Desenvolvimento e produção de plantas de pimenta rosa (Schinus terebinthifolius Raddi) cultivadas em solo com resíduos orgânicos adicionados de diferentes formas

Abstract

The aim of this study was to evaluate the development of plants and production of pepper fruits cultivated with organic waste and addition of different forms of soil. The cultivation was carried out in soil using the following organic residues: semi-composted chicken litter and OrganoSuper® compound, added in cover (10 t ha-1), incorporated (10 t ha- 1) or in top-dressing (5 t ha -1) + Incorporated (5 t ha-1). The treatments were arranged as factorial 2 (residues) x 3 (addition form) + 2 (controls, without residue), in a randomized complete block design, with five replications. The evaluations of height, diameter, number of leaves and SPAD index Were performed at intervals of 15 days to 225 days at transplanting. The fruits of pink pepper were harvested at 230 (DAT) days after transplanting the seedlings. Two competitive plants of each plot were harvested at 260 (DAT) for biomass of leaves and stem and quantification of leaf area. The plant height ratio/ Stem diameter and, the dry leaves of leaves and stems were not influenced by any of the factors under study, making averages of 7,93 cm; 96,06 g / plant; end 26,50 g / plant respectively. For the fresh masses of leaves, stems and foliar area the highest values were obtained with the addition of OrganoSuper® in the incorporated form plus coverage, reaching values of 731,80 g / plant; 990,30 g / plant and 14600,97 cm2 / plant, respectively). The use of organic residues gave rise to better growing plants and larger yields of fresh stalks, leaves and fruits. Comparing the two organic residues, Organosuper® resulted in better production of pink pepper fruits than the chicken bed in the incorporated form.
