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.

Este trabalho foi realizado pela EMBRAPA/UEPAE de Pelotas com o objetivo de analisar as variacoes que ocorrem na cultura do sorgo granifero (Sorghum bicolor L.), quanto ao rendimento de graos e outras caracteristicas agronomicas, quando e novamente cultivada a semente colhida do hibrido, ou de uma geracao subsequente. O experimento foi conduzido de 1980 a 1982, no campo, no esquema de parcelas subdivididas em blocos ao acaso, com quatro repeticoes. As cultivares Agroceres 1002, Pioneer 8311, BR 300, BR 301 e TE Y 101 formaram as parcelas, e as geracoes F (ou hibrido), F2, F3 e F4 formaram as subparcelas. Observou-se que as geracoes posteriores ao hibrido (F1) foram muito variaveis quanto a caracteristicas agronomicas, principalmente ciclo e altura de planta, o que dificulta a colheita mecanica. A geracao F1 ou hibrido foi significativamente superior em rendimento e estabilidade de producao. As sementes adquiridas todos os anos (de uma cultivar uniforme) sao as que oferecem menor risco e maior rentabilidade ao agricultor. |
