By using different ridge and furrow micro catchment water harvesting techniques which were determined that rainfall is dropped from ridges into furrows are increased soil water content and are improved yield, crop water productivity and plant growth parameters. In this study, the effects of ridge widths-plant rows, soil water content, conapy- ambient air temperature difference, canopy, ambient air and soil temperature were evaluated on red pepper plant height which using 3D models. Soil water content was obtained highest for ridge-furrow rain water harvesting treatments (RWHS) with respect to dry farming treatments (DFS) and it was affected plant growth. The significant interactive relationship were obtained between soil water content and ridge widths-plant rows and canopy-ambient air temperature difference and canopy temperature were affected on plant height linearly for RWHS and DFS. The significant interactive linearly were found ambient air and soil temperature, canopy and soil temperature to affected on plant height, respectively. Plant height can be predicted to using these models which was found high determination coefficients.
