This study checked the nitrogen (N) uptake, fate of the N fertilizer, fertilizer recovery efficiency (FRE) and the residual amount of N fertilizer in the soil via 15N-labelled fertilizer applied to soybean (Glycine max L. Merr.), to explain any differences in the yields. Two soybean field experiments were established in Brazil, one conducted in a tropical (Trop) zone located at Cerrado Biome and the other in a subtropical (Subt) environment. The experimental design was a 2-factor in randomized complete block with four replications. Five doses of N (0, 20, 40, 80 and 120 kg ha−1) were applied at two soybean growth stages (VE and R3). For all treatments, except No-N, 15N-labelled fertilizer was used. The N uptake and the amount of N fertilizer were analysed in the roots, shoots, grains and whole plant, the FRE and yield by soybean, and the residual of fertilizer in the soil. The total N uptake (Nplant) was greater with fertilization at R3 stage compared to the other stage, and N application increased the yield just at this stage and in the Trop condition. The increase in N shoot (not specifically from fertilizer) with the application at R3 appeared to be related to the increased in yield. However, the N from fertilizer found in the plant shoot was about 20% higher when fertilizer was applied at VE compared with R3. Under Subt condition, the FRE averaging 55%. In contrast, the FRE decreased from low to high nitrogen rates (64 to 40%, respectively) when soybean grown under Trop condition. Most N from fertilizer (38%) was found in the grains, followed by the shoot (14.6%) and the root (0.58%). The use of N fertilizer at reproductive growth stages is a better approach to meet soybean N demand through N fertilization. Potential yield gains are more reliable under Trop condition.

Summary Salpingogaster nigra is a promising species for biological control of the spittlebug Mahanarva spectabilis Distant (Hemiptera: Cercopidae). This study determined the biology of the immature stage, as well as aspects of S. nigra adult behavior. Female fertility, egg viability, and the duration and viability of the larval and pupal stages were evaluated. Behavioral aspects were studied by the olfactory response of mated females, with a Y-type olfactometer. We assessed predator response to spittlebug nymphs vs. clean air; spittlebug nymphs vs. spittlebug foam, and spittlebug foam vs. clean air. Female fecundity reached 25.1 ± 6.1 (SE) eggs per female per d, and egg viability was 64.0% ± 4.5%. Duration and viability of the larval period were 10.5 ± 0.4 d and 10.0 ± 2.1%, respectively. Duration of the pupal stage was 10.7 ± 0.2 d, and viability was 88.1% ± 5.1%. Significant preference was observed for odors from nymphs in contrast to clean air. Results show that although S. nigra adults, eggs, and pupae may be kept in the laboratory, the mass breeding of the predator presently is not feasible due to low larval viability. |
