Role of Organic Fertilizer on Quality and Nutrient Content of Three Green Onion Cultivars

This paper has been conducted at the researches station, college of agriculture, Kirkuk University, during the winter growing season 2019/2020 to investigate the effect of organic fertilizers ''Magic Leon'' at two levels 0, 300 kg/ha, as soil application which is added to the soil two weeks before planting. Also, spraying three times of Bio20 at a concentration of 2 ml/l, in 15-day intervals after one month of planting until a drip of 2-3 drops/litter of tween-80 was added to the solution as a surfactant agent, on quality and nutrients content of three local cultivars, Which were planted in 1/November/2019 by using onion sets of cultivars namely, Red and White (Iraqi cultivars) and White Syrian cultivar. The data that were recorded have been the percentage of nitrogen, phosphorous, potassium, sulphurs, carbohydrate, and protein in the bulbs; also, the percentage of bulbs doubling—factorial experiment 2x2x3 in RCBD design with three replicates. The results show that 'Magic Leon' gave a significant increase in carbohydrate percentage 5.83%, while Iraqi cv. significantly affected bulb doubling 28.33%. The white Syrian cv gave a significant value in carbohydrate content which reached 5.93%.
