<abstract><p>The aim of this study was to conduct a performance evaluation of drip irrigation system on carrot production at IPRC Gishari farm in Rwanda. The Coefficient of Uniformity (CU) and Emission Uniformity (EU) were computed. The SPSS 22.0, STATA 13.0 and Ms Excel computer packages were used to perform ANOVA one way for soil physical and chemical properties change along the experimental site T-test for significance parameters while conducting the leaching experiment of the soil. The findings showed that the highest rainfall of 94.6 mm was received during the month of March with average precipitation of 123.14mm. The average minimum temperature fluctuates between 15.28 ºC to 13.22 ºC recorded in the months of February and July. The maximum temperature variation was ranging between 24.99ºC as the lowest and 26.9ºC as the highest average maximum recorded in May and September. The percentage of relative humidity was in range of 79.63% and 60.53% recorded in months of April and August. The highest wind speed was recorded in the months of August and September with 127.98Km/h and 124.88Km/h followed by 121.76Km/h recorded in July. For soil properties (physical and chemical), the results showed that the average values of sand, silt and clay among the three plots were 68%, 22% and 9% for the whole experimented farm under drip irrigation system for carrot production and the soil is classified as sandy loam soil. It was also found out that the overall bulk density of the soil was found to be 0.818 gm/cm3. The average soil porosity was also found to be 12.32%. It was found that the MC from the all plots varies from 16.5% to 58.8% while the average mean MC was found to be 37.25% of H2O was removed. The study findings showed that SOM for all experimental plots varies from 10.92% to 50.54% while the overall average mean SOM was found to be 24.94%. It was found that the calcium (Ca) content was at 0.901 ppm, its range varies from 0.716 ppm to 1.103 ppm. It was found that Magnesium content was at 1.59 ppm, its range varies from 0.292 ppm to 2.496 ppm. It was found that the Sodium (Na) content was at 1.047 ppm, its range varies from 0.758 ppm to 1.227 ppm. It was found that Potassium (K) content was at 0.801 ppm, its range varies from 0.371 ppm to 1.271 ppm. It was found that the Nitrogen (N) content was at 1.771 ppm, its range varies from 0.749 ppm to 2.835ppm. It was found that the pH value was 6.9, its range varies from 6.3 to 7.3 which is acidic soil. It was found that the EC (µS/cm) value was 74.11 µS/cm, its range varies from 66.17 µS/cm to 92.56 µS/cm which is saline soil. It was found that the SAR was 0.341which is lower and its range varies from 0.248 to 0.52. The study findings showed that the monthly average mean of solar radiation was 34.9 MJ/m²/day while its range varies from 32.2 MJ/m²/day to 37.5 MJ/m²/day. It was found that also that the mean ETo from the experimental site was found to be 5.94 mm/day. It was also found out that the Net Irrigation Water Requirement (NIWR) was found to be 3,557.3m3/ha which is very low compared to Gross Irrigation Water Requirement (GIWR). The study findings also showed that the average mean of CU was found to be 83.5% while its range varies from 49% to 99.7%. The total productivity of carrot under the area of 0.768ha was found to be 3816.83Kg or 3.82tons. The study findings recommends that University of Rwanda (UR) and College of Agriculture, Animal Sciences and Veterinary Medicines (CAVM) should equip soil and water laboratories with all necessary basics tools and machines, regents and other chemicals through reduction of tender process and other unnecessary logistics regarding to Soil laboratory services.</p></abstract>
