Key words: Sulphur fertilization, wheat seed rate, wheat/faba bean intercrop, conventional system, organic system.


Two field experiments carried out in contrasting production system (conventional versus organic) investigated the effects of sulphur (S) fertilization and wheat seed rate in wheat/faba bean (bean) intercropping system. For the conventional experiment, S fertilization reduced wheat seed yields and biomass yields substantially. Continue reading
