The application of paclobutrazol (PBZ) by irrigation system to induce the flowering of mango may be an economically and environmentally more efficient practice. The objective of this work is to determine the most efficient dose of PBZ to be applied by irrigation system to manage the production and quality of fruits of the mango cultivar ?Tommy Atkins? in the middle region of the São Francisco Valley. The experimental design was randomized blocks with five paclobutrazol doses applied by irrigation system (0.5, 1.0, 1.5, 2.0 and 2.5 g a.i.-1, linear canopy) and an additional treatment (control) with the application of a dose using the conventional form (2.0 g a.i.-1 linear canopy applied manually by haul), and four replications. The variables analyzed were number of panicles, panicle length, number of fruits per plant, average fruit weight, production per plant, economic viability, and qualitative characteristics of fruits. The application of paclobutrazol by irrigation system is more efficient than the conventional application, in which the dose 1.4 g a.i.-1 linear canopy provided a greater number of fruits and a greater production per plant. The highest content of total soluble solids in fruits was obtained at the dose 1.3 g a.i.-1 linear canopy, and acidity decreased as the applied dose of PBZ increased. Regarding the economic analysis, the results show that the application of PBZ by irrigation system increases the revenue by R$ 5,328.00 per hectare in comparison with the conventional application.

Grazing strategies promote changes in sward structure that can affect patterns of herbage accumulation and sward flexibility to management. This experiment evaluated sward structural characteristics and herbage accumulation of Mombaça guinea grass (Panicum maximum Jacq. cv. Mombaça) subjected to rotational stocking managements. Treatments involved grazing when swards reached either 95 or 100% interception of the incident light (LI), to post-grazing heights of 30 and 50 cm, and were allocated to 2,000 m² paddocks according to a randomised complete block design in a 2 × 2 factorial arrangement with four replications, from January 2001 to February 2002. Sward canopy changed from a vertical to a more horizontal orientation as the light interception area index and height increased from post to pre-grazing. Leaf canopy height pre-grazing was stable throughout the year and around 90 and 115 cm for the 95% and 100% LI treatments respectively, indicating a potential for development and use of target-based grazing management practices. Herbage mass pre and post-grazing was lower for the 95% than the 100% LI treatments, but with higher proportion of leaf and lower proportions of stem and dead material. Treatment effects on herbage accumulation were cumulative and became more evident as the experiment progressed, with up to 6 t ha-1 DM advantage to the 95/30 treatment. Although based on a single year experiment, grazing management should aim for low herbage mass during the transition period from winter to spring in order to allow fast recovery of swards and favour herbage accumulation during the following growing season.
