Desenvolvimento radicular e aéreo, nutrição e eficiência de absorção de macronutrientes e zinco por cultivares de arroz de terras altas afetadas pela adubação fosfatada

In Brazil, phosphorus availability is one factor that that more limit yield of upland rice under rainfed system. Then, better understanding of cultivars development at phosphorus soil fertilization is very important in the production systems making this more sustainable. The objective was to evaluate the influence of phosphorus doses applied to the soil over the root length, root and shoot dry matter, concentration and content of macronutrient and zinc in shoot and root as well as the efficiency of nutrient uptake per meter root of upland cultivars of intermediate and modern groups. The experiment was carried out in greenhouse conditions in a completely randomized design in factorial scheme 4 x 4. Treatments were four levels of P fertilization applied at the soil (0, 50, 100 and 200 mg dm(-3) of P) and four upland rice cultivars (Maravilha - modern group, IAC-201, IAC-202 and Carajas - intermediate group). There is increase in phosphorus availability in the soil with increasing levels of P fertilization. Under low phosphorus availability, cultivars of the intermediate group have better shoots and root system development in relation to the modern cultivar group. Level of phosphorus affected nutrients contents in shoots and root system of upland rice cultivars. The increasing phosphorus fertilization increased uptake of nutrients per meter of root; and although under higher phosphorus availability there was a greater root growth, in low phosphorus availability root growth was greater at the expense of shoot growth.

Cuidados essenciais e muitas vezes negligenciados na hospitalização de pequenos animais: nutrição e analgesia

The benefits of proper nutrition and analgesia are closely linked when it comes to animals that are suffering from any illness and are hospitalized. In patients who are ill or under the stress of hospitalization, increase secretion of glucagon, catecholamines, cortisol and growth hormone antagonize the effects of insulin, leading to hyperglycemia and degradation of tissue proteins to provide substrate for gluconeogenesis. These changes result in loss of lean body mass, reflecting negatively on tissue repair processes, immune response and prognosis. Likewise, the pain induced by noxious stimulation can lead to protein catabolism, stress, immunosupression, delayed wound healing and acceleration of disease processes. This review confirms the nutrition and pain control importance in hospitalized patients, showing their physiological benefits and reduction in hospital stay when the clinician understands these benefits and the animals are treated with such care

Acurácia da mosaicagem gerada por veículo aéreo não tripulado utilizado na agricultura de precisão

The need for unmanned aerial vehicle (UAV) is a Brazilian reality in the worlds agricultural, once they have models penetrating the market with agrictural purpose. After processing, the images collected by a UAV can generate a mosaic of the study area. For making and georeferencing the mosaic, can be deployed or not ground control points. Thus, the study aimed to compare a mosaic with ground control points and without ground control points generated from images collected by a UAV used primarily for agricultural purposes. The results showed that the quality in the determination of areas and perimeters no presented significant difference with or without the use of ground control points. The mosaic generated without ground control points obtained an average error of 23.7% of the pixel size; with ground control points, the average error was 10.6%, providing an improvement of approximately 50%. Planimetric and altimetric errors, with respect to the ground control points, for the controlled mosaic, reached the order of decimeters, with planimetric accuracy of 12.8 cm, a result considered satisfactory taking into account mainly the purpose of assessed UAV
