The success of seedling production for ornamental or any other crops depends on several factors, including the use of highquality seeds and the choice of suitable substrates. The aim of this work was to evaluate the use of different organic residues as substrates and sowing depths on the emergence and initial development of pansy seedlings. Two lots of pansy seeds were used. Seed lot quality was evaluated for water content determination, 1000-seeds weight, germination, first count of germination, accelerated aging, seedling emergence in sand. Post emergence was evaluated by the emergence speed index, shoot length, shoot dry matter and number of leaves. The experiment was performed under completely randomized design, with four replicates. Data were submitted to analysis of variance through the F-test and the means, compared to each other by the Tukey test, at 5% probability. The most indicated sowing depths for the development of pansy seedlings were 1.5 and 2 cm while the substrate which presented the best results was the Beifort® S10.

Papaya is a tropical fruit of great importance in the international and national market. For crop success, the use of quality seedlings is of paramount importance and substrates formulated from organic sources may be a viable alternative. In this context, the objective of this study was to evaluate the initial development of papaya seedlings in different formulations and levels of organic substrates. A completely randomized design was used in a 4x4+1 factorial scheme, corresponding to four substrate formulations, containing decomposed buriti stem (CDB). The treatments included of the following: (CDB, ½ CDB + ½ poultry manure, ½ CDB + ½ cattle manure and ½ CDB + ½ gray with plant origin sourced from materials resulting from the burning of plant material (stem, branches); four proportion levels of the formulations of the substrates mixed to the soil (25; 50; 75 and 100%) and the additional control (100% soil). The following variables were measured: plant height, leaf area, number of leaves, shoot dry matter, root length and root dry matter at 42 days of seedling cultivation. The results showed that use of an ideal source of organic matter is feasible in the production of papaya seedlings. The substrate consisting of CBD + poultry manure had great potential to be used in the production of papaya seedlings.

Dipteryx Alata

O objetivo do trabalho foi avaliar o desenvolvimento de mudas de baruzeiro (Dipteryx alata Vog) em função de proporções de gesso (0%; 1,6%; 3,2%; 4,8% e 6,4%) com base em volume e adubação com cinza de madeira (ausência e presença) misturadas ao substrato Bioplant®. Constituiu-se assim um esquema fatorial 5x2, em delineamento inteiramente ao acaso, com três repetições e quatro plantas por parcela. O experimento foi conduzido de janeiro a março de 2009, em viveiro com cobertura e laterais de sombrite preto (50% da luminosidade natural), situado na Fazenda Japão, município de Orizona, Goiás. Como recipiente foram utilizados sacos de polietileno de 15 x 25 cm, onde colocou-se uma sementes por recipiente, ficando a extremidade superior da semente cerca de 2,0 cm de profundidade. As irrigações foram realizadas diariamente, no período da tarde. Aos 152 dias após a semeadura, avaliou-se altura de muda (AM), diâmetro de caule (DC), número de folha (NF), número de folíolos por folha (NFF), número de folíolos por planta (NFP), comprimento da raiz principal (CR), massa da matéria seca das raízes (MSR), massa seca da parte aérea (MSPA), massa seca total (MSTO) e índice de qualidade de Dickson (IQD). O gesso agrícola proporcionou melhor desenvolvimento inicial das mudas de baruzeiro, no entanto sua associação com cinzas de madeira, juntamente com o substrato, não favoreceu o desenvolvimento das mudas.Addition of agricultural plaster and wood ash to substrate in baruzeiro (Dipteryx alata Vog) seedlings developingAbstract: This study aimed to evaluate the baruzeiro seedlings development in function of plaster proportions (0%, 1.6%, 3.2%, 4.8% and 6.4 %) based on volume and fertilization with wood ash (absence and presence) added to the substrate Bioplant ®. It constitutes therefore a 5x2 factorial arrangement, in a completely randomized design with three replications and four plants per plot. The experiment was conducted from January to March 2009, in coverage nursery and side with shade screen (50% of natural light), located in Fazenda Japão, Orizona county, Goiás. As container was used polythene bags of 15 x 25 cm, which was placed one seeds per container, with the upper end of the seed approximately 2.0 cm depth. The irrigation was performed daily in the afternoon. At 152 days after sowing, was evaluated seedling height (SH), stem diameter (SD), sheet number (SN), number of leaflets per leaf (NLL), number of leaves per plant (NLP), length the main root (LR), dry mass of roots (DMR), dry mass of aerea part (DMAP), total dry matter (TDM) and Dickson quality index (DQI). The plaster provided better initial development of seedlings baruzeiro, however its association with wood ashes, along with the substrate, didn't favor the growth of seedlings.

Yellow Passion Fruit

This study aimed to evaluate different substrates to produce yellow passion fruit seedlings. For this purpose, an experiment was carried out in a greenhouse, from April to June 2016. A completely randomized design with five replications, in a 6 x 5 factorial scheme was used. The first factor was the alternative substrates (poultry, cattle and equine manure, sugarcane and coconut bagasse, and Organomais compost). The second factor was the replacement levels to the commercial substrate of Plantmax® (100:0, 75:25, 50:50, 25:75, 0:100). The seedling evaluation was carried out 42 days after sowing. The following variables were analyzed: length, width, and the number of leaves; plant height and shoot dry matter. A significant effect (P0.05) for the interaction between the factors was verified. The addition of 60% cattle manure and Organomais to the commercial substrate Plantmax® promoted greater length, width, and the number of leaves, plant height, and shoot dry matter accumulation in the yellow passion fruit seedlings.

ABSTRACT: This study aimed at evaluating the effects of different desiccation periods of Urochloa decumbens on the initial development of Eucalyptus urograndis (clone C-219H). The experiment was conducted in 100 liter concrete boxes, previously filled with Dark-Red Latosol. U. decumbens was sown in all plots, except for the control sample without covering. After 95 days from sowing, the herbicide glyphosate (dose of 1,424 g a.e. ha-1) was sprayed at intervals of 0 (Apply-Plant), 7, 14, 21, 28 and 35 days before eucalyptus planting, plus a control sample without covering, totaling seven treatments. A completely randomized design with six replications was used. Eucalyptus plants were evaluated 30, 60 and 90 days after planting (DAP), when the height of the plants and the diameter of the stem were determined. At the end of the experimental period (90 DAP), the leaf area and the dry matter of leaves and stem were measured. It is possible to conclude that the Apply-Plant modality was harmful to some of the eucalyptus characteristics (E. urograndis - C-219H), while planting the seedlings in periods over 14 days after the desiccation of U. decumbens plants promoted a better development of the culture.

ABSTRACT This assay was conducted in the experimental area of the Federal Institute of Bahia, Campus Guanambi, BA, and aimed to evaluate agronomic traits of Prata, Cavendish, Gros Michel and Maçã banana cultivars three production cycles. The 72 treatments, 24 cultivars and three production cycles were arranged in a split plot scheme in time, in a completely randomized design with five replications and four plants per plot. Plots were arranged in 24 cultivars, Prata-Anã, Maravilha, FHIA-18, FHIA-18 BRS, BRS Platina, JV42-135, Pacovan, Japira, PV79-34, Pacovan-Ken, Preciosa, Guarantida, Maçã, Caipira, BRS Tropical, BRS Princesa, YB42-03, YB42-07, YB42-47, Grande-Naine, Calypso, Buccaneiro, FHIA-23 and FHIA-17; and subplots consisted of three production cycles. Data obtained were submitted to analysis of variance. The average of the cultivars were grouped by Scott-Knott criterion (p<0.05) and production cycles compared by Tukey test (p<0.05). ‘JV42-235’, ‘Japira’ and ‘Pacovan-Ken’ cultivars had larger size and ‘Grande Naine’ had smaller size. ‘Prata-Anã’ cultivar had higher number of leaves at harvest, with leaf area index similar to the others. ‘BRS Platina’ cultivar is earlier at flowering and harvest. ‘Maravilha’, ‘BRS Platina’, ‘FHIA-23’, ‘BRS Tropical and BRS Princesa’ cultivars presented greater potential for use by farmers.

ABSTRACT: The objective of this study was to evaluate the initial competitive ability of canola hybrids against Brassicaceae and Poaceae species in terms of root and shoot resources. Two experiments were conducted in greenhouse, in a completely randomized design with four replications. The treatments consisted of interference conditions by root + shoot interference (root+shoot) and shoot interference (Light); and Brassicaceae and Poaceae weeds competing with hybrid of canola (Hyola 61 and Diamond) with different traits for competitiveness. The plant height, root length, dry matter of shoot and root, number of leaves and leaf area were evaluated. Data were compared using orthogonal contrasts. The turnip and volunteer canola reduced root development of the Hyola 61 in root + shoot interference, and among the Brassicaceas weeds, turnip caused greater losses. Brassicaceas weeds caused largest reductions in Diamond’s hybrid growth compared to Poaceae, mainly under light interference. Brassicaceas and Poaceae weeds cause similar damage to Hyola 61 hybrid, and the injury is higher for root +shoot interference. The black oat induce shoot growth in the Diamond hybrid under shoot interference, while among the Brassicaceae weed species, there were no differences.

Abstract: The aim of this study was to evaluate the effect of industrial seed treatments on the physiological potential of soybean seeds over storage. Four mixtures of agrochemical products in association with two fertilizers were tested. The agrochemical product mixtures were carbendazim/thiram + imidacloprid/thiodicarb; pyraclostrobin, thiophanate-methyl, and fipronil; thiophanate-methyl/fluazinam + bifenthrin/imidacloprid; and metalaxyl-m/fludioxonil + thiamethoxam. The two fertilizers were 7% N, 16% P2O5, 0.6% Co, and 2.5% Mo; and 1% Co, 10% Mo, and 7% P2 O5. The experiment was carried out in a completely randomized design in a split-plot arrangement in time, with four replications. The treatments were allocated in the plots, while the storage periods (0, 30, 60, 90, and 120 days) constituted the split-plots. The following tests were carried out in each period: first count of germination, germination, accelerated aging, emergence speed index in sand substrate, and final seedling emergence in sand substrate. Seed germination and vigor declined over the storage period, especially after industrial treatment. Pesticide mixtures of a carbendazim/thiram fungicide base and an imidacloprid/thiodicarb insecticide base most impaired seed physiological potential throughout storage, regardless of fertilizer use in the industrial treatment.

Abstract:Niger is a promising oilseed species for biodiesel production but there is no much information about the physiological potential of its seeds. Thus, the aim was to adapt the methodologies of accelerated aging test on six lots of niger seeds. The test was carried out by traditional and with saturated salt solution (20 and 40 g NaCl.100 mL-1) methods at 41 and 45 °C for 24, 48, 72 and 96 hours. After the decay period, the seeds were submitted to the germination test, proceeding to an evaluation on the seventh day after sowing, counting the normal seedlings percentage. A completely randomized design with four replications of 50 seeds was used and the means were compared by Tukey's test. The accelerated aging test was correlated with seedling emergence and provided lots classification in at least two levels of vigor. For the accelerated aging test, the method with 20 g NaCl.100 mL-1 at 41 °C for 24 hours is recommend. The traditional method is not suitable because it provides water content variation between samples above what is tolerable.

The objective of this study was to evaluate the physiological and sanitary quality of seeds of rocket; the research was done at the Laboratory of Seed Analysis and greenhouse of the Department of Plant Science, Federal University of Pelotas (UFPel). Four lots of the cultivar "Antonella'' were tested for following features: initial and final moisture content, germination rate, first count of germination, accelerated aging with saline solution, dry matter contents, seedling shoot and root length, emergence speed index, emergence of seedlings in substrate, electrical conductivity and sanitary condition. A completely randomized design with four replications was used for all tests done and means were compared by Tukey test (P≤0.05). For all tests performed it was concluded that despite changes in the ranking of the best lots, there was agreement regarding the indication of the inferiority of the lot 3 in all tests and it was also observed that the incidence of fungi associated with seeds of rocket interfere with the physiological quality of the lots.
