A split-split-plot designed pot culture experiment was conducted to evaluate the influence of phosphorus, zinc and molybdenum on nutrient and neurotoxin (13-0DAP) contents of grasspea seeds. Results showed that in most cases the higher doses (P2, Zn2 and Mo2) were statistically similar with the lower doses (P1, Zni and Moi) and the highest response was revealed with lower doses both separately and in combination of P2Zn1 and P2Zn1Mo1 in respect of protein, proline, methionine, 13-carotene, fat and 13-0DAP content.
