摘要

Chiang Mai 60, SJ 5, and Doi kham soybean varieties were grown in pots and fertilized with o, 20, 40 kg N/ha. It was found that these 3 soybean varieties gave higher seed yield with increasing of N fertilizer. The harvested seeds then were analyzed for nitrogen content using nuclear technique (neutron activation) and Standard chemical analysis. For neutron activation analysis, seeds were irradiated with fast neutron at the flux of 2.5x10~11 n.cm~-2.s~-1 from Thai Research Reactor, TRIGA Mark 3 type, at the Office of Atomic Energy for Peace.
