Abstract
Two field experiments were carried out during the two successive summer growing seasons of 2009 and 2010 at Kaha Research farm, Kaluobia Governorate Egypt. Jerusalem artichoke (Helianthus tuberoses L) 'Fuseau' cultivar was used for studying the effect of irrigation intervals (every10, 15 and 20 day) and different cutting times (at 60 and 90 days and control, i.e., without cutting) on Jerusalem artichoke tuber yield and water productivity. A split plot design was used. The results indicated that yield and its component of Jerusalem artichoke, i.e., the total and marketable yield of tuber /fed, average of tuber yield /plant and average fresh weight of tuber were increased with applied irrigation every 10 day (3661 m3) and plants without top cutting. On the other hand, dry matter content in leaves and tuber, total carbohydrates in leaves and crude fibers, inulin content in tuber were not affected by applied irrigation intervals. Total protein content in leaves was increased with applied irrigation up to 3450 m3/fed., while the same applied quantity of water reduced total crude fiber content in leaves. Dry matter, crude fibers and total carbohydrates contents of leaves were significantly increased in plants cut their top at 90 days after planting, while total protein content in leaves and total sugar in tuber significantly increased in plants without cutting (control). The results also indicated that inulin ,dry matter and crude fibers content in tuber were not significantly affected by cutting age treatments.The interaction between irrigation intervals and cutting times showed that the maximum values of the total, marketable tuber yield/fed. And average tuber weight were obtained due to irrigation interval every 15 day for the control plants (without cutting). The interaction between irrigation interval every 15 day and cutting plant at 90 day after planting gave the highest values of inulin and total sugar content in tuber, and dry matter content in leaves. Meanwhile plants subjected to cutting at 90 day after planting and supplied water irrigation intervals every 20 day increased significantly in crude fibers and total carbohydrates in leaves.The number of applied irrigations and water consumptive use (CU) were increased as the shortage of irrigation times and Cu differed significantly due to cutting ages, where cutting2 consumed more water than the other cutting times. The highest Water Use Efficiency (WUE) was recorded under 10 days intervals comparable to the other tested irrigation frequency and values of WUE differed due to cutting times; where the cutting2 gave the lowest WUE, while both of cutting1 and control gave the highest value for the first and second growing season. On other hand, results showed that the most efficient and relevant mathematic method in calculating ET crop for Jerusalem artichoke in south Delta of Egypt (El- Kanater) region was Modified Penman formula.
