COMPORTAMENTO DO NONI À SALINIDADE DA ÁGUA DE IRRIGAÇÃO EM SOLO COM BIOFERTILIZANTE BOVINO1.

O excesso de sais no solo e em águas utilizadas para irrigação podem provocar perdas significativas de crescimento e de produção em plantas cultivadas. Dentre algumas alternativas para redução dos efeitos negativos dos sais às plantas em áreas cultivadas, a utilização do biofertilizante fermentado vem sendo explorada no cultivo de hortaliças e frutíferas irrigadas com água salina. Nesse sentido, o trabalho teve como objetivo avaliar o comportamento do noni à salinidade da água de irrigação em substrato sem e com biofertilizante bovino. Os tratamentos foram distribuídos em blocos ao acaso, com quatro repetições, utilizando o arranjo fatorial 5 x 2, correspondente a cinco níveis de condutividade elétrica da água de irrigação (0,5; 1,5; 3,0; 4,5; 6,0 dS m-1), em substratos com e sem biofertilizante bovino. Foram avaliados: altura de plantas, diâmetro do caule, número de folhas, área foliar, matéria seca da parte aérea e consumo hídrico. Todas as variáveis avaliadas foram influenciadas negativamente pelo incremento de sais na água de irrigação, mas sempre com menor intensidade nos tratamentos com biofertilizante bovino. O biofertilizante não elimina, mas atenua os efeitos negativos dos sais às plantas de noni.

Relações hídricas em cultivares de beterraba em diferentes níveis de salinidade do solo

The excess of salts in the soil can directly affect the development and yield of the plants, therefore, studies on water relationships of crops in such conditions are necessary to prevent or solve the problem. The study was conducted in a greenhouse at Universidade Estadual Paulista, Department of Agricultural Engineering, Botucatu, Brazil. The statistical design used was randomized blocks with four replications, consisting of five levels of soil salinity (1.0, 3.0, 6.0, 9.0, 12.0 dS m-1), two cultivars of sugar beet (Early Wonder and Itapuã) and two types of management of fertigation, totaling in all 80 plots. Measurements of water content of the leaves, diffuse resistance to water vapor, transpiration, leaf area and the water consumption of crop were determined. There was a decrease according to increasing salinity for the analysed physiological parameters in the Early Wonder variety while for the Itapuã variety a gradual increase was observed up to a salinity of 6 dS m-1. The water consumption by plants showed a reduction with increase of soil salinity for the two varieties.

Electrical conductivity and pH of the substrate solution in gerbera cultivars under fertigation

The quality and the profitability on floriculture are intimately linked to the adequate plant nutrition. In the present research we aimed to evaluate the electrical conductivity (EC) and pH of the substrate solution on four different gerbera cultivars subjected to fertigation, with two nutritive solutions. The experiment was carried out in a greenhouse, from May to July 2006, on the Universidade Estadual Paulista, Botucatu, São Paulo state, Brazil. The experiment was carried out under an experimental design of random blocks, in 4×2 factorial arrangement, with four Gerbera cultivars (Cherry, Golden Yellow, Salmon Rose and Orange) and two nutritive solution concentrations: 0.92 and 1.76 dS m-1 EC) during the vegetative stage, and 1.07 and 2.04 dS m-1 during the reproductive stage (S1 and S2, respectively). The nutrients were applied through fertigation, manually performed every day. The EC and pH values of the substrate solution were evaluated weekly, using the 'pourthru' method. Orange and Cherry cultivars had, respectively, the highest and the lowest electrical conductivity of the substrate solution, and Cherry was the most efficient on the nutrient uptake. The solution S2 showed a trend to accumulate salts in the substrate, but without visual symptoms of plant toxicity, leading to the lowest pH values. The 'pourthru' method was efficient when compared to the 1:2 method and can be adopted for substrate solution analysis in gerbera culture.

Análise da durabilidade do concreto de alto desempenho com adição de cinza de casca de arroz e borracha de pneu

Since the Seventies, there has been a growing degradation of concrete structures in Brazil. For that reason, much research has been made on the durability of those structures, aiming at contributing towards quality improvement and reduction of maintenance and repair costs. This study evaluates the behavior of the durability of high-performance concrete with additions, replacing part of the cement and aggregates with rice husk ash and tire rubber, respectively. Durability tests were carried out in which concrete was subjected to several degradation processes, such as the action of water, temperature, salts and acid solution. The results indicated that the addition of active silica or rice husk ash, both with tire rubber did not worsen the durability of concrete. In fact, rubber proved to be very effective in preventing the action of chemical agents, high temperatures and the penetration of water. Rice husk ash, despite the larger diameter of particles, had similar results to that of the active silica.

Sources of omega-6 fatty acids do not alter the rumen degradation and transit of fibre from dairy cow diets

The objective of this study was to evaluate the behaviour of fibre in the digestive tract on the basis of the passage kinetics of forage and concentrate particles in cows fed different omega-6 fatty-acid sources. The scientific hypothesis of this study was that omega-6 fatty acids do not interfere with the digestion of fibre in the diets of dairy cows. Five primiparous lactating Holstein cows were used in the experiment. The experimental diets were: control (C), ground soyabean (GS), cottonseed (CS), soyabean oil (SO), calcium salts of fatty acids (CSFA). The global mean estimates for the parameters of passage rate (gamma) were 0.038 and 0.055 h(-1) for forage and concentrate, respectively. The only significant effect with respect to the passage rate was a high negative correlation between the concentrate passage rate and dry matter intake. There was less undegradable neutral detergent fibre (NDF) in treatments without added lipid. Dietary supplementation with lipid sources does not alter the kinetic parameters of roughage and concentrate particle passage or in vitro NDF degradation. Sources of omega-6 fatty acids do not alter the rumen degradation and transit of fibre.
