A technical report was conducted for checking performance assessment of drip irrigation system which was used for cultivating tomato in premises of the Centre of Excellence Protected Cultivation, Raipur (Chhattisgarh). A uniformity coefficient was found for drip irrigation system which ranges from 73.2 % to 83.6%. The coefficient of variance varies between 0.0055 to 0.0068 for the measured discharges of four laterals laid in the field. It shows that there is the least variation between the obtained flow rates of different laterals under study. The application efficiency of four different lateral lines operating at a pressure of 1.25 kg/cm2 was calculated and it found to be more than 90.00 %, excluding lateral line (L2). Almost same amount of flow variation (8-9%) is found in lateral lines L1, L3 and L4, although Lateral line (L2) discharges 11.00 % more water among others. The maximum flow variation was found for the lateral line (L3) and the least flow variation was for the lateral line (L1). The distribution efficiency of all the laterals was found more than 97.45 %.

In the agriculture field, the method of irrigation and its proper usage is more important and it is well known that a very economical and efficient method is drip irrigation. The continuous monitoring of the soil and weather condition has to be done by the farmer in favour of growth of crops in conventional drip irrigation system. In this proposed system, the soil and weather condition of the field are monitored by the moisture as well as temperature sensor. The values from the temperature and moisture sensors are sensed and the signal is sent to the Arduino IDE controller which is powered by solar energy and thus the present values are compared with predefined values. According to value of the temperature and moisture, the crops can be supplied with the required amount of water. In the liquid crystal display, the sensed values of the temperature and moisture will be displayed and the user can receive the data through the GSM module.

A field experiment was carried out in the field of the College of Agriculture / University of Wasit, located on longitude  45o   50o   33.5o   East and latitude 32o 29o 49.8o North, in Spring season of the agricultural season 2019, in order to estimate the water consumption of potato crop using SWRT technology and under the drip irrigation system. The experiment was designed according to Randomized Complete Block Design (RCBD) with three replications and four treatments that include of the SWRT treatment (the use of plastic films under the plant root area in an engineering style), and the treatment of vegetal fertilizer (using Petmos), organic fertilizer (sheep manure), and the control treatment . Potato tubers (Solanum tuberosum L.)  var. Burin was planted for spring season on 10/2/2019 at the soil depth of 5-10 cm. The highest reference water consumption for the potato crop during the season was calculated by Najeeb Kharufa, which was 663.03 mm. The highest actual water consumption for the potato crop during the season for the control treatment was 410.1 mm. The results showed increase in the values of the crop coefficient (Kc) in the stages of tubers formation and tubers filling stage as compared to the vegetative and ripening stages, ranged from 1.37-1.92 for the two stages of tubers formation and tubers filling. The SWRT treatment gave the highest water use efficiency during the season, was 3.46 kg m-3 .
