Performance Evaluation Of Canal Irrigation System In Rice-Wheat Zone : Use of Geographic Information System and RS Technology for Evaluation of Canal Performance in Rice-Wheat Cropping Zone

The book evaluate the performance of canal irrigation system by using special scientific tools like Remote Sensing and Geographical Information System, so that proper measurements could be taken for the sustainable agriculture and water management. Different performance evaluation parameters had been calculated.The purposed data was gathered from field investigation and different government and private organizations. According to the calculations,organic matter ranges from 0.19% (low value) to 0.76% (high value). In comparison of flat and bed irrigation system in wheat crop,the water saving per acre varies from 46.51 to 56.5% of time. The average range of irrigation water saving at site was 51.37%, which provides evidence of 50% water saving in bed planting. Similarly, in rice crop, the range of water saving is 28.91 to 45% which happens due to over irrigation even in bed planting by same farmers. Results showed that on an average percentage yield increase in wheat bed planting fields varies from 11.83 to 29.4 % while 22.27 % increase in yield was obtained from rice bed planting in comparison with flat sowing.
