چکیده
Numerous studies reported the positive effect of soil amendment with biochar on plant development. However, little is known about and its interrelation nitrogen (N) phosphorous (P) additions their impact growth. We carried out greenhouse experiments to understand interactive effects phosphorus supply, as well amendment, symbiotic performance soybean (Glycine max L.) Bradyrhizobium japonicum, growth nutrient uptake. The was produced from maize by heating at 600 °C for 30 min used pot an application rate 2%. Plants were fertilized two different concentrations P (KH2PO4) N (NH4NO3). Biochar significantly increased dry weight root shoot biomass, 34% 42%, under low respectively. japonicum inoculation enhanced biomass significantly, 41% 67%, in without addition, nodule number 19% higher plants grown combined or high P, than combinations, while roots. Moreover, uptake all treatments compared B. japonicum-inoculated uninoculated plants. A statistical difference between levels observed supply soil. Our results show that interactions nitrogen, phosphorus, affect improving nutrition soybean. strong correlations These data indicated use N, can be effective approach minimum input.
