The soil was a silt loam with 0.93% organic C and available moisture content of 14% (wt/wt). The crop received a basal dose of 40-18-33 kg NPK/ha. Rice was sown 5 Jul 1985 in row 23 cm apart. Manure was applied at 10 t/ha. Yields were significantly higher with surface incorporation and placement at 10-cm depth. Interrow soil compaction increased yield 9%. Weed growth was reduced by about 64% in soil compacted plots. Surface layer soil moisture retention was increased by soil compaction and FYM placement. Profile moisture in the compacted plots was about 2 cm higher than in the uncompacted plots.
