One of the important fiber and green manure crops is Crotalaria juncea L. (2004). The tests were separated by post hoc Tukey's honest significant difference (HSD) test. Rev. Ali, H., Khan, E., and Sajad, M. A. Brasil. 25, 184–187. Midseason mowing provides the opportunity for regrowth before the crop winter-kills and reduces the production of fibrous plant material. Performance of Crotalaria juncea after green manure species cultivation in soil with tebuthiuron and vinasse. Efforts to produce engineered groundnut plants with viral genes yielded encouraging results. H2SO4) scarification, respectively, for 60% germination (Mishra and Sen, 1984). Light brown (Type I), dark brown-black (Type II) and dark brown-black white-mottled (Type III) seeds that were separated from a mass collection of Rhynchosia capitata required 60, 80 and 90 min of acid (conc. No use, distribution or reproduction is permitted which does not comply with these terms. Oxford 64, 703–710. Phytoremediation of soils contaminated with picloram by Urochloa brizantha. 0 kg N/ha). These species, in association with vinasse as source of soluble carbon, can decontaminate the system more effectively than C. cajan and C. ensiformis, thus enabling the bioindicator C. juncea to grow and develop healthier in the presence of residual tebuthiuron. Chemosphere 91, 869–881. Primary source of inoculum is likely to be provided by numerous weeds. Smallholder farmers use mulch from slashing of various weeds and Mucuna vines to spread in their crops such as in a maize field. doi: 10.7213/estud.biol.7338. J. Agricul. Reproduced from Muliokela, S.W. The GI was used to assess the toxicity of soil samples in the test organism, according to Equation 1 (Labouriau and Agudo, 1987): Procedures of Shapiro–Wilk and Bartlett checked the normalcy and homoscedasticity of the dataset, respectively, and the analysis of variance tested the significance of effect of factors on the soil phytoremediation. We argue that it is imperative to evaluate the ecotoxicological potential in a broader time-dependent approach to demonstrate the success of bioremediation strategies (Banks and Schultz, 2005). Núcleos 5, 1–10. Franco et al. Other fibers, such as jute, contain substantial fractions of noncellulosic material, lignins and hemicelluloses, which lower strength and break extension. It was further improved when tissue-specific, promoter-driven Cry genes were introduced in rice (Datta et al., 1998) and the insect-resistant ability of rice was successfully demonstrated in fields (Tu et al., 2000). A. D., Ferreira, L. R., et al. Pesq. Infestation patterns of weed communities in raw cane agroecosystem (Padrões de infestação de comunidades de plantas daninhas no agroecossistema de cana-crua). Received: 02 October 2020; Accepted: 10 November 2020; Published: 05 January 2021. Other reliable and executable bioindicators of soil decontamination are finger millet (Eleusine cocracana), for chlorimuron-ethyl and sulfumeturon-methyl (Assis et al., 2010), and cucumber for picloram (Galon et al., 2017). In another experiment, seeds of I. corei were given cycles of 1-hr of soaking in conc. Compost is mostly suitable for vegetable production since it uses more labor to produce than other manures. Temperature Effects. Maintenance of sufficient plant density is important to discourage landing of thrips. Among the herbicides commercialized for sugarcane, tebuthiuron is the most used, whose selective pre-emergent action controls main weeds in the crop (Moraes et al., 2016). The vinasse was added first, at 150 m3 ha−1 (150 ml dm−3), following the CETESB Technical Standard P4.231/2005 (2005) on the procedures to apply vinasse to agricultural soils. Straight fertilizers are those that supply or contain only one major plant nutrient such as N or P or K. For example, ammonium nitrate and urea are straight fertilizers because they contain only N. Similarly, Solubor contains only boron. Thus, seeds of this species have the potential to form a persistent seed bank. Gerald E. Brust, in Safety and Practice for Organic Food, 2019. Crotalaria viminea Wall. There are other cover crops like Red Clover (Trifolium pratense) that fix lots of nitrogen but are much less expensive and better adapted to northern temperate climates. Brasil. Comparison of plants for germination toxicity tests in petroleum-contaminated soils. Green manure species selected for the trial in greenhouse were jack bean [Canavalia ensiformis (L.) DC. Trop. In some studies of seed variation, seeds are collected from a large number of plants at a population site and pooled. Effect of population density of Canavalia ensiformis on phytoremediation of soil contaminated with sulfentrazone (Efeito da densidade populacional de Canavalia ensiformis na fitorremediação de solo contaminado com sulfentrazone). Rodrigues, B. N., and Almeida, F. S. (2011). These references supported the major findings in this study on the negative effect of tebuthiuron on biomass accumulation in roots and shoots of green manures species. Degradation and adsorption of diuron in soils treated with vinasse (Degradação e adsorção de diuron em solos tratados com vinhaça). It is considered a residue from the alcohol production, generated at a 10–14:1 ratio (Assad, 2017). 69, 13–16. Labouriau, L. G., and Agudo, M. (1987). Pest Manag. Ambayeba Muimba-Kankolongo, in Food Crop Production by Smallholder Farmers in Southern Africa, 2018. Screening out of species of green manure as potential phytoremediators for tebuthiuron in soil, with and with no vinasse, accordingly is the scientific point of this study. The vinasse was collected from a sugar-energy plant in the Dracena-SP region using sterile glass bottles. The nature and physicochemical properties of the pesticide (e.g., chemical stability, spatial structure, feedback effect, and intermediate metabolites) and its multiplicity of interactions with the rhizosphere are factors influencing greatly its bioavailability and, of course, kinetics of biodegradation. The reason behind the high phosphorus uptake is buckwheat’s ability to acidify the rhizosphere by oozing out protons (H+), which in turn solubilize the calcium-bound phosphorus in an alkaline soil, thus makes phosphorus available to the plant (Zhu et al., 2002) (Fig. This gave results with considerable success, confirmed by the 15-year HD/R resistance management strategy for Bt crops in North America (Huang et al., 2011). Studies conducted on monkeys (Mao et al., 2016) and mice (Xu et al., 2009) for food and feed assessment confirmed the safety of the Cry1Ab/Ac protein (Koch et al., 2015). Compound fertilizers supply more than one major element. TO: Karl Trepka FROM: Eric Koperek = erickoperek@gmail.com SUBJECT: Sunn Hemp (Crotalaria juncea) DATE: PM 4:02 Thursday 15 September 2016 TEXT: (1) Seed for Sunn Hemp (Crotalaria juncea) is costly in the United States. Our purpose was to study the residual effect of doses of the Crotalaria juncea green manure applied in broccoli crop in the zucchini-maize succession. (Guia de herbicidas). The highest estimations for both the maximum of size and absolute growth rate for this potential phytoremediator in soil with no tebuthiuron supported the high phytotoxicity of this herbicide to the primary growth. Practically, this molecule more severely disabled both C. cajan and C. ensiformis to grow and develop as healthily as possible prior to sowing C. juncea for monitoring the potential phytoremediation of soil with green manure. Caat. When some caterpillars and moths ingest Bt toxin with their food, Cry proteins bind to receptors in their gut epithelium. (2012a). 394 p. Inorganic fertilizers are divided into two different types, namely straight fertilizers and compound fertilizers. The monitored parameters were (i) stem diameter in millimeter, (ii) height of shoot in centimeter, and (iii) number of leaves. BM, JC, and PL: visualization. The disease may have been existing for a long time and attributed to PBNV because of striking similarity in symptoms that include terminal bud necrosis (Prasada Rao et al., 2003). Treatments containing vinasse had to undergo manual compound application to endure homogeneity. Utilizing a cereal–legume rotation can be beneficial to such farmers. It is found that buckwheat possesses the capacity to take up about 10 times more phosphorus than wheat, thus it is regarded as an efficient phosphorus scavenger (Zhu et al., 2002). Still, its environmental effects combined with herbicides are yet to be determined. Topcrop. However, vinasse can also be used to enrich soils due to its nutritional value. The observations occurred between May and July 2019. They used sunn hemp (Crotalarea juncea) as the bioindicator plant.
