A adubação nitrogenada na cultura da soja, associada a inoculação com a bactéria Bradyrhizobium japonicum é uma prática comum na agricultura, no entanto, muito contestada. Objetivou-se neste estudo avaliar a resposta da soja à aplicação foliar de N em diferentes estádios fenológicos e à aplicação de inoculante com Bradyrhizobium japonicum. O experimento foi realizado em casa de vegetação da Universidade do Estado de Mato Grosso, Alta Floresta-MT. Foi utilizado o delineamento experimental inteiramente casualizado em arranjo fatorial 4x2, sendo quatro épocas de aplicação de nitrogênio (R1 - Início de floração, R3 - Final da floração, R5.1 - Grãos perceptíveis ao tato e R5.3 - Maioria das vagens entre 25-50% de granação) e presença ou ausência de Bradyrhizobium japonicum, com quatro repetições. Conclui-se que a aplicação de nitrogênio foliar na cultura da soja no estágio R1 proporcionou aumento no acúmulo de nitrogênio na parte aérea, no número de vagens e de grãos por planta. A presença do inoculante proporcionou maior número de vagens quando aplicou se N nas épocas R1 e R3, já para a matéria seca de parte aérea, o melhor resultado foi obtido, quando o N foi aplicado em R 5.3, na ausência do inoculante.Palavras-chave: adubação nitrogenada, fixação biológica, inoculante. LEAF APPLICATION OF NITROGEN IN DIFFERENT PHENOLOGICAL STAGES IN SOYBEAN AND INOCULATION WITH Bradyrhizobium japonicum ABSTRACT:Nitrogen fertilization in soybean crop, associated with inoculation with a bacterium Bradyrhizobium japonicum is a common practice in agriculture, however, much contested. The objective of this study was to evaluate the response of soybeans to foliar application of N in different stages of phenology and the application of inoculant with the diazotrophic bacterium Bradyrhizobium japonicum. The experiment was carried out in a greenhouse at the State University of Mato Grosso, Alta Floresta-MT. The completely randomized experimental design was used in a 4x2 factorial arrangement, with 4 nitrogen application times (R1 - Beginning of flowering, R3 - Final flowering, R5.1 - Grains perceptible to touch and R5.3 - Most pods between 25 -50% granulation) and presence or absence of Bradyrhizobium japonicum, with 4 replicates. It was concluded that the application of leaf nitrogen in the non-stage soybean crop provided an increase in the accumulation of nitrogen in the aerial part, there is no number of pods and grains per plant. The presence of the inoculant provided a larger number of pods when applicable. N in the periods R1 and R3, and for the aerial part dry matter, the best result obtained when it was obtained in R 5.3, in the absence of the inoculant.Keywords: nitrogen fertilization, biological fixation, inoculant.

Nitrogen is the element most demanded by the soybean crop, and the biological fixation of atmospheric nitrogen is the main means to supply it. In contrast, micronutrients and chemical treatments applied on seeds together with the inoculant can alter the phenomenon of biological fixation of atmospheric nitrogen. This work aimed to evaluate the effect of chemical products, micronutrients, and nitrogen fertilization on the nodulation, development, and yield of soybean. The experiment was developed in a field and a greenhouse in the municipality of Toledo, Brazil. A randomized block with four repetitions was used as an experimental design. This design had eight treatments, namely: T1 - Control (seeds treated with insecticide); T2 - Seeds treated with insecticides and inoculated with Bradyrhizobium; T3 - Untreated seeds inoculated with Bradyrhizobium; T4  Seeds treated with insecticides and cobalt-molybdenum (CoMo), inoculated with Bradyrhizobium; T5 - Seeds with CoMo inoculated with Bradyrhizobium; T6 - Seeds treated with insecticides, inoculated with Bradyrhizobium and with foliar application of CoMo; T7 - Seeds treated with insecticides, inoculated with Bradyrhizobium and with the application of nitrogen in cover; T8 - Seeds treated with nitrogen by broadcast. No significant differences were observed between treatments on the nodules numbers, stem diameter, plant height, root length, the mass of 1000 grains, and yield. The application of nitrogen at the R2 stage (a plant with an open flower in one of the two uppermost nodes of the main stem with a fully developed leaf) and in association with the inoculant + CoMo without seed treatment provided a greater number of nodes, pods, and grains per plant.

The objective was to evaluate the quality of ornamental pepper seedlings, cultivar Pyramid, in different substrate volumes, with foliar application of paclobutrazol (PBZ).The experiment was carried out at the Mato Grosso do Sul State University - UEMS, in Cassilândia - MS. The experimental design was completely randomized, in a 2 x 2 factorial scheme (growth container x foliar application of PBZ) with four replicates of 36 seedlings each. Plastic trays (cells with a volume of 50 mL) and polystyrene trays (Isopor®, 100 mL cells) were used as containers. The treatments were: polystyrene tray with PBZ application; polystyrene tray without PBZ application; plastic tray with PBZ application and plastic tray without the application of PBZ. Plant height, root length, stem diameter, shoot dry mass, root dry mass, total dry mass, height/stem diameter ratio (H/D), shoot/root ratio (S/R) and Dickson quality index were evaluated. Foliar application of paclobutrazol resulted in robust pepper seedlings with reduced size, suitable and desirable characteristics for ornamental purposes. The polystyrene trays with higher volume cells (100 mL) contributed to the higher quality of ornamental pepper seedlings.

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.

Daylily (Hemerocallis) is a perennial herbaceous plant widely used in landscape gardening. Daylilies are prized for their long term flowering mainly in late summer and low maintenance cultivation. According to flower spike height, the varieties are divided into runt, medium-growing and tall. The article contains the results of the study of 21 medium-growing daylily varieties’ terms of flowering in the botanic garden of the Volga region State University of Technology (Yoshkar-Ola, the Republic of Mari El). The research was conducted in 2015 - 2017. The calendar dates were converted into a continuous series. All varieties were classified as early, medium or late according to the terms of the beginning and the end of flowering and its duration. During three years of research, the earliest beginning of the phenological phase was registered in 2016, and the latest one  - in 2017. The early beginning and ending of flowering were typical for the varieties “Dr Regel” and “Royal Sovereign”. The late beginning of flowering was registered for the “Country Club” variety, and the late ending - for “Sandalwood”. Other varieties were classified as medium-term. The varieties “Royal Sovereign”, “Tejas”, and “Sugar Candy” are characterized by a short flowering period, while “Sandalwood” and “Derby Bound” - with a long one. It was established that the late-flowering varieties are characterized with a longer flowering period.

Abstract The study was conducted in one of the private orchards in the Saqlawiya area - Fallujah during the 2020 growing season. The foliar spray was used to study the effect of the timing of foliar spraying (three sprays, the first at the beginning of flowering, second at the stage of full flowers blooming, and the third at the stage of petal fall), Presented with symbols (D1, D2 and D3), respectively. The second factor consisted of spraying with boron and zinc with the following concentrations (0,1, and 3 gm. L-1), mentioned as (S0, S1, S2, S3), respectively. these elements were used singly or in the form of a mixture with the same concentrations. This study aims to study the effect of the two factors on the growth and setting of apple trees, cv. Ibrahimi. Therefore, (36) five-year-old apple trees with homogeneous vegetative growth were selected as much as possible. The results revealed that foliar application with boron and zinc for the Ibrahimi apple trees improved the quality of the fruits and their vegetative and flowering traits. The results revealed that spraying with micronutrients at the stage of petal fall had a significant effect on flower traits and yield especially the media culture (M3) which presented the best results for the traits. The results revealed that spraying with micronutrients at the stage of petal fall had a significant effect on flower traits and yield especially the time (D3) which presented the best results for the traits (leaf area, Rate of increase in the length of the branches, Rate of increase in branch diameters, Fruits set Percentage, Percentage of fallen fruits and Percentage of remaining fruits, which reached (24.25cm2, 56.77cm, 0.42cm, 26.65%, 45.25%, 54.75%), respectively. On the other hand, spraying with micronutrients achieved significant effect, especially (S3), that gave the highest values for the traits (Rate of increase in branch diameters, Fruits set Percentage, Percentage of fallen fruits and Percentage of remaining fruits), which were (37.50 cm, 0.42%, 26.65%, and 46.71 gm L-1).

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.

 The aim of this work was to verify the efficiency of the anticipated selection of superior plants in intrapopulation breeding of passion fruit. The experiment was conducted at the Mato Grosso State University experimental area. Eight populations were evaluated. Planting was carried out in August 2010 following the randomized blocks experimental design, with ten repeats and ten plants per plot. The production characteristics of mass and number of fruits were evaluated from data obtained from two cultivation periods, the first year and the full two-year cycle of culture. Estimates of genetic parameters indicate the possibility of selection gains. The accuracies of fruit production, fruit number and fruit mass characteristics had high magnitude, independent of the selection cycle. Coincidence index estimates were high for all characteristics. Based on the results, early selection (first year) was efficient and reduced the time of selection for the best plants and can be used for passion fruit breeding.
