The necessity to increase the production of food, fibers, agroenergy and other farming products to serve the growing world population stimulates the efficient use of corrective treatments and fertilizers and the search for alternative solutions, as, for instance, the use of steel slag. The use of slag-based products in soil becomes an important resource for the decreasing of environmental impacts caused by storage and the final disposition of its raw material, which also converts into a viable source of income for the steel industry. Another factor of important vegetal production is the use of water, which has a fundamental role in the development of plants, that comes from being the main carrier of soil nutrients, aside from participating in a myriad of physiological functions. Thus, a scenario of hydric restriction causes plant stress and turns into one of the prime reducers of agricultural productivity. In light of the above, this paper had as its purpose evaluating the influence of the application of calcium silicate and magnesium, derived from steel industry residue, over the resistance to the hydric stress of the Brachiaria brizantha cv. Marandu forage, in accordance with the hydric provision available for this culture. The experiment was conducted in a greenhouse following a split plot design, with each plot carrying silicate and the subplots the water blades assessed (100%, 80%, 60%, 40% and 20% of the Field Capacity - FC), in an entire randomized design with four repetitions.

The aim of this study was to assess the influence of different exposure times of engorged female the Rhipicephalus microplus to infective juveniles of Heterorhabditis bacteriophora isolate HP88. The engorged females were divided into seven groups (six treatments and one control) of 20 ticks each with statistically similar average weights (p > 0.05) and exposed to concentrations of 300 nematodes/tick for periods of 3, 6, 12, 24, 48 and 72 h. The following biological parameters were monitored: pre-oviposition period; egg mass weight; hatching percentage; and efficacy of treatment. There was no influence of the exposure time on the pre-oviposition period (p > 0.05), while there were significant differences (p < 0.05) between the groups exposed for 24, 48 and 72 h and the control group with respect to the egg mass weight, and 24 h for hatching percentage. Treatment efficacy reached 100% after exposure for 48 and 72 h. These results demonstrate that infective juveniles of H. bacteriophora HP88, under laboratory conditions, interfere in the majority of the biological parameters of the non-parasitic phase of engorged R. microplus females when the exposure time is greater than or equal to 24 h. |
