 In order to maximize the productivity of forest species, techniques such as irrigation have been used. The objective of this study was to evaluate the water use efficiency and the influence of the irrigation located in the growth of the hybrids of eucalyptus Grancam and Urograndis at 65 months. The study was carried out in the experimental area of the State University of Mato Grosso do Sul (UEMS), in Aquidauana (state of Mato Grosso do Sul, Brazil). The experimental design was randomized blocks with subdivided plots. The treatments used in the plots were two irrigation systems (microsprinkler and drip) and one control treatment with no irrigation (dryland), and in the subplots, the two hybrids of eucalyptus: Grancam (Eucalyptus grandis x Eucalyptus camaldulensis) and Urograndis (Eucalyptus urophylla x Eucalyptus grandis), submitted to irrigation up to the 53° month after planting (MAP). The results were submitted to the analysis of variance and the Tukey test for means comparisons at 5% of probability. The use of irrigation in eucalyptus influences the productivity, providing increased wood volume, height of plants and diameter at breast height (DBH). The hybrid Grancam showed greater increase in height, and Urograndis increased in DBH. The higher efficiency of water use for the volumetric production of wood was observed in drip irrigation for the hybrid Grancam. The hybrid Urograndis is more efficient in the use of water for the volumetric production of wood regardless of the treatment.

O objetivo desse trabalho foi a geração de um mapa de aptidão florestal considerando níveis de manejo para Eucalyptus camaldulensis Dehn, Eucalyptus citriodora Hook, Eucalyptus grandis W. Hill ex Maiden e Eucalyptus urophylla St. Blake na bacia do rio Dourados, com auxílio do software SPRING 4.1/INPE. A área de estudo localiza-se no estado de Mato Grosso do Sul, entre as coordenadas 21º 56’ S - 22º 38’ S e 53º 57’ O - 55º 57’ O, com precipitação média anual na região em torno de 1.400 mm e clima do tipo Cwa. Os solos são predominantemente da classe Latossolos, ocorrendo também Argissolos, Neossolos Quartzarênicos e Gleissolos em menores proporções. As exigências edafoclimáticas das espécies citadas foram baseadas na sua ocorrência nas regiões de origem. A partir do cruzamento dos mapas de solos, altimetria, hidrografia, declividade, áreas de preservação permanente e de uso da terra, e considerando-se as restrições para cada espécie, geraram-se três mapas: um para E. urophylla, outro para E. camaldulensis, E. citriodora e E. grandis e um terceiro considerando os níveis de manejo tecnológico. Como resultado, constatou-se que mais de 87% (excetuando-se a reserva legal) da área da bacia do rio Dourados é apta para o cultivo das espécies consideradas, podendo-se contar com sete classes de manejo tecnológico.

O objetivo deste trabalho foi avaliar o desenvolvimento inicial de dois híbridos de eucalipto (Grancam e Urograndis), irrigados por gotejamento e microaspersão e sem irrigação dos 7 aos 17 meses após o plantio (MAP). O experimento foi instalado na área experimental de irrigação da Universidade Estadual de Mato Grosso do Sul, no município de Aquidauana - MS. O delineamento experimental utilizado foi blocos casualizados, em parcelas subdivididas, com quatro blocos e duas replicações dentro de cada bloco, sendo as parcelas compostas pelos tratamentos de irrigação (gotejamento, microaspersão e sequeiro) e as subparcelas pelos híbridos (Grancam e Urograndis). Foi avaliada a altura de plantas, o diâmetro de caule, a área basal de caule, a relação entre altura e diâmetro de caule, volume de caule por hectare e incremento médio mensal das variáveis analisadas. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste Tukey em nível de 5% de probabilidade de erro. Em todos os meses os sistemas de irrigação por gotejamento e microaspersão propiciaram maior altura de plantas, diâmetro do caule, área basal do caule e volume de caule por hectare. O híbrido Grancam apresenta parâmetros dendrométricos superiores ao Urograndis.

A cultura do Eucalipto é de apresenta importância econômica para o Brasil, principalmente para o estado de Mato Grosso do Sul, onde possuí 16% de áreas plantadas. A atual busca por qualidade e produtividade na eucaliptocultura deve passar por delimitações de áreas agroclimaticamente aptas ao cultivo. Nesse sentido foi realizado o zoneamento agroclimático para o cultivo de Eucalyptus camaldulensis, Eucalyptus grandis, Eucalyptus urograndis, Eucalyptus urophyla, Corymbia citriodora para o estado de Mato Grosso do Sul, utilizando técnicas de geoprocessamento. Foram utilizados 97 estações pluviométricas e 15 estações meteorológicas do estado e regiões circunvizinhas para especializar a precipitação, temperatura e déficit hídrico e depois reclassificá-las para a geração do zoneamento agroclimático. De acordo com os resultados obtidos, o estado apresenta áreas com aptidão agroclimáticas para todas as espécies de Eucalyptus, sendo que a espécies E. camaldulensis apresenta a maior área de aptidão quando comparado com as demais, podendo ser cultivado em 64,5% do estado. Para as espécies E. urophylla e E. urograndis, as áreas propícias para sua implantação são similares, contudo, a área com aptidão para o E. urophylla é mais abrangente, pois é possível cultivar estas espécies em temperaturas mais elevadas e com maior déficit hídrico. O E. grandis e C. citriodora apresenta menor áreas de aptidão principalmente por serem exigentes a temperaturas mais baixas.

Hemarthria Compressa

Water stress is an important approach to use water resources efficiently and remit the agricultural water shortage. Hemarthria compressa is one of perennial grasses, a pasture of high quality, which has abundant species resources in China. To explore the response of the growth, yield and water use efficiency(WUE) of Hemarthria compressa under water stress, this study, adapting pot experiment, imposed three water stress degree (LD, MD and SD) treatments and a control treatment on Hemarthria compressa. The data of growth indicators during control period, yield and total water consumption were obtained. The results show a noticeable inhibitory action of water stress on the growth of Hemarthria compressa. Along with the intensifying of water stress, plant height increment, leaf area, total biomass, dry matter of each organ and yield decreased, and the root-shoot ratio increased firstly and inclined to slump finally. Plants under the middle water stress treatment achieved the greatest WUE of 38.25 kg/m3. The first 10d in the water control period was the most sensitive period of the pasture responding to water stress.

Growth Of Seedlings

The seedling quality affects the plant performance in the field and proper techniques can increase the productivity of vegetables. The objective of this study was to evaluate the production of eggplant seedlings, cultivar Embu, under protected environments, containers and substrates, and its development in the field at the State University of Mato Grosso do Sul, in Aquidauana, Brazil. For seedlings production, each environment was considered an experiment, which was carried out in a completely randomized design, in split-plot scheme (containers x substrates), with eight replications. Subsequently we realized joint analysis of the experiments to compare the environments. In the field, the design was in randomized blocks using four replications. The seedlings were grown in the protected environments: greenhouse covered with polyethylene film, light diffuser, 150 micron, and nursery monofilament screen with 50% of shading (Sombrite®). Inside environments, polystyrene trays with 72 cells and 128 cells were tested. The containers were filled with six substrates, from the combination of cattle manure and cassava stems. In the field were distributed 24 treatments generated from combinations of three factors. In both environments, the best seedlings are formed in trays with 72 cells. For two trays the best seedlings are formed in the greenhouse. In greenhouse, the substrate with 80% cattle manure and 20% of cassava stems promoted better growth of seedlings. In the screened, beyond this substrate, seedlings produced in the substrate with 100% manure showed higher vigor. For all substrates, the best seedlings are formed in tray with 72 cells inside the greenhouse. In the field the combination, "greenhouse + 72 cell tray + 80% manure and 20% cassava stems" was where the plants had better growth and productivity.

The okra grows well in hot weather, finding favorable conditions for development in Brazil. We evaluated the production of okra seedlings and productivity. The experiment was conducted in the experimental area of the State University of Mato Grosso do Sul, in Aquidauana. In the seedling phase we tested substrates (100% triturated cassava stems, 75% triturated cassava stems and 25% vermiculite, 50% triturated cassava stems and 50% vermiculite, 25% triturated cassava stems and 75% vermiculite and 100% vermiculite). These substrates were placed in two protected environments (nursery with black screen, 50% of shading, and aluminized screen, 50% of shading). Each environment was considered an experiment conducted in completely randomized design with eight replications. After that we realized joint analysis. In the field, a total of 10 treatments generated from combinations of environments and substrates (2 environments x 5 substrates) were distributed in a randomized block design with four replications. The average proportions of cassava stems and vermiculite may be suitable for okra seedlings. The results of shoot and total dry phytomass indicate that the aluminized screen can be recommended for okra seedlings production when the substrate with a 1:1 ratio is used. Seedlings grown on higher percentages of vermiculite anticipate production, while seedlings produced only in cassava stems tend to slow it down. The aluminized screen tends to increase the yield of okra seedlings. Average proportions of vermiculite and cassava stems for seedling production under aluminized screen, provide more fruits and yield of okra in Aquidauana.

The work Discursive memory on gender violence in the voice of women with disabilities originated from the Master of Arts in Literature research developed by Flávia Pieretti Cardoso, under the guidance of professors Maria Leda Pinto and Léia Teixeira Lacerda, at the State University of Mato Grosso do Sul. In her role as an interpreter of Brazilian Sign Language at the Casa da Mulher Brasileira and her experience with women from the Association of Women with Disabilities of Mato Grosso do Sul, Flávia was concerned about the invisibility and lack of accessible data and information in the area of gender and disability. The concern resulted in this book, which analyses the speeches of women with disabilities living in Campo Grande / MS, from the theme of gender violence in order to seek possibilities to implement actions to face this type of violence. The theoretical path is based on qualitative research and the corpus analysis grounded on French Discourse Analysis (FDA) studies, as well as on scholars from the Bakhtin Circle, on the analysis of texts of oral communication and the gender and violence area. The analyses presented will enable the reader to conclude that girls and women with disabilities are subject to double exclusion and vulnerability – for having a disability and for being women – by the sexist and capacitist speeches of “power” and “truth”. Therefore, it is a matter of urgency that the Brazilian authorities of power implement effective public programs and policies aimed at the specificities of those subjects.

ABSTRACT The quality of seedling is critical to obtain vigorous plants in the field. The present study aimed to assess biomasses and biometric relations of soursop seedlings. We used different substrates in protected environments. The experiment was performed at the Universidade Estadual do Mato Grosso do Sul (UFMS) (State University of Mato Grosso do Sul). Five farming environments were developed in greenhouses: one covered with low-density polyethylene film (LDPE), another with with polyethylene and heat-reflective cloth under film under 50% shading in aluminized color, monofilament cloth under 50% shading in black, thermo-reflective cloth under 50% shading in aluminized color, and an environment covered with bacuri coconut straw. Substrates were made of manure, humus, cassava branches and vermiculite at different proportions. Each of them varying from 25%, 33.3%, 50% and 75% in mixture combination. Each environment was considered an experiment. A completely randomized design was adopted and later a joint analysis of them. Agricultural greenhouse covered with LDPE and thermo-reflective cloths under 50% of shading, proportionated seedlings with greater biomass. Substrates containing manure are the most suitable for soursop seedlings. High percentages of earthworm humus produce low quality soursop seedlings. Soursop seedlings had a Dickson’s quality index around 0.335. The greenhouse covered only with LDPE film did not produce high quality seedlings.

Winter Wheat Varieties

The effects of simulated waterlogging, drought stress and their combination were examined in a model experiment in Martonvásár, Hungary, in 2018. Four modern winter wheat varieties (‘Mv Toborzó’ (TOB), ‘Mv Mambó’ (MAM), ‘Mv Karizma’ (KAR), ‘Mv Pálma’ (PAL)) and one old Hungarian winter wheat cultivar (‘Bánkúti 1201’ (BKT)) were tested. Apart from the control treatment (C), the plants were exposed to two different abiotic stresses. To simulate waterlogging (WL), plants were flooded at four leaf stage, while in the WL + D treatment, they were stressed both by waterlogging and by simulated drought stress at the early stage of plant development and at the heading stage, respectively. The waterlogging treatment resulted in a significant decrease in plant biomass (BKT, TOB), number of spikes (TOB), grain yield (BKT, TOB), water use (BTK) and water-use efficiency (TOB, MAM, PAL) compared to the controls. The combined treatment (WL + D) led to a significant decrease in plant height (BTK, MAM, KAR), number of spikes (BTK, TOB, MAM, KAR), thousand kernel weight (TOB), harvest index (BTK), biomass, grain yield, water-use efficiency (in all varieties) and water use (BKT, TOB, MAM, KAR) of the plants. The best water-use efficiency was observed for MAM; therefore, this genotype could be recommended for cultivation at stress prone areas. The varieties MAM, KAR and PAL also showed good adaptability.
