| Abstract | ||
| This experiment was conducted on the field of the College of Agriculture /University of Baghdad by using drip irrigation and comparing it with normal irrigation .six pipes of 20 cm diameter ,6 m long were used . They were punched from the top with 10cm diameter hole along the pipe, the total amount of the holes are 28 for each pipe and the distance between each hole is 10 cm . These pipes were marked as A1,A2,A3 filled with sand soil , pipes B1,B2,B3 filled with sand soil mixed with pitmos with 1:4 .Four grooves have been dogged with the same length and number of holes in the pipe ,the grooves marked as C1,C3 with sand soil ,while C2,C4 with sand soil mixed with Pitmos . The pipes and grooves were planted with bean seeds .Time of irrigation had been changed as follows : A1,B1C1,C2 were irrigated every 4 days with 14 Liters by using drip irrigation , A2,B2, irrigated every 6 days with 14 liters by using drip irrigation while A3,B3 were irrigated every 7 days with 14 Liters by using drip irrigation and C3,C4 were irrigated every 2 days with 75 Liters by using normal irrigation . Randomized Complete block Design with three replications and LSD (0.05) was used to compare the means of treatment at 0.05 level . The results showed that .In the first week noted that germination percentages in ,C1,A1,A2,A3,C3 were better than in C2,C4,B1,B2,B3..In the second week the length of plants were the same in all pipes and grooves ,while the growth in C1 was too weak compared with C2 ,until the plants died in C1 .In the third week I noted that the growth of the plants in B1,C3,C4Was higher than the others,while the plants were died in C2, showed planting in the PVC pipes with using drip irrigation achieved lower water consumption and better growth . | ||
