| Summary: | The purpose of this study is to know the quantitative changes in the
physical properties of soil as a result from differences soil tillage methods on
soybean planting in rice field after rice planting. The experiments were conducted
in a randomized complete block design ( RCBD ) in KP4 UGM. Three kinds of
treatments are no-tillage (A), once hoe (B) and twice hoe (C) and each treatment
was repeated three times .
Result of this experiment showed that by once hoe lowering bulk density
values by 31 % and increase soil porosity up to 66%, while for twice hoe
lowering bulk density values by 36% and increase soil porosity up to 65%. No �
tillage treatment retain available moisture better than once hoe and twice hoe
treatment. Total yield of soybean in no � tillage treatment didn�t have
significantly different with once and twice hoe treatment. |
