<b>Biological fixation of N₂ in bean plantation at doses of inoculants and chemical treatment to the seed compared with nitrogenous fertilization</b> - DOI: 10.4025/actasciagron.v29i4.416

Abstract

The inoculation of bean is a technique spread out by research, but it is not very much used by farmers. However, considering the low purchasing power of the majority of farmers who cultivate beans and the low average productivity, the use of this low cost technique can be an excellent alternative to increase productivity.The aim of this work was to evaluate the inoculation with Rhizobium and the nitrogenous feeding of beans. The experiment was conducted in 2004, in Colorado, state of Paraná. Results showed that inoculation was an efficient technique in supplying nitrogen to the culture, when compared with the addition of mineral nitrogen. The “carioca” bean variety showed positive response to the inoculation with good levels of nodulation and yield. The increase of inoculation level did not result in nodulation and productivity gains, though the use of fungicide in the seed affected the productivity.
