| ABSTRACT The residue of imidazolinone herbicides in soil can be detrimental to soybean cultivation in rotation with Clearfield® rice. Thus, this research aimed to evaluate the ryegrass phytoremediation capacity on the imazapyr+imazapic residue in the soil in two soil moisture conditions in the off-season, and the effect on soybean growth in the next growing season. Two experiments were conducted between 2016 and 2017 in Santa Maria, Rio Grande do Sul state, Brazil. It was used the randomized block design in a 3 × 2 factorial. The first factor being the residue in the soil of 0, 210 and 420 g c.p.·ha–1 of the formulated mixture of the herbicides imazapyr+imazapic(525 + 175 g a.i.·kg–1) applied to rice in the 2015/2016 growing season, and the second factor... |

| The main objective of this study was to characterise the cassava bagasse and to evaluate its addition in composites. Two cassava bagasse samples were characterised using physicochemical, thermal and microscopic techniques, and by obtaining their spectra in the mid-infrared region and analysing them by using x-ray diffraction. Utilising sorption isotherms, it was possible to establish the acceptable conditions of temperature and relative humidity for the storage of the cassava bagasse. The incorporation of cassava bagasse in a low-density polyethylene (LDP) matrix was positive, increasing the elasticity modulus values from 131.90 for LDP to 186.2 for 70% LDP with 30% SP bagasse. These results were encouraging because cassava bagasse could serve as a... |

| The objective of this study was to use the residues of fermented sardine to elaborate the acid fish silage and its use in feed for aquaculture. Biological assay was performed by feeding largemouth bass (Micropterus salmoides) fingerlings (initial weight 22g), with extruded diets (41% crude protein; 3,600 kcal/kg digestible energy) containing 0.0, 7.5, 10.0, 12.5, or 15.0% of fish silage in partial substitution to the fish meal. The feed conversion ratio and weight gain for the treatments were: 1.26 and 15.76g; 1.11 and 17.07g; 1.19 and 17.81g; 1.18 and 19.83g; 1.47 and 14.64g, respectively. No significant differences (P<0.05) were detected among the treatments. Results indicated that it was possible to use up to 15% of acid fish silage as partial... |

| The addition of okara flour to an emulsified meat product (Frankfurter type sausage) was evaluated based on the physical, chemical, technological, and sensory characteristics of the final product. Okara, residue from soymilk production, was provided by two soymilk producing companies whose production systems were based on the hot disintegration of the decorticated (company B) or undecorticated (company A) soybeans. The okara was dehydrated using a flash dryer and then ground into flour (>420 µm). However, The okara flours A and B showed approximately the same amount of protein (35 and 40 g.100 g-1 dwb). However, the okara flour A presented higher values (p < 0.05) for all technological functional properties studied (emulsification capacity,... |

| The objective of this research was to test the addition of soymilk residue, also known as okara, to a molded sweet biscuit (MSB). The okara was provided by two soymilk producing companies whose production systems are based on hot disintegration of decorticated (company B) or non-decorticated (company A) soybeans and separation of the soymilk. Okaras A and B were dehydrated in a flash dryer and then ground to a flour (< 200 mesh). The okara flours showed high protein (35 g.100 g-1 dwb), lipid (17 g.100 g-1 dwb), and fiber (17 to 21 g.100 g-1 dwb) contents. The water holding capacity, protein solubility, emulsifying capacity, emulsion stability and isoflavone contents found in flour A were significantly higher (p < 0.05) than in flour B. The... |

'Pêra' were sprayed in three applications, at 45-day intervals, with the following treatments: GA3 + 2,4-D at 12.5mg L-1 each; GA3 + 2,4-D at 25mg L-1; GA3 + 2,4-D at 37.5mg L-1; GA3 + NAA at 12.5mg L-1; GA3 + NAA at 25mg L-1; GA3 + NAA at 37.5mg L-1; NAA + 2,4-D at 12.5mg L-1; NAA + 2,4-D at 25mg L-1; NAA + 2,4-D at 37.5mg L-1, and a control. The treatments did not change juice quality, and showed no plant growth regulator residues 110 days after the last application in every case below 0.05mg L-1. |

| The aim of this study was to evaluate chemical attributes alterations of a clay-loam textured soil and dry mass accumulation of maize submitted to application of cassava wastewater doses in three assessment periods. The experiment was conducted under greenhouse using a completely randomized experimental design in a factorial 5 × 3, with four replicates. The analyzed factors of research were doses of cassava wastewater (0; 12.6; 25.2; 50.4; 75.6 m3 ha-1) andassessment periods (20, 40 and 52 days after germination). The following parameters were determined: electric conductivity of soil saturation extract, pH in water, content of available P, content of exchangeable K+, Ca2+, Mg2+ and Na+ of soil, dry mass of leaves and stem.

| An incubation test was conducted to investigate the effect of aging on bioavailability of chlorpyrifos in soil and to assess the feasibility of chemical extraction techniques for predicting bioavailability of chlorpyrifos in soil. Chlorpyrifos was spiked into sterilized soil and aged in microcosms for up to 120 days. The earthworms were incubated in the spiked soils, at 0, 7, 14, 30, 60, and 120 days after spiking, for a period of 7 days. After exposure, chlorpyrifos concentrations in the earthworm tissues were determined. Change in chemical extractability of soil-chlorpyrifos was measured using a several solvent systems including methanol, methanol-water (9:1), acetone-water (5:3), and water. The results show that chemical extractability and earthworm... |

| Pesticides play an important role in agriculture, prevent loses by pests which destroy cultures and causes several damages to producers and to exporting countries of agriculture products. However, pesticides leave residues where they are used. A parameter used for residue quantification is known Maximum Residue Limit (MRL). This parameter is the most important, not only in terms of public health, but mainly international trade, causing many impacts that can represent, in some cases, barriers to trade between countries, especially when established values for a country differ from those established by international organizations. The present Article show how this parameter impacts agriculture products´ trade of developing countries, based on case study. |

| Organic residue application into soil alter the emission of gases to atmosphere and CO2, CH4, N2O may contribute to increase the greenhouse effect. This experiment was carried out in a restoration area on a dystrophic Ultisol (PVAd) to quantify greenhouse gas (GHG) emissions from soil under castor bean cultivation, treated with sewage sludge (SS) or mineral fertilizer. The following treatments were tested: control without N; FertMin = mineral fertilizer; SS5 = 5 t ha-1 SS (37.5 kg ha-1 N); SS10 = 10 t ha-1 SS (75 kg ha-1 N); and SS20 = 20 t ha-1 SS (150 kg ha-1 N). The amount of sludge was based on the recommended rate of N for castor bean (75 kg ha-1), the N level of SS and the mineralization fraction of N from SS. Soil gas emission was measured for 21... |

| ABSTRACT The utilization of organic wastes in agriculture is an alternative that can reduce the amounts of mineral fertilizers applied to the soil. The aim of this study was to evaluate the accumulation of macronutrients in sunflower cv. 'Hélio 250' fertilized with cassava wastewater. The experiment was conducted in randomized block design, with six treatments (0; 8.5; 17; 34; 68 and 136 m3 ha-1 of cassava wastewater) and four replications. The accumulation of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S) were evaluated in leaves, stem, capitulum and achenes. The cassava wastewater dose of 136 m3 ha-1 promoted the greatest accumulation of all evaluated nutrients. The pattern of macronutrients accumulation occurred... |
