| Abstract | ||
| The experiment was carried out on winter season of 2013/2014 at the horticultural gardening landscape research station/college of agriculture/University of Tikrit to study the effect of variety and fertilizers addition method on growth and yield of cabbage. The experiment included three varieties of cabbage; Sakata, Blue Jays, Copenhagen-market, with four fertilization treatments; local poultry manure, humus, mushroom wastes, and chemical fertilizers. The experiment was carried out using the split-plot design based on R.C.B.D. The results of the experiment statistically analyzed and compared with Duncan's multiples . The results of the experiment showed that poultry manure was significantly on total chlorophyll and sugar percentage, and gave the lowest value of nitrate. Addition of humus T2 was significantly on the leave area. Mushroom wastes treatment was more effective in the oil percentage. The chemical fertilizer was more effective on total chlorophyll, length and diameter of cabbage head but it gave high nitrate level. From the results it was appeared that there were significant differences in the verities treatment; as Copenhagen-market showed highest result of head length. Blue Jays variety gave highest total chlorophyll, biological yield, and nitrate. Sakata appeared with higher leaf area and low content of nitrate.The experiment results showed significant differences with the combination between fertilization and varieties. As the poultry manure with Blue Jays gave high outer leaves number and chlorophyll. While humus combination with Blue jays gave high leaf area. The combination of mushroom wastes and Sakata variety gave high head length, diameter, and nitrate concentration. The combination of mushroom wastes with Copenhagen-market gave high total yield, while the chemical fertilizers combined with Sakata gave high oil percentage. | ||
