| The study was carried out from May to November 2012 at the Cascata Experimental Station of Embrapa Clima Temperado, Pelotas, RS. The aim was to evaluate the effect of organic nutritional sources on the growth, development and production of "Coração de Boi" cabbage. A randomized block design was used, with five replications and seven treatments. The experiment was carried out to fertilize the cabbage with fertilizers obtained from different organic waste, and the following treatments were used: control; boiled poultry litter; boiled cattle manure; liquid humus; solid poultry litter; solid cattle manure; solid humus. The following variables were assessed: plant growth; cycle; compactness; leaf area; leaf area index; fresh mass, dry mass and DM content of the outer leaves and head of cabbage; heart length, transverse and longitudinal diameter, ratio between length and longitudinal diameter, shape index, volume and yield. It can be concluded that the treatments based on poultry litter, both in liquid and solid form, have potential for the growth, quality and production of the cabbage crop. |
