| Abstract | ||
| Two field trials were performed at Sakha Agricultural Research Station Farm, Kafr El- Sheikh Governorate, during the two winter seasons 2017/18 and 2018/19 to study the influence of irrigation scheduling; traditional watering (I1), irrigation at 1.2(I2), 1.0(I3) and 0.8(I4) of accumulative pan evaporation(APE) and four systems of sole and intercropping pattern; sole green onion cv. Giza 6(P1), sole lettuce cv. Balady(P2), 2green onion : 1 lettuce(P3) and 1 green onion : 2 lettuce(P4) in a split plot design with four replications. Data indicated that the highest values for seasonal applied water (AW) and water consumptive use (CU) were registered under irrigation treatment(I2). For water consumptive use efficiency (Ecu%), the highest values were recorded under treatment (I1). productivity of irrigation water (PIW) and water productivity (WP) were clearly impacted by irrigation treatments, intercropping patterns in addition crop type where the highest values also recorded I2 besides P4. The results also revealed that yield, yield component and quality parameters for green onion; plant height, fresh weight of leaves, plant weight, leaf area/ plant, chlorophyll content and total yield as well as lettuce; plant height, leaf area/ plant, chlorophyll content, plant weight, head weight, diameter and total yield increased with increasing irrigation applied water. On contrary, for crop pattern the highest values for yield component recorded under sole crop but the total yield recorded under 1:2green onion- lettuce planting pattern. For gross return and increasing income was attained I2 besides P4. Land equivalent ratio (LER) exhibited higher values with I1 besides P4. | ||
