Research object. Populations of cervine animals (moose, red deer, roes) and their living environment in Mikieriai Forestry of the Public Institution Anykščiai Forest Enterprise. Research aim. To study the populations of cervine animals, their living environment and effect of these animals on forest in Mikieriai Forestry of the Public Institution Anykščiai Forest Enterprise. Research methods. Logic analysis of literature and systemic selective accounting. Research results. Cervine animals living in the forests of the Forestry are moose (density 7 pcs./1000 ha), red deer (12 pcs./1000 ha), roes (31 pcs./1000 ha). Because of their effect on forest planting and sprouts the number of cervine animals should be reduced as they browse, break stems and peel bark. The use of cervine animals is low. Before breeding fallow-deer in the forests of the Forest the basic breed should be moose, secondary – roe, minor secondary – red deer. When the fallow-deer are bred, to which the forests of the Forestry are good to live in and belong to the category of middle areas, the basic breed in the forests of the Forestry should be moose, secondary – roe and fallow-deer, minor secondary (undesirable) – red deer. From possible effect of cervine animals the forest planting and sprouts are protected by fences and repellents and protected area makes up 4,8 – 6,2% of the total area of the forests. Many recommended stimulants in biosphere range are also favourable for the increase of hunting fauna. The... [to full text]

O sistema de semeadura direta é caracterizado pelo mínimo revolvimento do solo e manutenção de resíduos vegetais em cobertura. Contudo, o descaso com o manejo do solo, tem proporcionado, sistematicamente, o surgimento de camadas compactadas em áreas agrícolas conduzidas nesse sistema, as quais podem ocasionar a diminuição da produtividade das culturas. Desse modo, o objetivo deste trabalho foi avaliar os parâmetros de máquina, solo e planta em função do cultivo de plantas de cobertura e quatro profundidades de atuação da haste sulcadora de adubo, em Latossolo compactado conduzido em sistema de semeadura direta. O experimento foi realizado em duas safras agrícolas (2013/2014 e 2014/2015) na área experimental da UTFPR, em um Latossolo Vermelho distroférrico, com textura muito argilosa (76% de argila). O experimento foi conduzido em delineamento de blocos ao acaso, sendo os tratamentos dispostos no esquema de faixas com dois fatores e quatro repetições, totalizando 32 unidades experimentais. Os tratamentos principais foram compostos pela combinação de quatro profundidades de atuação da haste sulcadora de adubo (6,5; 9,5; 12,5 e 15 cm) no processo de semeadura do milho e os secundários pelo cultivo de duas plantas de cobertura de inverno (aveia preta e nabo forrageiro). Os dados obtidos foram submetidos à análise de variância para verificação dos efeitos dos fatores profundidades de atuação da haste, plantas de cobertura do solo e sua interação. Quando o teste F foi significativo a 5% de probabilidade, as médias foram comparadas pelo teste de Tukey para os fatores qualitativos (plantas de cobertura de inverno). Para os fatores quantitativos (profundidades de atuação da haste sulcadora) e interações foi aplicado o teste de regressão polinomial. O aprofundamento da haste sulcadora ampliou a força de tração e a potência requerida na barra no processo de semeadura, bem como diminui a velocidade média do conjunto mecanizado e a força de tração específica, e apesar de gerar maior mobilização do solo na linha de semeadura não demostrou ser uma prática de manejo eficiente para aumentar a produtividade do milho. A utilização de plantas de cobertura e profundidades de atuação da haste, entre si, não modificaram os parâmetros de resistência do solo à penetração, densidade e porosidade do solo, na entrelinha de cultivo. A população final de plantas, o índice de velocidade de emergência de plântulas e os componentes de produção do milho não variaram em função da profundidade de atuação da haste sulcadora. / The system of direct sowing is characterized by the minimum tillage of the soil and maintenance of vegetal residues in cover. However, neglect with soil management has systematically provided the emergence of compacted layers in agricultural areas conducted in this system, which may lead to a decrease in crop productivity. Thus, the objective of this work was to evaluate the machine, soil and plant parameters as a function of the cultivation of cover plants and four depths of the fertilizer routing rod, in a compacted Oxisol conducted in a no - tillage system. The experiment was carried out in two agricultural crops (2013/2014 and 2014/2015) in the experimental area of UTFPR, in a dystroferric Red Latosol, with a very clayey texture (76% clay). The experiment was conducted in a randomized complete block design, and the treatments were arranged in two - factor and four replicate bands, totaling 32 experimental units. The main treatments were composed by the combination of four depths of fertilizer routing (6.5, 9.5, 12.5 and 15 cm) in the corn sowing process and the secondary ones by the cultivation of two cover crops Winter (black oat and forage turnip). The obtained data were submitted to the analysis of variance to verify the effects of the factors depths of rod actuation, soil cover plants and their interaction. When the F test was significant at 5% probability, the means were compared by the Tukey test for the qualitative factors (winter cover plants). For the quantitative factors (furrow depths) and interactions, the polynomial regression test was applied. The deepening of the furrowing rod increased the traction force and the power required in the bar in the sowing process, as well as reducing the average velocity of the mechanized set and the specific traction force, and despite generating a greater mobilization of the soil in the sowing line. Has been shown to be an efficient management practice to increase maize productivity. The use of cover plants and stem depths, among themselves, did not modify soil resistance parameters to soil penetration, density and porosity, in the intercrop line. The final population of plants, seedling emergence speed index and maize production components did not vary according to the depth of action of the furrowing rod.

16 pp. / The luxuriant tropical appearance and stately silhouette of palms add much to the Arizona landscape. Few other plants are as striking in low and mid elevation gardens. Although winter frosts and low humidity limit the choices somewhat, a good number of palms are available, ranging from the dwarf Mediterranean fan palm to the massive Canary Island date palm. This publication addresses the landscape use and the adaption of palms, as well as how to plant and take care of them. Topics include: . Landscape Use . Adaptation . Planting Palms . Care of Established Palms . Diseases and Insect Pests . Palms for Arizona . Feather Palms . Fan Palms . Palm-like Plants
