Chickpea (Cicer arietinum L.) crop demands nitrogen fertilizer (NF) applied in excess caused lost soil fertility and environmental pollution. An alternative for solving this problem are: to reduce and to optimize NF in chickpea using inoculants based on plant growth promoting bacteria (PGPB) genus. Thus, the aim of this study was to analyze the response of chickpea to inoculation with Azotobacter vinelandii and Burkholderia cepacia at 50% reduced dose of NF. These PGPB were inoculated chickpea under an experimental design of randomized blocks. The response variables to measure the effect of PGPB on the legume were: the percent of germination, shoot and root phenotyping: plant height, root length and biomass: fresh and dry weight of shoot and root. Experimental data were analyzed by ANOVA and Tukey test. Results showed that a positive respond of chickpea to both PGPB on its germination as...

Bean is a legume its production requires nitrogen (N) combined as ammonium (NH4) or nitrate (NO3) and phosphates (NPF), its indiscriminate application causes soil lost productivity. An alternative solution for reducing and optimizing NPF is applying mixed inoculant which could be improved by plant growth promoting bacteria (PGPB) and mycohrrizae. The objective of this research was to analyze the response of beans to mixed inoculant Endospor 33® at 50% reduced dose of NPF. In that sense a red ferralitic soil poor in N and organic matter was used. By experimental design: 5 treatments and 6 replications. Results showed a positive bean responds achieving 100% germination at 20mg/seed with Endospor 33® at 50% NPF dose. At seedling level bean was 6.63g of total fresh weight (TFW) and 0.66g total dry weight (TDW) with the same Endospor 33® dose compared to 0.28g of TDW of bean used as relati...
