An experiment under rainfed condition was conducted in the farmer's field in the
Nilgiris, the North-Western part of Tamil Nadu for evaluating the influence of
conservation practices on soil moisture and plant growth under new tea
plantation. One year old B-6 tea clones were planted at double hedge spacing (135
x 75 x 75 cm) in two slopes (8-12 and 30-35%) with treatments viz., contour
staggered trenches (CST) in the walking rows (space between pairs of tea rows),
vegetative barrier (VB) of geranium in walking rows, CST and VB of geranium in
alternate walking rows, CST with cover crop of beans as well as in control
condition. Minimum runoff in CST with cover crop followed by CST and CST
with VB in both the slopes proved the cause of CST either alone or in
combination in reducing runoff. Runoff retention in the trenches attributed to
higher soil moisture in CST (25.6%) and CST with cover crop (24.8% ) followed
by CST with VB (22.8%) in 8-12% slope with similar trend as well in 30-35%
slope during non-monsoon period. Tea canopy followed a similar trend to that of
soil moisture content with maximum (39.5%) in the CST with cover crop
followed by CST (38.4%) and minimum in control just before the first harvest in
8-12% slope. The maximum plant height obtained in CST with cover crop
followed by CST may be due to similar reason as in canopy development. Higher
yield from all the conservation practices over control (3.8 t ha -1) with maximum in
-CST with cover crop (4.7 t ha-1 ) followed by CST (4.4 t ha-1 ) in 8-12% slope was
due to better growth resulting from higher soil moisture.
