Improving Water Application Efficiency of Irrigation Borders Using Modified Water Front Advance-time Relation
Prabeer Kumar Parhi

Abstract:
Background and Objective: Border strip method of irrigation is a widely used surface irrigation technique which is best adapted to crops like wheat, barley, fodder crops and legumes. The present study was aimed to design an irrigation border to maximize water application efficiency which is very important to meet the growing water needs. Materials and Methods: Using the modified water front advance-time relation, an irrigation border has been designed and its efficiency was evaluated. The derived design procedure ensured application of uniform depth of irrigation throughout the length of border thus maximizing water application efficiency of the irrigation borders. In the present study the required optimum border length, entrance stream size and the corresponding Manning’s ‘n’ had been derived to achieve optimum irrigation water application efficiency. The derived design procedure has been applied to the wheat crop cultivated in sandy loam soil in the Ramiala irrigation command (Orissa, India) to determine entrance stream size and corresponding optimum border length. Results: The result of the study showed that the optimum border length and entrance stream size required are, respectively 40 m and 2906 cm3 min–1 cm–1 which gives maximum water application efficiency up to the tune of 83.32%. Conclusion: The modified design technique increases the water application efficiency of the irrigation borders, which appears very high as compared to the achieved efficiency of 66.5%, as available in the literature. The suggested method appears very simple and can be applied easily to crops having different root zone depths cultivated in different soils.
