Vegetables productions systems are done normally with intense soil tillage causing a strong decline of soil quality. Use of conservation systems can be an alternative to recover this quality. In order to evaluate the effects of such systems on soil organic matter, an experiment has been conducted in randomized blocks design and factorial scheme 3 × 2: three soil management systems (no-tillage; reduced tillage and conventional tillage) and two cover crops (maize single; and intercropping maize with gray velvet bean―Stizolobium niveum); and repeated measures over time. |

The effect of delta-endotoxins of Bacillus sphaericus (Bs 2362), B. thuringiensis var. israelensis (Bti-H-14), and B.thuringiensis var. Kurstaki (Btk-HD-1), on oviposition and juvenile hatching of Heterodera glycines race 3 in the absence of a host plant was studied under greenhouse conditions. In experiment 1, a single dose of 1 mg of each toxin and aldicarb/g soil infested with H. glycines were compared with untreated control after intervals of 15, 30 and 60 days. The initial numbers of egs, juveniles and cysts/50g of soil were 4.4, 1.2, and 9.6 respectively. In experiment 2, two doses (0.2 and 2mg of each toxin/g of autoclaved soil) were compared with untreated control 15 days following toxins incorporation in 100g of soil inoculated with 10 cysts. The number of eggs laid at the 1 mg dose of Bs 2362 were significantly (P<0.05) higher than the control after 15 and 60 days in experiment 1 and also in experiment 2, in Bs 2362 at the 0.2 mg dose but at 2 mg dose the number of eggs were significantly (P<0.05) less than the control. In experiment 1, the number of hatched juveniles of H.glycines in treatment Bs 2362 and Btk-HD-1 were significantly (P<0.05) higher than in the untreated control after 15 days but not after 30 and 60 days. In experiment 2, only Btk-HD-1 at 0.2 mg dose had significantly (P<0.05) higher numbers of hatched juveniles than the control. The number of hatched juveniles in Bs 2362 at both doses were significantly less than the control. |
