ABSTRACT

Effect of tannin substances of organic material for inhibitor nitrification on nitrogen fertilizer by
planting sweet corn. First year in clay loam at Lopburi Seed Multiplication Center, Lop Buri Province, in RCB
experimental designed was planned with 4 replications 5 treatments. The result showed chemical fertilizer
rate 20-5-5 N-P 2O 5-K 2O kg/rai mixed with ground mangosteen peel 3.22 kg /rai was highest yield followed by
chemical fertilizer rate 20-5-5 N-P 2O 5-K 2O kg/rai, chemical fertilizer rate 15-5-5 N-P 2O 5-K 2O kg/rai mixed with
ground mangosteen peel 3.22 kg /rai, chemical fertilizer rate 10-5-5 N-P 2O 5-K 2O kg/rai mixed with ground
mangosteen peel 3.22 kg /rai and chemical fertilizer rate 0-5-5 N-P 2O 5-K 2O kg/rai respectively. In sandy loam
at farmer field, Uthai Thani Province, The result showed chemical fertilizer rate 20-5-10 N-P 2O 5-K 2O kg/rai
mixed with ground mangosteen peel 3.22 kg was highest yield followed by chemical fertilizer rate 20-5-10
N-P 2O 5-K 2O kg/rai, chemical fertilizer rate 15-5-10 N-P 2O 5-K 2O kg/rai mixed with ground mangosteen peel 3.22
kg/rai, chemical fertilizer rate 10-5-10 N-P 2O 5-K 2O kg/rai mixed with ground mangosteen peel 3.22 kg/rai and
chemical fertilizer rate 0-5-10 N-P 2O 5-K 2O kg/rai respectively.
Second year in clay loam at Lopburi Seed Multiplication Center, Lop Buri Province, in Split plot in
RCB experimental designed with 3 replications was 3 main plots as ground mangosteen peel and 4 sub plots

as chemical fertilizer. The result showed main plots as ground mangosteen peel had not significantly different
by mixed with ground mangosteen peel 3.22 kg/rai was highest yield, followed by not mixed with ground
mangosteen peel and by mixed with ground mangosteen peel 15.78 kg/rai respectively. Sub plots as
chemical fertilizer had significantly different by chemical fertilizer rate 15-5-5 N-P 2O 5-K 2O kg/rai was highest
yield followed by chemical fertilizer rate 20-5-5 N-P 2O 5-K 2O kg/rai, chemical fertilizer rate 10-5-5 N-P 2O 5-K 2O
kg/rai and chemical fertilizer rate 0-5-5 N-P 2O 5-K 2O kg/rai respectively. In sandy loam at farmer field, Uthai
Thani Province. The result showed main plots as organic fertilizer had not significantly different by not mixed
with ground mangosteen peel was highest yield, followed by mixed with ground mangosteen peel 15.78
kg/rai and by mixed with ground mangosteen peel 3.22 kg/rai respectively. Sub plots as chemical fertilizer
had significantly different by chemical fertilizer rate 20-5-10 N-P 2O 5-K 2O kg/rai was highest yield followed by
chemical fertilizer rate 15-5-10 10-5-10 and 0-5-10 N-P 2O 5-K 2O kg/rai respectively.
