Effect of Brassicaceae Waste Application on Soil Nematode Community

Brassicaceae are known to contain compounds that biofumigants. This study aimed determine the effect of waste application on soil nematode community. Broccoli leaves and stems (Brassica oleracea var. italic), cabbage (B. capitate), kailan alboglabra), radish (Raphanus sativus), kamanilan weed (Rorippa indica) were tested in this study. The total glucosinolate content was estimated using palladium method with a modified spectrophotometer. experiment carried out polybags containing 500 grams soil-infested nematodes. (15 grams/polybag) chopped mixed into soil, watered, tightly closed for 14 days. arranged completely randomized design nine treatments five replications. results analysis showed broccoli, radish, fall high category (144.7-185.2 µmol/g); leaves, stems, medium (52.0-56.0 broccoli low (35.4 µmol/g). There no correlation between contents their suppressing communities at applied effluent dose. population bacterivorous nematodes increased each treatment, especially leaf treatment (R. which reached 13,008 individuals. These indicate has good potential improve health. against diversity index, an uneven evenness dominance index.
