| Two experiments were carried out to study the effects of grinding of soybean hulls (SH) on starting pigs (15-30 kg) diets. Experiment I consisted of a digestibility trial with 12 barrows, initial average body weight 21.9±1.29 kg, in which the best digestibility coefficient (DC) of DM and GE was obtained with SH ground through a 2.5mm screen mesh, evaluated for CP and ME, a best DC was attained with 3.0 mm screen mesh. In the Experiment II, five diets with increasing SH (2.5 mm) levels (0, 3, 6, 9 and 12 %) for starting piglets were formulated. A quadratic response in daily weight gain (DWG) occurred, according to SH inclusion. Worst DWG occurred at 7.75 % SH inclusion. Daily feed intake, feed: gain ratio and plasma urea nitrogen were not affected by... |

| Com a premissa de que a utilização de hidrogel associado à calagem e adubação em plantios de eucalipto aumenta a retenção de água e o teor de nutrientes no solo, objetivou-se avaliar a sobrevivência e o desenvolvimento inicial de clones híbridos de Eucalyptus grandis x Eucalyptus camaldulensis, em função da utilização de hidrogel, calagem e adubação. Em um Argissolo Vermelho, foram dispostos os tratamentos: 1) controle, 2) hidrogel, 3) adubação convencional, 4) adubação + calagem, 5) adubação + hidrogel e 6) adubação + calagem + hidrogel. Foi utilizado o delineamento em blocos casualizados, com seis repetições e seis plantas por parcela. Avaliou-se a sobrevivência, a altura, o diâmetro do caule, o teor de macronutrientes na parte aérea e atributos químicos... |

| ABSTRACT: The boundary line is a method frequently used to assess the nutritional status of plants when the relationship between the variables under analysis is influenced by other interacting factors. The objective of this study was to propose and test the boundary line model to estimate the nutrient sufficiency range and nutritional status of irrigated muskmelon. The lower and upper limits of the sufficiency range were calculated as a basis for assessment of the nutritional status of muskmelon. Leaf material was collected from 70 muskmelon crop areas in northern Brazil. The nutrient (N, P, K, Ca, Mg, S, Fe, Zn, Mn, B, and Cu) concentrations in the leaf tissue and the respective fruit yield of each area were measured. The proposed model to estimate the... |
