Um dos pilares do sistema de plantio direto (SPD) é a rotação de culturas, feita de forma planejada para atender o objetivo que se deseja, que dentre outros, pode auxiliar no controle de fitonematoides existentes no solo. O objetivo desse estudo foi quantificar de biomassa de plantas de coberturas e o controle efetuado sobre a população de fitonematoides presentes na área. O estudo foi conduzido em Uberaba, MG, em Latossolo Vermelho Distrófico, textura franco argilo-arenosa. O delineamento utilizado foi inteiramente casualizado, foram avaliados quatro tratamentos para o controle populacional dos fitonematoides: 1-Crotalária juncea; 2-Milheto; 3-Tratamento químico (Soja NA5909RG com o nematicida Fluensulfona); 4-Pousio (vegetação espontânea = testemunha), com cinco repetições. A amostragem para avaliação da massa fresca (MF) e seca (MS) das coberturas foi realizada em áreas de 2m2. Para análise nematológica, foram feitas amostragens antes do plantio, aos 45 e 90 dias após o plantio (DAP), sendo coletadas 5 amostras de solo em cada parcela, na profundidade de 0,30 m. A produção de MF e MS de crotalária e milheto foram 10,3 e 46,5% superiores ao pousio, respectivamente. Nas áreas de soja tratada (tratamento químico), 90 DAP foi encontrada a maior população de fitonematoides, seguido pelo pousio, milheto e crotalária. Crotalária e o milheto no SPD proporcionam um controle populacional de Meloidogyne incognita, equivalente a 95 e 93%, respectivamente, enquanto que o tratamento químico e a testemunha reduziram a infestação populacional em 8%.

The recent availability of soybean cultivars with resistance to dicamba herbicide has increased the risk of injury in susceptible cultivars, mainly as a result of particle drift. To predict and identify the damage caused by this herbicide requires great accuracy. The objective of this work was to evaluate the injury caused by the simulated drift of dicamba on soybean (nonresistant to dicamba) plants assessed visually and using the Triangular Greenness Index (TGI) from images obtained from Remotely Piloted Aircraft (RPA). The study was conducted in a randomized complete block design with four replications during the 2019/2020 growing season, and the treatments consisted of the application of six doses of dicamba (0, 0.28, 0.56, 5.6, 28, and 112 g acid equivalent dicamba ha−1) on soybean plants at the third node growth stage. For the evaluation of treatments using the TGI technique, spectral data acquired through a Red Green Blue (RGB) sensor attached to an RPA was used. The variables studied were the visual estimation of injury, TGI response at 7 and 21 days after application, plant height, and crop yield. The exposure to the herbicide caused a reduction in plant height and crop yield. Vegetation indices, such as TGI, have the potential to be used in the evaluation of injury caused by dicamba, and may be used to cover large areas in a less subjective way than visual assessments.

Growth regulators such as biostimulants can promote positive changes in the plant physiological processes, being alternatives to help the seedlings development with high seedlings quality. Therefore, this study aims to evaluate the characteristics of industrial tomato and pepper seedlings fertilized with biostimulants. The experimental design was a randomized block design with six treatments and four replicates. The treatments were: fertilizers with different nutrient compositions, being, T1: formulated mix containing N, P and K, using as sources urea, monoammonium phosphate, and potassium chloride respectively; T2: biostimulant 1 with auxin; T3: biostimulant 2 with fulvic acids and inositol; T4: biostimulant 3 with organic carbon; T5: zinc sulfate, and T6: distilled water (control). Root length and root dry mass were not affected by the treatments applied in pepper and tomato seedlings. Stem diameter, length, and dry mass, and the number of leaves were superior in pepper when NPK or zinc sulfate was applied. The same variables were superior in industrial tomato when NPK or biostimulant 3 (organic carbon) was applied. The results found indicated that amendments can be used to produce more vigorous pepper and industrial tomato seedlings.

Filter cakes are solid organic byproducts of the sugarcane industry that are generally used as fertilizers for crops such as coffee. Filter cake application has improved soil chemical, physical and microbiological attributes, especially for weathered soils. This study aimed to evaluate the influence of filter cake applications on the soil attributes cultivated with coffee in a Cerrado region. The study was conducted in a commercial coffee crop area (coffee cultivar Topázio MG 1190) in a Dystrophic Oxisol. The experimental design used was randomized blocks, in a factorial scheme of 4 x 4, with four doses of filter cake applied in the planting furrow (0, 4, 8, 12 L m-1) and four soil depths (0-0.1, 0.1-0.2, 0.2-0.3, 0.3-0.4 m). Soil density, soil mechanical resistance to root penetration, moisture, porosity (micro, macro, and total) and aggregate stability were evaluated. In general, the application of sugarcane filter cake over a long period has little effect on the soil's physical attributes, regardless of the filter cake rate used in the coffee crop. Only the soil porosity is affected by 12 L m-1 of filter cake, increasing the micro and macroporosity of the soil and promoting adequate conditions for the growth of coffee root, which can generate large soil water retention, benefiting coffee crops in the long-term.

The decomposition and release of nutrients from plant residues that precede the cultivation of vegetables can positively affect the morphological parameters and crop productivity. The objective of this study was to evaluate the effects of plant residue decomposition and the cycling of macro and micronutrients of four cover crops preceding the broccoli production (single head Avenger hybrid). A 4x3 factorial scheme was implemented including four cover crops: signal grass (SG), pearl millet (PM), sunn hemp (SH), mixture PM+SH; and three doses of mineral fertilizer: 0, 50 (200 kg ha-1 of P2O5, 50 kg ha-1 of K2O, 75 kg ha-1 of N) and 100% of the recommended fertilizer dose (400 kg ha-1 of P2O5, 100 kg ha-1 of K2O and 150 kg ha-1 of N). Fresh (FB) and dry biomass (DB), residue decomposition, nutrient cycling of cover crops, the number of leaves, head height (HH), stem diameter (SD), head diameter (HD), head fresh-biomass (FB), head dry biomass (DB) and broccoli yield were evaluated. The FB production from PM (25.9 t ha-1), SG (23.3 t ha-1) and mixture PM+SH (23.9 t ha-1) were similar, while the largest production of DB occurred in the SG (11.9 t ha-1). The lowest rate of decomposition and the greatest half-life time of residues occurred where PM was present. The accumulation and nutrient cycling follow the sequence K>N>Ca>Mg>P>S and Mn>Zn>B>Cu for all cover crop treatments evaluated. The highest SD (51.95; 51.44 and 50.67 mm), HD (187.97; 187.41 and 183.48 mm), FB (1.01; 1.00 and 0.97 kg), DB (0.08; 0.07 and 0.07 kg) and broccoli yield (25.3; 24.9 and 24.7 t ha-1) was observed in the 100% dose of mineral fertilizer and on the residues of SH or PM+SH mixture, respectively.

Vermiculite is an expansive material that can be used for crop production. However, information about the use of vermiculite in vegetable production is scarce. Thus, this study's objective was to evaluate the effects of vermiculite levels incorporated into the soil (Red Latosol Dystrophic) for beet (Beta vulgaris L.) crop production. The experiment was performed during spring using the beet cultivar 'Early Wonder Tall Top' and 0, 2, 4, 6, 8, and 10 t∙ha-1 of vermiculite incorporated into the soil before seedling planting. The increase of the vermiculite doses caused a linear decrease of the fresh root and leaf weight. The yield reductions were due to the great water holding capacity of the vermiculite and the consequent high incidence of cercosporiosis (Cercospora beticola Saac).

Zucchini (Cucurbita pepo L.) is a horticultural plant species of great socioeconomic value in tropical countries such as Colombia and Brazil. The production of zucchini is qualitatively and quantitatively affected by many diseases, especially viruses belonging to the Potyvirus (Zucchini yellow mosaic virus - ZYMV) and Comovirus (Squash mosaic virus - SqMV) groups. The primary strategy to reduce the spread of potentially damaging plant viruses is the development of genotypes with genetic tolerance; however, there are not many zucchini genotypes with multiple tolerance. Therefore, this study evaluated 66 zucchini genotypes to find sources of tolerance to the ZYMV and SqMV viruses. This experiment was conducted in a completely randomized design using genotypes from the germplasm bank of the Federal University of Uberlândia, including the genotypes: Emanuela (common commercial genotype) ‘Tronco Caserta’ (susceptible genotype) and PX 13067051 (resistant genotype). Leaf extracts containing viral particles were used as inoculant, and the distribution of grades of tolerance was recorded at the seedling stage. The lineages UFU-C×UFU-A#18#3;1, UFU-C×UFU-F#19#11;3, UFU-F#4#9;1, and UFU-D×UFU-F#7#21;1 and the Emanuela cultivar are alternatives for the production of new zucchini genotypes or hybrids with tolerance to the viruses ZYMV and SqMV. More severe symptoms were observed, as well as a larger number of susceptible genotypes for the ZYMV virus, indicating that this virus has great potential for causing damage and losses to zucchini crops.

O uso de fertirrigação com efluente líquido de biodigestor é uma alternativa interessante para redução dos custos de produção na cultura do café. O objetivo deste estudo foi avaliar o uso de diferentes doses de água residuária provenientes de um biodigestor, no desenvolvimento inicial do cafeeiro. O experimento foi conduzido em casa de vegetação modelo em arco, em vasos de 13 dm3. O delineamento utilizado foi de blocos ao acaso com seis doses de fertirrigação com efluente líquido de biodigestor. Os tratamentos constituíram em T1 = Água + Adubação mineral; T2 = Três aplicações/semana; T3 = Duas aplicações/semana; T4 = Uma aplicação/semana; T5 = Uma aplicação a cada 2 semanas; T6 = Uma aplicação a cada 3 semanas. Foi avaliada a altura de planta, diâmetro do caule, matéria verde e seca da parte aérea da planta bem como do sistema radicular e, teor foliar de macro e micronutrientes. Evidenciou-se que, a fertirrigação com efluente líquido de biodigestor não proporciona alterações significativas no desenvolvimento inicial de cafeeiros em casa de vegetação. Além disso, o uso do efluente líquido de biodigestor proporcionou níveis elevados de N, Ca, Mg, Fe e Mn, acimas dos níveis críticos determinados para a planta.

In modern agriculture, there is a growing need for cropping efficiency e low environmental impacts. Diverse technologies are becoming available in a recent wave of modernization and integration of knowledge. The use of high-efficiency light supplementation to plant development is scarce to high-productive crops at field conditions (outdoor). The objectives of this study were to evaluate soybean plant and yield responses in an open commercial area (field scale) cultivated with artificial light supplementation. A commercial irrigated (pivot) area received an illumination system for light supplementation (LS) in the inner pivot spans. The light applied was a composition of blue, green and red bands. The outer pivot spans did not receive light supplementation (nLS). About 40 hours of LS were applied to the plants during the soybean crop cycle. Internode number, plant height, pods per plant were weekly evaluated to compose the area under the progress curve (AUPC). The grain yield was also evaluated at harvest. Analysis of variance and test of averages were used to evaluate the data. The AUPC of the internode number, plant height and pods per plant were 15.6, 23.3 and 25.3% higher than for the LS treatment. The regular soybean cycle (nLS) was about 17 weeks; however, the harvest of the LS treatment happened three weeks later. The grain productivity of the nLS was about 4,500 kg ha-1 (75 bags), and of the LS treatment was about 7,080 kg ha-1 (118 bags) - 57.3% superior. Light supplementation at field scale is a challenge; however, affordable and field resistant technologies are now accessible. The present study is the first report of light supplementation used to improve soybean crop production at field scale. The possibility of using light regulation as an additional technique for increasing yields and sustainable production are also discussed.

Sugarcane is one of the major alternatives for the biofuel sector and its large production has considerable environmental impacts. Organomineral fertilizers formulated with environmental liabilities such as filter cake and sewage sludge positively affect parameters of plant growth and development. The objective of this study was to evaluate the chemical and technological characteristics of sugarcane fertilized with pelletized organomineral fertilizers based on filter cake and sewage sludge. Eight field treatments were studied, being three levels of organomineral (50, 100, 150%) of two organic matter sources (filter cake, sewage sludge), plus a control with 100% of the recommended fertilization via mineral fertilizer and no fertilization control (0%). Sugarcane was evaluated during two consecutive harvest, and the amount of stalks per hectare (ton ha -1 ), the sugarcane productivity (ton ha -1 ), the quantity of sugar per hectare (TSH, ton ha -1 ), and the chemical and technological analysis of the sugarcane juice: pol (%), brix (%), purity (%) and fiber (%) were evaluated. None of the organomineral sources or doses differed from the exclusive mineral fertilization. The analysis of both harvests indicated that the first cut was the most productive since the responses of the first harvest were superior or similar to the second harvest. The recommended organomineral dose to obtaining maximum quantitative and qualitative sugarcane results was between 102 and 109% of the regular recommendation for mineral fertilization, regardless of the organic source in the first sugarcane harvest. In the second sugarcane harvest, sewage sludge source increase by 4.68 and 4.19% the total amount of sugar per hectare and the quantity of sugarcane compared to the sugarcane filter cake source. Sewage sludge and sugarcane filter cake as sources for organominerals are viable alternatives and advantageous in economic and environmental terms for the cultivation of sugarcane.

The period of implantation of the no-tillage system (NTS) is a fundamental factor to the dimension of the changes that occur to the soil's physical, chemical and biological attributes. Thus, the objective of this study was to evaluate the soil changes to the physical attributes and correlate the results to the soil organic matter in areas of different long-term soil management. The study was set as a completely randomised design, in a 4 × 4 factorial scheme, with four management systems [5 years NTS (NTS5); 17 years NTS (NTS17); conventional tillage system for 20 years (CTS20); native area (NA)], and four soil depths (0-0.05, 0.05-0.1, 0.1-0.2, 0.2-0.4 m), with five repetitions. Soil mechanical resistance to root penetration (RP), bulk density (SD), volumetric moisture (VM), macro (Ma), microporosity (Mi) and total porosity (TP), and the aggregation parameters were evaluated. The CTS20, NTS5 and NTS17 presented superior SD in the most superficial soil layers, which was not yet causing resistance to root development. The SD was the only physical attribute that correlated significantly with all the other soil attributes evaluated, indicating the importance of such attribute to evaluate soil quality to crops. The soil physical attributes found in the Cerrado native area followed the sequence of similarities: no-tillage system with 17 years (most similar), with five years and the conventional tillage system (less similar). The changes caused by the anthropic activity in the soil's physical attributes are more pronounced and perceptible in soil depths up to 0.2 m.

The cultivation of sweet corn is expanding in Brazil, but there are serious constraints about the availability of commercial cultivars. The selection of superior sweet corn genotypes can be performed based on selection indexes based on plant agronomic characteristics. Thus, the objective of this work was to compare selection indexes to select sweet corn genotypes aiming greater productions. The experiment was conducted at the Vegetable Experimental Station of the Federal University of Uberlândia, Campus Monte Carmelo. Eighteen sweet corn accessions (F3 generation) were evaluated. The selection indexes applied to the agronomic characteristics of sweet corn were: direct and indirect, the sum of ranks, desired gains and ideotype indexes. The characteristics evaluated presented significant differences among genotypes, except for stem diameter, prolificacy and grain number per corncob. The coefficients of variation were below 30%, and the genetic parameters were satisfactory for most of the characteristics. The greatest gains with direct selection were in production (21.23%) and productivity of commercial sweet corn ear (15.19%), however, the indirect gains are unsatisfactory for sweet corn selection, and the sum of ranks index provided a balanced distribution of gains. The sweet corn genotypes L2P11, L2P37, P45, L2L5P3, and L5P18 presented a superior performance for the set of characters evaluated.

Wheat production is dependent on costly insecticides that generate social and environmental issues. The growing demand for a rate reduction of spray applications and increased spray efficiency make essential the research for more adequate crop management. Therefore, this study aimed to evaluate technologies of imidacloprid application on wheat aphid, Schizaphis graminum and its natural enemies, Chrysoperla externa and Orius insidiosus. A set of experiments were performed to evaluate the effectiveness of S. graminum control and the toxicity to natural enemies using imidacloprid plus adjuvants sprayed with different nozzles and application rates. Improved S. graminum control was observed in the association between the adjuvant lauryl ether sodium sulfate and the hollow cone nozzle for both application rates (75 and 150 L ha-1), and the adjuvant copolymer of polyester + silicone + d-limonene with the asymmetric twin flat-fan nozzle at a low rate (75 L ha-1), since these treatments eliminate the wheat aphid after the fifth day of treatment application. The reduction of spray volume to wheat aphid control is possible with no loss of insecticide effectiveness. Imidacloprid associated with any one of the adjuvants tested is harmful to C. externa and O. insidiosus, even at the fifth day after application the insecticide continues being harmful to the natural enemies, regardless of the technology used. Key words: Triticum aestivum, Schizaphis graminum, ecological disturbance, insecticide impacts, natural control, neonicotinoid.

Background: The use of electrostatic spray has the potential to optimize pesticide applications; however, further studies are required to verify its effectiveness. Objective: The objective of this work was to evaluate the electrostatic application system for the chemical control of weeds with glyphosate and adjuvant in different carrier volumes. Methods: The physicochemical properties of the spray solution, charge/mass relations, spray deposition on weeds, losses to the soil, effectiveness of weed control, and spray drift were evaluated. The field experiment was designed to have randomized blocks with four replications in a 2x2x2+2 factorial: the presence or not of electrostatic spray; with and without adjuvant (soybean lecithin + propionic acid); two carrier volumes (50 and 90 L ha-1); a control without applications and a conventional spray rate (150 L ha-1) for additional treatments. The study was performed in duplicate. Results: The electrostatic system energized the droplets during the application of glyphosate and adjuvant; however, this did not influence the deposition on the weeds, the losses to the soil, and the drift. The adjuvant improved the effectiveness of weed control in various situations, changed the spray solution properties, and reduced the losses due to drift. Conclusions: The adjuvant used proved to be an important tool in application technology. The effectiveness of weed control, in general, was not influenced by the electrostatic system.

Coffee plants (Coffea arabica L.) present dense foliage that obstruct the entering of pesticides inside the plant canopy uniformly. Adjust the application rate concerning the plant canopy volume can be a way to make the pesticide applications more efficient. The objective of this study was to evaluate the deposition of spray solution on coffee leaves with different volumes of plant canopy and different application rates; additionally, to determine the specific volume indexes for different coffee phenological stages. The studies of coffee leaf deposition were performed on commercial fields of C. arabica - Topázio MG 1190 and Catuaí Vermelho IAC 99 cultivars, in different months. Three volumes of vegetation ranging from 8.572 to 16.200 m3 ha-1 - obtained from the calculation of tree-row volume (TRV) performed in 20 plants - and five application rates (200, 300, 400, 600 and 800 L ha-1) and in each phenological stage (maturation, post-harvest, grain filling) were evaluated in a randomized block design with five replications. A bright blue marker was added to the spray solution to be detected by spectrophotometry in order to study the spray deposition and losses to the soil. After the treatment applications, ten coffee leaves corresponding to the 1st pair of leaf from an orthotropic branch of each third of the coffee plant (upper, middle, lower) were randomly collected. Petri dishes were used to evaluate the losses to the soil. The TRV and leaf density should be considered together in the definition of the application rate for coffee protection. It is also possible to reduce the application rate to values close to 200 L ha-1. The volume indexes for each coffee phenological stage were defined for proper canopy wetting and low losses to the soil.

Hevea brasiliensis natural rubber production is strategic for the world economy. Meloidogyne exigua causes the main root disease in this crop in Brazil. Its early diagnosis allows better pest management, reducing losses. This study aimed to identify rubber tree orchard areas infested by M. exigua using remote sensing and vegetation spectral indices—normalized difference vegetation (NDVI) and simple ratio (SR)—generated from the RapidEye® satellite constellation images. Orchards under tapping in Minas Gerais state (irrigated) and Goiás state (without irrigation) were sampled during the rainy season and soil, root and total nematode density were estimated. Although significant interactions between nematode density and vegetation spectral indices were found, none had determination coefficient (R2) greater than 0.31. Descriptive statistics of both orchards did not identify differences between the areas and root or total nematode density; however, nematode density in the soil in the Goiás orchard was 236% greater than in the Minas Gerais orchard, while both spectral vegetation indices were lower in the former. Such differences might be a consequence of irrigation. Pearson’s, Spearman’s and Kendall’s correlations between nematode density and NDVI presented greater coefficients than SR for every parameter in both orchards. NDVI can be used to distinguish non-infested rubber tree orchard from one infested by M. exigua.

RESUMO Com a finalidade de se conhecer melhor sobre o manejo de Meloidogyne exigua na cultura da seringueira, foram testados em campo dois métodos de controle, o químico e o biológico, da Morte Descendente da Seringueira. Assim, neste trabalho, objetivou-se avaliar a resposta de seis tratamentos: T1 – Testemunha, T2 - Paecilomyces lilacinus + Trichoderma harzianum (300 g ha-1 de cada), T3 - Trichoderma asperelloides (1 g L-1) + Bacillus subtilis (1 mL L-1) + Bacillus methilotrophicus (2 mL L-1), T4 – Cadusafós (15 L ha-1), T5 – Bacillus subtilis + Bacillus licheniformis (1,0 a 1,5 kg ha-1) e T6 -Fluensulfone (3 L ha-1), e seus potenciais de ação sobre este nematoide. Além disso, verificou-se também se houve aumento da produção de látex com os tratamentos e se há relação entre infestação e incremento diamétrico das árvores. O experimento foi conduzido em uma fazenda localizada no Triângulo Mineiro, MG. O experimento foi instalado em delineamento em blocos casualizados, com seis tratamentos e cinco repetições. Foram realizadas quatro amostragens para determinação da densidade populacional do nematoide em pré e pós aplicações, até 30 dias após a última aplicação. As amostras foram acondicionadas em sacos plásticos e levadas ao Laboratório de Nematologia da Universidade Federal de Uberlândia para o processamento. Foram avaliados o fator de reprodução, a produtividade de látex e o diâmetro médio das árvores. De todos os tratamentos utilizados, o T5 e T2 demonstraram redução do fator de reprodução em comparação aos demais. Nenhum dos produtos demonstrou eficiência quanto às três características de produtividade avaliadas: kg ha-1, kg árvore-1 e kg parcela-1, indicando que ainda não se justifica a recomendação dos produtos para esta característica. Os diâmetros médios das parcelas também não foram influenciados pelos tratamentos utilizados.

The decomposition of plant residues, the changes in the total organic carbon (TOC) and the fractions of soil organic matter (SOM) occur differently in irrigated areas. The objective of this study was to quantify the biomass production, the decomposition of cover crops residues and relate them with the changes n the content and fractions of SOM in an irrigated area of vegetable crops. Six types of cover crop treatments were evaluated: brachiaria (B); sunn hemp (S); millet (M); B + S; B + M; S + M, plus an additional treatment (native area), with 4 repetitions. The production of fresh (FB) and dry biomass (DB), the rate of plant residue decomposition, TOC, SOM fractions and the coefficient of SOM (QSOM) were quantified. It was observed that the greatest and the lowest volume of crop residues were from the B and S cover crop, respectively. The cover crops in monoculture presented great decomposition rates and short half-life when compared to mixtures of cover crop. The TOC and QSOM were great in the 0 to 0.05 m soil layer, and in the M + S cover crop mixture, when compared to the 0.05 to 0.1 m soil layer and to other cover crops. Among the SOM fractions, the humin predominated in the most superficial soil layer (0 to 0.05 m).

This study analyzed the use of the water balance, precipitation, temperature and NDVI (Normalized Difference Vegetation Index) to determine the optimum moment for evaluating infestation by the nematode Meloidogyne exigua in a rubber tree plantation by remote sensing. Nineteen sampling points were defined, divided into three areas, with high and low defoliation degrees, on a property in the Triângulo Mineiro region, where soil and root samples were collected for nematological analysis. Monthly digital images (OLI - Landsat 8 sensor) were obtained from August 2015 to August 2016. Rainfall, temperature and water balance were analyzed. The latter had no correlation with the indices; in contrast, temperature and precipitation correlated directly with NDVI. The best months for nematode soil infestation analysis were December, January and February, while for root infection it was August.
