Abstract
Vegetable oils food has become at the forefront of goods where the food gap is growing in Egypt and increase the severity from year to year so the problem of providing food oils Egyptian consumer has become one of the largest major economic challenges in the agricultural sector. Field experiments were conducted during two successive growing seasons in split-split plot design to investigate the effect of compost tea extracted from chicken manure-based thermo-philic compost (30, 50 and 70 L/fed: CT1, CT2 and CT3) under surface (SD) and sub-surface drip (SSD) irrigation system on sunflower (Helianthus annuus L.) productivity. The investigation was carried out in Research and Production Station, National Research Centre, El-Nubaria, El-Behera Governorate, on a sandy loamy soil ( 23% silt; 8% clay ). Water applied relative to the available metrological data in site as evapotranspiration (ET) in mm. The total amounted applied to the plots was 767.5 mm/ season (3223.5 m 3 /fed). Data indicated that SSD surpassed SD in all the growth characters. Increasing the applied compost tea positively affected the studied growth characters. Compost tea, beside its ability to improve the nutrient supply in the soil, also increases the efficiency of added chemical fertilization. Yield of both seeds and oil were improved under irrigation method SSD compared with SD irrigation system, with values 1314.4, 1200.9; 467.1 and 423.6 kg/fed, respectively. while increasing compost tea from CT1 to CT3 improved seed and oil yield by 11 and 31 % , respectively. Regarding to the irrigation system, SSD improved WUE than SD for both seed and oil content by about 0.41, 0.37; 0.14, 0.13 kg/m 3 irrigation water for CT3
