| Resumo: |
Due to the increasing need for forest roads, parks and gardens with good quality seedlings, the study aimed to evaluate the initial development of seedlings of Bauhinia variegata L. and Ceiba speciosa (A. St. Hil.) Ravenna in different proportions bed aviary on the substrate. To this end, it tested five substrates made from bed aviary: T1: commercial substrate (CS) control, T2: 33.3% of soil (S), 33.3% sand (SA) and 33.3 % Bed aviary (BA); T3: 25% S, 25% SA, 50% BA; T4: 16,6% S, 16,6% SA, 66,6% BA; T5: 100% BA. From the results, it is concluded that all substrates studied were shown to be suitable for the development of seedlings of B. variegata and C. speciosa, however, the use of bed aviary becomes interesting in the production of seedlings, therefore, the incorporation of this organic material, in addition to adding nutrients to the plant compounds, combines the optimization of the proper disposal of this waste, and the steady supply in the region makes it economically attractive.
The aim of this study was to evaluate the initial development of seedlings of Bauhinia variegata L. and Ceiba speciosa (A.St.Hil.) Ravenna under different rations of poultry litter on their substrate. The five substrates formulated from poultry litter were: T1: control substrate (SC); T2: 33.3% (S) soil, 33.3% sand (A) and 33.3% % of poultry litter (CA); T3: 25% S, 25% A, 50% CA; T4: 16.6% S, 16.6% A, 66.6% CA; T5: 100% CA. The variables analyzed at the third month of the seedlings were: colon diameter (DC), height of the seedlings (H) and number of leaves (NF), relationship between height and colon diameter (H/DC) (MSA), roots dry mass (MSR), total dry mass (MST), relation between shoot dry mass and root dry mass (MSA/MSR) and Dickson Quality Index (IQD). The analysis of the results was performed statistically in terms of variance (ANOVA) and test of comparison of means, for which the Tukey test was used, with a confidence level of 95% using the software Assistat 7.6 beta. From the results, it can be concluded that all substrates studied were suitable for the development of B. variegata and C. speciosa seedlings. However, the use of poultry litter becomes interesting in the production of seedlings. The incorporation of this organic material, besides adding nutrients to the substrate, optimizes the correct destination of the same and reduces the cost of the substrate.
