Phytoremediation, the use of plants to decontaminate soils and water resources from organic pollutants such as herbicides, is economically and environmentally a promising technique applied in many areas, including agriculture. The objective of this work was to evaluate the development of bean plants cultivated in the field, in soil with different levels of trifloxysulfuron-sodium contamination, following cultivation of two green manure species, as well as to evaluate the possibility of recontamination of the area by such herbicide with the straw permanence on the soil. The experiment was carried out in Coimbra, MG, Brazil, on a sandy clayey Red - Yellow Argisol from March to November 2003. Four levels of soil contamination with trifloxysulfuron-sodium (0.00; 3.75; 7.50; and 15.00 g ha-1) were used as well as the following five types of cultivation prior to bean sowing in the area after herbicide application: black velvet beans (Stizolobium aterrimum) followed by removal of straw; S. aterrimum, followed by permanence of straw; jack bean (Canavalia ensiformis), followed by removal of straw; C. ensiformis followed by permanence of straw; and without prior cultivation, weed-free (weeded control). The leguminous plants were kept in the area for 65 days, cut close to the soil, and with its aerial part left or not on the surface of the experimental plot, depending on the treatment. Fifteen days after the species were cut, bean was sown in the area. At 45 days after emergence (DAE) of the bean plants, plant height and dry mass of the aerial part were evaluated. Grain productivity was determined during harvest. Height, dry matter of the aerial part and grain productivity of the bean plants, cultivated in an area previously contaminated with trifloxysulfuron-sodium at any of the levels tested, were higher with prior cultivation of S. aterrimum or C. ensiformis. At the lowest level of herbicide contamination, prior cultivation of C. ensiformis was found to be more efficient than that of S. aterrimum in mitigating the harmful effects of trifloxysulfuron-sodium on bean grain production. The permanence of the straw of the green manure species during the bean cycle did not harm the development of the plants or caused culture productivity losses, indicating that straw permanence in the area does not promote recontamination of the area.

Nesta direção, buscou-se avaliar a produção da biomassa e analisar a distribuição de fotoassimilados da mamoneira (BRS Energia) irrigada com águas salinas (CEa = 0,6; 1,6; 2,6; 3,6; e 4,6 dS m-1) e adubada com doses de nitrogênio (50; 75; 100, 125 a 150 mg kg-1 de solo). Os fatores testados foram alocados em blocos casualizados, em esquema fatorial 5x5, com três repetições, totalizando 75 unidades experimentais. Os dados obtidos foram submetidos à análise da variância pelo teste ‘F’ e comparados mediante análise de regressão em 0,01 nível de probabilidade. Verificou-se que até CEa = 3,6 dS m-1 houve maior produção de massa seca da parte aérea sob 125 mg de N kg-1 de solo e que nas condições de salinidade impostas às plantas, as folhas foram a maior fonte e o racemo o maior dreno da parte aérea, bem como a alocação de fotoassimilados na raiz foi até 59,75% maior que na parte aérea.   Palavras-chave: Ricinus communis L., salinidade, adubação nitrogenada     ALVES, A.

ABIOTIC FACTORS AND DISTRIBUTION OF PHOTOASSIMILATES IN CASTOR BEAN PLANTS UNDER SEMIARID CONDITIONS       2 ABSTRACT   Although the susceptibility to abiotic factors is obvious, the analysis of photoassimilates in plants under stress is relevant to subsidize management practices. In this context, the production of biomass and partition of photoassimilates of castor bean (BRS Energy) irrigated with saline water (ECw = 0.6, 1.6, 2.6, 3.6, and 4.6 dS m -1) and fertilized with nitrogen (50; 75; 100, 125 to 150 mg kg-1 of soil) was evaluated. The factors tested were allocated in randomized blocks in a 5x5 factorial design with three replications, totaling 75 experimental units, and the data were submitted to analysis of variance by the ‘F’ test and compared by regression analysis at 0.01 level of probability. It was verified that up to ECw = 3.6 dS m-1 there was greater dry mass production of shoot under 125 mg of N kg-1 of soil. In the conditions of salinity imposed to the plants, leaves were the greater source and racemus was the greater drainage of the aerial part, as well as the allocation of photoassimilates in the root was up to 59.75% higher than in the aerial part.   Keywords: Ricinus communis L., salinity, nitrogen fertilization

Summary Inoculation of symbiotic N2-fixing rhizobacteria (rhizobia) in legumes is an alternative to reduce synthetic N fertiliser input to crops. Even though common bean benefits from the biological N2 fixation carried out by native rhizobia isolates, the low efficiency of this process highlights the importance of screening new strains for plant inoculation. Two rhizobial strains (SEMIA 4108 and SEMIA 4107) previously showed great potential to improve the growth of common beans under greenhouse conditions. Thus, this study evaluated the growth and grain yield of common bean plants inoculated with those strains in field experiments. The rhizobial identification was performed by 16S rRNA sequencing and the phylogeny showed that SEMIA 4108 and SEMIA 4107 are closely related to Rhizobium phaseoli, within a clade containing other 18 Rhizobium spp. type strains. Common bean plants inoculated with SEMIA 4107 showed similar productivity to N-fertilised (N+) plants in the first experiment (2016/17) and higher productivity in the second experiment (2018/19). The development of inoculated plants was different from that observed for N+. Nonetheless, comparing inoculated treatments with N-fertilised control, no yield or productivity losses at the end of the growing process were detected. Our results showed that inoculation of the rhizobial isolates SEMIA 4108 and SEMIA 4107 improved the growth and grain yield of common bean plants. The observed agronomical performance confirms that both strains were effective and can sustain common bean growth without nitrogen fertilisation under the edaphoclimatic conditions of this study.

A trial was carried out in Campinas, Brazil, from August 2005 to August 2006, in order to analyze the effect of two propagation methods (seeds and cuttings) on the development of Pfaffia glomerata (Spreng.) Pedersen. The experimental design was a completely randomized block, with five replications, and two methods of plant propagation. Plant height, aerial part dry mass and root dry mass were evaluated. Plants propagated from cuttings showed greater accumulation of dry mass on the aerial part. Root dry mass accumulation curves showed an exponential pattern, and at the end of the experimental period, the average of roots dry mass for both treatments were similar, up to 349,65 g plant-1.

The experiment was conducted in a greenhouse at the Universidade Federal do Espirito Santo, in Alegre, Espirito Santo state, Brazil, to evaluate the broccoli production depending on the seed production system and organic and mineral fertilization. Seeds of the broccoli cultivar Ramoso Piracicaba were originated from lots of seed obtained in an organic and conventional production system. The experimental design was of randomized blocks, with four replications in a factorial arrangement combination of the lots, 2x5 (organic and mineral fertilized seeds) and substrates [S1 (soil + sand + manure), S2 (soil + sand + manure + NPK), S3 (soil + sand + manure + Fertium® 10 g L-1), S4 (soil + sand + manure + Fertium® 30 g L-1) and S5 (soil + sand + manure + Fertium® 50 g L-1]. The analyzed variables were emergency, fresh and dry mass of aerial part, emergency speed and height of seedlings after 28 days of sowing, and plant diameter, leaf area, number of leaves, fresh and dry mass of aerial part, plant height, root volume, fresh and dry root mass, absolute and relative growth rates and increment to leaf area and plant height after 104 days. The emergency was similar in the different substrates; great vigor occurred on conventional seeds; the mineral fertilization increased the production of fresh mass of aerial part; the use of substrate containing soil, sand soil conditioner Fertium (30 to 50 g L-1) increased the volume, fresh and dry mass of roots and rate of increase in these variables.

ABSTRACT: The aim of this study was to evaluate the effect of the sowing periods in production, productivity component and physiological quality of seeds of three soybean cultivars (TMG133RR, P98Y70RR and NS7670RR) in Orthic Quartzarenic Neosoil in the cerrado region. The design used was a randomized block a factorial scheme design with four repetitions, and each plot with useful space consisted of three rows of four meters length, spaced at 0.45 meters. Field evaluations were the final stand, the height of the plants, height of the first pod insertion, the mass of 100 seeds and productivity. Already in the lab seeds were evaluated for germination and vigor (first germination count, emergency, emergence speed index, length and dry mass of the aerial part of the plant and roots, electrical conductivity, accelerated aging and tetrazolium test). It concludes that it is possible to use Orthic Quartzarenic Neosoils, located in the Cerrado region at altitudes higher than 600 m, in years and places with good water distribution in the spring-summer seasons, for grain and soybeans production, but as a first goal, the crop should be sown in the first 20 days of November otherwise it should take place in early December.

The objective of this work was to evaluate the productive performance of broccoli under different top-dressing organic fertilizations. The experiment was conducted under protected cultivation, in a completely randomized design with four replications, with two plants per experimental unit. Broccoli seedlings were produced in a commercial substrate in styrofoam trays. The seedlings were transplanted to plastic pots containing 10.0 L of substrate made up of subsoil and organic compost at the ratio of 3:1 (v/v), respectively, which is equivalent to about 20.0 t ha-1 of organic compost at planting. After seedling establishment, the top-dressing fertilization treatments were applied: gliricidia biomass associated or not with liquid biofertilizer of cattle manure to the soil and bokashi. Two control treatments were established: one with mineral fertilization recommended for the crop and the other without top-dressing fertilization. The broccoli production was evaluated (commercial standard). Plants that received mineral fertilizer were more productive, however, they were not significantly different (p>0.05), by Dunnet test, from the plants fertilized with 2.5 t ha-1 gliricidiabiomass (dry mass) associated with liquid biofertilizer (2.0 L m-2) applied to soil. Top-dressing fertilizations with only gliricidia, at 2.5 and 5.0 t ha-1 of biomass (dry mass), resulted in no significant increase in production of broccoli inflorescence. The use of bokashi in addition to gliricidia biomass and liquid biofertilizer reduced the efficiency of the fertilization compared with plants that received only gliricidia and liquid biofertilizer.

The aim of this work was to evaluate the growth of two clones of Eucalyptus saligna on salt-stress mediated by NaCl in hydroponics. Micropropagated plants of the clones p0 and p1 were acclimatizated and cultivated in hydroponics at 0 and 300 mM NaCl levels. The total length, volume, number, fresh mass and dry mass of the roots, the height, fresh and dry mass of the aerial part and the fresh  and dry mass of the complete plant were evaluated to the 14 days of hydroponic culture with NaCl. There were significant differences among the clones. The clone p0 was superior to the clone p1 in relation to volume of the roots, root number, root fresh mass and total fresh mass of the root. Regards the effect of the salinity on the plants, significant reduction was observed in the height of the aerial part, fresh mass of the aerial part and the total fresh mass. Even so, the interaction between the clones and the concentrations of NaCl was significant for the total fresh mass. In the period of 14 days of hydroponic culture on 300 mM NaCl was possible to discriminate these two clones in relation to the tolerance and susceptibility to the salt stress. The clone p0 presented higher growth and larger tolerance to the salinity than clone p1.

O meloeiro tem grande importância econômica para o Nordeste brasileiro. Entretanto, em seu cultivo utiliza-se insumos que podem prejudicar o ambiente; como, os fertilizantes nitrogenados. Objetivou-se avaliar a emissão de N2O em cultivo de meloeiro amarelo ‘Goldex’. O experimento foi instalado em delineamento inteiramente casualizado, com cinco repetições. Os tratamentos foram: 0 (controle), 1,0; 1,5 e 2 vezes a quantidade de nitrogênio recomendada para cada estádio. Foi analisado o fluxo de N2O, área foliar, número de folhas, massa seca da parte aérea, massa seca dos frutos, massa seca da parte radicular, nitrogênio total do solo, das plantas e N (NH4+ e NO3-) do solo. O fluxo de N2O teve comportamento temporal irregular durante a fase de plântulas e crescente na floração. Os tratamentos afetaram significativamente a área foliar, número de folhas, massa seca da parte aérea, massa seca da parte radicular, nitrogênio da parte aérea e parte radicular das plantas e do solo. A aplicação de nitrogênio, em dosagens superiores à recomendada, não aumentou a produção do meloeiro. E o cálculo do fator de emissão mostrou que a emissão do N2O não atingiu valores prejudiciais ao ambiente.Palavras-chave: fator de emissão, efeito estufa e nitrogênio. NITROUS OXIDE EMISSION ASSOCIATED WITH UREA USE THE YELLOW MELON CROP ABSTRACT: The melon has great economic importance for the Brazilian Northeast. However, in its cultivation uses inputs that can harm the environment; Such as nitrogen fertilizers. The objective of this study was to evaluate the emission of N2O in yellow 'Goldex' cultivar. The experiment was installed in a completely randomized design with five replications. The treatments were: 0 (control), 1.0; 1.5 and 2 times the amount of nitrogen recommended for each stage. N2O flux, leaf area, leaf number, shoot dry mass, fruit dry mass, dry mass of the root portion, total soil nitrogen, of the plants and N (NH4 + and NO3 -) of the soil were analyzed. The flow of N2O had irregular temporal behavior during the seedling phase and increased in flowering. The treatments affected significantly the leaf area, number of leaves, dry mass of the aerial part, dry mass of the root part, nitrogen of the aerial part and root part of the plants and the soil. The application of nitrogen, in dosages higher than the recommended one, did not increase the production of the melon. And the calculation of the emission factor showed that the emission of N2O did not reach values harmful to the environment.Keywords: emission fator, greenhouse and nitrogen.

ABSTRACT Green manure may lead to physical, chemical, and biological improvements to the soil. However, the information on its use in the Brazilian Northeast is scarce. The aim of this study was to assess the phenological cycle and phytomass productivity of seven legume species. This study was conducted in the second semester of 2015 in a completely randomized design with seven treatments and four replications. Plant height, fresh mass of shoot (FMS), dry mass of shoot (DMS), fresh mass of root (FMR), and dry mass of root (DMR) were determined at 100 days after sowing. Germination, flowering, and pod maturation were also assessed. The highest averages of FMS were observed in Crotalaria breviflora and Crotalaria mucronata, followed by Canavalia ensiformis, whereas the highest averages of DMS were observed in C. breviflora, C. ensiformis, C. mucronata, and Cajanus cajan cv. IAPAR 43. The highest averages of FMR were obtained by C. breviflora and C. mucronata, followed by C. cajan cv. Fava Larga. The species C. mucronata, C. cajan cv. IAPAR 43, and C. breviflora presented the highest averages of DMR. In addition, C. juncea, C. ensiformis, and C. cajan cv. IAPAR 43 were the earlier species regarding flowering, while C. cajan cv. Fava Larga was the later species. C. juncea was the earliest among all studied species regarding pod maturation. The tested legume species obtained promising initial results during the assessment period, being able to meet the expectations of biomass production and contributing to soil sustainability in this region.
