| Abstract: The objective of this work was to evaluate different pruning times, performed before or after natural leaf drop, regarding their effects on the yield of 'Royal Gala' apple (Malus domestica) trees. The experiment was carried out in Vacaria, in the state of Rio Grande do Sul, Brazil, on seven-year-old trees in four harvests from 2008/2009 to 2011/2012, using a randomized block design. The following pruning times were tested: 46 days before leaf drop (DBLD); 25 DBLD; 5 DBLD; 15 days after leaf drop (DALD); 36 DALD; 55 DALD; and 75 DALD. All pruning times before natural leaf drop reduced yield per tree and fruit set. Among the pruning times before leaf drop, 46 DBLD resulted in the lowest yield. Pruning performed after natural leaf drop, still during... |

| ABSTRACT In this work, two cultural production systems were compared [conventional (CO) and organic (OR)], and its effects in the guava trees (Psidium guajava) bacterial blight (Erwinia psidii) control. The experimental design was in radomized blocks, in split-split-plot arrangement, where it was measured the bacterial disease and the fruits production on the 2005/06, 2006/07 and 2007/08 harvests. Four pruning seasons effects were evaluated on the harvests (September, December, March and June) in both production systems. Such systems were constituted of: OR – treatment with bioactive compound (BC), liquid BC and dead coverage, and; CO – chemical fertilization, fungicide and herbicide. In 2007/08, the area under the disease progress curve (AUDPC) of all... |
