Effect of various tillage practices on soil Physical properties,
root growth and yield of wheat - maize rotation were studied during
1996 - 99 at NWFP Agricultural University Research Farm, Peshawar,
Pakistan. Tillage implements were used in the experiments moldboard
plow, disk plow, disk harrow, rotavator and cultivator. Lowest
average bulk density and soil strength of 1.46, 1.57 g/cm3 and
62.9, 121 N/cm2 respectively were recorded in deep tillage plots
while the highest of 1.52, 1.62 g/cm3 and 75.6, 140.7 N/cm2
respectively were found in shallow tillage plots for two depths
(i.e. 0 - 21 and 22 - 42 cm). Significantly higher root length and
dry root weight of wheat were found in deep tillage (moldboard plow
and rotavator once, M1R1) and the minimum root length and dry root
weight were recorded in the shallow tillage (C2). Highest grain
yield of wheat and maize (4422 and 4827 kg/ha) were found in the
deep tillage (M1R1) while the lowest (3806 and 3966 kg/ha) were
noted in the shallow tillage (C2). In general, deep tillage
improved the soil physical conditions. Therefore, it is recommended
for optimum yield of wheat and maize under irrigated clay loam soil
condition.
