Abstract: The present experiment was conducted to study the evaluate the performance of developed soil moisture sensor based automated drip irrigation system for cabbage crop. The study involve to setup the develop soil moisture sensor system for real time monitoring of soil moisture content and its calibration along with gravity operated drip irrigation system for cabbage. The Automatic drip irrigation system will supply water to the plant as soon as they need it and is calibrated to maintain the soil moisture regime which helps in increasing crop yield, saving of precious water, energy and labour costs as compared to manually operated system. The aim of this research work was to come up with a solution to solve the problem of scarcity of water, maximizing crop profit by timely irrigation. xi The experimental field with an area of 600 sq m was set up at the farm of Krishi Vigyan Kendra, IGKV, Raipur. The experiment of automated drip irrigation was carried out on cabbage crop of golden acre variety. The row to row spacing and plant to plant spacing was 90 cm and 60 cm respectively. Laboratory test of the field’s soil sample revealed its texture as sandy clay, bulk density (1.33g cc-1) and field capacity (32%). Soil moisture sensor system was calibrated in such a way that the system starts automatically when soil moisture deplete by 50% and replenish the moisture regime till 80% of field capacity. Gravity fed drip irrigation contains overhead tank capacity of 1000 l (tank height 1.18 m) with total delivery head of 6.18 m. The maximum horizontal and vertical wetting front advance of 2 l discharge of emitter at 0.5 kg/cm2 was recorded as 4.0, 8.0, 12.3, 17.0 cm and 7.5, 12.5, 21.0, 24.0 cm respectively after elapsed time of 15, 30, 60 and 90 min. The hydraulic performance of the currently started drip irrigation system was tested and it was found that the average discharge of emitter is 1.08 l h-1 (in-line emitter) and it was tested at different points (10 m distance) at 10 min interval of different operating head, Emission uniformity (98.80%), Uniformity coefficient (98.45%), Distribution efficiency (96.55%) and Application efficiency (98.91 %) were found operating head 6.18 m to 5.94 m. The growth parameter recorded under sensor based treatment the maximum plant height was 36 cm, maximum plant spread was 44.27 cm, maximum number of unfolded leaves per plant was 16, fresh avg. weight of head 1.56, maximum root length 24.1 cm, yield per hectare of sensor based irrigation was 19.5 t ha-1 and on the other hand control based irrigation yield per hectare of 16.87 t ha-1 was obtained. Water Use Efficiency of 73.4 kg ha-1 mm-1 was found under sensor based treatment where as the control drip irrigation was found to be 57.13 kg ha-1 mm-1.
