Assessment of Water Application Losses through Irrigation Surveys: A Case Study of Mirpurkhas Subdivision, Jamrao Irrigation Scheme, Sindh, Pakistan

Water loss from furrows can be due to runoff, seepage and deep percolation which may cause yield reduction. This study focuses on the evaluation of irrigation water application techniques and employed experimental observation which included 30 test observations using the bund, cut-off, cut-back, surge, and portable structure techniques. The experiments were carried out in two blocks; block A with 50 m furrow length and that of block B with 100 m furrow length. The experimental design was a randomized complete block design with three replications. The analysis was done using surface irrigation evaluation model and SAS software package. The results of the study showed that at block A, highest application efficiency of 87.0% was obtained with surge flow and followed to this cut-back recorded 86.6%; whereas the lowest application efficiency of 75.00% was obtain by bund technique. Storage efficiency of surge and cut-back recorded 99.00%. The lowest was obtained by bund (88.9%). The distribution uniformity of surge was highest (84.1%). whereas bund technique gave 71.0% of lowest distribution efficiency. At block B, surge registered the highest application efficiency and distribution uniformity of 66.0% and 59.57% whereas; bund technique records the lowest application efficiency of 60%. The surge and cut-back were more efficient in the field recovery of storage requirement resulted above 99.0%. The statistical analyzed results showed that mean application efficiency of 75.69% was obtained using the surge technique; whereas the lowest application efficiency of 70.0% was obtained by the bund. The use of the surge technique reduces irrigation water loss from 30.0% to 24.3% compared to the local bund technique. This is due to the surge performed better in terms of advance rate and efficient moisture content. With the surge, the highest mean DU of 68.07 % was obtained, while the bund technique had the lowest DU (58.32%). Therefore, adoption of the surge is a promising water application and management practice in sugar cane plantation at Omo Kuraz.

“…Abbasi et al [14] studied irrigation efficiency in Iran from 1991 to 2015, and the results showed an increase in irrigation efficiency in recent decades due to improved knowledge of users about water and soil problems and the use of modern irrigation systems. Shaikh et al [15] studied losses assessment of Irrigation Applications in the Jamrao irrigation Scheme, Sindh, Pakistan. Field measurements were carried out on 20 farms for moisture content before and after irrigation.…”

An evaluation the performance of the irrigation system for the Al-Ishaqi irrigation project for the Eastern Canal was conducted to identify management strategies that can be used to improve the operation and performance of the irrigation system. The study area is located in Salah al-Din G.0overnorate, Iraq. The field work included determining the moisture content of the soil before and after irrigation, measuring the inflow of the field to find the depth of the applied water, field monitoring, and measuring the depth of the root zone for each irrigation process. Field measurements showed that the average efficiency of water application for the two fields (A, and B) are 59.81% and 38.6%, respectively. The results of the efficiency of water application showed that farmers use water more than the actual demand, so it was possible to increase the efficiency of field water use by controlling the quantities of water that supplied and controlling the irrigation time and water distribution within the irrigated land. The results also showed that the storage efficiency of the two fields (A, and B) ranged between (39.1% to 68.28%), and (41.80% to 79.8%), respectively. As for the efficiency of water distribution, the average distribution efficiency for fields (A) and (B) was about (99.54%) and (99.33%), respectively. The irrigation efficiency evaluation done in the Al-Ishaqi Irrigation Project revealed that farmers utilize more water than is required, resulting in a substantial amount of water being lost in the fields observed in this research owing to inefficient use. If the current scenario continues, groundwater levels would undoubtedly rise, putting the irrigation system's long-term viability in jeopardy.

“…In irrigated agriculture, the efficiency of applying water is a burning issue as water resources become increasingly scarce due to climate changes. As demonstrated by IQBAL et al [1994], the measurement of water application efficiency requires irrigation advance data for volume analysis and hydrodynamic models or moisture calculations pre and post irrigation for which different methods are used [SHAIKH et al 2017]. In other words, the water application efficiency measurement is based on the quantity of water stored in a root zone and water that is used by plants.…”

In furrow irrigation, the maximum lateral movement of water in ridges is more desirable than the vertical downward movement. This can be achieved by compacting the furrows. Thus, the study examines the impact on furrow soil compaction by tractor wheel trafficking during mechanical operations in the different soil types. In this experiment, the three-wheel tractor compaction includes: 1) control (no soil compaction), 2) compaction through 3-wheel tractor passes, and 3) compaction through 6-wheel passes under three different soil textural classes such as: clay loam, silty clay loam and silty loam soils. The impact of various treatments on clay loam, silty clay loam, and silty loam under 3-and 6-wheel passes showed increased bulk density (7-12%), field capacity (9-19%), ridge storage efficiency (35-38%), water use efficiency (16-20.5%) and decreased soil porosity (7-16%), infiltration (8-20%), and furrow storage efficiency (28-41%) over the control. This study shows comparable results of 6-passes with other studies in which more than 6-passes were used to compact the soil. This study suggested that farmers can maximise water use efficiency by compacting their furrows using 6-passes tractor trafficking.
