Despite relatively low seed yields, or perhaps because of them, there are few reports from Australia of responses by mungbean to fertilizers or soil amendments. Reports from elsewhere that fertilizer treatments in experimental plots have increased seed yields by up to 830 kg ha-1 in green gram and 1170 kg ha-1 in black gram suggest that fertilizers or soil amendments have the potential to markedly increase mungbean yields. However, the full benefits of improved mineral nutrition are unlikely to be realized unless the yield potential is also increased by improved cultural conditions and genetic potential. Field trials, pot trials, plant symptoms and plant analysis have all been used for the diagnosis of nutrient disorders in mungbean but further work is needed to develop standards for macronutrient deficiency diagnosis. Moreover, there are few sailor plant analysis standards available to predict the occurrence of nutrient disorders or fertilizer requirements in farmers' mungbean crops. In addition to nutrient disorders that limit seed dry matter in mungbean, those that limit symbiotic N2 fixation (deficiencies of Mo, Co, Ca, Fe, and possibly P and Cu, and toxicity of AI) or seed quality (E) require special attention.
