| The objective of this study was to evaluate the effects of poultry litter and Organosuper® with three modes of application on the biomass production and nutrient content of the leaves of roselle plants. The treatments in each crop cycle were in a factorial arrangement, 2 x 3 + 1, composed of a control and combinations of the two organic fertilizers (poultry litter (10 ton. ha-1) and Organosuper® (10 ton. ha-1) and the three application modes (surface, incorporated and surface + incorporated), in a randomized block design with four replicates. In the surface + incorporated mode, the organic fertilizers were applied as 5 ton. ha-1 surface and 5 ton. ha-1 incorporated. The highest productions of fresh and dry weight and number of calyxes were obtained for... |
