Abstract<\/strong><\/p>\n\n\n\n

An experiment\nwas conducted at Northern Highlands Agricultural Research Regional Station in\nSana’a, Yemen, to simulate distribution of soil moisture under alternative\nfurrow irrigation, and soil water balance. Six treatments applied, namely:\nEFI1, EFI2, EFI3, AFI1, AFI2 and AFI3; which EFI means conventional (or full)\nfurrow irrigation, and AFI alternative furrow irrigation, and the numbers 1,2,3\nrelated to levels of irrigation water 100%, 75% and 50% respectively, which the\ntreatment EFI1 was the farmer practice. VS2DI model was used to simulate water\nmovement in soil for all treatments. EFI1 treatment used for calibration\nprocess to calibrate some parameters related to soil and transpiration, and the\nrest 5 treatments for verification. Results showed that there was satisfactory\nagreement between measured and estimated soil water content, and there was goodness\nof fit in the statistical values of (R2<\/sup>), (RMSE), and (D) in all\ncases. The results also showed that the pattern of soil moisture distribution\nplays an important role in benefit of alternative furrow irrigation over\nconventional irrigation, which has been found that the soil moisture in parts\nof soil profile (under irrigated furrow) maintain high, and suitable for plant\nin AFI treatments compared with EFI at the same level of irrigation water,\ngenerally compared with AFI, the deep percolation was higher in EFI, the\ncumulative evaporation and transpiration didn’t affected by irrigation method,\nbut the evaporation and transpiration rates are affected; In the first stages\nafter irrigation the evaporation and transpiration rates was higher in EFI than\nAFI, and vice versa in the late stages after irrigation, then at a certain time\nafter irrigation, the transpiration rate dramatically decreased in EFI, but\nthat wasn’t noticeable effect in AFI; this explain the slightly effects on\nyield in AFI with decrease in irrigation water compared with EFI. The study\nconcluded that another studies concerned in the physiological response of plant\nin transpiration to partial root zone drying and soil moisture distribution\nmust be conducted, and the root activity function must be improved in VS2D\nmodel. Also concluded that the AFI technique is practicable and useful in arid\nareas where the water is cost.<\/p>\n\n\n\n
