Studies on the effect of plant nutrients on turmeric production, the experiment was conducted at Nakorn Nayok Province during 2009 with RCBD design for 4 replications and 5 treatments namely: 1) untreated check 2) farm manure at 12 kg N/rai 3) farm manure at 12 kg N/rai plus chemical fertilizer at 5-5-5 (N-P 2 O 5 -K 2 O) kg/rai 4) farm manure at 12 kg N/rai plus chemical fertilizer at 10-5-5 (N-P 2 O 5 -K 2 O) kg/rai 5) chemical fertilizer at 10-5-5 (N-P 2 O 5 -K 2 O) kg/rai.

The results showed that effect of plant nutrition to yield was significant. Untreated check (1,242 kg/rai) was provided lowest yield, while as, fertilizer using provided higher yield (2260.22 kg/rai). The combination of farm manure and chemical fertilizer trended to have higher yield than the single treatment. The curcuminoids and volatile oil contained in turmeric were more than 5% curcuminoids and 6% volatile oil, which were met to standard level and no significantly different in amounts of active constituents on any treatment.
