The current study was carried out in the wooden canopy of the horticultural station in Al-Hawija district / Kirkuk governorate during the year 2020, where the seeds of Portulaca oleracea L. were planted in two dates, the first planting date is 15/9 and the second date is 1/10. The plants were treated with twenty-five fertilizer treatments that resulted from the combination of five levels of organic fertilization are (O0 = without organic fertilization, O1 = 5% poultry waste, O2 = 7.5% poultry waste, O3 = 5% sheep waste, O4 = 7.5% sheep waste), and five treatments for spraying with mineral fertilizers (S0 = without spraying, S1 = nitrogen, S2 = phosphorous, S3 = potassium, S4 = magnesium), and the seeds were planted in 5 kg pots, and the experiment was designed with a factorial experiment inside split-plot system according to the Randomized Complete Block Design. Traits have been studied was the levels of fatty acids (a-linolenic acid, Ecospentaenoic and Docosahexaenonic), and some active compounds (berberine, vitamin C, and carotenoids). The results are as follows: The early date 9/15 was significantly superior to the late date 1/10 in all studied traits. The organic fertilization O3 and foliar S2 treatments were superior in the levels of a-linolenic acid, Ecospentaenoic, Docosahexaenonic and berberine, while the O4 and S4 treatments were superior in the concentration of vitamin C and carotenoids. The interactions of these superior transactions also interactions each other and with the first date in achieving the best values for the studied traits. [ABSTRACT FROM AUTHOR] |
