Abstract

Drip irrigation system is the efficient method of vegetable crop irrigation. This investigation is made to study water distribution horizontally and vertically in the root zone of radish crop. This study is also about leaching water below the root zone with using the modeling approach in the crop root zone. In this research laboratory and field data are used by HYDRUS-2D model. It is a high capability SIMULATION model. Results of modeling indicated that with choice of suitable irrigation cycle (48 hour here) and emitter discharge, soil moisture is maintained at field capacity level during the whole cropping season and it decreases very slowly and supplies the required moisture for the crop. The results of water leaching and infiltration showed that leaching water below the root zone from drainage boundary compared to the total volume of water applied for the whole growing season is very low. Volume of drainage water is 0.05% of the total water used which is negligible.
