This work was carried out at the Mato Grosso State University, Tangará da Serra campus, Brazil, aiming to evaluate the agronomic characteristics of crisphead lettuce cultivars depending on filter cake rates application in protected environment. We used a randomized blocks design in a 3x4 factorial scheme, composed by three cultivars (Júlia, Tainá and Rafaela) and four rates (0, 10, 20 and 40 t ha-1), with four replications. Plots size was 1.2x1.2 m with 16 plants spaced 30x30 cm each, among which the 4 central plants were evaluated. We assessed the total fresh mass, marketable fresh mass, head fresh mass, total leaf number, marketable leaf number, stem length, stem diameter and plant diameter. The cultivar Rafaela presented the highest performance for fresh mass total, marketable and head, at the filter cake rate of 20 t ha-1. The cultivars Júlia and Rafaela had greater plant diameter, stem diameter, total leaf number and marketable leaf number than cultivar Tainá, regardless the filter cake rate applied. The filter cake application provided higher yield and marketable quality for crisphead lettuce.

The ipecac (Psychotria ipecacuanha), Rubiaceae, is an important medicinal plant, native to America with the largest area of occurrence in the state of Mato Grosso, Brazil, mainly in the city of Caceres. The aim of this study was to assess the effect of substrates, position of root cuttings and types of cuttings on ipecac propagation. In the first experiment were used cuttings with 2 cm in length to root, in the experimental design of randomized blocks in split-plot 2 × 2 with two positions (vertical and horizontal) and two substrates (sand and phenolic foam) with 15 replications and 15 cuttings in each. In the second experiment we introduced basal and apical cuttings of the root and shoot in sand, commercial substrate for vegetables, soil of the natural environment and phenolic foam. The experimental design was of randomized blocks in factorial scheme 4 × 4 with four replications and five cuttings. The analyzed variables were diameter, length, number of shoots and number of leaves per shoot. Seedlings of ipecac can be obtained by root cuttings, 2 cm in length, placed horizontally or shoot cuttings with two buds placed vertically. The best substrates were sand and soil of the natural environment of the species.

In order to study the behavior of three lettuce cultivars (Júlia, Tainá e Grandes Lagos) in four doses of filter cake (0; 10; 20 and 40 ton ha -1), in greenhouses (tunnel) was conducted an experiment at the Universidade do Estado de Mato Grosso, an area with Oxisol (clay) in the months from March to May 2009. The experimental design was randomized blocks arranged in a 3x4 factorial (cultivars x dose) with four replications. We evaluated the following agronomic characteristics: circumference of the plant (CP), total fresh mass (TFM), fresh commercial mass (FCoM), head fresh weight (HFW), stem diameter (SD), number of marketable leaves (NML), stem length (SL) and total number of leaves (TNL). The cultivars Júlia and Tainá responded to fertilization with filter cake until the dose of 40 ton -1. The cultivar Grandes Lagos responded to fertilization with filter cake until the dose of 35 t ha -1 for TFM and HFW and up to 40 ton ha -1 for FCoM. The cultivar Grandes Lagos had the best performance in TFM, FCoM, CP and SL compared to others cultivars, and equated with the cultivar Tainá in HFW and NML and with the cultivar Julia in SD. All cultivars had similar behavior in TNL. The organic fertilization with filter cake increases the productivity of cultivars of lettuce.

The mama-cadela (Brosimum gaudichaudii Trécul) is a species of the Brazilian cerrado considered a priority for conservation and management of plant genetic resources. The roots of B. gaudichaudii are used to obtain psoralen and bergapten to produce medicine against vitiligo. The objective of this study was to evaluate the effect of seed size and levels of shading in the early development of seedlings of B. gaudichaudii. It was used a completely randomized experimental design in factorial scheme 3 x 3, three seed sizes (small, medium and large) and three shade conditions (0%, 30% and 60%), with four replications of 25 seeds. These characteristics were percentage of emergence and survival, height, basal diameter, height/diameter and number of leaves of seedlings until 120 days after sowing. The highest percentage emergence occurred in 60% shading and large seeds (70%). These seeds originate seedlings with higher height (20.4 cm) and smaller basal diameter (1.4 cm), while small seeds at the same level of shading formed smaller height (8 cm) and basal diameter (2 4 cm) of seedlings. The number of leaves was higher in cultivated plants in full sun and was not influenced by the size of the seed. The height/diameter was lower for seedlings grown in full sun. The highest quality of seedlings of B. gaudichaudii is obtained with large seeds provided no shading.

The production of the Japanese cucumber Tsuyataro was evaluated using methods of stems growth conduction, controlling the lateral buds and number of stems per plant, through pruning. The research was carried out from October to December 2010, in a protected environment in Tangará da Serra, Mato Grosso state, Brazil, using a randomized blocks design, with five replications, in a factorial scheme (2x3). The first factor was the pruning, i.e., removal or not of lateral stems and the second factor was constituted of the control of number of stems: one, two and three stems per plant, with five replications. We evaluated the following characteristics: total and marketable number of fruits, commercial fruits rate, fruit length, fruit diameter, fruit length/diameter ratio, total and marketable yield of fruit per plant and fruit average weight. The treatment with conduction of the main stem without removal of lateral buds had better performance on total and marketable number of fruits per plant (19.4 and 16.0) and higher total and marketable yield of fruits (4,235.8 and 3,438.3 g per plant). The pruning of lateral buds provided increase in length, diameter and average mass of cucumber fruits of 24.5 to 25.1 cm; 3.4 to 3.5 cm and 212.1 to 228.3 g per fruit, respectively.
