Information about the selection of growing media for inexpensive organic passion fruit production systems is an important advance, considering the lack of reliable information. Thus, we evaluated different formulations of growing media for these systems to identify which provides better germinative vigor and root and shoot growth of Passiflora edulis Sims. The experimental design was completely randomized, composed of 40 growing media containing different proportions of coconut fiber, manure, organic compost, soil, and vermiculite. Germinative vigor and seedling growth parameters were evaluated at 60 days after sowing. The data were submitted to multivariate analysis and the groups formed were submitted to analysis of variance. Based on principal component and cluster analyses, five groups were identified with the best performance of the seedlings grown in the growing media of group 4, with emphasis on the formulations using coconut fiber and vermiculite in the proportion (volume) of 45% of each plus 10% organic compost (T11), and soil with coconut fiber in the proportion of 40% of each plus 20% organic compost (T4), which produced the best development of the seedlings? aerial parts and roots. Therefore, group 4 growing media, in particular T11 and T4, are recommended for the production of yellow passion fruit seedlings. |

Tropical flooded rice production systems require a high input of fertilizers and chemical defensive. The use of plant growth-promoting rhizobacteria (PGPR), a sustainable component of this system, can increase nutrient-use efficiency and lead to significant increases in the grain yield of tropical flooded rice crop. This study aimed to determine the effect of the microorganism BRM 32110 (Bacillus thuringiensis) in combination with nitrogen (N), phosphorus (P) and potassium (K) application rates on the physiological and agronomic performance of tropical flooded rice plants. Trials were performed in the 2016/2017 growing season in Formoso do Araguaia, a city in Tocantins state, Brazil. Three independent experiments (E1, E2, and E3) were performed in a randomized block design in a 4 x 2 factorial scheme with three replications. E1 comprised four N application rates (0, 40, 80 and 120 kg N ha-1) with and without the addition of BRM 32110, E2 comprised four P2O5 application rates (0, 40, 80 and 120 kg P2O5 ha-1) with or without BRM 32110, and E3 comprised four K2O application rates (0, 20, 40 and 60 kg K2O ha-1) with and without BRM 32110. In fertile soil, there were no interactions between the rhizobacterium BRM 32110 and the N, P or K application rates. BRM 32110 improved nutrient uptake and, on average, increased shoot dry matter by 8%, photosynthesis rate by 14% and grain yield by 11% in the flooded rice plants. Our results suggest that the use of multifunctional microorganisms is a good strategy for improving flooded rice grain yield sustainably.
