- W4220797237 abstract "Abstract Aims There is a growing interest in developing ecological agriculture in order to achieve cleaner production and pollution reduction related to the use of chemical fertilizers. The present research goal is to compare the effects of chemical fertilizer such as urea, in comparison to biofertilizer based on bacterium Azotobacter sp., on the growth of cowpea bean (Vigna unguiculata L. Walp). Method A small block experimental design was used, in which the concentrations of chemical fertilizer such as urea and biological fertilizer Azotobacter sp. The dosages of the fertilizers were varied to evaluate the dependent variables such as the length of the aerial part (LAP), root length (RL), fresh weight of the aerial part (FWAP), dry weight of the aerial part (DWAP), root fresh weight (RFW), root dry weight (RDW) and stem thickness (ST). Results It was demonstrated that the optimal dosage was 1.9x10 9 total cells contained in 1 mL of biofertilizer Azotobacter sp getting an average length of aerial part (LAP) of 16.333 ± 0.757 cm. While with urea, we have obtained length values of aerial part of 14.267 ± 0.850; 15.767 ± 0.987; 15.567 ± 1.041cm for fertilizer dosage volumes of 1, 2 and 3 mL respectively. A control test without fertilizers was carried out for comparison. Conclusions In conclusion, the replacement of urea with the biofertilizer Azotobacter sp. is feasible, being a viable alternative to reduce soil and environmental pollution." @default.
