Abstract

VA Mycorrhizal (VAM) fungi could increase leguminous plant growth by enhancing nutrient absorbtion ability. The effectiveness of the VAM fungi was influenced by three main factors: (1) The different types of VAM fungi varied in their effectiveness with regard to Thai conditions and in reference to the growth of a number of economically important leguminous cash crops including peanut, soybean and mungbean. (2) In fertile soils the response to the use of VAM fungi could often be minimal; best results were obtained from soils with a high level of nutrients in unavailable forms. (3) If the indigenous VAM fungi were already effective little response may result from applying more VAM fungi to the soil. The paper described the importance of the above three factors on the effectiveness of the VAM fungi with regard to Thai conditions and in reference to the growth of a number of economically important leguminous cash crops including peanut, soybean and mungbean.
