Field experiment was carried out to study the effects of KEON and PEON (organic N extracted with phosphate buffer) from 4 kinds of organic wastes on the growth and N use efficiency of green soybean. The results show that the application of PM could apparently improve the shoot dry weight, seed protein content and the yield by 20.4%, 17.8% and 38.0%, respectively, compared with regular chemical fertilizer applied. The application of OMM could significantly improve the shoot dry weight, seed protein content and the yield by 33.2%, 16.2% and 32.5%, respectively, compared with regular chemical fertilizer applied.

Our work reported here are aiming at improving nitrogen and water use efficiency in wheat/maize, faba bean/maize, pea/maize and soybean/maize intercropping through field experiment.The main results obtained were as the following:(1) Land equivalent ratio was greater than 1.0 for faba bean (Viciafaba L.)/maize (Zea mays L.) intercropping regardless of nitrogen fertilizer application or not. Based on grain yields production, LER of pea (Pisum sativum L.)/maize intercropping was over 1.0 in spite of nitrogen fertilizer application, while LER was higher than 1.0 only when nitrogen fertilizer was applied based on biomass production. However, LER in soybean (Glycine max L.)/maize intercropping was smaller than 1.0 both nitrogen applicationa and no nitrogen application. In wheat Triticum aestivum L.
