“…Overall, the mean was 26.02 g, which is nearly equal to the average indicated to the BRS style, which is 26 g (CARGNIM; ALBRECHT, 2010), demonstrating that decrease of M100-induced by lack of N did not happen in any of the treatments. Nascimento et al (2009) found no relationship between nitrogen fertilization and M100, a result that can be explained by the work done by Salgado et al (2012), who studied the effect of nitrogen levels in 12 cultivars and found different responses to N doses, although only three responded to nitrogen fertilization. Fernandes et al (2005), while evaluating fertilization in the planting furrow (0 and 20 kg ha -1 ) and on coverage (0 and 70 kg ha -1 ), showed a negative effect of nitrogen fertilization on the weight of 100 grains.…”

“…Soratto et al (2001) found significant differences between times of N application; the most efficient time was 15 DAE. Salgado et al (2012) found responses to N in seven out of 12 cultivars studied.…”

“…These researchers used a dose of 100 g ai ha -1 at pre-emergence (a 70% higher dose than that used in this experiment), which reduced the plant height of the cranberry bean, the lima bean, the snap bean and the white bean by more than 65% but reduced the plant height of the adzuki bean by only 25% and did not affect the plant height of the pea and the soybean. The first pod height at physiological maturity ( Figure 3A and B) is an important morphological indicator: it is recommended that plants have a minimum first pod height of 15 cm to avoid significant pod losses during mechanical harvesting (Salgado et al, 2012). In the present study, although saflufenacil treatments did not reduce the first pod height to less than 15 cm, a reduction in the pod height of 16% at 0 DAA for saflufenacil treatment compared with the control is notable because this reduction may vary based on the characteristics of the cultivar, the soil and the climate.…”

“…Apenas aos 54 DAS houve efeito significativo para as doses aplicadas para esta variável. Em estudo sobre o efeito do nitrogênio em cultivares de feijoeiro comum, Salgado et al (2012) Na Figura 5 é mostrada a análise de regressão para a variável altura das plantas no 54 DAS. Observa-se um aumento de 0,1022 cm com incremento unitário das doses de fertilizantes utilizadas, provavelmente o aumento de nitrogênio disponível no solo contribuiu com o crescimento das plantas.…”
