Evaluating Dripper-Plants Spacing for Improving Tomato Yield and Water Productivity under the Drip-Irrigation System in the Sudanian Climate in Burkina Faso

In Burkina Faso, surface drip irrigation is promoted as a water-saving technique to overcome the decline of agricultural water through the increase of water productivity. However, there is little proof up to now about the suitable dripper-plant spacing optimizing water uptake for high productivity....

Description
Summary:In Burkina Faso, surface drip irrigation is promoted as a water-saving technique to overcome the decline of agricultural water through the increase of water productivity. However, there is little proof up to now about the suitable dripper-plant spacing optimizing water uptake for high productivity. A field trial was undertaken to assess the effects of the dripper-plant spacing in improving yield and water productivity. The design was complete randomized blocs in four replications with the dripper-plant spacing of 0, 5, 10, and 15 cm. It is shown that placing the dripper 15 cm away from the plant resulted in higher water distribution, fruit size, and productivity. The increase of 91%, 131%, 51%, and 11% was registered for wetted area, fruit length, fruit diameter, and fruit weight, respectively. Yield and water productivity increased up to 143%. Implementing the system of drip irrigation at the dripper-plant spacing of 15 cm should be suggested for improving both yield and water productivity in the dry areas.
