ESTIMASI KEBUTUHAN AIR IRIGASI PADI (Oryza sativa L.) DI DESA KOTO PERAMBAHAN KECAMATAN KAMPAR TIMUR BERDASARKAN MODEL SOFTWARE CROPWAT 8.0

Water availability is one of important factor to assure that a field could support increassing rice production value. These descriptive quantitative research aimed to get schedule and amount for irrigation water requirement based on climatic data, soil and crop. Data collected for these research were temperature, humidity, sunshine hours, wind speed, rainfall, plant morphology, altitude and latitude. The research was conducted on July until August 2019. Soil samples was carried out from field area in Koto Perambahan village, East Kampar sub district using purposive sampling method. Data was processed by Cropwat 8.0 software to get amount water requirement for replace the water losss caused of evapotranspiration. Based on weather condition, the field is suitable to plant rice in two season. Irrigation water requirement was writed in decade form, it means for ten days. First planting season occurred on March and irrigation water requirement was 180,6 mm/dec. Second planting season should be done on October with irrigation water requirement was 167,2 mm/dec. The highest irrigation water requirement was estimated on nursery stage, exactly in formation of rice tillers with approximately values 98 mm/dec.

Climate change has seriously impacted water availability and agriculture production in arid and semi-arid climates. Estimation of actual crop evapotranspiration (ETa) is critical for agricultural water resource management and proper irrigation scheduling. This study aimed to (1) estimate the reference evapotranspiration (ETo) and four vegetables actual ETa during crop off season using Penman–Monteith method and alternative climatic data models and, (2) to determine the irrigation water requirement for these main vegetable crops in northern Togo. Four (4) ground based weather stations were considered across the northern region of Togo for 1987 - 2016 period. Non parametric Mann-Kendall test was used for the significance of the trend analysis of off season reference and actual evapotranspiration. The results showed a decreasing trend in off season ETo at Dapaong, Mango and Kara weather stations while Niamtougou showed an increasing trend in the long term ETo. From all stations, only Niamtougou had a significant increasing trend in ETa for all vegetable crops under this study. Among the study locations, Mango had the highest irrigation water requirement for all four vegetable crops, followed by Kara. The lowest irrigation requirement was obtained at Dapaong. These results will help in irrigation planning for tomato, cabbage, carrot and onion in the semi-arid climate of Togo and similar environment.

Dry Areas

The rapid increase of desertification’s degradation is one of the worst environmental and economic threats for dry areas. Climate changes, very year impacts thousands of areas across the globe. The high cost of electricity and diesel-based fuel affects photovoltaic water pumping requirements for irrigation in many parts of the world. Solar irradiance in every dry place is extremely high due the drought increase. Thus, using solar energy for water pumping is a promising alternative sources of energy. Undertaking irrigation for a particular place and crop requires not only skills in the irrigation planning but also in the power requirement of the entire system. A reliable and accurate estimation of ET rate and irrigation water requirement (IWR) are soundly important in irrigation field. This sought to accurately estimate the irrigation power requirement by using PVsyst software on nine different pumps technologies combinations with different type of converters at 100m, 150m, 180m, and 200m of Total dynamic Head (TDH). The study has been conducted in four sections, the first section dealt with the assessment of the collected data, the second section with the simulations, the third one with the irrigation water requirement and finally irrigation water requirement. The results found in study show that IPR of a crop is majorly depend on the TDH. Among the nine combinations, results show that the Maximum Power Point Tracking (MPPT) technology is the best in terms of power requirement of selected the crop. Furthermore, the maximum and minimum values of the irrigation water requirement for millet crop was found to be 12.9 mm/day and 4.9mm/day respectively.
