A filed study was conducted to determine the effect of tillage practices and compaction on infiltration rate of a sandy soil. Mean cumulative infiltration ranged from 3.18-6.15 cm hr-1 for rotavator, 3.75-7.85 ca hr-1 for moldboard plow and 6.02-13.62 cm hr-1 for chisel plow under different compaction treatments. Whereas, mean infiltration rate of soil was 6.53 cm hr-1 for rotavator, 7.59 cm hr-1 for moldboard plow and 12.36 cm hr-1 for chisel plow. Among the various compaction treatments. three-pass treatment caused 12.5, 22.9 and 50.3% reduction in infiltration rate of soils under rotavator, moldboard and chisel plow, respectively. However, the reduction in infiltration rate of soil under high compaction treatment (five-passes) was 35, 45 and 58% under rotavator, moldboard and chisel plow, respectively. The difference in infiltration rate of soil was significant among on pass, three pass and five- pass treatments than the control treatment (zero-pass). This study has highlighted on-pass, three-pass and five-pass treatments than the control treatment (zero-pass). This study has highlighted an excellent potential for water conservation in sandy soils if simple conventional agricultural implements such as tractor,planters etc. alongwith different tillage practices are used for soil compaction.
