Formação de mudas de alface em bandejas preenchidas com diferentes substratos

This study was conducted in the Department of Horticulture and Experimentation at the University Jose do Rosario Vellano (UNIFENAS) in Alfenas-MG, Brasil in order to evaluate the formation of lettuce seedlings in trays filled with different substrates. The materials used to compose the substrates were pig bed base with wood shavings (M), pig bed with base coffee straw (C), earthworm humus (H) and commercial substrates Nutriorg (R) and Plantmax (R) The use of these pure substrates and various mixtures permitted the formation of 18 substrates that constituted the treatments. The experimental design was a completely randomized design with three replications. The lettuce seedlings were formed with the lettuce cultivar Regina. The seeds were sown in trays with 128 cells filled with the substrates under study. Each experimental unit was compost of 64 cells. The conduct of the experiment was within a protective structure of 85 m 2, model chapel with transparent plastic cover 100 microns thickness, additives against ultraviolet rays. After 30 days of sowing, ten seedlings were harvested randomly within each experimental unit for evaluating the number of leaves and the plant height. It was also evaluated the fresh and dry mass of aerial part and fresh and dry mass of root. It was concluded that the substrate T1 - M met the best features for the formation of lettuce seedlings in trays of 128 cells.

Cobertura e depósito de calda fitossanitária em plantas de café pulverizadas com equipamento original e adaptado para plantas altas

The objective of this study was to evaluate the coverage of spray droplets on coffee plants as well as their deposition using a sprayer with and without adaptation of an auxiliary branch for tall plants. The experiment was conducted following a randomized block design with six treatments and four replications to evaluate the percentage of coverage for the spraying liquids in water sensitive paper fixed at four quadrants and two heights (lower and upper) of the plants, and the spray deposit with metallic marker (MnSO4) on sheets in the same positions of the water sensitive paper in two spray volumes (450 and 750 L h(-1)). The experiment was conducted in October 2011 in the town of Patroc nio-MG, and the experimental plots consisted of 30 plants of Catua IAC-99, with approximately 12 years of age and average height of 3.50 meters. The experiments were conducted following a randomized block design with six treatments and four replications to evaluate the coverage and deposition, in two spray volumes (450 and 750 L ha(-1)). Leaves were collected in four positions and also at the top four in the lower canopy. The results of the evaluations were analysed statistically by F test and for comparison of means by Tukey test at 5% probability. The auxiliary branch installed at the rear of the equipment is the most suitable when compared to use of equipment without this feature or installed in the front of the equipment. Furthermore, the application volume of 450 L ha(-1) results in coverages and deposits of spraying liquids equivalents to volume of 750 L ha(-1), considered sufficient according to the parameters evaluated.

Determinação de complexos de urânio em solo usando a técnica de difusão em filmes finos por gradiente de concentração (DGT)

This paper proposes to assess the lability of complexes of uranium in soil using the technique of Diffusion in Thin Films by concentration gradients (DGT) in the vicinity the Osamu Utsumi mine, located in the municipality of Caldas - MG. The technique is based on the 1ª Fick Law, where metal complexes diffuse through a gel, which in turn is adsorbed on a resin. The metals adsorbed are recovered by an analytical technique and quantified by optical emission spectrometer with plasma inductively coupled (ICP-OES) or mass spectrometry with inductively coupled plasma (ICP-MS)
