Abstract

A Self-propelled planting machine was developed to be suitable for lands in which sub surface drip irrigation system is applied.
The developed machine was investigated during planting corn seeds as a function of change in both sub surface irrigation parameters ( two different lateral line depths and two distances between emitters in the lateral line) and machine operating parameters( three different forward speeds and two distances between plants in the row).
The sub surface drip irrigation system was evaluated in terms of soil moisture content and water distribution uniformity.
The developed planting machine was evaluated comparing with the manual method in terms of emergence ratio, longitudinal dispersion, energy requirements, crop yield and planting cost.
The experimental results reveal to the following:
- for sub surface irrigation parameters:
Lateral line depth of 30 cm with three emitters per meter were considered optimum values to achieve high uniformity of water distribution and high water use efficiency.
-        for machine parameters:
-        Machine forward speed of 3.2 km/h with 30 cm distance between plants in the row were prefered to achieve high crop yield and low planting cost.
