ABSTRACT The productivity and physicochemical quality evaluation is important, as it identifies superior populations. However, launching products requires following the descriptors according to DHE test instructions. Thus, this study aimed to evaluate three passion fruit populations with high productivity and physicochemical quality characteristics for commercial launch. The experiment was conducted at the State University of Mato Grosso experimental area, located in the municipality of Tangará da Serra, MT. The experimental design was complete randomized block design with four replicates and ten plants per plot. The physicochemical characteristics were submitted to analysis of variance and compared by the Tukey test. For the distinctiveness test, 25 descriptors were evaluated, where quantitative data have been converted into multicategoric data to obtain the dissimilarity matrix. From the dissimilarity matrix, groups were formed using the Tocher and UPGMA methods, Livestock and Supply Department. The highest productivity and number of fruits were verified for BRS Rubi Cerrado cultivar and UNEMAT S10 population. Populations and cultivars presented physicochemical characteristics that meet the required quality for both fresh consumption and industry use. Based on the distinction test among genotype, it was observed that the descriptors were effective for population differentiation. UNEMAT S10 population has characteristics that distinguish it from other cultivars and populations evaluated, and presents high agronomic performance; therefore, it can be launched as a commercial cultivar.

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 objective of this study was to evaluate the influence of rootstocks on passion fruit physicochemical characteristics. The experiment was conducted in two properties in Terra Nova do Norte municipality, Mato Grosso State, Brazil. The experiment was conducted in a 2×8 factorial, in a completely randomized block design with four repetitions, being two growing environments (Environment 1 and Environment 2) and seven rootstocks with one control. The rootstocks used were: CPAC M5-H-67, H-CPAC MJ-65, CPAC MJ-45-03, CPAC MJ-H-68, Passiflora nitida (PN), P. alata (PA) and P. edulis (PE), under the canopy of a yellow passion fruit, BRS Gigante Amarelo cultivar. The same cultivar without rootstock was used as a control. The fruits were randomly harvest from each block. The following physical, physicochemical and chemical analysis were performed: weight, fruit length and diameter of the fruit, skin thickness, total soluble solids content (TSS), total acidity (TA), TSS/TA and vitamin C content. The use of rootstocks and rootstocks x environment interaction influenced the passion fruit physical characteristics. The environments influenced fruit quality, except for total acidity content. Environment 1 resulted in best fruit quality. For the Environment 2 no weight and length variation caused by rootstocks was observed. All analyzed rootstocks produced fruit with suitable characteristics for ‘in natura’ consumption or industrialization.

ABSTRACT Co-inoculation consists of using microorganism combinations with synergic effect that surpass the results obtained with their use alone. The objective of this work was to evaluate the effect of inoculation and co-inoculation on soybean plants, and their residual effect on maize plants grown intercropped with ruzigrass (Urochloa ruziziensis), under different N fertilizer rates. The experiment was conducted at the experimental area of the Mato Grosso State University, Alta Floresta campus, in a Typic Hapludox. A randomized block design was used for the soybean crops; the treatments consisted of Bradyrhizobium japonicum inoculated single, or co-inoculated with Azospirillum brasilense, with 20 replications. A randomized block design in a strip-plot arrangement was used for the winter maize-ruzigrass intercrop (WMRI); the treatments consisted of combination of residual effect of inoculation and co-inoculation in the strips, and five N fertilizer rates (0, 50, 100, 150, and 200 kg ha-1) in plots with WMRI, with four replications. The co-inoculation of soybean seeds and its residual effect on the maize crops increased the root dry weight of plants of both crops; however, no increases were found for most vegetative and reproductive characteristics of maize plants. Yield and most characteristics evaluated had increasing linear responses to increases in N rates, indicating the plants could respond to rates above 200 kg ha-1.

Nitrogen fertilization is an essential practice for the increase in biomass of forage, reducing the seasonality of production throughout the year. Thus, the objective was to evaluate the green and dry matter accumulation of more sheaths leaf blades and stems of Brachiaria cultivars in the dry season. The experiment was conducted from May to October 2014, at the State University of Mato Grosso, Brazil, in an area of 1.500 m2. The experimental design was a randomized block design with three replications. The treatments were characterized by factorial 2 x 2 x 5, two forage (cv. Marandu and Mulato II), two N sources (urea and ammonium sulphate) and five doses of N (0, 50, 100, 150 and 200 kg ha-1). Nitrogen fertilization affected the productive characteristics of forages, with greater accumulation of biomass at a dose of 200 ha-1 kg N. The nitrogen sources and forage influenced to a greater magnitude green mass production and dry stalks.

Teak (Tectona grandis) is a high-value timber species in tropical regions. In Brazil, although teak has a high productivity, there are few studies related to its genetic improvement. This work aimed to estimate genetic parameters and evaluate potential gains of selection in a clonal test of teak installed in the state of Mato Grosso, Brazil. The experimente is in a randomized block design, with five replications, 3x3 m spacing, 22 treatments, and plots with six individuals. At five years, the genotypes were evaluated for survival (S), tree total height (H) and girth at breast height (GBH). There was significance and feasibility of selection for S and GBH. For H, the result was not significant, indicating few gains with the selection. The genetic parameters of clonal mean heritabilities and accuracy were of moderate magnitude for S and GBH and low for H. To best of our knowledge, this is the first work that estimates genetic parameters in a clonal teak test in the field in Brazil.

ABSTRACT: The passion fruit (Passiflora cincinnata Mast.) is a perennial and drought resistant species that represents a new alternative crop for small farmers in rainfed conditions. This study aimed to evaluate the vegetative and physiological development of passion fruit plants derived from two propagation methods and grown at varied planting spacing. The experiment was conducted from January to June of 2012, in the Universidade Estadual do Sudoeste da Bahia (State University from Southwestern Bahia), in Brazil. It was carried out in a randomized block design under a 2 x 3 factorial scheme, which consisted of two propagation methods (cutting and seeds) and three planting spacing distances within a row (1.5; 3.0 and 4.0 m), however, at same distance between rows (3.0 m), with four replicates and four plants per plot. Cuttings and seeds were sampled from adult plants pre-selected in native areas from Vitória da Conquista - BA, Brazil. Growth (stem diameter and leaf area) and physiological parameters (leaf chlorophyll content, leaf water potential before dawn, relative water content and leaf gas exchange) were assessed on the 90th, 120th and 150th day after transplanting of seedlings into the field (DAT). Based on our results, we concluded that despite plants propagated via cuttings showed most favorable water status, vegetative growth and photosynthetic capacity were lower whether compared to plants obtained from seeds.

Mangabeira (Hancornia speciosa Gomes), a fruit tree native to the Brazilian Cerrado, has great potential for commercial cultivation due to the quality of fruits, which can be consumed fresh or processed. However, it is necessary to expand research in the area of propagation of this fruit tree. The aim of this study was to evaluate different substrates and container volumes in the production of mangabeira seedlings, H. speciose, in Nova Xavantina-MT. The experiment was carried out at the nursery of the Mato Grosso State University (UNEMAT), Campus of Nova Xavantina in a randomized block design, in a 2 x 4 factorial scheme, with two container volumes (0.9 e 1.8 dm3) and four substrates (soil; soil + sand; soil + sand + bovine manure; and commercial substrate), totalizing eight treatments with four replicates and plots composed of 10 plants each. The greatest growth of mangabeira seedlings was observed using soil or soil + sand + bovine manure and 1.8 dm3 container.

ABSTRACT The present study aimed to describe histological traits of the graft welding process and evaluate the effect of rootstocks on the physical and chemical traits and the productivity of sour passion fruit populations. The experiment was arranged in a randomized block design, in a 4x2 + 4 factorial scheme (cultivars / canopy x rootstocks), three replicates and nine plants per plot. Commercial cultivars and populations and Passiflora alata and P. nitida rootstocks, in addition to ungrafted plants were used as canopy. Cleft grafting was the grafting type adopted. Traits analyzed such as productivity and physical and chemical quality of fruits were submitted to analysis of variance and compared by the Tukey test. The canopy morphology was evaluated according to descriptors of the Ministry of Agriculture, Livestock and Supply. Grafting was carried out for each graft/rootstock combination for histological analysis. Sections were obtained by freehand cuts, stained and mounted on semi-permanent slides, examined under optical microscope and photomicrographed. Rootstocks affected the early cultivation and reduced productivity and number of fruits of passion fruit populations. Grafting did not affect the quality of fruits or the canopy morphology. Considering the complete culture cycle, P. alata species is able to be used as rootstock. The anatomical study demonstrates the occurrence of better compatibility in the connection of P. edulis tissues on P. alata, compared to grafting on P. nitida.

ABSTRACT Nitrogen is essential for sustaining life on the planet, and it is the most important nutrient for obtaining high agricultural production. However, their use leads to the release of nitrous oxide with a global warming potential 296 times higher than the CO2 molecule, making it a challenge to reduce their use in agriculture. The objective of this research was to identify efficient popcorn inbred lines and responsive nitrogen use and exhibit a good expansion volume. For this, 29 inbred lines from the Germplasm Collection of Darcy Ribeiro North Fluminense State University (UENF) were evaluated at two contrasting levels of nitrogen availability (low and ideal) at two representative locations in the north and northwest of the state of Rio de Janeiro, Brazil, arranged in a randomized block design with three replicates. These inbred lines were discriminated against efficient use of nitrogen by multivariate GGE Biplot. Selective accuracy was close to 1, showing that the genotypes were enough to provide contrasting success in selection procedures. The first two main components (PC) retained 93.82% of the total variation, and PC1 furnished an information ratio (IR) that was unaffected by noise. L77 was the most unstable line, while P7, P2, P6, P3, P5, P4, P9, P10, P8, P9, L70, L74, and L55 were efficient and responsive. The GGE biplot method is recommended for the reliable identification of popcorn lines that are efficient and responsive to the use of nitrogen.

Hydrogen peroxide (H2O2) is a molecule that can flag plants under biotic and abiotic stress conditions. Among the kinds of stress, the salinity stress is the one that most usually affects plants. Consequently, the purpose hereof was to use hydrogen peroxide (H2O2) to mitigate the possible harmful effects of salinity in yellow passion fruit seedlings. We employed a randomized block design, in a 5 × 3 factorial scheme, corresponding to five irrigation water electric conductivity levels (0.3; 1.3; 2.3; 3.3; and 4.3 dS m-1) and three hydrogen peroxide concentrations (0; 5; and 15 μmol L-1), with four repetitions. The treatments were applied foliarly 7 and 15 days after the seedlings’ germination with hand sprayers. Sixty days after sowing, we evaluated the seedlings’ growth and quality variables, which finally proved that hydrogen peroxide mitigates the harmful effect of the irrigation water’s salinity up to 2 dS m-1 in the growth of yellow passion fruit seedlings at the concentration of 5 μmol/L. Nonetheless, excessive concentrations (15 μmol L-1) associated with high salt concentrations were proven detrimental to the seedlings’ phenological growth and quality.
