Abstract: The experiment was conducted to evaluate the effect of irrigation systems, planting methods and irrigation intervals on soil porosity and soil electrical conductivity and potato yields for fall season of 2016 in Yousufia Area. Three irrigation systems included Sprinkler Irrigation (S), Drip irrigation (D),and Furrow Irrigation (F), two different irrigation intervals included (4 day irrigation interval (I1) and 8 day irrigation interval (I2)) and two methods of planting included (Mechanical planting (M) and Manual (Hand) planting (H) were used in the experiment. Soil Porosity, electrical conductivity of a saturated soil extract (Ece), average weight of potato tuber, and plant yield were measured in this study. Split split plots arrangment under Randomized Complete Block Design (RCBD) with three replicates, were used in this experiment. The means of treatments were compared by using least significant difference (LSD=0.05) under probability of 0.05. The results can be summarized as follows: 1- Drip irrigation was superior in obtaining the least value of the electrical conductivity stood 2.76 ds.m-1, highest potato yield stood 811 gm. plantˉ¹ and highest value for the average weight of potato tuber was 150 gm. Also, the furrow irrigation treatment was superior in obtaining the highest value of soil porosity stood, 0.44 cm3.cm-3. 2- 4 days irrigation interval got a significant higher single plant yield stood 731 gm.plant-1, and potato tuber weight average stood 117.83 gm and got the least value of electrical conductivity stood 3.40 ds.m-1, whereas 8 days irrigation interval was superior in getting the highest value of porosity, stood 0.40 cm3.cm-3. 3- Mechanical planting method resulted in obtaining the highest value of porosity, stood 0.40 cm3.cm-3, and the highest yield for a single plant value stood 703 gm.plant-1, and the highest value of potato tuber average weight stood 131.33 gm. 4- The interaction between drip irrigation and 4 days irrigation interval was superior compared to other interactions in obtaining the least value of the electrical conductivity (Ece) stood 2.52 ds.m-1, and highest value of single plant yield stood 884 gm.plant-1, and highest value for the average weight of potato tuber stood 161.17 gm. On the other hand, the interaction between furrow irrigation method and the 8 days irrigation interval in obtaining the highest value for porosity which stood 0.44 cm3.cm-3. 5- The interaction between drip irrigation method and mechanical planting method was superior compared to other interactions in obtaining the highest yield value for single plant which stood 846 gm.plant-1, and the highest value for the weight average of potato tuber stood 157.50 gm. while, the interaction between furrow irrigation method and mechanical planting recorded the highest value for porosity which stood 0.46 cm3.cm-3. 6- The interaction between 4 days irrigation interval and mechanical planting showed a superiority in obtaining the highest value for single plant yield which stood 770 gm.plant-1, and highest value for the weight average for potato tuber stood 140.44 gm, compared to other interactions, and the interaction between 8days irrigation interval and mechanical planting method was superior to obtain the highest value of porosity stood 0.42 cm3.cm-3. Also, the interaction between 4 days irrigation interval and the manual (hand) planting methods was superior to obtain the least value for electrical conductivity for soil solution stood 3.34 ds.m-1. 7- The triple interaction between drip irrigation, 4 days irrigation interval, and mechanical planting method was superior in obtaining the highest yield for a single plant which stood 936 gm.plant-1 and the highest value of the weight average of potato tuber which stood 169.33 gm and the lowest value for electrical conductivity of soil solution which stood 2.50 ds.m-1 compared to other interactions. While the interaction between furrow irrigation method, 8 days irrigation interval, and mechanical planting method was superior to obtain the highest value of soil porosity stood 0.48 cm3.cm-3.
