Reports state that the Cry1Ab/Ac gene has no significant effects on nontarget organisms such as the silkworm (Yao et al., 2006), the planthopper, the leafhopper (Chen et al., 2006), or common predatory arthropods (Xu et al., 2011). However, the difficulty in producing seed caused many farmers toabandon the growing of this crop. Therefore, C. juncea was highly susceptible to tebuthiuron. Also, round and flat seeds of four seed lots from two hybrids were stored at three moisture levels (120, 140 and 160 g kg−1) at 30, 40 and 50°C in foil packets. Production of biomass by green manure species in soil with tebuthiuron and vinasse. (Franco et al., 2015). Madalão, J. C., Pires, F. R., Cargnelutti Filho, A., Chagas, K., Nascimento, A. F., and Garcia, G. O. The spectrum of jute-infesting pests has increased. Brazilian system of soil classification (Sistema Brasileiro de Classificação de Solos). Ali, H., Khan, E., and Sajad, M. A. 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. Large (3.3 mm in length), medium (2.8 mm) and small (2.4 mm) seeds from a mass collection of Eurotia lanata tested at 7.2, 10.6, 13.3 and 24.4/15.6°C exhibited an increase in germination at each temperature regime with an increase in seed size (Springfield, 1973). It is obtained in two ways: by growing green manure crops or by collecting green leaf (along with twigs) from plants grown in wastelands, field bunds and forest. The average local temperature and precipitation are 22.1°C and 1,200 mm, respectively. The application of Bt is more fruitful when sprayed early, that is, when early instar larvae are present, because older larvae are more tolerant. Núcleos 5, 1–10. Forage legumes fix more N2 (from 91 to 240 kg ha−1, but more typically from 196 to 240 kg ha−1) than grain legumes (from 37 to 167 kg ha−1). TSV can be detected by ELISA, nucleic acid hybridization, and RT-PCR (Prasada Rao et al., 2003). Rev. Handbook of Energy Crops. Other fibers, such as jute, contain substantial fractions of noncellulosic material, lignins and hemicelluloses, which lower strength and break extension. Mulches are plant materials such as straw of the previous crops that are used as a soil cover mainly for conservation of soil moisture. LF, EP, RT, EB, and PL: conceptualization. Farmers prefer the use of chemical pesticides for pest control in jute fields. doi: 10.3738/nucleus.v5i2.85. Weed Sci. 39, 245–250. ABNT, Associação Brasileira de Normas Técnicas. A. D., Ferreira, L. R., et al. The organic matter, total N, available P and S of the soil was only slightly increased by the incorporation of green manures. Red dots indicate protons (H+) oozing out from buckwheat roots and green dots indicate forms of phosphorus (H2PO4−) available to plants in calcium-bound state, that is, calcium-bound phosphorus (CBP). Rev. Madalão, J. C., Pires, F. R., Nascimento, A. F., Chagas, K., Cargnelutti Filho, A., and Oliveira Procópio, S. (2016). To an optimization of visualization of non-Boolean patterns in chromatic wireframe by contour plotting approach, fuzzy logic to turn any ambiguity off from the data was implemented. Figure 3. doi: 10.1021/jf0106751. (2013). The average temperature and relative humidity were 22.6°C and 62.9%, respectively, also obtained from the Dracena EMA/FCAT weather station. doi: 10.5935/1806-6690.20170004, Ferraço, M., Belo, A. F., Madalão, J. C., Pires, F. R., and Celim Filho. Creamer and Baldwin (1999) observed that buckwheat possesses a carbon:nitrogen ratio of 34 (C:N = 34), thus immobilizing nitrogen during decomposition. Kinetic parameters for the growth and development of green manure species in soil with tebuthiuron and vinasse. Rev. (2004). Several species of Crotalaria are cultivated as crops to be consumed by human populations throughout the world. Biossistemas 12, 52–67. This causes the membrane pores of the gut epithelium to open, causing an influx of water followed by cell swelling and lysis (Bravo et al., 2004). Plant heigh, leaf production, and area all increased in C. juncea with decreasing concentration of contaminant. Phytoremediators response occurred regardless of their morphological traits. Pesq. 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). Many farmers who have used buckwheat as a cover crop refer to its ability to “mellow” the soil, leaving it in a friable and fertile state, ready for planting (Petrich, 2000). Source: James A. Duke. The adaptability of insects to some Bt toxins is a persistent concern for the success of first-generation Bt crops. São Paulo: Monography, University of São Paulo, 131. It is widely grown in many areas of the tropics and subtropics, including Africa, Asia and Australasia, as a green manure crop and for its fibre [ 200 The New RHS Dictionary of Gardening. Cienc. According to the Köppen (1948) classification, the regional climate type is Aw (tropical humid). Brasil. Kapok, which is a hollow fiber used for buoyancy, is a seed fiber, and the coarse fiber coir, from the outer coat of the coconut, is a fruit fiber, but both have limited textile usage. Microbial activity of soil with sulfentrazone associated with phytoremediator species and inoculation with a bacterial consortium. Agrop. The amount of each nutrient varies considerably depending on: the method by which the manure is prepared (i.e., exposure to rain during storage may leach nutrients out of the manure); the amount and type of bedding materials used (i.e., use of leguminous crops is best); and the type and age of livestock from which droppings are obtained (i.e., old livestock produce more N). (2017). (2013). Tebuthiuron is highly available and can move smoothly through the structure of agricultural soils with lows levels of organic matter and clay (Chang and Stritzke, 1977). This study was carried out in a crop succession system organized in three crops, with seven treatments and four major doses of green manure as 0, … (2016) reported similar trend for the dry mass of P. glaucum after phytoremediation by C. juncea and C. ensiformis. Estimates for the absolute primary growth rate for the C. cajan in soil with tebuthiuron and vinasse combined was the lowest (Table 2). Biochemical and genotoxic effects of a commercial formulation of the herbicide tebuthiuron in Oreochromis niloticus of different sizes. About 2% of these biopesticides available on the market are based on the entomopathogenic Gram-positive soil bacterium Bacillus thuringiensis Berliner (Bt) (Bravo et al., 2011). Characteristics of green manures include a crop that is fast growing with rapid decomposition and quick nutrient release. Victoria Filho, R., and Christoffoleti, P. J. doi: 10.1007/s11270-005-8553-4, Belo, A. F., Pires, F. R., Bonomo, R., Cargnelutti Filho, A., and Tenis, L. H. O. Questions and Answers for Using Sunn Hemp (Crotalaria juncea L.) as a Green Manure Cover Crop 3 in other areas. In: Sugarcane and its impacts: an academic view (Cana-de-açúcar e seus impactos: uma visão acadêmica). ), Fabaceae (Leguminosae; Crotalaria spp. Sunn hemp suppresses weeds, slows soil erosion, and reduces root-knot nematode populations. This problem was cleverly solved in the mid-1980s when scientists first introduced Bt Cry genes into the genomes of tobacco and tomato plants and the proteins were expressed directly in plant tissues (Fischhoff et al., 1987; Vaeck et al., 1987; Perlak et al., 1991). 51, 1992–1999. Characteristic symptoms are necrosis on stems and petioles and necrotic spots on pod shells. In cordage, abaca and sisal were dominant, but have been replaced by synthetic fibers. The fate of this herbicide and its potential metabolites in soil and into tissues of green manure species, especially M. pruriens and P. glaucum, is prone to scaled up designs toward an effective and safe industrial usage and could be the focus of further investigations. The determination/quantification of height, stem diameter, and number of leaves in all plants were monitored, as well as other morphological traits for drafting any inference on biomass production.
