A produtividade florestal depende das potencialidades genéticas das matrizes, do ambiente proposto pelos substratos, frequência de irrigação, disponibilidade de luz, nutrição e das condições fitossanitárias. Assim, objetivou-se com o presente estudo analisar os efeitos da aplicação de potássio e de irrigação na qualidade de mudas de Eucalyptus urophylla. Para tal adotou-se o delineamento experimental em parcelas subdivididas definindo as 2 lâminas de irrigação (10 mm e 15 mm) como parcelas e os 5 níveis de potássio (0; 1,2; 2,4; 4,8; e 9,6 g L-1) como subparcelas, em 5 repetições compostas por 9 plantas. A comparação entre os métodos foi feita através teste de Tukey com 5% de probabilidade. Aos 120 dias, foram avaliadas: altura da parte aérea, diâmetro do colo, massa seca da parte aérea e da raiz. O tratamento testemunha apresentou as melhores médias em todos os parâmetros, sendo considerado o mais eficiente. A lâmina de irrigação de 15 mm foi considerada a mais eficiente. Portanto, conclui-se que qualquer que seja o incremento de potássio na produção de mudas, o mesmo deve se relacionar harmonicamente com a quantidade pré-existente no substrato base e com as exigências da cultura, de maneira que haja equilíbrio entre todas as partes. Palavras-chave: manejo hídrico; rustificação; substrato; casa de sombra.   IRRIGATION AND POTASSIUM LEVELS IN THE QUALITY OF EUCALYPTUS   ABSTRACT:  Forest productivity depends on the genetic potential of the matrices, the environment proposed by the substrates, frequency of irrigation, availability of light, nutrition and phytosanitary conditions. Thus, the aim of this study was to analyze the effects of potassium and irrigation on the quality of Eucalyptus urophylla seedlings. For this purpose, the experimental design was adopted in subdivided plots, defining the 2 layers of irrigation (10 mm and 15 mm) as plots and the 5 levels of potassium (0; 1.2; 2.4; 4.8; and 9.6 g L-1) as subplots, in 5 repetitions composed of 8 plants. The comparison between the methods was made using the Tukey test with a 5% probability. At 120 days, the following were evaluated: height of the aerial part, diameter of the neck, dry mass of the aerial part and the root. The control treatment showed the best averages in all parameters, being considered the most efficient. The 15 mm irrigation blade was considered the most efficient. Therefore, it is concluded that whatever the potassium increase in the production of seedlings, it must be harmoniously related to the pre-existing quantity in the base substrate and to the requirements of the culture, so that there is balance between all parts.

Beans are one of the most used foods to meet the energy needs of the Brazilian diet, requiring farmers to use high seed physiological potential. The aim was to evaluate the physiological quality of beans stored for 360 days. Analyses were performed at 0, 30, 90, 180, 270, and 360 days after receiving the seeds (S1 and S2) and grains (G1 and G2) of BRS Splendor. Tests of germination, accelerated aging, cold, speed of germination, average length of shoots, and root were performed. The experimental design was completely randomized split-plot in time and the means were compared through Tukey test at 5% probability. Seed germination was not affected in S2, while the drop in S1 and G1 was significant. The vigor of grains from field 1 declined from 91 to 50% and from 93% to 76% by accelerated aging and cold, respectively, after 360 days. The germination speed tests performed showed a decreased during the experiment. The grains from field 1 had lower physiological quality. The accelerated aging and cold tests, through the speed of germination parameter, showed decrease in the vigor of the Splendor BRS. The storage period influenced the physiological quality of the beans tested.

ABSTRACT The quality of seeds of forage species can be influenced by the different harvesting methods used. The aim of this study was to evaluate the physical and physiological quality of seeds of Panicum maximum, cultivars ‘Massai’ and ‘Mombaça’, obtained by the methods of ground sweeping and direct heading (cutting of the panicles) of different farmers in the year 2014. The test consisted of three lots of each cultivar from seed farmers in the state of Goiás, Brazil. The experimental design was completely randomized, in 3 x 2 factorial scheme (farmer x harvesting methods) with four replicates. The following variables were analyzed: physical purity, 1000-seed weight; germination and first count of germination. At the end of the germination the percentage of dormancy and dead seeds were evaluated by the tetrazolium test of the remaining seeds, in addition to the abnormal seedlings. The data were submitted to analysis of variance and the means of the treatments were compared by Tukey test at 0.05 probability level. Seeds of P. maximum ‘Massai’ and ‘Mombaça’ collected by ground sweeping have superior physiological quality despite the low level of purity of the lots, compared to direct heading method.

Abstract In the implantation of forests, soil tillage can affect the soil fauna, but over the years, it is possible that forest development can recompose the biological indicators of soil quality. So, the aim of this study was to evaluate the influence of different periods of eucalyptus development on community of edaphic fauna. The experiment was carried out in forest areas in the municipality of Ametista do Sul, RS. The Experimental design was completely randomized with 6 treatments, once 4 of the treatments were with different ages of the Eucalyptus grandis (two, four, six and eight years after trasnplant – YAT); plus 2 control treatments: Native Forest and Soil Naked, with 7 collection points. To sample the edaphic fauna, it was used traps such as PROVID. Also, the edaphic fauna was sampled at the depth of 0-5 cm for the quantification of mites. It was carried out the counting of individuals at the level of order and family for the mites, the means of the groups were submitted to the Tukey test and comparisons by Orthogonal Contrasts and calculated indices of Biodiversity: Margalef Richness, Simpson dominance, Shannon diversity and Pielou uniformity. The results showed lower abundance of individuals in Naked soil, while the Native Forest presented the best Biodiversity indices. With eight years of implantation of eucalyptus there was recovered the biological quality of the soil expressed by the population of springtails. The population of oribatídeos mites increased expressively from the six years of implantation of eucalyptus.

Objective: To compare the effect of earthworm humus (vermicompost) withrespect to that of a standard fertilization treatment with conventional chemicals onthe yield and fruit quality in the cultivation of habanero pepper (Capsicumchinense).Design / methodology / approach: The experimental design was of randomizedblocks with seven replicates. The treatments consisted of 100% worm humus, 50%worm humus + 50% soil combination, as well as soil with chemical fertilizers as acontrol. The number of fruits, the quality of the fruits (length, diameter, and weight)of three cuts (harvests), in addition to the yield per plant, were evaluated. The datawere analyzed with an analysis of variance and when statistical differences weredetected, a means comparison was performed with the Tukey test (P&gt;0.05). 2Results: The 100% vermicompost treatment did not significantly reduce the heightand diameter of the plant stem. Regard yield, a 15% increase was observed,although it was not significant compared to the control. Likewise, the quality of thefruits did not decrease.Study limitations / implications: The combination of 50% vermicompost and soilor less could affect the development and yield of habanero pepper crops.Findings / conclusions: Supplying earthworm humus does not affect the yield orquality of habanero pepper fruits, which is an alternative for nutrients supply at lowcost which is also an environmentally friendly practice.
