The objective of this study was to test container of polyethylene bags and protected environments on the papaya seedlings production, from May to August of 2008, in Aquidauana state of Mato Grosso do Sul (MS), Brazil. Five bags of polyethylene were used: 7.5 cm x 11.5 cm, 205.9 cm³; 8.4 cm x 10.6 cm, 238.1cm³; 10.0 cm x 16.5 cm, 525.2 cm³; 12.0 cm x 12.0 cm, 550.0 cm³ and 15.0 cm x 21.5 cm, 1539.8 cm³. These containers were placed in three protected environments: greenhouse; screened nursery with Sombrite® and screened nursery with Aluminet®. Because there is no replication of growing environment, each one was considered an experiment. For each cultivation environment, it was adopted a completely randomized design with eight replications of two plants each. Initially, data were submitted to analysis of individual variance of the container (for each cultivation environment), then performing the evaluation of the residual mean squares and the combined analysis of these environments for comparison of protected environments. The greenhouse and nursery with thermal reflector screen produced the best seedlings. The bags of 15.0 x 21.5 cm produced the best papaya seedlings. The Dickson Quality Index pointed the nursery with screen of thermal reflector as the environment that produced the most vigorous seedlings, when using the best container.

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.

ABSTRACTThe objective of this study was to test the hypothesis that biochar, applied with cattle manure, promotes better development of seedlings of Magonia pubescens St. Hil. The experiment was conducted at the State University of Mato Grosso, Nova Xavantina, Brazil, in 2011. We used a completely randomized design, with twelve treatments and three replications. The substrates formed by the higher levels of cattle manure plus biochar (30%) provided better results of height, diameter and aerial biomass. However, the Dickson Quality Index has not confirmed the quality of seedlings in these treatments. We also observed that the doses of biochar (20 and 30%) when added separately to the Latosol, are not efficient for the growth improvement of the seedlings. Based on the present results, we validate the hypothesis that substrates formed with a mixture of cattle manure and biochar are effective to improve the production of seedlings of M. pubescens.

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.

ABSTRACT: This study sought to evaluate the number of bruises on bovine carcasses and their relationship with loading rates in different truck models. Bruising percentages in the hindquarter, forequarter and short rib regions were evaluated. The space occupied on the truck by each animal in m² was defined as the Practiced area, obtained by dividing the body area by the number of males and females transported in straight trucks (10.60 x 2.40 m) and livestock trailers (14.80 x 2.60 m), 240 and 168, and 120 and 93, respectively, and 80 males in a straight truck with trailer configuration (17.50 x 2.60 m). The minimum area occupied by the animals was assessed according to the Farm Animal Welfare Council (FAWC) and Animal Welfare Advisory Committee (AWAC). The data was analyzed in a completely randomized design and included two sex classes, three carcass regions and three truck types. For males, the minimum areas (m²) calculated by the FAWC and AWAC were smaller (1.37 and 1.29 m², respectively) for the straight truck. The straight truck with trailer configuration had the lowest (P=0.0025) bruising index in the forequarter region (15.1%) and the highest (P=0.047) in the short rib region (30.5%). Females transported in the livestock trailer had a higher (P<0.001) percentage of bruises in the forequarter region (51.7%). There was a relationship between the high bruising rates and the loading rate Practiced for the males. Estimations made by the AWAC are close to those practiced in the upper Pantanal region of Mato Grosso do Sul, Brazil.

Dipteryx Alata

The study aimed to evaluate the influence of reflective materials on the cultivation bench and the use of rice husks over the substrate in the formation of Dipteryxalata seedlings. The experiment was carried out in the experimental area of the Mato Grosso do Sul State University, in Cassilândia-MS, from November 1st, 2016 to January 26th, 2017. A completely randomized design in a 5 x 2 factorial scheme was used, with five replications and five plants per plot. Four reflective material for the cultivation bench and treatment without reflective material (control), combined with or without rice husks over the substrate (0.5 cm layer), were evaluated. Laminated paper tray, mirror, reflective fabric (known as “fake sequin fabric”), and aluminum foil were used as reflective materials. The reflecting materials did not differ in the reflectance of photosynthetically active radiation. However, the mirror and the aluminum foil reflected more than the control. The use of rice husk over the substrate did not increase the Dipteryxalata seedlings' quality. The mirror as a reflective material produced Dipteryxalata seedlings of higher quality than the system without material reflector called control.

The choice of a substrate that meets the nutritional and physical demands of papaya seedlings with the use of organic wastes is directly linked to increases in crop yield and is an important environmental and economic alternative. Aiming to produce good-quality papaya seedlings while considering the composition and availability of substrates, this study examined the influence of applying increasing rates of poultry litter biochar as a substrate component in the production of papaya seedlings. The study was developed in a protected environment belonging to the Federal University of Campina Grande (UFCG). The experiment was laid out in a completely randomized design with a 6 × 2 factorial arrangement consisting of six rates of biochar (4, 8, 12, 16 and 20 t ha-1 and the control) and two papaya cultivars (Formosa and Ouro), with four replicates. Plant height, stem diameter, number of leaves and leaf area were evaluated 90 days after sowing. The fresh and dry biomass of shoots and root system and the Dickson Quality Index were also evaluated. In conclusion, the rates that provided good development of papaya seedlings were 8 and 16 t ha-1, and papaya cultivar Ouro showed better growth results.

ABSTRACTThis study aimed to determine the effects of the luminosity and type of container on producing Cassia grandis seedlings. Thus, in a substrate composed by topsoil + wood powder (1:1) the seedlings were grown into plastic tubets containing 0.3 dm3 of such substrate, or into plastic pots containing 1.0 dm3 of the same substrate, and subjected to 50 and 25% shading or full sunlight. The assessments were performed every two weeks by measuring plant height and stem diameter, during eight weeks period. At the end of this period, the leaf area, dry mass of shoots and roots, the ratio between height of plant/diameter of stem, and the Dickson quality index were also assessed. The experiment was carried out in a completely randomized design with treatments arranged in a 3 x 2 factorial [3 luminosity levels (50, 25% shading and full sunlight) x 2 types of containers (plastic tubets and clay pots)] with four replicates of 10 seedlings each. Means were compared by Tukey test at 0.05 probability level and adjustments for the non-linear regression polynomial curves for the assessed characteristics were computed in function of time. Shadings of 25 and 50% were the best alternatives to luminosity; and the tubets were the most suitable containers for production of Cassia grandis seedlings.
