and was investigated in three soils in a replicated three factors factorial pot experiment. Combinations of K 0, 300 and 600 mg kg-1 and 0
