Understanding the important of good and healthy quality of vegetables is necessary to be brought into farmers, consumers and government official. Data on the quality of vegetables based on the pesticide residues in Bengkulu province is rare, including Cabbage. Research with title: Quality improvement of Cabbage through sustainable growing crop management was conducted in Rejang Lebong, Bengkulu. The objectives was to measure the insecticide residues in cabbage that were subjected to three different growing techniques management, i.e. Organic, Integrated Pest Management, and Conventional, and grown at two different time of planting. The outcomes of the research were the method of growing cabbage that produce high quality of crop with low pesticide residue, but commercially still profitable. Research was conducted in Kecamatan Selupu Rejang, Kabupaten Rejang lebong. Two factors were applied and arranged in Factorials Randomized Completely Block Design. The first factor was time of planting, i.e. Wet (MT1) and dry (MT2) season; and second factor was the application of three different growing techniques management, i.e. Organic (P1), Integrated Pest Management (P2), and Conventional (P3), with 3 replications and this produces 18 experimental units. Eight variables were measured includes height of plant, crop diameter, sample weight, weight of cabbage per unit area, insecticide (organophosphate) residues in crop sample, insecticide (organophosphate) residues in soil sample, number of Diamond back moth (P. Xylostella) and Cabbage heart caterpillar (C. Binotalis) in sample crops and soil, and number of nematodes in the soil. The results show that the second season (dry season), regardless the growing techniques management, significantly improved the height of plant, the diameter of crop and consequently improved the weight of crop/area. It was also found that the average weight of sample of organically grown cabbage was lowest compared to the other growing technique management i.e. IPM and conventional. Interaction were found between growing technique management and time of planting, in which during the first growing season the plants cultivated in Integrated Pest Management and Conventional techniques had higher number of leaves, but it did not improve the diameter of crop. Surprisingly, the growing techniques management did not affect the insecticide residues in the sample crops and in the soils. In addition, the nematodes in the soil that survive during the two growing seasons have decreased in number.
