EFFECT OF ADDING COMPOST TEA , SPRAYING SEAWEED EXTRACT AND STORAGE PERIOD ON THE STORAGE ABILITY OF CHINESE CABBAGE BRASSICA RAPA SUBSP. CHINENSIS

The experiment was conducted during the winter agricultural season 2021_2022 in a field belonging to the Agricultural Research Station of the College of Agriculture - University of Basra, with the aim of studying the effect of adding compost tea at levels of cow compost tea 5 kg. 20 l‾¹ , poultry compost tea 5 kg. 20 l‾¹ in addition to control distill water only, spraying seaweed extract(agazone) at levels of (0, 1.5, 3) mL. L‾¹ and the interaction between them in the storage ability of Chinese cabbage hybrid Mei Qing Choi. After harvesting Chinese cabbage packed in perforated polyethylene bags and stored in the refrigerator at a temperature of 4 ° C. during the period (5, 10, 15) days. The experiment was carried out as a factorial experiment according to the split-split plot design in a randomized complete plot design (R.C.B.D.). with three replicates, so that the experiment includes 54 experimental units. The results were analyzed by the analysis of variance and mean values were compared using the Revised Least Important Difference Test at 0.05 probability. Results showed the treatment of adding poultry compost tea 5 kg. 20 L‾¹ outperformed compared to the treatment of cow compost tea 5 kg. 20 L‾¹ and control treatment in reducing the percentage of decay , the percentage of weight loss , as the plants sprayed with seaweed extract with a concentration of 3 mL.L ̄¹ significantly excelled as compared with the rest concentrations 0 and 1.5 mL. L‾¹ in reducing the percentage of weight loss, percentage of decay, total chlorophyll , carotene, vitamin C concentration and total soluble carbohydrates.
