Abstract
The present investigation was carried out with the objective to access the effect of subsoil compaction and slope steepness on soil physical properties, plant growth, yield s and yield attributes of maize. The results revealed that the subsoil compaction significantly affected the bulk density, total porosity, infiltration rate and cumulative infiltration. However slope steepness did not shown significant effect on all these physical properties. The plant height, yield and cob length was significantly higher under lower level of subsoil compaction than that in higher degree of subsoil compaction, while cob barrenness and crop lodging was more under higher degree of subsoil compaction. The slope steepness significantly improved the grain yield and biological yield of maize by reducing the crop lodging as a result of high intensity rainstorm occurred during summer monsoon season. This study will encourage the fine tuning of existing technology to improve the crop yield under compacted subsoil conditions especially under rice-wheat cropping sequence.
