Infestation of weed species in pre-planting of soybean in succession to winter crops

Abstract: -This study aimed to evaluate different crops and plant species planted after soybeans for one year, in terms of their potential to inhibit the occurrence of weed species. The following crops that were planted as second crop after soybeans were evaluated: (1) corn (Zea mays) planted at spacing of 90 cm between rows, intercropped with Brachiaria ruziziensis in the inter-rows; (2) sunflower (Helianthus annuus); (3) crambe (Crambe abyssinica); (4) radish (Raphanus sativus); (5) rapeseed (Brassica napus); and (6) … Show more

“…Shannon's diversity index (H') and Pielou's evenness were calculated to be 2.30 nats ind -1 and 0.69, respectively. The values for H were similar to those reported in the literature by Concenço et al (2013) and Mata et al (2016) for corn and rice crops, respectively, and are considered average for Shannon's diversity index, which ranges from zero to five (Kent and Coker, 1992).…”

“…Commelina benghalensis is remarkably resistant to glyphosate use in chemical management, possibly due to the unregulated use of herbicides, which leads to the selection of more tolerant plants over time. Its resistance may also be due to the low efficiency of the mechanical methods used for its control, and to its rapid reproduction, which may be vegetative or by seeds (Concenço et al, 2013;Santos et al, 2001). There have been reports in the literature of the species in the states of Bahia (Silva et al, 2006), Rio Grande do Norte (Moura , Minas Gerais (Sarmento et al, 2015), Goiás (Santos et al, 2017), Rio de Janeiro (Oliveira and Freitas, 2008), and Paraná (Costa et al, 2014), among others.…”

“…Heinz et al (2011) of phosphorus, 94.4 kg ha -1 of potassium, 14.7 kg ha -1 of calcium, 6.5 kg ha -1 of magnesium, and 12.6 kg ha -1 of sulfur back to the soil after harvest. Recent studies also indicate that the dry biomass of crambe helps to reduce soil infestation with weeds (CONCENÇO et al, 2012(CONCENÇO et al, , 2013PACHECO et al, 2013).…”

“…It is presented as an alternative to keep the soil covered, making difficult the emergence of weeds in the off-season and consequently in the subsequent cultivation. That efficiency is due to its high production of biomass and excellent ground cover (CONCENÇO et al, 2013).…”
