A field experiment was conducted in the research farms of Irrigation Water Management Research Center (IWMRC), Belvatagi, University of Agricultural Sciences (UAS) Dharwad during Rabi 2019 to study the effect of field topographic conditions on plant height of Rabi Sorghum in vertisols under rainfed situation. Grid survey (10 m X10 m) results in traditionally levelled field indicated that the average reduced level (RL) of field was 98.46 m with range of elevations 98.13 m to 98.80 m and standard deviation of grid elevations of 14.36 cm. The standard deviation of grid elevations (14.36 cm) and 3-D contours indicated more undulations in topographic conditions. The average grid-wise plant height of Rabi sorghum was 1.59 m with range of grid - wise average plant heights varying from 1.34 m to 1.81 m with standard deviation of 9.8 cm. It was found that variability of topographic conditions of the field resulted into variability in plant heights of Rabi sorghum. This calls for better land levelling methods to achieve more uniformity in the plant heights which would help in achieving uniform and higher crop yields.
