Abstract
A study was conducted to determine the effect of tillage, namely, no-tillage (NT), slashing (SH), ploughing (PHO), ploughing plus harrowing (PHA), ploughing plus harrowing plus bedding (PHB), on soil physical properties, growth and shoot yield of large-green leafy amaranth (Amaranth sp.). Soil moisture retention and infiltration rates were also measured in two cropping seasons. Soil moisture retention did not reflect any significant differences in the first and second season at 0-10 cm depth. However, at 10-20 cm depth, PHA treatment gave the highest values at all the suction points (P
