Reducing run-off and soil loss are important
determinants for maintaining productivity and
sustainability on sloping agriculture lands. To control
water induced soil erosion, a field study was conducted
during 2010–2014 to assess the impact of hedge row
intercropping on soil erosion, nutrient dynamics, soil
moisture and yield of finger millet (Eleusine coracana
L.) on 5 and 10% land slope in combination with
conservation treatments. The treatment Gliricidia
? Trench planting (G ? TP) reduced run-off
by 29%, soil loss by 45–48%, and loss of soil organic
carbon (SOC), N, P and K by 42–47, 62–65, 54–58 and
51–56%, respectively over control. Similarly for
Leucaena ? Trench planting (L ? TP), the values
were 17–19, 27–40, 28–37, 42–50, 39–49, and
37–46%, respectively, over control. Reduced run-off
in the G ? TP treatment increased soil moisture
storage by 11–29%. Intensive pruning of Gliricidia
plants for 5 years yielded greater fresh leaf biomass
(12–17 Mg ha-1 year-1), whereas Leucaena yielded
only 4–5 Mg ha-1 year-1. The SOC, N, P and K
conservation efficiencies of G ? TP were 42–47,
62–64, 54–58 and 51–56% on 5 and 10% land slope,
respectively. Gliricidia hedge row intercropping
showed promise for improving the conservation
potential of the system by maintaining high productivity.
Results of this study will act as a technical
reference for the adoption of the Gliricidia based
hedge row technology for increasing intercrop productivity
as well as conserving soil resources in the
Eastern Ghats sloping agriculture lands.
